在Docker容器内的debootstrap [英] debootstrap inside a docker container

问题描述

这是我的问题：我想在docker容器内部建立一个chroot环境。问题是debootstrap无法运行，因为它无法在chroot中挂载proc：

Here's my problem: I want to build a chroot environment inside a docker container. The problem is that debootstrap cannot run, because it cannot mount proc in the chroot:

W：尝试运行失败：chroot / var / chroot mount -t proc proc / proc

（在日志中，问题证明是： mount：permission denied ）

(in the log the problem turns out to be: mount: permission denied)

如果我运行--privileged 容器，它（当然）工作...
我真的很希望在Dockerfile中引导chroot（更清洁）。有没有办法让它工作？

If I run --privileged the container, it (of course) works... I'd really really really like to debootstrap the chroot in the Dockerfile (much much cleaner). Is there a way I can get it to work?

非常感谢！

推荐答案

不，目前不可能。

问题＃1916 （涉及在 docker build 期间运行特权操作）仍然是一个开放的问题。在添加命令行标志和 RUNP 命令的一点上进行了讨论，但都没有实现这些命令。

Issue #1916 (which concerns running privileged operations during docker build) is still an open issue. There was discussion at one point of adding a command-line flag and RUNP command but neither of these have been implemented.
