From YouTube: Knative Community Meetup # 1

Description

The Knative Community meetup is a virtual event designed for end users, a space for our community to meet, get to know each other, and learn about uses and applications of Knative. Every meeting has a 30 minutes demo, with allocated time to discuss this in small groups.

In this first event, the demo was designed and run by Joana Saladas, software engineer at IBM.

Meeting notes: https://docs.google.com/document/d/1o0ENlHpv5nYPOznlbDc9xzNcwTqtxZrmPAVZLoWRHyE/edit#

A

The chat, if you don't have it please add a comment on the chat on the side and somebody will send you a link I wanted to announce that we are recording the meeting, as we usually do with our working group meetings. Four key native and these recording would later on and be available on the Canadian use of channel.

A

So without any further ado, let's dive into the first topic, which is the Till's, the election announcement I think Brenda Chang is talking.

B

About that, hey everyone, I'm Brenda I'm, representing VMware in the canid of steering committee, I- think a bunch of you know that we've been putting together our process for our first TLC election.

B

So I sent it an email earlier this week to the key need of dev mailing list for people to submit their nominations, for who could be nominated for the next TOC. So everyone is eligible who are currently on the TLC and approvers with at least three months 10 year, people can self nominate or nominate other people. So if you want to nominate someone just send an email to the Kane Kay native steering committee, google group email address by the 23rd and then we're going to start opening up our election.

B

So if you have any questions, feel free to reach out on the K native slack, we hang out in TOC steering questions. I think it is, but anywhere in general is trying we'll make sure we can. That answer your question.

A

Cool, thank you very much and we are going to move on to announcements by working groups and the first one is even thing with Alexander's Lewinsky.

C

Yeah I hope you can hear me. This is just a very quick announcement that we are looking for people that are using an IT s, Nats streaming into native eventing.

C

We are looking in particular for maintenance of it if you are using it and you would like a native eventing to keep supporting it. It's very good. Let us know there is a github issue. You can find it in this Google Doc in notes and come, and you know make sure we know how you are using it and we make sure it will be supported in future.

C

Davi. Do you want to say something about it? Yeah.

D

Just just quickly, this is Davey Odom from sa P we've had some people step up from the Nats community B already who are interested in taking over, but I think you know having more people involved, as always better and as a former maintainer x' were happy to help facilitate handover and and help the process along.

C

That's all and, of course, come to creative users, and you know let us know how we are using eventing, not just for not streaming check in our truck channel eventing. That's all thank you.

A

Thank you, Alec um Nick. Next up is networking. Networking working group.

E

Study updates, so the first update is Collier is new ingress that supports Kennedy and the difference main difference with sto control, blue and get skunk. The worldís report is that Korea was specifically written for Canadians, and it's also really lightweight compared to mr. ambassador doesn't require any specifics. You are so that's something you can try today.

E

Similarly, there's a new, if you don't want to set manager which is pretty heavyweight for other TLS and let's encrypt to get certificate for your energy service automatically, there is a new HTTP one solvers, which does just that part something the challenge for its encrypt.

E

The third one is something very important if you use any of the east, your tooling, so today the tooling shows you the flows between services in your mesh and matrix errors, etc. But it's cope by service and the premise connective is we create one community service per revision, so those tubes were not very useful for Kennedy, because you will get one prohibition and would we wouldn't not show you a good overall you and now basically miss the tagging feature.

E

You can group services into the same overall service and it shows up as one clean service in the UI. So that's what this canonical service feature does. And finally, this is a big one, so initio a 1.5. We fix all the issues in Canada working with the SEO team. Where now is you got mg/l a strict?

E

So what this means is before we were supporting MPLS permissive, where you could permissive means you can connect through plain text or TLS and strict mode and forces all the flows within the mesh to be TLS, so that the big change.

A

Thank you. Next up is Vincent with operations working group.

F

Yes hi: this is a person's working with operation work group. Here's some of the key points huh as the information I would have to deliver.

F

First, we have that's a official installation guide for operator as well, which has been released along with serpents 13 way, so keep on doing that for short for 14 and second one, since the operation will be, they choose all source for us to config serving an event in here. So what I documented as a guideline for see us on how to configure our serving an event ends with those operator see ours is still under review at this moment are likely encourage people who are in Germany in insult relation with operator.

