docker helper: version not being obtained #359
Description
Package version (if known): 1.1.0
Describe the bug
With docker 20.10 / docker-compose 1.25.0 (ubuntu 20.04) the docker helper is trying to run 'docker compose' but this command isn't available. It should still be docker-compose in this case.
This causes docker not to be able to start services etc when the helper fails here:
Steps to Reproduce
Bootstrap instance with Docker 20.10 (as packaged in Ubuntu 20.04), bootstrap an instance of ~12 and try to start services.
Expected behavior
services should start
