Ansible Role Docker

Install docker on your Raspberry (64 bit architecture).

Role Variables

run_not_in_container - the variable is used to skip some tasks during molecule test. For example, the /etc/hosts file is crucial for Docker's linking system and it should only be manipulated manually at the image level, rather than the container level.

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

  ---
  - hosts: all
    roles:
      - {role: ansible-role-bootstra, run_not_in_container: True }
