Ansible is an amazing piece of configuration management software. Among its amazing features is that it’s totally agentless and the only 2 packages that it needs on any host are python and an SSH server.
Today we will create a playbook that will do the following:
- Add the stable docker repository to the software sources
- Add the gpg key
- install docker-ce package
It’s assumed that you have already added all required hosts to /etc/ansible/hosts and I’m naming this group “swarm”
- hosts: swarm remote_user: qcri\aamr gather_facts: no tasks: - name: add docker repo apt_repository: repo="deb https://download.docker.com/linux/ubuntu xenial stable" state=present - name: install repo gpg key apt_key: url="https://download.docker.com/linux/ubuntu/gpg" state=present - name: refresh cache and install docker-ce apt: name=docker-ce update_cache=yes state=latest
