Vmck

Vmck is a virtual machine service that runs QEMU and Docker images in a Nomad cluster.

It can be used as a provider for Vagrant:

vagrant plugin install vagrant-vmck
curl -OL <https://github.com/mgax/vagrant-vmck/raw/master/example_box/Vagrantfile>
vagrant up
vagrant ssh

And it has its own CLI:

pipenv run ./manage.py createjob
pipenv run ./manage.py ssh 1
pipenv run ./manage.py kill 1

Installation

Using docker

docker run --detach --restart always \\
  --name cluster \\
  --volume /opt/cluster/var:/opt/cluster/var \\
  --volume /opt/vmck/var:/opt/vmck/var \\
  --volume /var/run/docker.sock:/var/run/docker.sock:ro \\
  --privileged \\
  --net host \\
  --env NOMAD_CLIENT_INTERFACE=wg0 \\
  --env HOSTNAME=127.0.0.1 \\
  --env SECRET_KEY=foo \\
  mgax/vmck

Here you can add different --env options with arguments matching {root}/vmck/settings.py and {root}/vmck/base_settings.py to suit your preferences.

Then go to consul (http://localhost:8500/ui/dc1/services) and wait for the health check lights to turn green.

Running locally

Needs a Nomad instance alongside Consul(liquidinvestigations/cluster is easy to set-up and has both Nomad and Consul)
If you are using the above mentioned cluster you can skip this step if not add the following to your .env file:

SECRET_KEY=change_me
CONSUL_URL=your_consul_url
NOMAD_URL=your_nomad_url

By default the docker backend is selected. You can choose qemu by adding BACKEND=qemu to your .env file
