在docker中运行chroot [英] run chroot within docker

问题描述

我有一个商业应用程序，它在chroot环境中提供：启动脚本正在制作chroot，然后启动exe。

I've a commercial app, that is shipped in a chroot environment : the startup script is making the chroot, and starting the exe.

该应用程序很漂亮复杂，并且出于支持目的，我不想更改所有环境。

The App is pretty complex, and also for support purposes, I don't want to change the all environment.

是否可以运行chroot，并在docker中启动服务？还是这两个不兼容？

Is it possible to run chroot, and start the service in docker ? Or are the two incompatible ?

推荐答案

可以在容器内制作chroot ...但是，如 在Docker容器内解除引导，您可能需要以特权模式运行。

It is possible to make a chroot inside a container... but, as mentioned in "debootstrap inside a docker container", you might need to run with the privileged mode.

docker run --privileged

默认情况下，Docker容器是无特权的，例如，不能在Docker容器内运行Docker守护程序。

这是因为默认情况下，不允许容器访问任何设备，但是授予特权容器访问所有设备的权限。

By default, Docker containers are "unprivileged" and cannot, for example, run a Docker daemon inside a Docker container.
This is because by default a container is not allowed to access any devices, but a "privileged" container is given access to all devices.

关于请求docker支持特权操作的巨大讨论。
到目前为止，
，它不会发生。

There was a huge discussion for requesting docker to support privileged operations.
So far, it is not happening.
