Reproduce bug with DockerCan and Docker v29

This is aimed to show an intermittent bug when using the DockerCan network plugin together with Docker v29.

Instructions for Running

This is only available on Linux.

Install DockerCan

To run this, you need to install can-utils and DockerCan first:

can-utils can be installed with apt:

sudo apt install can-utils

Download the latest version of DockerCAN from https://releases.remotivelabs.com/#docker_can/

mkdir dockercan
tar xvf dockercan-VERSION.tar.gz -C dockercan
cd dockercan
make
cd ..
rm -rf dockercan

Run the examples

Just run up.sh to create the networks and run the containers. It doesn't fail every time, so you might need to to try it a few times.

Use down.sh to tear down everything between runs.

Example

$ ./up.sh
