Docker Compose
Docker Compose does not support circular extends references
Circular references with `extends` are not supported
Docker Compose found a circular reference between services that use extends, so the configuration graph cannot be resolved safely.
Observed message
Circular references with `extends` are not supported
Why it happens
- Two or more services extend one another directly or indirectly.
- A shared base-service pattern introduced a recursive reference.
- The Compose file inheritance graph is no longer acyclic.
How to fix it
- Break the recursive extends chain so inheritance flows in one direction only.
- Extract shared settings into a neutral base service or extension pattern that does not recurse.
- Re-validate the Compose file after simplifying the service inheritance structure.
