A

Good morning good afternoon, good evening and welcome to another edition of the level up hour here on openshift tv, I am chris short executive producer of openshift tv and I am joined by the one and only the illustrious langdon white langdon. How are you today, sir.

B

ah Not too shabby uh we, uh you know as always, are concerned about our coffee intake. um Yes, but you know I was uh just talking to my wife, uh whose idea was it to do it 9am show exactly, um and then I realized, I think it was mine.

A

Yeah, it's all your fault.

B

So I think it is my fault. uh So today is the level up hour: um let's introduce quickly with the slides, uh because everybody loves some slides. um Who was I talking about slides with the other day?

B

I don't know, but so this is the level up hour where we talk about, why containers are fun and amazing uh and show you how to uh you know, use them for kind of your everyday stuff um and then kind of by extension, uh why you might want to orchestrate them using something like openshift uh when you run into uh kind of the growing pains that you might run into with using um uh containers directly.

B

Although we've had I've actually had a bunch of discussions lately on the show, I think even about discussions where you know. Sometimes you actually just want to do orchestration with like podman and yaml right, um and that looks like it's going to get even better in podman v3.

A

So I'm really excited for batman, 3.

B

Yeah, so I was going to say like um let's do the slides and then I want to talk about some like announcements, um but uh so find us on twitter. I'm langdon with one and chris is chris short. uh All one word, um you don't have to get the casing right. We just do that. So it's readable um and you can join us on our discord. uh We're usually around and uh you know that's uh you know it seems to be the cool kids uh hangout place.

B

um It is, I don't know it's a trade-off against slack, um but uh you know it still has the uh it.

A

Has the voice capabilities that are like.

B

Yeah than slack, if you like but yeah, it is.

A

You know it's pick your messenger to juror right right.

B

Right, my uh one of my children actually just uh hangs out like basically as soon as school is done, jumps into minecraft, hangs out with his friends, and it's been actually a real blessing uh in the kind of pandemic uh scenario where he can't go see his friends, but he is literally on audio and chat with them. You know for hours at a time when they're all kind of playing minecraft they talk about school work all this stuff. It's really it's really quite interesting. um Wow.

A

That's that is interesting.

B

Yeah it's like they're like chatting and stuff too, like community they've built yeah, that's awesome! Yeah! um They have you know they have some people who kind of come in and out it's. It's really like. I said quite interesting, there's like a whole sociological study uh to be seen. I think in this uh environment uh that oh, absolutely yeah, if I was in in that educational field, I think it'd be interesting. um So uh jp dave makes an interesting point, but let's I gotta get through the slides all right.

B

So um today uh we apparently terribly named uh the level of our in the it's not.

A

Terribly named, I was just I came off of four days of pto and I was super confused when I saw the intro right for this.

B

Episode yeah, so I um I got it from somebody else too. uh They were like wait. So are you doing like a crossover within the clouds.

A

And uh you know, I don't.

B

Know if anybody ever watches, I think it's the cw uh channel, um but they always hype like crazy. Their crossover event shows um yeah, and uh so maybe we need to do a bunch of some crossover progress.

A

I'd be all for that yeah yeah.

B

So uh so that should be uh so, but what we're actually talking about today is uh the developer sandbox, which is a way that you can for free uh check out uh the developer. uh Sorry open shift kind of in the cloud in a way where you click a button, and it goes instead of having to build it yourself um and, uh and so that's what the in the cloud part is. uh But you know you got to get those buzzwords in there.

B

You got to drive that traffic, so uh you know cloud, uh you know synergy. um You know, oh.

A

No, no, don't just start that. No, I did say I spent.

B

A lot of time in consulting um so uh the other thing is, as I try to do every week um or every episode. I try to do, show notes um and we appreciate.

A

Those show notes. Yes, we do.

B

So I uh missed whatever I was like two weeks behind or something so I kind of banged through those, and uh they are. I just linked them, not very prettily um in the chat, um but.

B

There they are a little bit more nicely, so go check.

A

B

File an issue filing problems uh like I said I try to recap uh what we talked about and then at least for me somewhat. More importantly, um I try to also give reference links. So if you want to know more about a particular subject, go here kind of thing.

B

So that's it for slides, because the next one is the internet points. So we won't show those yet, but I did want to uh like, I said, make a couple announcements. So, first and foremost, we are dark next week. Yes for no particularly good reason, except that it's st patrick's day and that's a very popular holiday, normally in my community, like in my neighborhood, um but actually the reason yeah.

A

You know fair enough, you know I got a day off.

B

Well, I was not even um it's.

A

Good okay, like is it gonna, be like a huge block party kind of thing well,.

B

So there normally would be. We have one.

A

B

Biggest parades in the country, um usually next week like.

A

On your street right, yeah yeah, like it kind of goes.

B

Like down my not down my block for the next block over, um and so it's uh you know, it's a big deal, but given pandemic everything's cancelled, um you know, I guess maybe maybe it was some level of hope. I don't know um so we yes jpd there are. There are irish people in boston, um but uh what's particularly funny is actually when I moved here and I've been here.

B

uh I've been in this neighborhood for so south boston for 15 years now um that apparently there are bartenders and like wait, staff that uh fake an irish accent uh because they get better tips.

A

Because they're irish for the.

B

Neighborhood yeah, which I think is hilarious, uh more power to them. Don't get me wrong. um You know it's.

A

Interesting that they get like not called on it right, you would think.

B

Well, I mean clearly they've.

A

Been practicing so.

B

Good well and clearly, americans are excellent at recognizing accents. You know.

A

B

Outside of america, oh.

A

I can't say: half the words in the english dictionary because of my upbringing.