F

Please take a look at this PR and you will find all the capabilities we can't do as a similar moment regarding at the operator, CRS and I also plan to make it available under the repository as well and for 14. I know that for no key component, like a serving and even it has already released a few days ago, operator usually has like a few days what one week time bar for us to sync up and we'll cut our release a man early next week and for the 14 it was been.

F

Such a milestone for operation is due to that. We have a will post release the two operators separately and we also release a all equal operator since always set up the Republic for the integration under sandbox, as normal will release one integrated operator, fortunately under that one so with the 14 kaiser installed separately or installion. 1 & 4, which will in terms of serving component, will contain only support a co as the ingress for the next release.

F

We're talking to have support of modern aggressive may be able to config was the operator CR, so that can pick up difference and ingress folks alike, so yeah. That's all for me. Thank you.

A

Thank You Vincent, the last update, is from the client working group from roland is up yep.

G

Hello, so my name is Roland who's, I'm from from reddit and I'm, one of the working group news for client and yeah first, a quick overview. What Barry stand with a KN client so cane is a Scylla tool which you can use to interactively, create a native serving and inventing objects, so the serving support is quite complete. Actually, we have all corporations for services and you can in inspect services. As you like directly from the CLI.

G

We have support for traffic, split that you can interactively and declare your preference bits and as well at the auto scale, parameters and, finally, quite newest in export for services to actually you can to interactively and incrementally build up your services on the command line and then finally export those services into a machine readable form it like llamado Jason. So this can all be done for Kenneth Irving. We have also basic support for native anything.

G

So actually we have good support for all the not but for most of the business sources which gravy venting comes with like the pink sauce, the API server source or sink finding. The support for the container sauce, which is new in creatives eventing on 14. There are back again, let's say like this: it's already in the works, so this will, you can expect soon and one of the next to these is 4k and, and we support support for management for Twitter's.

G

Then a new thing is that we in the that used a new get up repository. It's called client contrib and this client contra is supposed to, or is it has been added used for, holding all created extensions, so the client like a plugin, so KN itself has a kind of a plugin architecture.

G

Much like you control itself and so inclined quantity will host the black and search we are going to support so feel free to have a look there as well and but we're just starting up there. So it's just poor requests which are pending, but you will see soon they're, more content and then finally yeah you can try out decay in client with quite a lot directly or you can use also boo if your neck onus directly and started directly with a known tip from Canada, so I paste it here, they're installation command and yeah.

G

Finally, actually we also look others for computers for sure, like and like any other project as well, but we also are looking quite quite eager leave for feedback, especially UX related, because so whether we are really if a kind of a could you use experience like are the comments and to intuitive other comments are consistent. Are the options naming are good?

G

All of these, let's say soft things really very important to us and the more feedback we get the more opinions we have there, the better, and so, if you have any any opinions on that, please feel free to reach out on slack that was their Cecelia channel or open trust issue and the creative client repository thanks. That's funny.

A

Thank you so much Roland.

A

And now we are going to move on to the demo. Part of the meeting Jonah is going to present I think to everyone now tracking the Bitcoin ledger so Joanna whenever you're ready.

H

I'll share my screen. I think you can see it.

H

If you don't see my screen, I should carry out with that. I live in the middle of nowhere, so the Internet's not always great happen. Can everyone see this? Yes,.

C

H

Thanks for letting me share, I said last week to everyone that we've never done a presentation before. So, if you, if you really don't like it, let me know, but maybe not on here um so I joined the world of cloud native about six months ago. I work for IBM as a software, and you know I before that. I actually had done nothing with cloud native before I was got a background in data engineering, so very different. Sort of world and I wanted to try out K native inventing, because I looked quite cool.

H

um So this was like my first experiment with with K native eventing, so the demo is basically just really simple: there's a sauce which is a Bitcoin web socket.

H

Then the messages are sent and these messages are then displayed in real time consumed and displayed in real time via a UI.

