大限将至! 定义Kubernetes的技术债务将在2022年最终得到偿还! | The End is Near! The Technical Debt of Defining Kubernetes Will Finally Be Paid in 2022! - Hippie Hacker, ii

认证的Kubernetes一致性计划使组织有信心，他们的工作负载将从一个Kubernetes安装到下一个Kubernetes的互操作。
在2017 / 1.9，我们没有一个正式的定义，近90％的Kubernetes不知是什么。CNCF将重点放在提高Kubernetes API的一致性测试覆盖率上，这样你的工作负载就可以在所有的云中运行。
这一努力使我们从1.15的20%的端点一致性测试到1.23的80%以上。
我们将回顾Kubernetes社区的所有专职成员的努力工作，从早期的开创性工作，到最后的原点。终点已近! The Certified Kubernetes Conformance Program enables organizations to have confidence that their workloads will interoperate from one installation of Kubernetes to the next.
In 2017 / 1.9, we didn’t have a formal definition for nearly 90% of what Kubernetes is. The CNCF turned the spotlight on improving the conformance test coverage of the Kubernetes API, so your workloads would run in all-the-clouds.
This effort has brought us from ~20% of endpoints conformance tested in 1.15 to over ~80% by 1.23.
We will look back at all the hard work by the dedicated members of the Kubernetes community, from the early pioneering work, to this final home stretch. The End is Near!

A

Welcome to the imaginarium, I'm hippie hacker, so glad you could join us for this journey. We're going to talk a bit about the cloud native computer foundation and a bit about certified kubernetes, particularly.

A

The journey we've been on together and how we're almost there.

A

One moment, while I drop some beads.

A

So some of our story starts in another community. I was a part of.

A

Chef, I met some really interesting people that chef adam jacobs himself and noah kind of wants code, ranger.

A

Very unique and interesting people adam's, very metal and code. Ranger is very community.

A

They share some some dna around culture being super important. I joke that the revolution will not be televised. It'll be coded not necessarily with chef, but with all of the culture that operational code can bring.

A

Crier is a place for us to chat about said things, and the hashtag here in front of chef is for an irc channel, which is where we used to internet really chat before things like twitter were around and there's a really good story about someone who came to our irc chat, wanting to impress their significant other with some cool food that they would prepare at home, and I loved how noah came forward and included them and said absolutely will give you a hand and that impressed me and I carry that culture forward with me, and I think I also see remnants of that in the kubernetes community.

A

Thank you for noah for bringing that forward and thank you for adam for setting up a company where culture was so important. While I was working there, I got to work at some really. Cool places meet some really cool people, one of them included working on boats, bigger boats, really big boats, cruise ship boats, and I got to work with a couple of people to help them deploy the cloud onto said boats.

A

It was aaron, krickenberger and bob wise now.

A

Onto these ships via satellite, while they were at sea.

A

We would deploy the cloud onto the hardware itself, which I found really fun and really interesting, and I thought about that. For a while, and I really enjoyed my time working with bob and aaron.

A

There were things that were difficult about that time. One was that containerization was just coming into play. Solomon hikes and friends were iterating so fast that it made it hard to develop solutions on top of this technology.

A

We needed it docker on the ships at sea, but we also needed a way to orchestrate that and that's where some of our friends at google came in to play and in their spare time 20 time I think they came up with kubernetes and that helped to orchestrate beyond just having container engine and that ecosystem that developed into something that was beginning to kind of coalesce into something extremely extremely valuable to to all of us.

A

Now we've got kubernetes and we've got docker and I realize that I'd like to play with that. So I began working with some of my friends and there was some servers given to us by by bob the same ones we deployed at sea, and so I worked with some friends of mine and we created a co-op- that's the vault cooperative, so it was myself and lucina taylor and lavelle and and a few others, but these were the core folks. I spent my time with at bulk and we did some pretty cool stuff together.

A

um I've known taylor for all since college were good old college buddies and I ended up going back to new zealand and tried to bring the servers with me, but I did not have the funds. It was quite expensive to get the servers over there. So I reached out to my friend bob I said: hey bob bob said: hey hippy said: can you help me get these servers over there? I said no.

A

But I know someone who I'd like to introduce you to. He said I want you to meet dan dan was working on a new linux foundation thing called the cloud data compute foundation, and he said I think hippie can help you with that, and I really thank you for the introduction.

A

Bob um dan was a real, real visionary and he was thinking about. How can we in this initial state just demonstrate what the cloud is? We worked on demo cncf demo on github and slowly that evolved into things like cncf.ci, which my friends at bulk worked on as well, and when I was back in new zealand, oh.

A

Down here I found a cooperative in new zealand to kind of parallel, the cooperative in the states.

A

That's where ii was born and this cooperative ended up founding it with denver williams as a teenager. He traveled from new zealand to berlin to speak on kubernetes and he has since joined bulk and I'm super proud of it.

A

Cncfci has since been taken over by the bulk team and between volk and ii. We do a lot of the strategic initiatives for cncf.

