容器“gcr.io/google_containers/pause:0.8.0"中的进程做了什么工作?做? [英] What work does the process in container "gcr.io/google_containers/pause:0.8.0" do?

问题描述

docker选项--net=container:NAME_or_ID的用法我已经很清楚了，我也看过kubernetes的源码，关于如何配置容器使用InfraContainer，所以我认为容器 gcr.io/google_containers/pause:0.8.0 中的唯一工作是暂停"，它永远不会做任何复杂的工作，比如接收"、发送"或路由".

I have known clearly about the usage of the docker option --net=container:NAME_or_ID, I also have read the source code of kubernetes about how to configure the container to use the network of InfraContainer, so I think the only work the process in container gcr.io/google_containers/pause:0.8.0 does is "pause", it will never do any complex work like "receiving", "sending" or "routing".

但我不确定，因为我找不到gcr.io/google_containers/pause:0.8.0的Dockerfile，所以我需要有人清楚关于它告诉我真相，谢谢！

But I am not sure about it because I can not find the Dockerfile of gcr.io/google_containers/pause:0.8.0, so I need someone know clearly about it to tell me the truth, thanks!

推荐答案

pause 休眠，直到它收到 SIGINT 或 SIGTERM.Dockerfile 只是添加了 pause 二进制到一个空容器.

pause sleeps until it receives SIGINT or SIGTERM. The Dockerfile just adds the pause binary to an empty container.
