编辑一个yml文件，如下

---
  - hosts: test
    tasks:
      - name: cp docker.repo
        copy:
          src: "/etc/yum.repos.d/docker-ce.repo"
          dest: "/etc/yum.repos.d/docker-ce.repo"
      - 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: setup docker-ce