H

It highlight I wanted to highlight, like K native eventing in a quite simple ways, there was just a broker a trigger or a couple of triggers, depending on which one you're deploying and then a producer in a consumer, and there are actually maybe two or three consumers.

H

It buzzing is because there's a loss in the room next to me, which is a bit creepy and issued as they show streaming. Events in real time in stream, transformations and push-based front ends.

H

So I used a Bitcoin transaction data because actually it's it's a real rich data stream. That's free, there's also fin hub to IO, which is a good one for financial data that you could use instead, I think you know you can use Twitter, but it's pretty overused and I think this is like quite a nice alternative for companies that maybe work in finance or insurance. Things like that.

H

Just like some ideas of what you could do with this data set. I think you could like predict. Transaction fees visualize the data. So this this link is actually selling you a Bitcoin wallet which I'm not promoting in any way, but they have a really cool visualization on their website, probably not done through inventing, but it's all really cool and you could set up some classification for transactions and send push-based alerts and things that which I actually will show like a classification method later.

H

So you need some stuff before you deploy this. This is the stuff you need. The code can be found on my repo on the following repo. So the first one is this scenario that I'm gonna show today and Kay native Bitcoin WebSocket event source is just the WebSocket source for the Bitcoin data, which is also available. I've got a blog, which probably is a bit lower level than anyone here would need to read, but it's just like an introduction into things like eventing. While you do have been doing things like that, I think.

D

We're still seeing the first slide. Oh really,.

H

D

B

H

It mean, is it back again, it's.

B

On part, three okay.

H

Anyway, okay, um let me know if it hangs like hangs I might need to do a bit of jumping around and so I wanted to like for me. I wanted to see like. Why would I actually do this like? Why would I do eventing as a business or you know? What are the advantages for me, especially someone who does not know it was not really technical, there's other ways of doing some other stuff I mean there's other ways of doing exactly what I'm about to show you.

H

So I really wanted to highlight some key advantages, and these were just some of them. I think a native eventing really lends itself to push based messages. Messaging, I, think there's real true decoupling of producers and consumers and I think it can be really useful if you want to do things like for detection.

H

Also, some ml op stuff, like the rendezvous architecture, I, have not implemented yet, but it's something that would look out.

H

Can you see this slide.

A

We can see this by Y, then driven yeah.

I

We're still hungry yeah.

H

J

I hadn't wiggled between.

H

Which is a web web? A web socket that's supplied by by a block chain info. We've got an events all seeing the messages, turning them into cloud vents and then sending them to the broker, and then we've got an event display which is subscribe to these events that come from the blockchain source and it's updating a UI front-end in real time so show you. Can you see my terminal.

A

Yes, yes, okay,.

H

So I'm just gonna apply.

H

Create a namespace and eventing in that namespace.

D

There is some in a little bit in terminal. Please sorry.

H

I

You can zoom.

J

In a little bit,.

H

B

H

That was not that one shoe that.

H

That a bit better.

H

um Yeah so then I'm gonna just deploy the websocket sauce. If you want to build it yourself, there's already a docker image. But if you wanted to build it yourself, all the stuff is in the repo see and do that.

H

I'm not gonna, verify the events now, but you in the next slide. There's some commands that you can use to verify. I'm then gonna deploy it trigger, which is going to say that I want to subscribe a service that I have not deployed. Yet to these events and then I'm gonna deploy my UI service, which takes the messages and displays them on a UI which probably in a real microphone. So it should be two separate services but they're one at the moment, and there are kubernetes deployment.

H

So there's two yeah more files that I deploy one for the deployment and one for the service.

H

And then, if I go to my my with my UI site, where it's been sent to, you can see their messages isn't true in real time, and this is done with a server sent events library and go I'm. Gonna flip back I'm just gonna delete the these two services because I'm gonna deploy another one and my computer died. If, if I leave everything running, fortunately,.

H

Okay, so that's the first part in its most simplest form. I. It uses these deployments of both kubernetes native deployments, they're, not a native serving deployments. These are some useful commands.

H

That you can use to deploy to you the the what you've got going on and to verify the messages.

