shell 執行命令

執行任何 shell 命令，可使用管道，但對一些複雜的命令太不支持，好比 awkdocker

[root@Ansible ~]# ansible hosts -m shell -a "ifconfig eth0|grep 'inet'"

copy 配置模塊

  • src --- 推送數據的源文件信息
  • dest --- 推送數據的目標路徑
  • backup --- 對原來的文件，會放到 /var/lib/docker/overlay2/ 目錄下
  • content --- 直接批量在被管理端文件中添加內容
  • group --- 將本地文件推送到遠端，指定文件屬組信息
  • owner --- 將本地文件推送到遠端，指定文件屬主信息
  • mode --- 將本地文件推送到遠端，指定文件權限信息