B

That's right um yeah, so I always thought I thought that was pretty funny, but uh uh so dark next week, but the week after we are going to have on the show one of the lead- architects, brent bowdy um of podman v3, um and so we are very much looking forward to that uh he's a really good guy uh for one thing, and it should be really interesting to talk about what's new in b3, um because we are uh very excited for it.

B

um I think you know we talked about it a little bit in was it last episode. We didn't watch the one before that. um uh I think it was the last time.

B

Oh, it was a one before that, because we did subscriptions last time and before that we did uh sc linux um and he was talking about uh because my big question about v3 was why three like what made the x bump and it's really about the api interface, but from a user perspective or you're, the casual user perspective, um uh there's a ton of new features, so we're really looking forward to it um and narendev asks. If irish people speak english or welsh, uh actually they speak neither they speak irish.

B

uh They usually also speak english, but seldom would they speak welsh. Yes, yes,.

A

B

Speak welsh primarily um and uh you know, but I think if you were kind of standing around and there was uh one group of people speaking welsh and another group- people speaking irish, I'm not sure you'd be able to tell unless you knew one of the one of the languages.

A

It's like uh what is it german and dutch, it's like.

B

Yes, right, like one is a lot of similar, sounds yeah um so uh and then we have oh, my hey boho how's it going uh so we have uh mo duffy who actually speaks irish on the show uh and is making comments in the chat in irish um wow, good job.

A

The thing I learned.

B

Actually relatively recently is, I guess, um and you know feel free to correct me. I can't quite remember how this works, but so, like gaelic, is not irish gaelic is that is different. Yeah like I now can't remember it doesn't matter. That's.

A

Not what the show is moving. This is.

B

Not an etymology or uh you know like a linguistic show, um but uh you know so, even though we we get into all kinds of random uh commentary, um so jp dave did bring up uh another point kind of very early in the chat which was we should write up the discussion about. We had quite some time ago uh on one of the episodes about v8 and about using- uh and I don't mean the uh you know, tomato drink. I mean the.

A

The engine, the engine for the engine, yeah.

B

For javascript um and about getting that on uh rel, uh so apparently that is a not a well-known subject. um So uh yet yet another thing for me to add to my list of things to do so.

A

We're, like you, have a team of people.

B

Right right that.

A

Where they're all right there in the channel with us.

B

Yeah, that's true. I would love to see jp dave write us a blog post that about it and I will make sure it gets published.

A

Like and maybe we'll even publish them I'll level.

B

Up our code on it and then uh and then people can get points we're going to uh read it.

A

But I know jp date is busy and and.

B

Like I said like we have a team.

A

Literally of people that we work with that could help us with that too.

B

That's true, that's true,.

A

The developer advocate team could certainly take that on yeah.

B

Yeah, I feel like maybe.

A

Faster than you could potentially.

B

Potentially, potentially um so, okay long story short talking about developer sandbox today, um so my inclination is to share and we're going to try to have both of us play with this today, which is not our normal kind of scenario, um but so I'm just gonna do I obviously have uh some stuff already set up, but um I'm kind of gonna do what all of you all would do? uh Oh, not even I was gonna go further back than that um hold on one. Second, we share.

A

Yeah, so the dev sandbox we've talked about it. I think briefly on the show before, but if you want to get your own two-week instance of the uh full openshift, uh you know container platform uh go to the link. I just dropped in chat and you will be able to just log in with a free developer, uh red red hat, developer, login and off you go, but.

B

Given the likelihood that you've, oh boy, am I on mute, no.

A

B

You're good uh so, but given the likelihood you're gonna forget that link, uh you know, do what I do, which is you, google, red hat, developer, sandbox and look at that. The first result. First, and so, if you are here, uh you will not immediately see this. This is because I've already kind of engaged it, um but basically what you have to do is you kind of log in? If you don't have a developer sub it'll make you fill out some t's and c's that kind of thing uh it's pretty low uh barrier to entry.

B

I think you can also social login. uh You know where social is github um as well as a bunch of other stuff, uh so use whatever you like. um I just from my own experience. I have always created like personal email address based developer logins, because then they can survive like leaving companies or coming.

A

Back to companies.

B

um You know so you know, like I said your mileage may vary, um but you know here's here's kind of how you get going, um but then you say start using your sandbox um and this is gonna go much faster for me in theory than it will for you, um because I already did it once today.

B

So hopefully it will come along pretty quickly, um and one thing I did want to point out is that there was another episode. Sorry another show entirely about the developer sandbox. I don't know. Maybe a month ago.

A

It was less than a month ago we had like we've done a couple, not sessions with the developer toolbox. We've talked about it on many many shows. Okay. So don't like it's it's a known thing on the channel, but this is our first time like just kind of like getting in and just digging right right.

B

So the first thing that I want to point out is that um okay, so my username here is just langdon, um and so it generates three different. uh What are called you know open shift projects. You know we talked about these before, um but it creates this code, one a dev one and a stage one uh to try to kind of start to set up that ci cd um kind of scenario. For when you want to build something out, I don't think we're going to get that sophisticated into it today.

B

But you know the idea, that's kind of the idea, um but the first thing I think I was going to show maybe show.

A

Well, can you do me a favor and do this for narendra real, quick, quick, open your login name sit.

B

A

Right yep, your your login name; click that down arrow yep and then dev sandbox.

B

Right yeah, one thing this is uh annoying. I know this is in progress, make sure you click dev, sandbox, yeah,.

A

That's the big thing in all of this, so it don't don't don't don't click that norendov. If you click that display token thing, it will give you your credentials for the command line. You don't have to set any environment variables or anything like that. You can just go ahead and.

B

Log in I actually just did that trying to think how I could uh yeah. I was trying to what it's doing.

