Docker MaaS

This repo contains a Dockerfile and an ansible playbook to build a Docker image with Canonical's MaaS. The build procedure is a little different from usual Dockerfiles, because we have to start the container in privileged mode to finish building.

To build the container, type

make build

This will build a first docker image, then run that image in --privileged mode to finish the installation. To run the image, create a persistent volume:

make persistent_data

Then start the image

make run_persistent

If you want to boot pysical nodes with MaaS create a docker network that contains a physical interface. Assuming your physical network is on the 192.168.1.0/24 subnet, create a new docker network with

docker network create --subnet=192.168.1.0/24 net1

The network net1 will then show up in the list of docker networks:

$ docker network ls
NETWORK ID          NAME                    DRIVER
c93f2f6e09df        bridge                  bridge              
f1013ec4aa62        host                    host                
094a5738492a        net1                    bridge              
a9c220157a01        none                    null                
9ff0cc43cec6        sentrycompose_default   bridge  

and in the list of bridges:

$ brctl show
bridge name	bridge id		STP enabled	interfaces
br-094a5738492a		8000.0242ea91311f	no		eth1

You can add physical devices (e.g. eth0) by typing

brctl addif br-094a5738492a eth0

Now stop the running container and start a new container inside the newly created docker container:

make rm # stops and removes container
make run_persistent -e NET=net1

You should be able to deploy machines in MaaS now.
