寻找 Docker 容器进程?(从主持人的角度来看) [英] Finding Docker container processes? (from host point of view)
问题描述
我正在对 docker 和容器进行一些测试,我想知道:
I am doing some tests on docker and containers and I was wondering:
是否有一种方法可以用来从主机的角度通过名称或 ID 查找与 docker 容器关联的所有进程.
Is there a method I can use to find all process associated with a docker container by its name or ID from the host point of view.
毕竟,容器归根结底是一组虚拟化进程.
After all, at the end of the day a container is a set of virtualized processes.
推荐答案
您可以使用 docker top
命令.此命令列出在您的容器中运行的所有进程.
You can use docker top
command.
This command lists all processes running within your container.
例如,此命令在我的盒子上的单个进程容器上显示:
For instance this command on a single process container on my box displays:
UID PID PPID C STIME TTY TIME CMD
root 14097 13930 0 23:17 pts/6 00:00:00 /bin/bash
其他人提到的所有方法都可以使用,但这个应该是最简单的.
All methods mentioned by others are also possible to use but this one should be easiest.
更新:
要简单地获取容器内的主进程 ID,请使用以下命令:
To simply get the main process id within the container use this command:
docker inspect -f '{{.State.Pid}}' <container id>
