Docker 用ansible给主机安装docker

1、ansible管理机准备

yum install -y ansible

编辑hosts文件，连接测试 ansible all -m ping

下载仓储

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

2、docker.yml

• hosts: dks 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: change shell: curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://f1361db2.m.daocloud.io
  • name: start docker service: name=docker.service enabled=yes state=started

3、执行：

ansible-playbook docker.yml

yml中忽略错误： ignore_errors: yes
