Docker是一个开源的应用容器引擎,让开发者可以打包他们的应用以及依赖包到一个可移植的容器中,然后发布到任何流行的Linux机器上,下面这篇文章主要给大家介绍了关于docker如何查看容器启动命令(已运行的容器)的相关资料,需要的朋友可以参考下
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
# 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,

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}}' # format是go语言的template，还有其他的用法 docker inspect --format='{{.Mounts}}' docker inspect --format='{{.HostConfig.Binds}}' docker inspect --format='{{.HostConfig.PortBindings}}' 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
