  • Ansible 2.1
  • Docker 1.11.2
  • Docker Machine 0.7.0
  • Docker Compose 1.7.1
  • VirtualBox 5.1.0

Install Ansible, Docker, VirtualBox

brew install ansible docker docker-machine docker-compose
brew cask install virtualbox

Create Linux VM by Docker Machine

docker-machine create -d virtualbox <vm name>

For example, VM name is docker01,

docker-machine create -d virtualbox docker01

Setup Docker environment variables

eval $(docker-machine env <vm name>)

For example, VM name is docker01,

eval $(docker-machine env docker01)

Start Container by Docker Compose

install.yml

centos:
  image: centos:latest
  container_name: centos7
  entrypoint: tail -f /dev/null
docker-compose -f install.yml up -d

Check Containers by Docker Compose

docker-compose -f install.yml ps

Ansible settings

ansible.cfg

[defaults]
inventory = ./hosts

hosts

[docker]

centos7

Test Ansible Connection

ansible -i hosts centos7 -m ping -c docker

If success,

centos7 | SUCCESS => {
    "changed": false, 
    "ping": "pong"
}

Ansible Playbook example

setup.yml

- hosts: all
  connection: docker
  roles:
    - common

Provisioning by Ansible

ansible-playbook setup.yml -vvvv
