docker如何查看容器启动命令(已运行的容器)

目录通过docker ps命令通过docker inspect命令总结

eg:

docker ps 查看正在运行的容器:

通过docker ps命令

该命令主要是为了详细展示查看运行时的command参数

docker ps -a –no-trunc | grep container_name   # 通过docker –no-trunc参数来详细展示容器运行命令

通过docker inspect命令

使用docker inspect，但是docker inspect打印的是json文件，需要挑选字段查看，容器的参数信息都能从json文件中解析出来。

1，在容器外部，物理机上，可以用下面命令

docker inspect <container_name>   # 可以是container_name或者container_id

eg:

[root@128 ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 547880f43cf1 mysql:8.0.31 “docker-entrypoint.s…” 15 minutes ago Up 15 minutes 33060/tcp, 0.0.0.0:3301->3306/tcp,

如上所示，这个是我这547880f43cf1 容器的详细信息

然后可以定制化输出上面的信息：显示上面内容的某一部分信息

docker inspect –format={{.NetworkSettings.Networks.bridge.IPAddress}} <container_name> # format是go语言的template，还有其他的用法 docker inspect –format={{.Mounts}} <container_name> docker inspect –format={{.HostConfig.Binds}} <container_name> docker inspect –format={{.HostConfig.PortBindings}} <container_name>

eg: 还可以将上面的修改为别的内容，我这边关注file和port两个

[root@128 ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 547880f43cf1 mysql:8.0.31 “docker-entrypoint.s…” 18 minutes ago Up 18 minutes 33060/tcp, 0.0.0.0:3301->3306/tcp, :::3301->3306/tcp mysql-8.0.31 e02f22dc442c mysql:5.7 “docker-entrypoint.s…” 25 hours ago Up 22 minutes 0.0.0.0:3306->3306/tcp, :::3306->3306/tcp, 33060/tcp mysql [root@128 ~]# docker inspect –format={{.Mounts}} 547880f43cf1 [{bind /mydata/mysql-8.0.31/log /var/log/mysql true rprivate} {bind /mydata/mysql-8.0.31/data /var/lib/mysql true rprivate}] [root@128 ~]# docker inspect –format={{.NetworkSettings.Networks.bridge.IPAddress}} 547880f43cf1 172.17.0.2 [root@128 ~]# docker inspect –format={{.HostConfig.Binds}} 547880f43cf1 [/mydata/mysql-8.0.31/log:/var/log/mysql /mydata/mysql-8.0.31/data:/var/lib/mysql] [root@128 ~]# docker inspect –format={{.HostConfig.PortBindings}} 547880f43cf1 map[3306/tcp:[{ 3301}]] [root@128 ~]#
