Less redundant compose file
Description of the feature
Hi!
YAML support anchors, and compose files can use them as well. This, together with defining the environment
sections as mapping instead of lists, allow having a more compact and less redundant compose file.
Benefits of feature
Set the variables just once; more compact and readable compose file.
