CV-M007: Orphan network definition
Warning Semantic
Why This Matters
A network is defined in the top-level networks section but is not referenced by any service. Orphan network definitions add unnecessary clutter and Docker will create the network even though nothing uses it, wasting resources. Remove unused networks or add them to the appropriate services.
How to Fix
Remove the unused network or add it to a service.
