The ansible-bluegreen-docker from decayofmind

Question/Discussion: Is is it not better to use docker compose for updating the services?

Hi Roman,

I came across the docker_service - module in Ansible, which is basically about docker compose. Would it not simplify/easify the concept aka make the transition more seamless? If you split the machines in the inventory in two groups general groups green and blue?

If we theoretically would speak about and inventory that would be in yaml format:

bg_blue:
        hosts:
           10.0.0.1
           10.0.0.3
        vars:
           blue: true

bg_green:
         hosts:
           10.0.0.2
           10.0.0.4
         vars:
             green: true

And move on from there?

Error running molecule

Whenever I run molecule check in the molecule/default directory, I get the following error:
