vagrant-inside-docker
Running vagrant inside a docker container. We use a small box based on OpenWRT 15.05 as a lightweight distro (7MB).
You need vagrant kernel modules on the host.
To quote the FOSDEM2017 presentation on “Running virtual machines in containers”:
https://fosdem.org/2017/schedule/event/virtcontainers/
The idea of running virtual machines inside containers is surprisingly old andwas used due to several reasons. They include willingness to run VM-s incontainer orchestration engines like Kubernetes or Borg, or packaging IaaScloud software like OpenStack in containers. In this presentation, I am goingto describe these use cases and two main different approaches of containerizingVM-s - putting every qemu(-kvm) process in a separate container (like Borg orRancher OS are doing) and putting libvirtd process in container (like OpenStackKolla or Stackanetes are doing)
Just launch ./run.sh
You can also run it as a oneliner:
docker run --privileged -v /dev/vboxdrv:/dev/vboxdrv -v /dev/vboxnetctl:/dev/vboxnetctl -it zoobab/vagrant-inside-docker:latest /bin/bash -c "vagrant up && vagrant ssh"
Everybody love screenshots:

docker stop takes time to stop the running container, or never stops it :-)
