docker怎么查看容器启动命令

时间:2024-3-6 14:38     作者:韩俊     分类: Linux


本篇内容介绍了“docker怎么查看容器启动命令”的有关知识,在实际案例的操作过程中,不少人都会遇到这样的困境,接下来就让小编带领大家学习一下如何处理这些情况吧!希望大家仔细阅读,能够学有所成!

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

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
