每个容器有独立的PID名空间, 容器的生命周期和其PID1进程一致 利用docker exec可以进入到容器的名空间中启动进程 此外,自从Docker 1.5之后,docker run命令引入了--pid=host参数来支持使用宿主机PID名空间来启动容器进程,这样可以方便的实现容器内应用和宿主机应用之间的交互:比如利用容器中的工具监控和调试宿主机进程。
操作系统的PID1进程是init进程,以守护进程方式运行,是所有其他进程的祖先,具有完整的进程生命周期管理能力。在Docker容器中,PID1进程是启动进程,它也会负责容器内部进程管理的工作。而这也将导致进程管理在Docker容器内部和完整操作系统上的不同。 进程信号处理 信号是Unix/Linux中进程间异步通信机制。Docker提供了两个...

There's a known bug with child process reaping in Docker containers. Here's an article that explains in some details what this issue is about: http://blog.phusion.nl/2015/01/20/docker-and-the-pid-1-zombie-reaping-problem/ My question is if it would be worth to integrate a small init...

1. 运行"myredis:shell"镜像,我们可以发现它的启动进程(PID1)是/bin/sh -c "/usr/bin/redis-server",并且它创建了一个子进程/usr/bin/redis-server *:6379。 docker@default:~$ docker run -d --name myredis myredis:shell 49f7fc37f4b7cf1ed7f5296537a93b2ad23b1b6686a05e5c7e40e9a2b2d3665e ...

Sends a signal to the main process (PID 1) in a container. By default, sends aSIGKILL, which will cause the container to exit immediately. Alternatively, the signal can be specified with the-sargument. The container ID is returned.
Problems with PID 1 in Docker The command listed as "CMD" in the docker image properties or being given as docker-run argument will become the PID-1 of a new container. Actually it takes the place that would traditionally be used by the /sbin/init process which has a special functionality...
