I played with Docker a bit yesterday. Containers really are awesome! VMs look almost stupid in comparison. I'll be using it as much as I can. Being written in Golang doesn't hurt either... Golang seems like a very good choice for this.

It is called Go!

Not if you want to search for it.

I still think this is karmic justice for Google usurping the name of the existing programming language called Go! :)

This is exactly what I've been looking for, a clear walk-through of Docker.

There are more links like this. For a list of the ones I have compiled so far check out this page.

https://github.com/dotcloud/docker/issues/614

Feel free to add to the list if you know of some I forgot.

I'm also planning on writing my own Docker for dummies tutorial that goes from beginning to end explaining how to use each part along the way. Now I just need to find some time to put it all together.

I would love to see more conceptual materials, explaining the ideas behind it, why I should use it, use cases, comparisons to alternatives - that kind of reading. It seems promising but a little hazy from a high level.

It's probably also worth mentioning dokku, which is a simplified private PaaS built on top of Docker. It adds Heroku buildpacks (Ruby, NodeJS and Java right now) into the mix, and a git push-to-deploy model.

Because dokku has a concise and readable codebase, browsing the source is a good way to see one practical application of Docker, too.

I've set it up as a sandbox environment for developers at my company, and for our purposes it's a much better fit than some of the more heavyweight private PaaS products. I'm really enjoying working with it!

get familiar with openvz - linux containers that allow to configure network interfaces, dynamic resources allocation, etc

Example from http://openvz.org/Basic_operations_in_OpenVZ_environment:

[host-node]# vzctl create 101 --ostemplate fedora-core-18-minimal [host-node]# vzctl set 101 --ipadd 10.1.2.3 --save [host-node]# vzctl set 101 --nameserver 10.0.2.1 --save [host-node]# vzctl start 101

OpenVZ is basically identical to lxc, which is one of the underlying components of Docker.

Docker could be ported from lxc to openvz (and probably will be in the future as a plugin, as it has been requested).

That is to say, Docker is not a replacement for OpenVZ, or any other low-level container capability. It's simply a higher-level tool which is built on top.

Yes, LXC and OpenVZ in it's core similar technologies that enable linux containers. OpenVZ also comes with varios containers management tools, some of which are available via docker for LXC containers too.
