Ansible安装docker

设置主机清单 `vim /etc/ansible/hosts`

[docker]
192.168.0.[8:10]

① 在`roles`目录下生成对应的目录结构

[root@admin roles]# ansible-galaxy role init dockekr
- Role dockekr was created successfully

[root@admin roles]# ls
dockekr  docker.yml  mysql.yml  docker  docker.yml

[root@admin roles]# cat docker.yml
---
- hosts: docker
  remote_user: root
  roles:
    - docker


[root@admin roles]# tree dockekr/
docker/
├── defaults
│   └── main.yml
├── files
│   ├── daemon.json
│   └── install_docker.sh
├── tasks
│   ├── install.yml
│   ├── main.yml
│   ├── restart.yml
│   ├── start.yml
│   ├── status.yml
│   ├── stop.yml
│   └── uninstall.yml
└── vars
    └── main.yml


8 directories, 8 files

② 定义 tasks 任务文件

vim /etc/ansible/roles/docker/tasks/main.yml

---
- include: install.yml

install.yml

---
- name: install docker
  script: ../files/install_docker.sh *
  #yum -y install docker-ce-20.10.17-3.el7 docker-ce-cli-20.10.17-3.el7 containerd.io docker-compose-plugin

start.yml

---
- hosts: docker
  remote_user: root
  tasks:
    - name: start docker service
      script: ../files/install_docker.sh start
#      shell: systemctl start docker
      tags: startdocker

stop.yml

---
- hosts: docker
  remote_user: root
  tasks:
    - name: stop docker service
      script: ../files/install_docker.sh stop
#      shell: systemctl stop docker
      tags: stopdocker

restart.yml

---
- hosts: docker
  remote_user: root
  tasks:
    - name: restart docker service
      script: ../files/install_docker.sh restart
#      shell: systemctl restart docker
      tags: restartdocker

status.yml

---
- hosts: docker
  remote_user: root
  tasks:
    - name: status docker service
      script: ../files/install_docker.sh status
#      shell: systemctl status docker
      tags: statusdocker

reload.yml

---
- hosts: docker
  remote_user: root
  tasks:
    - name: reload docker service
      script: ../files/install_docker.sh reload
#      shell: systemctl daemon-reload
      tags: reloaddocker

uninstall.yml

---
- hosts: docker
  remote_user: root
  tasks:
    - name: uninstall docker
      shell: yum remove -y docker-ce docker-ce-cli containerd.io docker-compose-plugin
      tags: uninstalldocker

ansible-playbook ./docker/tasks/uninstall.yml

③ 编写安装 shell 脚本

vim files/install_docker.sh

#!/bin/bash

}

    ;;

    main >> ./install-docker.log 2>&1;;
esac

③ 定义 vars 变量文件

[root@admin docker]# vim ./vars/main.yml
---
# 变量==1安装最新版本，!=1则安装变量指定的版本（20.10.17-3.el7）
docker_version: 20.10.17-3.el7

④ 定义 docker 剧本文件

[root@admin roles]# vim ./docker.yml
---
- hosts: docker
  remote_user: root
  roles:
    - docker

⑥ 启动剧本

剧本定义完成以后，我们就可以来启动服务了：

[root@admin roles]# ansible-playbook docker.yml
