A proof of concept [user mode linux](https://en.wikipedia.org/wiki/User-mode_Linux)
|
||
|
|
Docker image. This builds a simply configured kernel and sets up an [Alpine Linux](https://alpinelinux.org)
|
||
|
|
userland for it. It has fully working networking via slirp.
|
||
|
|
|
||
|
|
This runs an entire Linux kernel as a userspace process inside a docker container.
|
||
|
|
Anything you can do as root in a linux kernel, you can do inside this user mode
|
||
|
|
Linux process. The root inside this user mode Linux kernel has significanly more
|
||
|
|
power than root outside of the kernel, but it cannot affect the host kernel.
|
||
|
|
|
||
|
|
To build:
|
||
|
|
|
||
|
|
```
|
||
|
|
docker build -t xena/docker-uml .
|
||
|
|
```
|
||
|
|
|
||
|
|
To run:
|
||
|
|
|
||
|
|
```
|
||
|
|
docker run --rm -it xena/docker-uml
|
||
|
|
```
