docker inpsect

官方地址[https://docs.docker.com/engine/reference/commandline/inspect/#examples}(https://docs.docker.com/engine/reference/commandline/inspect/#examples)
可以看看比较优秀的相关博客https://www.cnblogs.com/kevingrace/p/6424476.html

1. 查看容器的Pid
   docker inspect --format {{.State.Pid}} <container_name_or_ID>
2. 查看容器的日志
   docker inspect --format='{{.LogPath}}' $INSTANCE_ID
3. Get an instance’s IP address
   docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $INSTANCE_ID
4. Get an instance’s image name
   docker inspect --format='{{.Config.Image}}' $INSTANCE_ID
5. List all port bindings列出所有绑定的端口
   docker inspect --format='{{range $p, $conf := .NetworkSettings.Ports}} {{$p}} -> {{(index $conf 0).HostPort}} {{end}}' $INSTANCE_ID
6. Find a specific port mapping查看某个映射到主机的端口
   docker inspect --format='{{(index (index .NetworkSettings.Ports "8787/tcp") 0).HostPort}}' $INSTANCE_ID
7. json格式的Config
   docker inspect --format='{{json .Config}}' $INSTANCE_ID
   docker inspect ID
   顶级的大概有这几大块，

Id
Created
Path
Args
State
Image
ResolvConfPath
HostnamePath
HostsPath
LogPath
Name
RestartCount
Driver
Platform
MountLabel
ProcessLabel
AppArmorProfile
ExecIDs
HostConfig
GraphDriver
Mounts
Config
NetworkSettings

以下是详细的参考