H

And I wanted to talk a bit about the WebSocket source that I'm using so like I said you could swap it out for something else. I would like to add this in in the future. I haven't done that yet but baby, and this is like just a deep dive on the code for the WebSocket source, um so import venting and WebSocket client, so um using the guerrilla WebSocket. One I should also caveat that this was also the first time that I've ever go so there might be better ones.

H

Use I define the WebSocket source URL, so this is actually for the web, socket library, not the cloud native source, although I do use it there as well. I read the syncing from config, which is pushed from the amyl file that I deploy into the deployment.

H

If you want to get so I reference, the broker URL, as my sync, if you want to get the broker URL, if you don't know what it is, this is the command to do it, and then it will give you your your broker address.

H

Can you see the next part of the code or do I need to shuffle again shuffle again anyway, so the next part I pass the config and Virant variables we a cloud event sync, and then we set up a cloud event: client using HTTP transport.

H

Then we connect to the WebSocket that the URL that we specified earlier, which is the blockchain info, not changed. Our info requires that you send it this message: Oh unconfirmed sub, to initiate the transaction stream. So we do that and then we read each transaction message on the way, create a new cloud event for each message. In this case, I set the type as WebSocket event.

H

The source is set to the the address that we gave as our WebSocket source, and the message is the message of the transaction, which is going to be sent on there's like a que native official web socket, which you can probably play with as well, and get it to do. A similar thing. I guess, like I said this is just sort of how I approached creating it. I found it quite hard actually to find in the docs like what I needed to do.

H

It was a little bit like unclear for someone that's completely new, but but it was ok. um So the next part that I wanted to show is this sort of scenario and your.

I

Screen share is still stuck at the keynote slide. 9 I think 9.

H

Ok is this okay,.

H

That should be on slide 11 now.

A

Maybe try turning off your video I think it's gonna make it easier on the connection yeah and we can still see like nine but on the edit mode of the presentation. So not the presentation mode of presentation can.

H

You see this now.

A

We are seeing the presentation- yes.

I

We see part two classify and report.

H

This part working as well, so this was slightly like a slightly more I guess: Bill our example of what you could do, so we have our container source and our broker and the event display that we deployed in the first part. But this time we also have a classification service which is going to take the transactions and it's just going to classify them into a size.

H

So it's gonna just classify them as small or large like very simple, and then it's gonna send that size classification back out as another message as another event back into the que native presenting ecosystem, and that message will then be consumed by another service, and the idea is that this could be something like doing like some sort of transaction in the fly and then maybe the other service needs to know. Okay, these these transactions are really large. I need to alert someone about this.

H

That kind of business use case, so I'll show that one as well. Can you see my terminal screen.

A

H

A

H

It might just take a while to sort of catch up with where I am.

K

Think of it as sous-vide.

A

Is it I want I wonder if it's on a different screen.

B

A

Joe, if the, if the terminal is on a different screen on your laptop.

H

K

Anyway, it's still showing the slide deck yeah.

H

Not really sure why cuz I've sort of shared my screen so that there's a bit Oh.

H

Seems like maybe it's just having trouble catching up with where, where I am I, could try and stop sharing and re sharing again and maybe you're like okay.

F

H

Yeah: let's try that.

H

Can you see at our little screen.

A

A

Can see it, can anyone else see it I.

K

Only see Jose static, profile picture, yeah.

A

I think it failed to proceed. It says presentation that it doesn't show anything that.

H

Strange yeah, weird cuz, it says you are presenting to everyone in my screen. um Okay, I can just talk through like the last bit, I mean the repo is there. So if it comes up just let me know and then I can deploy while I'm talking it.

I

Looks to me like it might be, prompting you for which screen you want to share, maybe hidden under your main window, or something like that. I've had that happen to me with hangouts before let.

H

Me have a look, so it says you are presenting and then there.

I

We go now, we got it. You've.

H

Got, can you see this well.

G

I

G

You are presenting so I think we're seeing the same thing. You are yes,.

H

Strange because I'm just on the same screen, so it seems like it's just playing catch up a bit actually I'm, not really sure why. Maybe it's just really slow I'm, just trying to get rid of some of this yeah so um that this seems to not really wanna, says I'm presenting to everyone with my terminal screen.

