Docker compose in Juju

[Gayan Gunarathne]

Hi Charles/Samuel,

Thanks for the information.

What I am try to do is to run a docker compose to start docker containers
in a single machine. Still I am not clear how we can use the docker with
Juju.I am following this[1]

Simple I need to use the Juju UI[2] and create my deployment there.Then can
I do the deployment with the docker.How can I select  the docker as a IaaS.
I couldn't find the docker configuration section in environment.yaml.I am
not clear how can I provide the docker as a cloud provider.

Thanks,
Gayan
