Stacker

Stacker is a container manager for Docker

This is currently beta software. You can find me as cnf on the channel #docker on irc.freenode.net

pull requests, especially for documentation, are welcome. For new features, open a ticket or poke me on irc.

docker pull frosquin/stacker:dev gets you the dev version, which is mostly up to date with the devel branch.

make image will build a docker image of your own.

You can find the full documentation here
