I'm not talking about isolation WRT to containers and security, keeping them up-to-date is the bigger issue. Docker doesn't have a good solution to this that doesn't involve constantly rebuilding your base containers and any child containers that depend on it.

That's not a "security story" I've heard before. Surely containers make this much _easier_ than traditional VMs, because containers are designed (or should be designed) to completely expendable. To do an "OS upgrade", just rebuild and redeploy. If you're using a system that has rolling, verified, graceful restarts built in (e.g., Marathon, and I believe Kubernetes does, too), you'll easily avoid any downtime, which i…

Major problem is there is a substantial lack of tooling to handle this. Meanwhile, managing updates for all of my servers is pretty painless with the plethora of system management tools out there - puppet keeps all my packages updated from my local yum repositories and restarts services as needed (aside from critical ones like postgresql that require manual intervention).

And what's their business model going to be like? Freemium as in Nginx Plus? Pay for monitoring? Support and Consulting?

Kubernetes is an open source project sponsored by Google. Google offers hosted Kubernetes for the cost of the servers and calls it Google Container Engine. It makes their Cloud Platform more attractive. Ideally, the dependence on Google goes down over time. CoreOS maintains and builds kube-aws[1].

>Ideally, the dependence on Google goes down over time.

I know that you're referring to development but just wanted to point out to anyone that might think you're referring to their cloud service that you're not.

I generally Prefer HTML over PDF, especially on mobile, but I'm genuinely curious as to why someone would be cautious about opening PDFs.

Just a little bit of meta discussion: HN is generally good about this, but at the time I'm writing this, this comment is greyed out. It's a reasonable question that I might have asked 5 years ago. They're not bringing down the level of discourse, they just didn't know something that is common knowledge. I feel like software people, if anyone, should be sympathetic towards people with holes in their knowledge, because…

Well said.

I hope you didn't take offense to the question. I recognize Docker's contribution to the containerization landscape, but after doing tech for ~15 years, you see things come and go and you get tired of wasting your time on products or tooling that may or may not be around in 1-3 years.

Given the Docker engine has been around for a number of years and it's still picking up steam, containers aren't going away anytime soon. That said, Docker Inc. has plenty of cash in the bank.

I never said containers are going away. I implied its going to be hard to make money off of containerization.

According to this intro https://docker.wistia.com/medias/mdseh9gv6v , 200 out of 230 people working for Docker Inc are engineers. I like the ratio.

This "Universal Control Plane" thing looks pretty enterprisy. I have to imagine they are ramping up an enterprise sales team now, with all the org changes that come along with that. This product sort of reminds me of Citrix and Xenserver.

I signed up for UCP and was contacted by a few guys at Docker to go over the features. It was an hour-long presentation. They wanted something like ~$1,500 per node. I'm still not exactly sure what a `node` entails. The salesman seemed extremely technical and was able to answer all of the questions I asked. Too bad their website isn't able to give me the directions for using UCP without me clicking on the "sign-up" button (which now doesn't work because I've already signed up), or else we might be using it to deploy at Adobe.

I've written a report about it for a class last month and it may help you have a better understanding of Swarm/Kubernetes/Marathon: http://armand.gr/static/files/htise.pdf

Read the report and it was worth my time. Good reading for any systems person. Thanks for posting it. Suggestion: Please include a license if one was not (did not notice). Publish an HTML version.

Not sure if this is helpful, but Firefox uses the pdf.js extension to open pdfs within the browser. Perhaps other browsers have extensions based on pdf.js?

Between this, Kubernetes, Marathon, Amazon's container service, the tooling is overwhelming. I really have no clue how it all fits together and what a complete setup looks like (dev -> testing/CI -> prod). I'm using Docker for development, but that's where it ends for me.

Those are too low level for most users and you'll eventually end up (poorly) re-inventing a PaaS if you need things like configuration, authorisation, scaling, routing, rollbacks, etc. I've found Deis ( https://github.com/deis/deis ) to hit the sweet spot between flexibility and convenience. It is built on top of docker and Kubernetes (CoreOS/fleet in v1), and lets you deploy docker containers natively and/or automat…

I'm amazed at how inaccurate this comment is. Every single thing you listed there is supported in Kubernetes 1.2.