A

How to show you.

B

What to what it'll show you without showing you.

A

Well, I mean I have like it on my screen, but I would want to like scroll off the actual command. I ran.

B

Or just just like mess up the token.

A

Yeah, I could maybe do that, but like it here, I can share a screenshot just as easily as I can share anything else, but you.

B

A

um Essentially, you it's an oc login with a unique token to a server path uh and it tells you like boom. This is your thing. You know that you're writing on six. Four four three, as you know, from ec short using the token provided and you have access to the following projects and can switch between them with oc project project name, and you have three projects that are created. uh Your login name, dash code, dash, dev and dash stage. Thinking through your you know, deployment process exactly.

B

A

Your default logged into the code project.

B

No, no actually weirdly, uh or at least for me it always comes up with the dev project. It always goes up in the middle. I don't know why um uh so one other thing I wanted to point out too, is um it's always a good idea under this question mark to go to command line tools here and get right version oc here right, and so we talked about this a few episodes ago with the oc clients. um Oh sorry, uh oh I.

B

What did I call it open shift, clients uh container so that you could actually switch between them. uh So that's one. uh That's kind of another approach to the same thing, um so somebody asked in the chat about pricing, so um oh jp did kind of answered it. uh So there there is a developer subscription now that developer subscription.

B

Actually I mean it's been around for years and years, but that developer subscription now includes 16 production installs of rel, but it also includes access to actually a ton of content in the customer portal, as well as a ton of content on the developer site. I don't know how much the developer site is actually paywalled and when I say paywall I just mean you have to log in first and then the also gives you access to this developer sandbox.

B

All of these uh that subscription is currently a note. Like is no cost subscription for everyone, and so you can kind of just go sign up for it, um but it kind of includes all those different things and uh I know there's lots of plans to add more um so hopefully that answers the question, but basically you know gives you a way to get rel and the sandbox um and, like I said, also customer portal access um so definitely go check it out. um So you know.

A

I'm just kind of looking at the comments um yeah, I'm looking at the comments too trying to find a link to where you can just get the rel instance like details.

B

A

B

uh It's there was a big announcement about it, but basically, oh actually what we talked.

A

About last week, which was.

B

Cloud.Redhat.Com um in here um you can actually I've actually never gone in this way. So let me see if I can figure out how to do it. um So there is this thing in here which is called subscription, watch, which why am I oh here it is. um You can actually go and see how you are consuming your subscriptions um and uh you know whatever. I don't have anything in this account or whatever um but long story short.

B

Those subscriptions should show up here uh and along with like insights, and you can kind of see your status um and then you can kind of look at you know killing off a subscription like so one of the things we talked about in the show last time was the problem, especially amongst developers or anybody who's like experimenting.

B

Is you spin up an instance of rel you attach a subscription to it? Then you ice.

A

Do some stuff yeah.

B

Detach the subscription right- um and so now one of your 16 is in use for some period until it times out, essentially right. um So what subscription watch lets you do is kind of like fix all that, but from uh you know, you don't have to still have the vm. You know all that stuff, so that's kind of the idea behind this tool chain and you can get to a bunch of these tools under cloud.redhat.com.

B

If you are not doing a live, show, it's a lot easier to read these words and therefore find this stuff, um but when I'm doing it live on the show I forget where different stuff is, but you can um manage, you can actually install openshift from here, like there's lots of different stuff. You can do here. I highly recommend it. It does a lot of nice stuff, uh red hat insights, which tells you kind of about uh your deployments.

B

You know- and so you can use this personally as well as use it like corp as a corporate account right, um and I think this is the kind of thing that it doesn't occur to people to use personally or like. As a you know, as an independent entity, you know for your own stuff, uh but it should scale down to you know kind of a regular user. It's not just for you know: 47 billion installs of rel yeah, so 7 billion huh yeah, that's a that's. A technical important number can.

A

You grab the link and drop it in.

B

Chat, oh sure, um I do like that. It's just cloud yeah cloud.

A

B

You know, typically, we would have to write red hat hybrid. You know enterprise advanced in front of it, um but this time we got away with just cloud. um Okay,.

A

So yeah keep going I'll answer the questions in chat. Just please.

B

Yeah yeah, um and so we go back to uh developer sandbox um and what I wanted to show was, um first and foremost, but.

A

B

Think kind of get to it uh is going to um uh what's called code ready workspaces, which is a derivative or like a it's. The product version of uh an upstream project called eclipse che um which, in from an experience perspective, is actually very very similar to visual studio code. So if you- um but it's kind of all, you know in the cloud, so your current code status is always there and now I'm completely blanking on how you get to it. um Did you go no, not.

A

B

A

B

To go, oh right, yeah.

A

uh Application view or whatever yeah so oh operator, hub's, not.

B

On here, oh right, okay, so this is one of the things that I wanted to talk about. So um let me digress for a minute. We'll talk about operators um often is the case is that operators are highly privileged to operate things, um and so, as a result, uh there's oh, which marin.

A

Duffy says: uh go back or just look at the the nine box thing next to the plus sign and question mark in the top right hand, side the nine box thing: oh nine boxes, the little box. Oh no,.

B

There we go, I was like, I know it's somewhere, really obvious I was just like. I cannot. You know, I can't think through it um there you go but yeah. Sorry all right. So let me just mention the operator's part, so usually they're, very privileged. The thing that I find a little confusing about the term operator is that you actually do have access to a bunch of operators, just not certain kinds of operators. um So if you go back like in here, um you can get or yeah. I don't know.

B

I I get a little confused about what we're going to call operator versus not operator or whatever. So like. You have some of these things here so like. If we say oh, so I guess it is missing the operators altogether. So that's where I think we're still struggling with like how to make a shared environment, be able to have this kind of newish feature to open shift of the operator. Operators are really nice because they have.

