ansible部署docker

1. 创建ssh密钥并发放到远程机子上

ssh-keygen  #生成密钥，默认回车即可

ssh-copy-id root@192.168.35.14   #拷贝密钥至主机

2. 写容器剧本

vim docker.yml

---
- hosts: gyh4
  remote_user: root
  tasks: 
    - name: 挂载光盘
      shell: 
        cmd:
          mount /dev/sr0 /media/

    - name: 配置阿里yum
      get_url: 
        url: http://mirrors.aliyun.com/repo/Centos-7.repo
        dest: /etc/yum.repos.d/
    - name: 切换镜像源
      get_url: 
        url: https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
        dest: /etc/yum.repos.d/

    - name: 安装特定版本的docker-ce
      yum: 
        name: docker-ce-18.06.3.ce-3.el7
        state: present

    - name: 添加配置文件
      file: 
        path: /etc/docker/
        state: directory

    - name: 添加配置文件
      file: 
        path: /etc/docker/daemon.json
        state: touch

    - name: 修改daemon配置
      lineinfile: 
        dest: /etc/docker/daemon.json
        line: 
          '{"exec-opts": ["native.cgroupdriver=systemd"],"registry-mirrors": ["https://kn0t2bca.mirror.aliyuncs.com"]}'

    - name: 启动docker
      service: 
        name: docker
        enabled: yes
        state: started
...

3.执行剧本

ansible-playbook docker.yml

4.测试

在远程主机输入

docker ps

大成功！！！
