Continuous Delivery with Docker and Jenkins

Installing Docker

We can install the Docker engine using the following task in the Ansible playbook.

tasks:- name: add docker apt keys  apt_key:    keyserver: hkp://p80.pool.sks-keyservers.net:80    id: 9DC858229FC7DD38854AE2D88D81803C0EBFCD88- name: update apt  apt_repository:    repo: deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial main stable    state: present- name: install Docker  apt:    name: docker-ce    update_cache: yes    state: present- name: add admin to docker group  user:    name: admin    groups: docker    append: yes- name: install python-pip  apt:    name: python-pip    state: present- name: install docker-py  pip:    name: docker-py- name: install Docker Compose  pip:    name: docker-compose    version: 1.9.0

The playbook looks slightly different for each ...
