如何在Docker中使用.bashrc作为root [英] How to .bashrc for root in Docker

问题描述

我想给（ centos：6 ）Docker容器中的root用户一个 .bashrc 。但是，当我运行容器时，发现 .bashrc 尚未得到。可以做到吗？

I want to give my root user in a (centos:6) Docker container a .bashrc. However, when I run my container, I find that the .bashrc has not been sourced. Can this be done?

我的构建命令：

...
RUN touch .bashrc
RUN echo "iptables -t nat -A OUTPUT -d hostA -p tcp --dport 3306 -j DNAT --to hostB" >> .bashrc
...

我的运行命令：

docker run -it --cap-add=NET_ADMIN myImage /bin/bash

推荐答案

原来是我错误地添加了文件。它应该是 /root/.bashrc ，而不只是 .bashrc 。将文件添加到正确的位置，不需要运行命令或CMD。

Turns out I was adding the file incorrectly. It should be /root/.bashrc rather than just .bashrc. With the file added in the correct place, no run command or CMD is required.

Build

...
ADD iptables /iptables
RUN touch /root/.bashrc \
 && cat iptables >> /root/.bashrc
...

运行

docker run -it --cap-add=NET_ADMIN myImage /bin/bash