B

You know your uh sre experience embedded in the in the code base itself, so I can always just and we've done this before. Let me see if I can get it from the catalog, because it'll be prettier. No, um so if we go to the red hat marketplace container registry, something url.

B

If we go here, we can find things like mariadb, and so here is mariadb. 10.3 we've used this on the show before it has. It is a pre-built container um and we have a bunch of different uh versions for target uh deployment environments. um But what we can do is.

B

I'm just looking for the right link this one, but we might need to embed a secret. But right we can say like this.

B

And then just leave all that alone.

B

We will not create a route, um and so then we can kind of go, get a mariadb, I'm not sure if it will already have pre-configured the secrets to be able to log in to um the container catalog, um so it may fail, but we can fix that and it looks like it did fail um yeah. So uh we can fix that the same way we did in the past, but the point being is like you still have this whole catalog of content.

B

It's just that there's! This shift going on kind of moving from pure container images uh like this one, two um operators which kind of embed more functionality, so we can see, there's also I'm sure a bunch of maria come on really. Is this really going to fail me today.

B

Yeah, so, okay, so there's my sequel, I wonder: if we're going to get, I wonder if we got a different if we get a different result, if we tried operator hub dot, io.

B

um So here's the maria db operator- this is a oh. It's actually listed as alpha version is current, um so so this one's pretty early on, we may not want to use this one, quite yet uh without some expectation, but the idea being is that it keeps track of itself right and it will do as you can see here, it will do seamless upgrades of mariadb um it'll do full backups.

B

So all these operator things that you do to a database that you don't get if you just you, know kind of go after the container image, because the container image is just mariadb itself, so you can still seamlessly upgrade it. You can still seamlessly back it up and all those other things, but you have to write all that code or or put in all those operations.

B

So that's kind of uh the difference between like a container and an operator. The problem is that, with uh the shared deployment environment, um an operator is hard to uh set up. That was a lot of talking.

A

And the the question in chat is: what is that button actually called? It is, in theory, called the application launcher in openshift, but it is still considered a hamburger menu according to serena from the future. Oh this one yeah, the little nine box, dealio yeah.

B

uh That's interesting um see because I think this is a hamburger menu, because.

A

Right, it looks like hamburger, yeah and I'm gonna send her a screenshot and just say like arrow of that thing, just to make sure.

B

um You know if it was if it was truly fedora, though it would be a hot dog menu, um or we could really get esoteric and call it a sandwich um and then get everything.

A

We could call it a sandwich. Is a hot dog.

B

Sandwich is the question well or is a taco.

B

All right, so I don't know why I'm getting this in fact.

B

Because I have used this before so I'm not really sure what the deal is. um Maybe I was using a different account, which is certainly possible.

B

um The problem when you use accounts at your own workplace is you tend to have six of them, uh so, okay, so code ready workspaces um like I said this is like an online ide. I think it feels really similar to um visual studio code.

B

So if you like that um speaking of node.js, we can do a kind of pre-planned project in a sense, um and it's going to think about it for a minute uh and just keep in mind, you can go get code ready, workspaces uh yourself to deploy yourself um on your local environment. um I think, actually, while we're waiting for this to cook, we can look um oops.

B

I don't know: if is there a bundle download or do you always do it as an operator on crc.

A

uh I always do it as an operator.

B

Yeah, okay, you can also just download it um for like kind of directly, but basically that includes um crc. So what happens is crc is code ready containers which is kind of like a single laptop install of openshift, and so what it does is it kind of sets that up and then it puts code ready workspaces on top of it as an operator. So it should be the same exact experience, it's just kind of like how you get it um node.js, it probably apparently is bigger than a breadbox.

A

uh Who knew and narendra have just dropped in chat uh due to popular demands from the website, I'm assuming uh due to popular demand and repeated signups. We are increasing the free trial period to 30 days. So that's good to know. Thank you. Narendev appreciate that uh jp dade says there is an upper limit on the number of operators, name spaces you can install on one cluster. I have hit it and it is giving me a timeout when I do something. Okay,.

B

A

Instances aren't huge right.

B

A

You know typical, like six node, you know, hundreds of you know dozens of cpu kind of instances.

A

A

The okay, a lot of discussion about the icons and oh.

B

I made it angry because I got ahead of it: um oh boy, so yeah, okay, let me just delete mine, because that will collide. I kind of wondered why there was no files dropping in okay. So if you know anything about node.js, uh this is a pretty basic setup for node.js, um and so I kind of did a quick start right. So that'll give me like a base node.js application, but I believe we should see it already over here and we do here's my broken mariadb we'll just kill that.

B

But then we have now node.js that has been created over here um and assuming it has fully deployed. Theoretically, we can get to my terrible new getting started website. Oh no fail.

A

Such fail such fail.

B

It's also still digging.

A

Up answers to questions for folks, so if you're in the chat, just everyone's very chatty today, well they're asking they're asking very good questions that require research, you should just.

B

Know all the things at all times.

A

I know right uh but yeah the um the questions are great, so keep them coming. Thank you.

B

All right, so this should be working. I don't know why it's not working so yeah, it's doing here's a service port. It has a route.

B

Why doesn't it load.

B

Let's look at the logs logs are always.

B

B

Jp dade has his own uh level up our shirt. I wore mine last episode, I I think, or maybe it was one before that um I realized.

A

Before that I almost wore my eye today, but it was like further back in the rotation, the shirt blocker. It was like you know. Well, here's what I do it's it's kind of lame, but it's like uh you know. I have like my deprecated shirts or almost deprecated shirts.

