Just doing a sweep of PRs in this repo, @janitor-of-code are you planning on coming back to this?

FlowFuse/driver-docker#170 also appears to need a little bit more work and there would need to be work in https://github.com/FlowFuse/docker-compose

[janitor-of-code]

yes.
I'm new to all of this so its taking some time and I hadn't much time during the holidays

But I intend to finish the implementation.
Thanks for the reminder on the compose repo, I'll have to look into that