F

H

Nagin's, okay,.

J

H

um Okay, so that this makes it seem much more exciting than it really is, but now, let's just do it anyway, so we've got the source running I, don't have any other I, don't know any other services running at the moment. So I've got another folder classification, and in here I've got some yeah muls I'm gonna apply the.

H

The another trigger which is basically the same as the trigger we had originally, but it's just subscribe to a new service which is going to be my classifier service. So now I'm going to deploy my classifier service.

H

And I'm also going to apply another trigger, which is basically gonna, be subscribe to by just a simple event display. So that's that's taking the messages and classifying them and then this event, this reply display service is actually just taking the traffic art the classified messages and showing them. So the idea is that you would run these at the same time, but my daughter will die.

H

So now, if we get their logs for that, one should.

J

H

But now we're seeing all the events coming through that have been classified with a size of small or large and I mean it's not like groundbreaking classification model, but just for simplification purposes. You know, hopefully someone who wants to do something like this. This is more about how to set up rather than how to build a good classification model, but basically that that's how you can send messages have another service do something to them on the fly and then send a message back out to the ecosystem and consume a new message.

H

That's it that's the original message, sort of transformed or enriched or ever you want to call it I'm, going to try and flick back to my presentation. This thing fail miserably, but let's just try it.

H

Can you see this.

F

No change yet: okay.

H

I'm just gonna leave it here.

H

When I built the classification service, I needed to unmarshal the message that comes through in the cloud event, originally the struck to unmarshal. The message is in the repo for the event source, and it's also in the repo for running this demo.

H

It's a really simple classification model. It just takes the input, values and then mount it and I was it small I'd like to make it more interesting, but just for the fun of playing around founder serves what it's known to do and what I wanted to show you, but seemingly can't, because it doesn't like my screen is some of the things that I wanted to add in the future.

H

So I wanted to try out a more complex ml pattern for like more ml ops, so I wanted to try and look at that something like the rendezvous architecture, which I hope to do soon.

H

I'd like to add some other models as part of that, and there may be a bit more complicated than the one I just showed and I'd like to try out the Python KN cloud events package and work with Python instead of go on some of the services and the repo still were working progress but I hope to add some some extra bits in the next couple of days.

H

Some really good, as of information, that I found, which you guys can't see on the slide, but I'm gonna, try and tell you what the URL descriptions were and the key native doc still busy or a good place to start and I found a really good medium article by I'm, gonna, say the name right now, but zimin when which was about exploring endings image file. That was a really good article.

H

That I went back to you a lot of times to figure out how to do some of this stuff, especially for replying to the broker, and things like that.

H

Mittai this stuff from Metis at ml misperceive for the cluster local stuff, I got really stuck on that when I was first applying this and Marnie Kay native demos, we're really useful as well. I highlighted some areas that I thought could be added to by the community. I think for me, the KN cloud events package, Doc's I thought it would be nice to have a few more use cases for that. I think if you know what it does already, it probably makes complete sense.

H

But if you don't, it was really hard to to sort of get going with it and know how to do stuff. I think also. What would be nice are some more realistic business use cases and patterns, 4k native eventing, I.

H

Think again, if you're, if you're a developer and you're in this every day, you you really get it, but if you're, not so technical or more like higher level business person trying to understand why this is good to do, it would be cool to have some some real business use cases and maybe some more around like the date, science and uh now stuff.

H

Any feedback would be great. I think that if I ever do another, one I can figure out. Why enough it doesn't share my screen, I'm guessing it's probably network.

H

Please play with the demo, let me know what you think and if you've gotten ideas or suggestions like it would be cool to know and that's about it, and so you can see the last slide. I think I explained it. It.

I

Just showed up for a moment, yeah.

H

A

It just it yeah.

K

A

K

The tech problems it was good.

H

And obviously, if if you want just go play with it and give it a try- and hopefully you can find it interesting and.

J

I think it'd be great yeah to get some of these suggestions, you had were fantastic as far as getting more documents and use cases and so forth. So it is definitely a known pain, point, meuk, OPA and so forth. So, but thank you very much for this. This very exciting and interesting stuff, Thanks.

