Ansible role to manage and run the nginx docker container.
you will need to ensure that a recent-ish version of docker-py
and docker are installed.
We use tests/requirements.yml to install the dependency role: geerlingguy.docker
You can use also ansible-galaxin install -r tests/requirements.yml or better add the same content to your own requirements.yml file in your own repository.
Use it in a playbook as follows, assuming you already have docker setup:
- hosts: 'servers'
roles:
- role: geerlingguy.docker # You can use any other role to install docker, but docker is a requirement (see obove)
- role: 'myrole.docker-nginx'
become: yes

}Have a look at the defaults/main.yml for role variables that can be overridden! If you need a playbook to set Docker itself