A

This focus for this talk is all about certified kubernetes and last time I was in china. I brought a friend from new zealand with me.

A

Her name was indigo phillips.

A

Now indy brought her culture with her on that journey, and she shared with us her puppy ha now her peppa hop is her name and her home, her lake and her mountain and the place in which she meets with her people and the canoe in which she arrived on.

A

Her ancestors arrived on and her tribes and there's a another special protocol of introduction that she shared with us called whakapapa, which is the lineage of ancestors from that boat or that waka that first landed in new zealand and it's part of that protocol and that introspection of sharing the identity of who she is indigo, phillips age, 42, new zealand maori.

A

Currently, at that time, speaking at kubecon traveling to shanghai and sharing her culture with the tech world and the sources, the locations she's from are from tauranga bay of plenty altaroid, where we're broadcasting from today and rotorua, which is about an hour from here lovely place and there's a lot of parallels in that introduction that we suggested that maybe we do in our software world as well, where our software might say, here's my version, I'm currently talking to an api server and here's the things I'm doing.

A

At this moment the source and locations being functions inside of our code repositories to identify looking at the history who would be best to talk to to help define what it is that we want to test.

A

Thank you so much indigo for sharing your culture with us and influencing how kubernetes is defined.

A

Now, in order for us to have kubernetes agreed on and defined by us as a community, we need have people who can take a look at it first and say that looks good to me and we need people who can go through and approve it fully and say I am authority in this area. We can approve it. So I'm going to add in a few of those people real quick if I can find them.

A

We're gonna pull out dems, liggett tim hawkin. These were some of our lg tmers.

A

That said, this looks good to me, so we'll put them here within our list of people who helped define what kubernetes is as an lgtmr and in addition, we had john villamark, smarter clayton and timothy sinclair that were part of the approvers for a long time and super thankful that we got there.

A

Slash approve on many of these changes. um Those changes were made.

A

In part, if not mainly by our team at ii- and I have them right here-.

A

Rhian linehans caleb woodbine.

A

Stephen haywood and zach mandel.

A

I love that we have all of these faces that are part of that that wild journey and that I've got to spend some time with and help define what what kubernetes is. um One thing we noted early on in that journey is that ken omichi showed up to one of the meetings.

A

I believe uh um one of the toc meetings and he's like kevin's a governing board meeting. um He said: do you know that we don't actually have tests for around 10 to 11 of kubernetes and we're kind of in shock that that was true and we looked and sure enough. He was right.

A

So dan said: let's do something about that, and so dan shared a picture of his hard drive. This is actually a picture of dan kahn's hard drive with some software that scans the folders he said.

A

Can we do something that might let us look at the kubernetes api that might look something like this and rowan, and some other friends at ii were able to put together an image that looks like this very similar to dan's vision or image of his hard drive called a starburst chart and notice that the end of the bars there's plenty of space in between this is actually untested areas.

A

And so, at this point, when we finally got a graph together, only 14 was conformance tested, which is pretty wild thinking that we all of our applications globally. All of our cube apps um only had a solid surface area of about 15 to work with, but over time we begin to fill in those blanks.

A

You can see here that they got a bit better every time, but this is for every possible api and with our sig architecture meetings and the people who can approve those apis, we slimmed it down to focus just on the apis that were required for everybody, and that means the stuff not within the red or the blue, but only the green.

A

So these are the apis as they've evolved. Here was a 36 of just the stuff available to be tested, slowly filling it in here over time. Here until we get to our most recent one- and this is what's looking really really great- you see the amount of progress we've made and how very few items remain to fill in, and I'm super thankful that we are going to get there this year. This is the year that we wipe out all of that technical debt.

A

We can see that journey most clearly in our up and to the right graph with all the release numbers here at the bottom.

A

I'm really digging that we haven't had any more orange, which was technical debt getting added and we haven't had any um regression. So that means that this is clearly getting smaller and, at this rate, we'll be done within the next two to three releases, and that is very exciting to me. So by you know, cute q, four q, q, three q, two q, three somewhere in there.

A

We should be pretty far along with um squashing all of these out of the way, and that is something I'm super excited and I know dan would be happy to see.

A

This is new endpoints, I believe for 118 and they got introduced without test, and this is part of the gates that we have in place um and those gates are put in place not only for new apis coming through, but for new people submitting their tests.

A

So it's been lovely to see tooling, like heptio's sono boy being used to help people easily submit conformance results and collect them, but they are filtered through robert and uh have to move out of the way for a second we'll help them up here through uh robert guilty's rub kilties and uh berno klein hans's software that runs in prow for helping taylor wagoner defend the certification.

A

So if companies submissions run with heptio sono boy get past the gates defined by rob and burno, then taylor will give them the final approval and they'll have certified kubernetes.

A

So I hope you've enjoyed this journey and I want to thank each of you for your eyes and I want to do um it's kind of a moment to remember dan and kubecon.

A

It was um his vision and belief in each of us that inspired this program to come to being, and I look forward to seeing this come to full fruition and erasing all of that debt.

A

I'll see each of you face to face someday and I die peace.
