Recently I have been using Ansible and Vagrant to test the MySQL 5.7 release candidates but several of you asked about using Docker. The hardest part of this process will be installing Docker on your operating system of choice and that is fairly easy. I am using Ubuntu 14.04 LTS and the installation was a wget command.
Next comes the magic. Docker will download the MySQL 5.7.8-rc
image if it is not already loaded locally and then start
docker run -p 3306:3306 --name mysql -e
