A

All right thanks, everybody for staying for the very end, again, no laughs guaranteed, but this is a total experiment, so you are guinea pigs. This is the first ever get ops comedy show so welcome. Thanks for staying all right.

B

Tip your waitress.

A

Yes, all right, so my name is tomo nakahara. I run developer experience at we works. I have my trusted sidekick sebastian here, who's also at weaveworks, and I was really lucky that I invited christian hernandez from red hat as well as chris short, but chris short is now short on time and.

C

A

To record a radio show in three minutes so.

B

Good news, for you is that chris short was the funny.

C

One yeah he was the funny one. So that's why we need it we'll find.

A

Out yes, so first quiz question is christian: are you doubly as funny half as funny or .233 as funny.

C

I am I'm fractually fractionally funny he impersonates fine, not not, as I don't have as nice as voices he does. But I try.

A

C

No, no one has the radio voice of chris.

A

Okay, so quick plug, though hopefully you guys saw the cards for us, is very, very exciting. Please join us next week on october 20th on this get ops, one stop shop event where you will see all these amazing companies show how they offer git ops to their enterprise customers. So if any of you are thinking to start uh working with git ops and want to use one of these platforms, please join us. The website is getoffsdays.com same one.

A

That may was talking about as our various uh talks on getups get ops days, so we just put on the same site. So please join us for that next wednesday, um all right! So, as I mentioned, this is all participatory. So hopefully, if you use twitter check out our brand new handle, which is at get ops comedy, so this all experiment we'll see if this works so as.

C

Interactive by the way sergeant rob interactive, so we really do want you to go and pull up the account. Yes for.

A

Those of you online for those of you here, um hopefully you can see the polls that our trusted assistant scott over there will be um tweeting out at the right time. So at that time like put in your votes and then we'll see the results and see if this works, we're.

B

Not kidding these are the tweets people yeah.

A

They seem to be distrusting that people will tweet, but I understand not everybody's on twitter, but we'll try this out um all right. So we're going to do an easy one, and maybe christian do you want to read off so we're going to do easy one? um What is githubs yeah.

C

What is getup so first choice: a compliant way to do operations that uses git for version control with an audit history and number two. Two.

A

A way to minimize downtime, because a git repo is a single source of truth for changes and rollbacks.

C

Number three: a way to automate manual tasks that increase velocity.

A

Or for all of the above.

C

All the above, yes, sometimes that's. That was my favorite answer in college. It got me through college. Yes, it's all the above.

A

So, to give you some time, first of all, does everybody see the tweet? Did scott get the tweet out? Yes, excellent. Everybody's voting rapidly.

C

A

And christian sebastian any thoughts.

B

Oh, why do we not have a choice for like a declarative source of pain? Yes, yes,.

A

Well, the fourth one was all of the above and much much more.

C

Okay, there you go.

A

With that we're going to see if this actually works and we'll slide over is.

B

More really an option yeah more as an option.

C

B

A

Can't buy my mouse- oh my god, I'm going to need the tech help, because my mouse is invisible.

B

You guys just gotta shake the finger. We it's what I do when I get nervous.

B

A

Seriously, it is.

B

A

Yes, it does look a little okay. Well, we're gonna have to trust even.

B

The shake the finger.

A

Okay, scott yell out: what are the poll results? Okay, uh the poll results.

D

We have a mic. I don't need to shout it. uh The pull uh shout out uh metaphorically okay, so the poll results are ops with get version control. Nine point: one percent.

A

Well, just tell us the top one: what's the top top one, oh.

D

The top one is is all the above: okay yeah. Ninety ninety point.

A

Congratulations on that, um so one thing we definitely want to mention, as has been mentioned many times today, um you know we are um really committed to get ups. Obviously that's why we're here um and we think it's really really important- that there is a cncf official entity out there that kind of governs those definitions and those principles, so we're so excited that um they've been published and kind of official.

