本文提出了使用 Ansible 自动安装 Raspberry Pi 上的 Docker，并使用自制角色。
先决条件
- 已在目标 Raspberry Pi 上安装了 Raspbian，安装过程可以参考前一篇文章Raspbian 在 Raspberry Pi 上的自动初始化和安全
Docker 安装
角色获取 我已经开发了一个 ansible 角色用于此自动化，如下所示获取它：
git clone https://gitlab.com/jls42/ansible-rpi-docker.git roles/ansible-rpi-docker
有关更多详细信息，请参阅ansible-rpi-docker 的文档。
创建名为 inventory 的清单文件 在此清单示例中，Raspberry Pi 具有 IP 地址 192.168.1.190
[rpi1]
192.168.1.190 servername=rpi1
准备 docker-rpi.yml 播放书
---
- name: "Installation de Docker sur le Raspberry Pi"
hosts: rpi1
remote_user: "pi"
roles:
- roles/ansible-rpi-docker
vars:
docker_version: 18.06.1~ce~3-0~raspbian
部署 Docker
export ANSIBLE_HOST_KEY_CHECKING=False
ansible-playbook -b -i inventory docker-rpi.yml
这将得到：
jls42@boo:~/rpi$ ansible-playbook -b -i inventory docker-rpi.yml
