Ansible 2.8 (with Mitogen)

Running Ansible 2.8.12

• 2.8-alpine-3.11 Dockerfile
• 2.7-alpine-3.10 Dockerfile
• 2.8-ubuntu, 2.8-ubuntu-18.04 Dockerfile

To leverage Mitogen to accelerate your playbook runs, add this to your ansible.cfg:

@TODO This needs updating, please investigate in your container the location of ansible_mitogen.

strategy_plugins = /usr/lib/python2.7/site-packages/ansible_mitogen/plugins/strategy
strategy = mitogen_linear

Running

**You will likely need to mount required directories into your container to make it run (or build on top of what is here).

Simple

$~   docker run --rm -it willhallonline/ansible:2.9-alpine /bin/sh

Mount local directory and ssh key

$~  docker run --rm -it -v $(pwd):/ansible -v ~/.ssh/id_rsa:/root/id_rsa willhallonline/ansible:2.9-alpine /bin/sh

Injecting commands

$~  docker run --rm -it -v $(pwd):/ansible -v ~/.ssh/id_rsa:/root/id_rsa willhallonline/ansible:2.9-alpine ansible-playbook playbook.yml

Bash Alias

You can put these inside your dotfiles (~/.bashrc or ~/.zshrc to make handy aliases).

alias docker-ansible-cli='docker run --rm -it -v $(pwd):/ansible -v ~/.ssh/id_rsa:/root/.ssh/id_rsa --workdir=/ansible willhallonline/ansible:2.9-alpine /bin/sh'
alias docker-ansible-cmd='docker run --rm -it -v $(pwd):/ansible -v ~/.ssh/id_rsa:/root/.ssh/id_rsa --workdir=/ansible willhallonline/ansible:2.9-alpine '

use with:

$~  docker-ansible-cli ansible-playbook -u playbook.yml
