I guess MY_DOMAIN should be $MY_DOMAIN

[DoTheEvo]

one would think so, but test it...
change it to $MY_DOMAIN or ${MY_DOMAIN}
exec in to container using ctop and run printenv
only plain works...

I guess it is some substitution or short form
and in full it should be or whatever

environment:
  - MY_DOMAIN=$MY_DOMAIN

I might have know why and how it worked few months back, or I might have not... i dont remember now and quick google was not a success
