    Great article, a couple of comments:

      root@dinospace: wget -qO- \
  https://raw.github.com/progrium/dokku/master/bootstrap.sh \
  | sudo bash
    First, if you're already logged in as root, there is no[1] need for sudo. Secondly, I know this is how dokku recommends installing, but a) running wget as root probably isn't the best idea, and b) pulling down a shell script and running it as root is a really bad idea. At least download the script and check that you're running what you think you're doing (in fact, you'll see that the script is just a short list of things, few of which needs to be run as root).

      ana@local: cat ~/.ssh/id_rsa.pub | \
  ssh root@dinosaurspaceships.org \
  ā€œsudo gitreceive upload-key usernameā€
    Same thing - either give your regular user sudo privileges (and prepare to have to enter your password, unless you specify to not need one -- in which case that should be limited to eg the gitrecieve command) -- or just drop the sudo.

    I think docker is a great project, but I would like to see more support for running it under different user(s) than root. Looks like I'm not the only one:

    [1] sudo does some logging, but that is mainly helpful when it can log a "useful" user name, not "root" -- ie: you can see who broke the server, if more than one person has sudo access.

    >Docker powered mini-Heroku in less than 100 lines of Bash

    Can I use this to deploy Rails application like I do on Heroku, or is it Nodejs only at the moment?

    I'm currently in a limbo between WebFaction (VPS with some configuration hand holding) and DigitalOcean (you're on your own).

    Does it feel like Docker is picking up some steam right now? I like the concept but am still wondering if Docker is a better approach than going straight to the machine. How necessary is the 1GB droplet (vs 512mb)?

    Great read. I could see incorporating this into my stack... In any case, I was happy to learn about each of the tools/projects mentioned within - especially stoked about Docker!

    This is awesome. These are four technologies that I'm currently learning - good timing.

    Does that mean Ubuntu on DigitalOcean has Docker support out of the box?
