This is an all out race to control the orchestration of container technology. And, oh yeah, this isn't like other races.

Episode Five: The Containers Derby. Last time we looked at the rise of DevOps and how a new set of tools is tied to new attitudes about the role of developers. In this episode, we track the rise of containers and how they expand the role of developers even further by supporting new kinds of unbounded work. And we'll see how the standardization of containers laid the track for that race toward container orchestration.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><strong>01:30</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>This is a serious race, and a global one, attracting some of the industry's fastest, strongest players. They're all ready to bolt for the finish line. Ready? And they're off.</p> <p>Now, as those horses leave the gate, maybe we should clarify why this race really matters. Who cares about containers anyway? Well, I do for one, but I didn't know that at first. Here's the quick story on how I woke up to the beauty of container technology.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><strong>02:00</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>So, a little while back, I was working on the code base for my website and I brought in my friend Nadia to work on some features. I had been doing a pretty good job on my own keeping my code dry and readable and, of course, well tested. Onboarding a new developer would be easy. Right? Nope, wrong. It was pretty bumpy, especially when we were running specs.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><strong>02:30</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>The code worked, but we couldn't get all the tests to pass on both of our machines. We had weird time zone issues. Her version of Ruby on Rails was different from mine. It was the classic case of, "It works on my machine." "Well, it doesn't work on mine." I'd make changes until it worked for me, then it would all break when I sent it to Nadia.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><strong>03:00</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>I knew the struggle Nadia and I were going through was something all developers went through, even joked about. I just assumed it was part of the job, something you just gotta put up with. What I didn't realize is that there was finally a solution. Imagine there was a way to lower the barrier between people, a new approach where we can use whatever set of tools we prefer and still pass that work around with ease. Imagine there was a way to keep the work consistent as it moves from development to testing and into production, no matter how many people are working on it, or where those people are. Imagine that I had thought about containers before I wasted weeks doing it the hard way.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><strong>03:30</strong> - <em>Liz Rice</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>A container is really, it's a process.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>Liz Rice is a technology evangelist with Aqua Security. She's describing the thing that makes containers so useful, the fact that they wrap everything up in a neat transportable bundle.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><strong>04:00</strong> - <em>Liz Rice</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>It's just like any other process, except it has a very restricted view of the world. So for example, you start a container. The process is given its own root directory, and it thinks that it's looking at the whole root directory of the whole computer, but it's actually only looking at a tiny subset of the file system.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><strong>04:30</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>By wrapping up an executable with all its dependencies, containers can run on any laptop or in any virtual machine in the cloud. It comes with its own executables, its own libraries and dependencies. Everything's contained in a container. So, and this is the magic part, a container is going to run exactly the same in every environment. That means developers can share applications without worrying about the old, "Works on my machine," issue.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><strong>05:00</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>Here's an analogy that might be helpful. You know Blue Apron? That service that delivers everything you need to make a meal? All nicely divided and portioned, recipe card and everything? Well, imagine if Blue Apron also brought you not just the pre-chopped ingredients, but a kitchen stove, and all your cutlery too. Everything you needed in a nice little box on your doorstep. That's a container. In my case, container technology would have made onboarding my friend Nadia a dream, easy as a Blue Apron dinner.

There was such a strong focus on making something that would make the majority of developers and operators lives easier.

