1.新增host配置到/etc/ansible/hosts文件中

[docker]
192.168.43.95

2.配置无密码登录

# 配置ssh,默认rsa加密,保存目录(公钥)~/.ssh/id_rsa.pub
ssh-keygen -t rsa

# 配置无密码登陆,这里需要分别4次发送至4台服务器
ssh-copy-id -i ~/.ssh/id_rsa.pub root@ip

3.编写playbook

---
- hosts: docker
  remote_user: root
  tasks:
    - name: install yum-utils
      yum: name=yum-utils state=present
    - name: add docker repo
      shell: yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
    - name: install docer-ce
      yum:
        name: docker-ce
        state: present
    - name: install docker-ce-cli
      yum:
        name: docker-ce-cli
        state: present
    - name: install containerd.io
      yum:
        name: containerd.io
        state: present
    - name: config mirro
      copy: src=~/docker-daemon.json dest=/etc/docker/daemon.json
      tags: configmirro
    - name: start enable docker
      service: name=docker state=started enabled=true
    - name: restrat
      shell: sudo systemctl daemon-reload && sudo systemctl restart docker
      tags: restart

mirror配置

[root@localhost ~]# cat docker-daemon.json
{
  "registry-mirrors": [
    "https://registry.docker-cn.com",
    "http://hub-mirror.c.163.com",
    "https://docker.mirrors.ustc.edu.cn"
  ]
}

 

4.运行playbook

 ansible-playbook -v install_docker-ce.yml
