例如docker inspect，支持go格式，
没有指定格式：

  1. # docker inspect xxx |head
  2. [
  3.     {
  4.         "Id": "2308ce12ad3aef6f81350a10f54edf07f31d0b340b5dbc2af4d1cc9220ebd551",
  5.         "Created": "2022-02-07T09:52:54.256212196Z",
  6.         "Path": "/sh/start_at_host_data.sh",
  7.         "Args": [],
  8.         "State": {
  9.             "Status": "running",
  10.             "Running": true,
  11.             "Paused": false,
  12.             ……

指定格式：

查看名字、镜像：

  1. # docker inspect --format '{{ .Name }} {{.Image}}' $(docker ps -aq)
  2. /gerrit164 sha256:5bca6530d3ac105a3a98425da0a482bdb42b5d00b36a166bf95604c18566cabd
  3. /es1 sha256:715897d7c63521687493d015c902eb7e9badecd6ad4d0192ce30a594212d28ee

显示挂载路径：

  1. # docker inspect containername -f '{{range .Mounts}}{{printf "%s\t%s\n" .Source .Destination }}{{end}}'
  2. /data/gerrit/docker-config/gerrit/.ssh  /home/gerrit/.ssh
  3. /data/docker/volumes/4872e5fc53a0e543438f68fc3190da72ab91cfe1faeb45507a19fcb3e5ea2e5d/_data     /var/host_data

比较使用awk：

  1. # /data/showMounts.sh gerrit
  2. [{volume b90e60830e3f305b73aa5cbd799b1cd25a2b0e14b5250ff0bcecfc17cfeb5bbe /var/lib/docker/volumes/b90e60830e3f305b73aa5cbd799b1cd25a2b0e14b5250ff0bcecfc17cfeb5bbe/_data /var/gerrit/cache local  true }
