问题描述
通常，docker容器是使用用户 root 来运行的。我想使用不同的用户，这是使用docker的USER指令没问题的。但这个用户应该能够在容器内使用 sudo 。此命令缺失。
Normally, docker containers are run using the user root. I'd like to use a different user, which is no problem using docker's USER directive. But this user should be able to use sudo inside the container. This command is missing.
这是一个简单的Docker文件，用于此目的：
Here's a simple Dockerfile for this purpose:
FROM ubuntu:12.04
RUN useradd docker && echo "docker:docker" | chpasswd
RUN mkdir -p /home/docker && chown -R docker:docker /home/docker
USER docker
CMD /bin/bash
运行此容器，我用用户'docker'登录。当我尝试使用sudo时，没有找到该命令。所以我试图使用
Running this container, I get logged in with user 'docker'. When I try to use sudo, the command isn't found. So I tried to install the sudo package inside my Dockerfile using
RUN apt-get install sudo
这导致无法找到包sudo
我不知道如何管理这个。有什么建议么？ Thx很多！
I've no idea how to manage this. Any suggestions? Thx a lot!
推荐答案
刚刚得到它。正如Regan指出的，我不得不将用户添加到sudoers组。但主要原因是我忘记更新存储库缓存，所以apt-get找不到sudo包。它现在正在工作以下是完成的代码：
Just got it. As regan pointed out, I had to add the user to the sudoers group. But the main reason was I'd forgotten to update the repositories cache, so apt-get couldn't find the sudo package. It's working now. Here's the completed code:
FROM ubuntu:12.04
RUN apt-get update && \
apt-get -y install sudo
RUN useradd -m docker && echo "docker:docker" | chpasswd && adduser docker sudo
USER docker
CMD /bin/bash