A

So, thanks to the hard work of the many members and the chairs, especially including people like dan and scott working in the get ops working group, so please check that out all right.

B

I'm here because they're paying me sorry, I'm here because they're paying me and oh.

A

We got one laugh.

B

There you go, you've got eight laps, that's the first one, I've ever intentionally gotten, I'm mostly unintentionally. Funny yes,.

A

All right, so, hopefully you got the hang of this, so um we are very lucky that many of you might know javari khan, who is definitely one of the top skidops practitioners out there and currently works at snowflake and has done git ops at previous companies. So javario very kindly has done these pre-recorded bits that will be part of our quiz. So I'll do a quick, bio.

B

And I'll let you know that before we got up here, timeout who's, a star trek fan, wanted me to do the car. I refuse because.

A

Pronounces the name han.

E

Hi everyone, I'm javerijan, I'm a senior platform engineer here at snowflake, um I've been in this infrastructure domain for the past seven years and specifically with kubernetes for the past four I've been a part of different infrastructure teams that have spanned over startups and enterprise on-prem and also multi-cloud. At the moment, I mainly have experience managing high volume deployments and supporting infrastructure build up with a special focus on reliability and automating everything related to github to aid our developer productivity.

E

uh In my current position right now, um I support the building and maintaining of our container platform here at snowflake, um which comprises a multi-cloud kubernetes cluster environment.

A

Excellent, so we are in very good hands, so thank you to javaria for providing some of these um actual real-world experiences and thoughts that come from that all right. So our next real question is um what ideal, what are uh ideal environments for git ops.

C

Christian so um everywhere, every environment, everything you.

A

Can use git ops for everything.

B

Just everything I get up's my dog, that's.

A

Right gabe get.

B

Up to my bathroom.

A

It's true, as many.

C

A

Saying some people say they want to start get off, seeing all the things yeah.

C

Get off seeing all the things exactly get ops is only for production. Take time to set up and use it uh number three would be get. Ops is only for test dev staging you don't want to scale it and then uh number four get ops is for home tinkering. I I can choose any one of these, but I definitely use it for home tinkering. Yes,.

A

Or I guess it's for only um all right, so hopefully, you've started voting start.

B

Seeing the poll hi scott, I think of all the missing options that we could have had get upset for fun.

A

All right, those of you online and here all right. I think that's a good enough time so scott. What's the top vote.

D

Okay, well uh right now we have hang on hang on. Let me just refresh this: we have nine votes. Oh, let's let people catch up a little bit. Last.

C

B

Okay: okay: 23 votes. You forgot.

D

To refresh that's what it is: eventual consistency; okay, that's right, um yeah, so yeah.

A

It's 250 votes right right.

D

Come on everybody, okay! It's we! We got this! We got this okay, so uh top vote right now is everywhere. 91.3 percent, so.

A

Home tinkering.

D

Only 8.7 percent- oh god, you guys are so smart.

B

Yeah controls got some trolls in here. The answers are not obvious at all. We've got, you know all.

A

Right so yes, hopefully you saw that uh again and as we go a little bit more into these details, it's not that there's a right or wrong answer. These are sort of the experiences that javaria has so don't feel bad or feel like it's focused in a particular way. But yes, for this one still fairly broad and gidops all the things all right. So, uh oh, yes and javier is going to share a little bit from actual experience.

E

So in all of my experiences, we've used get ops for staging and dev and for production environments and certain tools like flux, they're, not only easy to set up, so they are ideal for test or frequently updated environments, but they are also scalable enough for production use cases. um For example, argo cd and flux have first class for multi-tenancy and they are also provide a host of security features for production environments, so, in a nutshell, um get offs can be used everywhere.

B

Excellent, I don't know which javario I'm supposed to be looking.

C

For yeah, I know it's a little duality there. Well, javaria is everywhere, that's right, just like get-offs.

B

All right, I'm more.

A

B

By that than by the kid.

