This is a collection of docker helper scripts, packaged as a ZSH plugin to make it easier to use with frameworks like zgenom and antigen.

Most of these were collected from blog posts, gists, slack - basically stuff I saw and thought was useful enough to stash away, and I've given credit where I know the source.

If you wrote something I've collected and I didn't credit you, please create an issue or PR so I can correct it.

zgenom

Add zgenom load unixorn/docker-helpers.zshplugin to your .zshrc wherever you're loading your other plugins.

Antigen

Add antigen bundle unixorn/docker-helpers.zshplugin to your .zshrc with your other plugins. You can test drive them without editing your .zshrc by running antigen bundle unixorn/docker-helpers.zshplugin in a running zsh session.

Oh-My-Zsh

1. cd to your oh-my-zsh plugins directory (~/.oh-my-zsh/custom/plugins)
2. git clone https://github.com/unixorn/docker-helpers.zshplugin docker-helpers
