Mininet inside a Docker container

A Docker image for Mininet forked from iwaseyusuke/docker-mininet to include Python3 and Wireshark, among other utilities.

Usage

Mininet Docker image can be built as docker build -t mininet . and run as

docker run -it --rm --privileged -e DISPLAY \
             -v /tmp/.X11-unix:/tmp/.X11-unix \
             -v /lib/modules:/lib/modules \
             -v $(pwd):/data \
             mininet

Contents of the current working directory are then available in /data.

Open X Window applications in containers

If you could not open xterm or other X Window applications, or faced to the following error message:

root@26f36691a400:~# xterm
No protocol specified
Warning: This program is an suid-root program or is being run by the root user.
The full text of the error or warning message cannot be safely formatted
in this environment. You may get a more descriptive message by running the
program as a non-root user or by removing the suid bit on the executable.
xterm: Xt error: Can't open display: %s

Please, add root user to the local access control list of xhost on your "Docker host" (not on your containers).