A

We're gonna dig a little bit deeper now so um so, if you need to test clusters that are spun up and down regularly and need frequent updates for application changes, what git ops tools might you use? So this is a little bit trick question because we're going to have to try to guess what javaria did so, one christian flux.

C

Notification server to update prs with deployment results.

A

C

Argo cd and yaml files in a single repo or or you need flux and helm, customized, single repos or or again. My favorite answer got me through college. All of the above.

A

Which is possible.

C

B

It is possible. Yes, I really did write an answer to this question that you didn't put in there. I just read bash.

C

Everything until.

A

While we're waiting for the votes to come in, uh there are people who do bash. What would be some.

B

A

I'm not joking, what would be some uh things that might not work out, maybe at scale or whatever.

C

Up until recently, there was a bunch of bash in kubernetes right in the static pods. What's wrong with that.

A

Yeah, what could ever go wrong with a.

C

Bunch of batch scripts.

A

Again, it's all use cases right, so people have different um all right, scott. How is it looking don't say the number, because it's in the hundreds I.

D

Will not say the number um also I was about 10 seconds late, so that was my bad. uh So.

A

D

Everyone just another moment.

A

Wait you're saying you didn't wait.

D

19 seconds: oh 19 minutes, no okay, we got 19 votes, we've got 19 months, so you weren't paying attention. I was basically.

B

Not interesting enough.

D

I feel like I'm in middle school again.

B

Sebastian, okay, they wouldn't let me on stage in middle school.

D

C

Very good reasons, various reasons.

D

All right: well, then, uh you know we have um 19 solid votes, let's say: 20 votes, okay, top vote. Okay divergence uh top vote is, it is all the above, but not by a 90 plus percent margin only by 52 percent. Oh all,.

A

Right what was.

D

The second second second vote is a second highest vote is 21, and that is argo. Cd and yaml files, yeah.

A

Interesting well again, this was uh just what javari has done, so why don't we hear what your various to say, who actually uses all kinds of technologies and tools, not just one.

E

So, in my specific experience for these kinds of environments, I used flux with a combination of helm or customized and with small single repositories, because they're, obviously test clusters, the reason being that, as kubernetes is getting more and more widely adopted, we're seeing many companies adopting a development life cycle that allows developers to spin up these testosterone clusters on demand and use them for testing their applications right from the start.

E

This is great because developers get to test how their applications will behave in a containerized environment that is as close as possible to the production one. But in my opinion the biggest benefit get-offs tools offer here are automating the update cycle and cutting down the time it takes to get new changes on these test clusters.

E

Now, since these are frequently deployed and destroyed clusters, you want something that is quick and easy to set up every time, and I think flux offers this simplicity and with just a few steps, you can have a get ops based workflow up ready for your test environment. uh This installation is as easy as deploying any other typical pod in your cluster, but then generally, I would say the most useful feature for these kinds of environments. Is the automatic imageable feature that flex has so?

E

Basically it not only watches the manifest in your repo, but the automatic imageable feature will deploy new application changes as soon as it sees these new images in your registry. So you don't have to even do any changes or any um pushes for just that specific uh chain set as well.

B

Cool cool- thank you by now. You guys are all probably wondering why javari is not up here. Trying to tell the jokes. She did write out a bunch of jokes for us. She's she's a planner, but I forgot them all, because I have no working memory. Yes,.

A

So we prepared plenty of extra ones if you're interested in following up with us, we're happy to chat with you about more best practices and such, but given the 10 constraints, we'll skip ahead, and just thank you oops for coming. uh We really appreciate it again, um come to our october 20th event and christian and uh chris are always on every thursday right. Every.

C

Other thursday, every other I do twitch we're on twitch primarily, but you can also catch us on youtube. um Get ups guide to the galaxy.

B

I made my youngest child zaphod and that you can join a huge hitchhiker's guide fans and uh I consider it equal to the bible in many respects. My next question was: are you? Why are you guys still here yeah.

A

We will end thank you for coming to oregon.

C

Thank you very.
