docker怎么查看容器启动命令(docker,开发技术)

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:

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

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