#1 下载镜像
- name: Pull an image
  community.docker.docker_image:
    name: pacur/centos-7
    source: pull

#2 给镜像打标签
- name: Add tag latest to image
  community.docker.docker_image:
    name: myimage:7.1.2   #原镜像名称
    repository: myimage:latest #新打的镜像名称
    force_tag: yes #如果标签重复，强制覆盖
    source: local

#3 删除一个镜像
- name: Remove image
  community.docker.docker_image:
    state: absent
    name: registry.ansible.com/chouseknecht/sinatra
    tag: v1

#4 导出镜像为tar包
- name: Archive image
  community.docker.docker_image:
    name: registry.ansible.com/chouseknecht/sinatra
    tag: v1
    archive_path: my_sinatra.tar
    source: local

#1 启动一个容器
- name: Ensure the test container is running.
  docker_container:
    image: mybusybox:v3
    pull: yes  #无论镜像是否存在，都进行拉取，这种情况可以规避镜像被更新，但是标签没变的情况
    name: mybusybox
    state: started

#2 启动镜像并挂载本地存储
- name: Finer container restart/update control
  community.docker.docker_container:
    name: test
    image: ubuntu:18.04
