Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

Multiple MySQL Versions for Development

Options included below:

Using Docker docker-compose
Using Homebrew brew

Using Docker (recommended)

This gist was originally created for Homebrew before the rise of Docker, yet it may be best to avoid installing mysql via brew any longer. Instead consider adding a barebones docker-compose.yml for each project and run docker-compose up to start each project's mysql service.

Install MySQL on OS X El Capitan

Normally the installation of MySQL can be achieved with a single command, which executes a script provided by MacMiniVault : bash <(curl -Ls http://git.io/eUx7rg)

However, at the time of writing the script is not compatible with OS X El Capitan (10.11)

Install MySQL using Homebrew

An alternative to the aforementioned installation script is installing MySQL using Homebrew. This gist assumes you already have Homebrew installed, if not first read the article "Homebrew and El Capitan"

Make sure Homebrew has the latest formulae, so run brew update first
