ansible安装docker

首先配置好docker安装的yum源

wget -P /etc/yum.repos.d/  https://download.docker.com/linux/centos/docker-ce.repo

docker.yml

- hosts: node
  remote_user: root
  tasks:

    - name: setup yum-utils
      yum: name=yum-utils state=present
    - name: setup device-mapper-persistent-data
      yum: name=device-mapper-persistent-data state=present
    - name: setup lvm2
      yum: name=lvm2 state=present
    - name: cp docker.repo
      copy:
        src: "/etc/yum.repos.d/docker-ce.repo"
        dest: "/etc/yum.repos.d/docker-ce.repo"
    - name: setup docker-ce
      yum: name=docker-ce state=present
    - name: start docker
      service: name=docker.service enabled=yes state=started

安装过程

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

192.168.0.132              : ok=7    changed=1    unreachable=0    failed=0  

如上，安装成功。

使用ansible node -m command -a "docker -v"检查

[root@feiyu etc]# ansible node -m command -a "docker -v"
192.168.0.132 | SUCCESS | rc=0 >>
Docker version 18.06.0-ce, build 0ffa825
192.168.0.131 | SUCCESS | rc=0 >>
Docker version 18.06.0-ce, build 0ffa825

就此，ansible安装docker成功