B

A

Like I know which ones I need to throw out based on how far to the right, they are yeah, yeah yeah.

B

A

Work polos far right, yeah yeah.

B

I uh yeah it's tough when, uh like I had a really really good shirt um and then the company did some very bad things uh and I was like, but now I can't wear the shirt and so I stopped wearing it. It was very sad and unfortunate.

B

All right, so that seems loggy.

B

I really don't know what's going on like it really should be working.

B

I wonder if this has to do with our no, because the route should be going to whether we're in code or dev or anything else. It should still be working.

A

Okay, you go to the route, it's dead, okay, so what's not running behind it.

B

Yeah, it really just doesn't want to do its thing. um Go to.

A

Pod is running, go to the logs.

B

A

B

Yeah, this is where I was looking a minute ago.

A

It keeps changing ports starting with proxy starting reverse proxy, starting reverse proxy.

B

So this might, that might be an ojs thing. um It tends to listen on multiple ports, a lot of the time, um I'm just trying to look at how it's, but no it's just app.js, uh so it should be listening on port 3000.

B

um I wonder if this is a it's not listening to all um uh whatever you call interfaces so like if you're running this on localhost, um but that seems like a weird example choice. If that was true, uh anybody know js well enough to know off top of their head.

B

What's the thickets.

A

Oops, um thank you tomorrow.

A

Someone asked where to go: buy shirts.

B

Oh, oh yeah, yeah um yeah, apparently it's very hard to find. um So what.

A

B

Looking for oh listen, um node.js, listen on all interfaces, so this is a typical thing where it's like. Is it sc linux, or is it a firewall or is it uh you know you're not listening to all uh tcp yeah? So this is what I was wondering um if you don't specify the host we'll run on all interfaces? Okay, so um so it should be listing on all interfaces.

B

um That's what I was concerned about, I couldn't remember if node.js some of the languages default to only listening to localhost and some default to listening to everything- um and I couldn't remember which one node.js was, and so it is listening theoretically on all interfaces, um so that should be right.

B

um Let's just see what are all these containers.

A

B

A

At these containers.

B

Oh, I wonder if it's angry, because I was experimenting with something else in here: oh yeah, you might be, um that could be it or if I did it, let's go where I know I've never built anything so we'll do a different project and see if.

B

B

Wow we're we're batting a thousand today, oh yeah,.

A

So I can write that out what.

B

Happens if you hit start debugging.

A

I have no idea.

B

All right so because.

A

There was no choice, it's slowing down, so let's think about this. How did you.

B

Deploy it well, that's the thing is I don't know, because if I go to code ready workspaces here, it's am I which project am I in.

A

Well, that's the part, that's what I'm trying to figure out like where's your stuff, yeah.

A

Okay, so is that a project in workspaces or.

B

Is that a project? I think this is a project in workspaces, okay, um and so does.

A

It tie to it. Oh here we go london code yeah. There.

B

A

B

Then so how do I make one in a different one? I wonder.

A

In a different name,.

B

A

A

Say a different name: space somewhere. Oh it's under code, says martin, it's under code. It's under code.

A

B

I didn't know mo news so much about uh code ready workspaces. She clearly knows more than us.

B

um And uh the worst part is I've actually played with this before and had much.

A

Better luck, you would. The inv is under the code name and the open shift. Ui.

A

B

A

So urine there it is.

A

Says it's running and.

B

A

B

What this does? No I'm curious. Oh, not not the kind of private cloud I was thinking of um all right. So that's wrong. I wonder if I can just kind of change the ammo.

A

Or just start a new one in the right place, maybe.

B

Yeah apparently.

A

B

Mo thought we were in the right place, but now I'm not seeing all right. We can do registries, so apparently uh we should have had we. We were gonna, try and get a guest this show, um but then we were like yeah, we'll figure it out. um So uh yeah apparently.

A

Apparently, we needed a guest, um so if you so it's running in a workspace and that workspace is tied to a openshift project right.

B

Right so that part seems correct: okay,.

A

You're in the lane in codespace container, creating.

B

Yep because I just restarted it, um which oops, which seems correct, um I just don't. I can't quite figure out how to tell code ready workspaces to switch to using a different um open shift, namespace or openshift project project. Okay,.

A

So ah crap, let me look and this seems.

B

Like something.

A

I should be able to figure out so if you go into administration there on the left, this one yeah all right, you can only add a registry. Okay.

A

Then workspaces.

A

You should have two because you created two things. I don't know why that is, but whatever.

B

Still thinking about it.

A

Yeah I'm trying to get code ready up on my thing. You just deployed a node express app.

A

What do you? What did you deploy project wise.

B

Oh yeah, no, it was a node.js uh express starter project.

A

A

So I'm wondering if so, I'm in c short dev.

A

Where does this end up.

A

This ends up in seashore code, okay,.

A

If I get a it works on my machine, I'm just going to switch cameras.

B

Exactly that seems correct to me.

A

Chat here this is high quality, says someone okay mo says there is add project and code ready workspaces, but that's to add a git.

A

Repo, yes, code, ready workspaces are bound under projects with those projects.

A

So moh says, project and open shift appears to be namespace and code ready, workspaces, okay, interesting.

A

I think the crw ide instance is bound to the openshift project itself. I.E. Your crw thing is in langdon code already. That makes sense, because it's.

B

Right already right, and so so.

A

B

Promotion kind of activity right.

A

Because the idea is.

B

Is you know, code dev stage? I think that takes place in open shift lane.

A

So the default app does not, I mean yes, it creates a route, but there's nothing there. The application is not available for me as well. So.

B

A

Put something that would make it display a page or something yet probably not.

B

Well, this should be showing uh a default like at slash.

A

B

Saying hello, world yeah, okay,.

