CV-M010: depends_on service_healthy without healthcheck
Error Semantic
Why This Matters
A service uses depends_on with condition: service_healthy, but the target service does not define a healthcheck. Docker Compose will wait indefinitely for the target to become healthy, effectively hanging the startup. Either add a healthcheck to the target service or change the condition to service_started.
How to Fix
Add a healthcheck to the target service or use service_started condition.
