Docker support implementation was started by Goran Cetusic during the Google Summer Of Code 2015 and finished by the GNS3 core team. Also, we would like to thank Bernhard Ehlers and Aj Nouri who contributed a lot of their time to test it.
We also have some documentation about using a Docker container in GNS3 that can be found on https://gns3.com/support/docs/docker-2
