容器“gcr.io/google_containers/pause：0.8.0”中的过程有哪些功能做？ [英] What work does the process in container "gcr.io/google_containers/pause:0.8.0" do?

问题描述

我已经清楚地知道了docker选项的使用方法 - net = container：NAME_or_ID ，我也已经看过关于如何配置容器的kubernetes的源代码使用 InfraContainer 的网络，所以我认为在容器 gcr.io/google_containers/pause:0.8.0 是暂停，它将永远不会像接收，发送或路由那样复杂的工作。

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

解决方案

Dockerfile是 here ：它只是将暂停二进制文件添加到一个空的容器。

暂停代码是这里：它只是等待直到它收到 SIGINT 或 SIGTERM 。

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".

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!

解决方案

The Dockerfile is here: it just adds pause binary to an empty container.

The pause code is here: it just waits until it receives SIGINT or SIGTERM.