A

Let's make sure the route points to what.

B

So the route I think points the service service.

A

Yes, the node.js service, which is running on server 3000, the server yep okay, um pod selector. I don't need that labels don't matter. Let's look at the ammo real, quick.

B

And is there a pod, that's actually doing something.

A

Yeah, like that's what I'm trying to figure out right like so serious, it's great that it's a service and it's up and running, and it's supposed to be http right, which it is because it is responding. It's just responding with a 404, essentially.

A

So I think you trying to switch anything like project and namespace and workspace and all that stuff, like.

B

A

In code, like that's just where it starts right, right right, w starts in the code name space, which makes sense, because all of your coders would live in the code project right.

B

Right right, that's what I was kind of saying is, like I think the deployment or like the promotion activity is something that takes place in the open shift side, not in the workspaces side, which makes sense to me, um but I feel like we should be able to access.

B

I'm gonna look at the pod real, quick this one anyway, um you know because the route is pointing at the service.

B

But it just doesn't like it and I'm not sure.

A

A

Ps, even on this box, nope, never mind or pod, I say box, even though it's a container yeah. I can't get past that it's still a box in theory, but like it's like certain, don't say container, I just say box right like just like, I would say, vm right right, it's weird!

A

uh That's that no nothing! What do you got for me.

B

It really, it does seem like it should be working. I don't really know what the deal is. um Clearly, the the thing I prepped to do was not this, um and uh so maybe I don't know if we should go play with that. So.

A

Conan kudo does point out that we do have a bunch of vs code extensions and one of them is for openshift. So if you were in your ide outside of this box, you could you know, use that connector to connect to this instance and use your ide for everything that we're doing. um Oh.

B

Yeah, um I don't know if I have the extension installed.

A

Ooh nl hackum says it's not specifying the port in the url. No, it's not because the route points.

B

A

The service right so that route is saying: hey service, you're running on 3000 great. I don't care it's just going to create a link into that service, whatever port it's pointing on, so the routes are a little bit more than the ingress like they have a little bit more knowledge.

A

So if you point her out to a service and the service is actively running and working, it should just work like hello. World should show up, but it's not for some reason.

A

B

Mean we could try it, but I don't think yeah. I think it should just work. I.

A

Thought who knew so? Let me just.

B

Get to the face.

A

Back to my topology, okay.

B

A

It's fully thinking and spun up.

B

All right that looks like it's doing a straight up timeout rather than um like. This is an application error. uh This looks like it's getting a straight timeout. That's why it's taking so long.

A

Okay, so maybe you need to blow yours away start a new, maybe like it didn't, deploy correctly or something.

B

I yeah, I think I tried that already I mean I didn't try like killing the entire project, um but I did try uh rebuilding the pod.

B

Oops, so if you go here.

B

A

Do we, you know we could always try a different thing too.

B

Well, that's what I was gonna say was. um I did. I was gonna talk about hoogan there.

B

But I was gonna see if uh you know kind of try this one last thing, um but apparently we're gonna need another episode about the sandbox, where uh we spend some more time messing with.

B

It I know how to get kind of in general, um you know stuff working in openshift, um I think, uh and I've even used code ready workspaces for it before I'm, not really sure why I'm having so much trouble. I think it's just I don't know something stupid.

A

I think it's just they're, like the environments you used to working in playing then are like aws. You know right large, like you know, rhpds, maybe right where there's tons of capabilities and you can just find stuff super easy, because you're like directly logged in there is an abstraction here that we don't necessarily know about right.

B

Yeah, I kind of wonder if it's yeah, if it's that, although I I still go back to the it- is highly likely that I'm an idiot and missing something really obvious. um That is entirely possible too. So I, it could also be. It seems like maybe in the chat some other people have been trying it and um maybe errors. Okay,.

A

B

Maybe node is what's busted, I wonder if we could.

A

Try run this attach to remote.

B

A

The problem I'm actually going to do the debug it says attach the remote is running.

A

Refresh on this page nope, four, four, okay, that sucks oh, can I connect runtime process timeout, ten thousand milliseconds.

A

That's connection refused error, interesting, okay, so this might have been the wrong thing to use. If you notice, your workspace has an error top line.

B

So maybe it was just this.

A

Particular thing which kind of things.

B

Yeah I hate that.

A

The app.js file should just be hello, world.

B

A

Okay, so that's a like thing: we need to go back to the team with and be like hey. This doesn't do what it says. It's supposed to do, right out of the box right.

B

Right, um so what if we so? What I'm not sure of is how do.

A

I help like pulling a helm chart for something, or you know something crazy like that.

B

And this one doesn't want to, let me delete it because it's just because it's running um yeah, so I was going to try to, but I wanted to kind of get the.

A

B

Some of the stuff out of the way.

A

Just add another workspace, pull it in. You know.

B

All right so add workspace. No, we don't want to do it that way. We want to do it. Yeah. That's.

A

B

Like go to the product.

A

B

I don't know python, or did you say, did you have something in mind like go.

A

Back to uh openshift itself and do an ad write a book yeah and like just pulling a helm, chart somewhere or operator backed you know anything.

B

Let's see, do we see any cool home charts in here quercus.

A

uh Here's another node.js.

B

One um try the quarkus one, all right. Let's try quarkus. I.

A

Don't think I've ever written like read the well, never mind I was going to say, read the documentation. First, what.

B

Have you met me.

A

So you need a pull secret right.

B

Oh prerequisite.

A

So this is not like a great thing for us to try out.

B

Yeah yeah, um that's I mean it's a little bit of the problem with the uh oh look. Node.Js, though, does not require anything okay, um so.

A

B

Right, I'm trying to.

A

Do something in python smile says.

