Dockerci

Read configuration of config/database.yml, use that information to launch a circleci mysql docker image.

Add this line to your application's Gemfile:

gem 'dockerci'

And then execute:

$ bundle

Or install it yourself as:

$ gem install dockerci

Simply run:

bundle exec rake dockerci:mysql

It will load your env's database.yml, and using that information, launches the circleci/mysql image.

If you want to specify the launching version, then in your config/application.rb, put following code:

config.dockerci_mysql_version = '5.7'