K

Really good demo thanks a lot. Thank.

H

A

So this we have a some more minutes left and the ideas that maybe we discussed with them or any thoughts that it brought up or if you want to ask any questions, this would be the time to to do it. So if anybody has any any other thoughts about Joanna's demo, please do speak up or feel free to chat on the chat box on the side.

H

So I have one myself, which is obviously I deployed the services as Humanity services, which it's, which is fine, I, wanted to try something with Katie serving because I actually wanted to build some sort of scalability into into this. This at some point and try out some scaling stuff.

H

So so it would be cool to see how other people will approach. This I obviously ran into the multiple ports issue with K native serving, and there were some such yes, but it would be really cool to see like what what would be best practice way of doing this. Is it so how I've done it here, or maybe there's other ideas for how you do something like that.

H

You don't have to answer now. You can tell me later.

I

One question: you said: you built a lot of this and go presumably because there are a lot of examples and go what language would you have liked to you sound, like maybe Python.

H

So I wanted to learn, go anyway and I like go. I I would like to play with Python. Actually, interestingly, unless I completely missed it, the KN class I. Would its package for Python has like a neat little booklet with it with some documentation, whereas I think the go? One has nothing so that made me want to use it even more I didn't, but that documentation was quite useful for doing it and go anyway.

H

I think my next step would be to build out a service in Python and use that IBM I think most of my team would probably prefer to use like Java or something like that. I'm, not really a big Java user, but I think that would really be something they'd be looking to use, but for me, yeah probably go apply them.

H

I think it's also like the audience of it. So I think people that you like data science and ammo and stuff are really heavy in Python, which is what Carlos Santana is just typed, so I think for those people to really engage and see what they can do. I think Python would be a good one to to use more and be more with and there's definitely something I want to vlog about, and you do in the future. Maybe.

K

We can see another version of this demo with Python once some of like the screenshare kinks are worked out. Yes,.

H

That would be cool, I think the screen kinks will probably be more difficult than the Python demo by the look of it, but we can try.

I

So you talked a a bit about some of the resources that helped you get your environment set up correctly.

I

How often do you end up needing to you know, update or set up your environment again? Does that cause a lot of pain when it happens, or is that something that, at this point, you know is pretty quick.

H

Actually, it has been quite painful, I. Think, for example, one of the things that I did at the very beginning, when is that playing with K native, was make how to get up and running with K native block. Hey and I really regret it, because whatever I wrote in there is now irrelevant and probably doesn't work anymore, so I and actually I wish that no one would write them because they're all different and that was quite confusing.

H

I wrote my own install script that I ran yesterday to deploy it, which, just because I know it works.

H

I have run the new in some scripts, which we've seen, which seem fine, it'd be nice to know like what the main things are in the new ones are wise, been just. How does it get running compared to how you used to run with the old ones like that I think, sometimes just the background I think again, it's just the difference between being that, you already know in it and someone who just doesn't know what the hell they're doing just being more explicit I guess.

A

So I was wondering, since we couldn't see this light when you work with something, would you like to share your repo on the chat box so that other people can access the demo yeah.

H

Yeah, yes, the repositories and presentation be amazing.

A

And we can work together later on, so you can send me your slides and I'm happy to share them. Of course,.

H

Yeah, that would be really cool. Thank you.

A

A

And are there any afterthoughts or any other comments? Anybody would like to make Oh.

I

One thought would be I, don't know how much extra time Jonah has, but you know, I know that we're gonna try to trim this to put on YouTube, but a separate recording of just you know. The screen screen recording of the slides and the demo, particularly since we have the screen share problems, would be pretty nice yeah.

H

Plus, why yeah, okay, yeah? That's a good idea! Yeah.

A

Free video did, you say, separate, recording that we do again or cutting the recording of the demo from this meeting. I was.

I

Suggesting doing just a clean recording separately of them maybe use some software like OBS or something like that to to just go straight to YouTube, and you know it's great dad.

F

I

In the questions, but having a clean demo would also be. You know a nice thing, particularly since screen sharing seems to have some issues. Yeah.

A