B

All right, let's do let's try it this way and see if it was purely the node.js one that was angry yeah. um Let's make sure.

B

This is our new python one right.

A

B

A

B

Jp dave says you know.

A

They have the nicotine patches, they need to invent a caffeine patch agreed. I'm.

B

Sure there is one somewhere there. Oh I mean isn't that what like nodoz is well.

A

Yeah kind of, but that's like well, it is just a caffeine pill. Yeah. um I like the coffee, though moe says so in code, ready workspaces on the right hand. Panel there's the 3d cube icon, you click on run web app and you get the errors. Okay, good point um cannot find express module.

B

Yeah, like there's.

A

Something wrong with that setup: dealio.

A

B

Jp david says: rtfm.

A

B

That's that's how you can tell that. I think jp dave comes from an administrator background right, whereas I come from a developer background, where it's just like yeah.

A

Whatever wig it so just you know, for everybody's awareness, rtfm is kind of being considered a you know, not inclusive term anymore. um It was ever.

B

No, it was never an intensive term.

A

Like because, let's face it right, like open the man page for get on three, oh.

B

A

You meant this probably different well that yeah, but like I'm talking about the actual manuals.

B

Oh again, like yeah.

A

Either a there's so many different manuals, you don't know which version to pick from or b the manual is your documentation, which is probably not up to date. So, like.

B

Although I think I one of the things that was really interesting, that came up in the subscription show last time was the suggestion that, if you ever want to go, take one of the certifications um don't study for it using web browsers study for it, using like man pages um and basically only things you can get to from the command line right, which that would you.

A

I don't know that that would have occurred to me, but I thought that was a really.

B

Brilliant recommendation.

A

All of our courses- I you know like when I have ever taken a red hat exam. I have always said here's my vm here, like I tried to recreate the you know, quote classroom environment that we would have so like it would be like a vm with just the packages installed that would be installed on the node in the classroom.

A

Obviously you have to know that, but like for ansible, it's really simple. It's just ansible and you have docs and man pages for ansible that are available to you, including a full html version. If you go look and find it at the right place, you can pull that up and click around and you're good.

A

All right so helloworld.pie, if you run it, what happens hello world? That's good! Now,.

B

This is an open shift.

A

B

This is right, just a print your like is it gonna, make it route like what.

A

Is this gonna do click on it and it's a pod it has. Does it have a service we can make a route for it.

B

A

Because there's nothing.

B

Listening there's no web server here.

A

Well, go back what were all those services, then it it.

B

Like the project created the service- oh no, these are the node.js. No are these the node.js.

A

Yes, some of the same wt proxy, like.

B

Oh, no, you know what this is a route to that. No, these are or I I think these are the uh uh code ready workspaces services to do loop, backing on debugging.

A

Oh, that would make sense, so it's actually running the stuff. That's in here.

B

Right so question is.

A

Can you make a new service and then point a route to it.

B

But there's there's no server to go to is the problem right, that's what we have to get to right, like no, no, no like like there's no python is not listening on any port or anything else. It's literally.

A

I don't know, I know oh right, like you'd, have to drop in like a code snippet or something for like you know,.

B

Right right as.

A

Http onport whatever and then create that service and then point her out to that service, and hopefully it works.

B

All right uh we'll get a conan kudo to type something in the command line. That will give me a quick and easy uh web server.

A

uh Python web server.

B

Like I probably could here we go, is this microsoft? Oh god, I thought that was what would have been.

A

Where it was oh, we landed on the same page. Look at that. um Oh right, we could do.

B

A

3-M http.server or python m dash simple http server.

B

But it's got to be.

A

It would have to be another pod right.

B

Or we'd have to do it like what we want to do is kind of I mean we could shell execute to python. um We also need to do it to um so. What is it import there we go. I think I was like.

A

So yeah like are you pulling in flask or something? Maybe I don't know.

B

B

And then I think it's like, uh let's see.

A

Universe, unite.

B

As we uh talked about with dan walsh, uh nobody ever actually writes any code. uh This is what I was looking for there you.

A

B

B

This should work. Let's make this uh just.

A

The only nine thousand point- yeah yeah just remember the port number.

B

Yeah, I just want to make sure it's like nice and non kaleidy.

A

B

um All right, so that should work, and let's say I wonder if I never clicked start without debugging. I wonder if it was somehow like not running or something right.

A

Well, it would have been an error somewhere that we would have seen in openshift.

B

So it just queried me over here um on.

A

Redirect is now enabled external url is.

B

A

Go ahead open it that you're ridiculous come on there. It is folks kinda kinda. No, that's not the python app at all. That's a direct.

B

Yeah, that's that's literally the directory uh all right.

A

B

Is listening? Okay,.

A

Theoretically,.

B

I'm port nine thousand.

A

So that part, we should.

B

Be able to fix.

A

Back if it made a route, no, so we're not gonna make a route. We have to make the route ourselves.

B

I thought what I was agreeing to in code ready workspaces there was to for it to make a route.

A

Go back out scroll up on the right hand, side there, scroll.

B

A

uh Hit actions.

B

Yeah and then it's.

A

Not add health check almost not in there, okay, cool.

B

It's somewhere, I was looking at this the other day. um I I think I actually filed a bug about this, um that there should be an ad route here and there isn't.

A

Well, you have to have a service first, I think that's serving probably hello world, so you need to go in and say is.

B

There, an interview you have to go into admin.

A

At a service it would be under workloads.

B

A

Sir yeah, there you go never mind.

B

And so create whoa. I don't want to do that. I want to shut her out. Let's see what happens. Okay,.

A

B

Try python http um and no path, no pass.

B

And I think you can do oh fail. I totally thought you.

