MySQL Master/Slave(s) with Docker (for Mac) containers

Create a MySQL environment with Docker (for Mac). Single server or a Master and multiple slaves.

Requirements

• ansible 2.3.2.0
• Docker for Mac
• docker-py Python module
• pyyaml Python module

For the python modules, just run:

wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py
pip2 install docker-py
sudo pip install docker-py
sudo pip install pyyaml

Role Variables

Two main variables you need to know: "servers" and "mysql_image_version". Servers is the amount of containers you wish to deploy, is an integrer value.

mysql_image_version can have 2 options: 5.6 or 5.7.

The default values are: servers=1 and mysql_image_version=5.6

Example Playbook

- hosts: all
  gather_facts: False
  roles:
      - containers

There's just 1 role. To execute it, run a command as follow:

ansible-playbook /Users/daniel/ansible/docker-mysql/site.yml -i /Users/daniel/ansible/docker-mysql/hosts --extra-vars "servers=5 mysql_image_version=5.7"

In the above case, 1 Master and 4 Slaves will be deployed, using MySQL 5.7 (Percona images)