Linux didn't start by Linus writing the kernel and telling everybody in user space how to write GCC or how to go build NGINX or Apache. Instead, the kernel team focused on building a very effective core operating system and working with other open-sourced communities like the GNU project to bring the tools that worked on other Unix's into Linux.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><strong>14:00</strong> - <em>Clayton Coleman</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>And so, many of the tools we run today, no one from the core Linux team has ever contributed to.</p> <p>But Linux as a whole is much broader than just the kernel, and I think that that pattern is something that we believe Kubernetes is well positioned to take advantage of. And so as we've built community and focused on scoping Kubernetes, we've tried to think of it in terms of a core Kubernetes, which is about the kernel of a distributed cluster operating system.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><strong>14:30</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>Kubernetes proved itself incredibly good at building community in an open-sourced world. Just like we saw in Episode Two with the rise of Linux, the winner in today's races is often the one who knows how to rally the community. In fact, while Google may have started Kubernetes, now it really belongs to every developer, and it's managed by the Cloud Native Computing Foundation.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><strong>15:00</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>On GitHub, Kubernetes has about 30,000 stars, while Swarm and Mesos have just a few thousand each. That's pretty telling right there. This is technology made by our community, and for our community.</p> <p>I wanted to understand their attitude. How does a massive for-profit company end up playing so well with others? And I found exactly the right person to answer that question. Kelsey Hightower is a technologist working at Google supporting all things container.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><strong>15:30</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>When you think about Google's position, they have a lot of experience doing distributive systems and running things on many, many servers all over the world, so they seem like they were in a really good position to do Kubernetes and to win, and to do this very well. So, when you think about the relationship between Kubernetes and open source, how do you see that relationship?</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><strong>16:00</strong> - <em>Kelsey Hightower</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>I think when it comes to infrastructure tools, and even programming languages, right, there's no choice. You can't really have a proprietary tool, even if it's great. Most people probably won't even look at it if it's not open source. And I think the reason there is that most people will adopt technologies like infrastructure tools like Kubernetes, and you may checkpoint yourself and say, "Well, we're gonna stick with this version for four or five years, or we need to modify it for maybe some of our own unique needs." </p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><strong>16:30</strong> - <em>Kelsey Hightower</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>Once you get to that point, it's gonna be really hard to convince an enterprise to go down the road of, "Hey, it's gonna be $200 per server, and you can't see the source code, so wait for us to modify it."</p> <p>That road is gone. So I don't know if you can actually do infrastructuring anymore without it being open source. And then the second part of open source would be the community that can be attached to it, which I think Kubernetes nailed out of the gate.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>So I wanna go back to the competition. Because it wasn't just Kubernetes as you mentioned yourself, there was Swarm by Docker, there was Mesos by Apache ...</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><strong>17:00</strong> - <em>Kelsey Hightower</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>So, I think when people talk about the battle, I don't know if the battle was really between Mesos and Docker, I think the battle was between people that have nothing. Right, you're coming from homegrown Bash scripts, you're still floundering around trying to get to where you need to be, and the market of people not using orchestration tools is much bigger than the people that have already chosen, let's say, Mesos or Swarm.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><strong>17:30</strong> - <em>Kelsey Hightower</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>So that's what the battle is and will remain. So it's really about helping the end users now. Does Mesos or Kubernetes or Docker Swarm become the preferred choice for people looking to get into a better solution? That's all up for debate, but I'll tell you, people like me, the engineers working on this thing, if you put some of the marketing aside, some of the vendors aside, the people that work on this, I use this phrase “different companies, same teams.”</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><strong>18:00</strong> - <em>Kelsey Hightower</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>A lot of the tools that we build for each other, they end up in the other products some way or other. Right? A good idea is a good idea. So there's no reason to say, "Oh, that's what the Mesos people are doing, let's ignore it. That's kind of silly. So from an engineering standpoint, and a community standpoint, we cross-pollinate these ideas. You almost need that kind of competition so we can all think independently, the best ideas surface to the top and we pick and choose which ones to adopt that target the users in the right way.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><strong>18:30</strong> - <em>Kelsey Hightower</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>So it's still early in terms of this whole competition thing, and again, this thing is zero dollars. You know what I mean? We're not selling this to anyone directly, so it's really more of a platform play, open for everyone, and then users will choose the ones that meet their needs and that's where I think Kubernetes has done a great job in terms of community, being open, and actually solving problems.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-black"> <p class="mb-0"><em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>That was very beautiful.

They're all Lego bricks, you know, we got Kubernetes, you may pick another product for security, pick another product for networking, but at the end of the day, as a developer, you really just want to kinda check your coding and expect that code to land in front of your customer somehow, some way.

Here's my code snippet, under the covers, all the platforms will take your code snippet, wrap it up in a container and run it for you, but they don't need to expose all that to you. So in the future, I think as Kubernetes becomes common, and it's going to level the playing field from big or small providers or people that want to do it themselves, to actually be able to offer these things that only cloud providers could have done, because of the expertise required or the investment in software that was required.</p> <p>This thing will probably end up everywhere, but it'll also be hidden.

Just to give you a sense of how integral they've become, and how quickly, Netflix alone is launching more than a million containers every week.

We've seen how Linux rose to dominance in the first place and how open source attitudes have changed business, workflow, and the tools we use everyday.