A

Could you have to create a service? First, you were right. I.

B

Thought we could do it, so what you have to do is.

A

Say like just do all this, this is fine. You know.

B

Wait no, this is, this, is external right and.

A

Then this section this is internal yeah, so your 9000 goes there I mean if you want to name it something other than example. You know whatever.

A

Oh wait. No, uh you need something from vs or not vs code code, ready workspaces.

B

But what's the selector going to be go.

A

B

Have another tab.

A

With the dev view, yes, I was going to do it again.

B

Oh there it goes. I thought it was just blank white, but there is a little like feeling happening there.

B

B

A

ah That's just the name: there's the pod selectors right there, so I would think it'd be one of those, but maybe not no, definitely not that, because that's the code ready workspace part this.

B

A

Weird no offense to everybody. That's worked on this. This is weird.

A

Resources, so if there's we're creating a service, this is to the go to the yaml. Yes, all right, so annotations, scroll down is this. No. This is the workspace. Crap still never mind. I want to see the pod stuff right, like the the actual working.

A

Right because I mean we see it here, right right, but it's running the crw, not necessarily an open shift.

B

Right, so is there.

A

Is it being exposed? Somehow I don't know, that's.

B

Kind of weird like do you is there like, I was thinking there would be like a deploy button.

A

Maybe I don't know, I don't know enough about code ready workspaces to be honest with you.

B

Yeah, I totally thought I had done this before, but.

A

Maybe I I might have only used it local.

B

Like on, like podman, rather than through openshift, okay,.

A

So we do need to get a crw expert on the.

B

Show, I think so I think so I think we're gonna. We should uh probably call it a day because we have done you.

A

Got points to do buddy.

B

Yeah um and uh we're already.

A

Finished on a high note points.

B

A

B

Exactly um sorry trying to find the right window.

B

So well, you know, actually one of the things I wanted to bring up is give.

A

B

A

B

Was we have had a lot of guests on the show lately, um and you know, do we like having lots of guests, or do we also want to do more of this craziness? Normally we do a better job. I think of we should have a feedback form for the show we could have. In fact, we do it's on github, um where you can file issues.

A

B

We should do a separate form, so jp david says we should definitely have a crw expert.

A

uh Did you expose it? No, uh no.

B

So I don't, but like the there's no like running, we couldn't find a running pod of the code. So we think that the pod is like running over in sorry, the container at least right is running over in crw, and I don't think we told crw to push the container into openshift even.

A

What the real question is is jp date, a crw expert, and could we just bring him on right exactly exactly.

B

uh Detective coda kudo uh points out that he.

A

Likes to see langdon.

B

In particular, fail at things well, he said, and chris short, yes, yes, um and uh especially uh where I am about it uh yeah and he feels better about being bad at openshift. Usually I'm a little bit better.

A

You must be off game today or something man yeah I mean I have an excuse. uh I burned the out of myself, sorry for my language. I've like burned the bejesus out of myself, literally right before the show making coffee so.

B

A

Yeah, I could not prep, because I was tending to wounds uh and jp date is not a crw expert, so we'll find our own all.

B

Right, well, we will, we will revisit this and do a better job uh next time I really thought I was gonna have I because I had actually prepped uh with this project called huggin or hoogan? I think is how you say it um which is like if this, then that uh for that you can kind of deploy yourself, and I thought the only problem I was running into was um basically manipulating a database, but I think it was actually way worse than that. So.

A

Looking at looking at the template, you deployed yeah.

B

Yeah well- and I I think the other thing is like um one of the real values of developer. Sandbox is actually getting code, ready workspaces, and I didn't really think about that until we started talking about it on the show- and I have not done a whole lot of experimentation. Jpd.

A

Says you got it running somehow um so feel free to uh see.

B

A

Show us in an issue or pr or something.

B

A

Like if you want a prn, how you did it just like, like literally five bullet lists or whatever yeah.

B

A

Points anyways points.

B

So, as kind of expected uh neurodev, you know up another 100 points. uh Netherlands, hack up another 100 points. uh No friction, I think also up another 100 points uh I think joe fuzz did not do um the last show. I think it was somebody somebody did not go up, uh which I was a little surprised by um detective. Kona kudo had a big jump because he hit one of the risers um and uh I just sorry shout out jp dade uh yeah. I also love visual studio code. I think it's a really good idea.

B

I really expect to see it to be the winner um and then bacon fork, who I just saw uh tell me that I should go. Make another pot of coffee, which I.

A

I completely agree with.

B

Is also still definitely the running, so you should get your I guess escalator is, is a good word for it, a riser if you come from like a sales background, um but basically, if you, if you hit a certain number of episodes, you get bonus, points is basically boils down to. So, if you want today's points, um I just put the links in the in the chat, um thank you and through the magic of restream we should be getting uh getting those to go across um and I don't know let's uh wow.

A

It's been a while, since.

B

We failed so nicely on the show, so it brings us back to our roots, um but.

A

Yeah we had actually had to have a persistent volume, a persistent volume claim and put in a separate namespace, and it started working.

B

Oh weird yeah, like.

A

I said I I still think I figured that out.

B

I'm clicking some button, I'm not clicking some stupid button that is uh anyway, making it not work, we'll debug that.

A

B

That cleaned up exactly.

A

We'll bring on a crw expert to teach us a little bit more about it. How about that.

B

Well and- and I think one of the things um would be important, is you know if anybody else on the show or anybody in the audience can experiment with it as well? um I think it'd be really great to give some feedback to the crw folks, because I know they don't get a whole lot.

B

You know, and so, if we can kind of tell them our experience with it, that kind of thing we can, uh you know, make the product better. So that's our show.

A

Yeah, thank you. Everybody. We.

B

A
