chore(compose): remove container_name entries from services in compos…

[igorcampos-dev]

…e.yaml

Summary by CodeRabbit

• Chores
  • Standardized Docker Compose setups by removing explicit container names across examples; containers now use default auto-generated names.
  • Service-to-service communication is unaffected (service hostnames remain the same).
  • Reduces name collisions, enabling multiple project instances to run in parallel more easily.
  • If you relied on fixed container names in scripts or commands, update them to use service names or the auto-generated container names.

Walkthrough

Removed explicit container_name properties from services across three compose.yaml files (spring-kafka-example, spring-keycloak-example, spring-prometheus-grafana-example). No other service configurations were changed.

Changes

Kafka example compose cleanup spring-kafka-example/compose.yaml	Removed container_name from services: app, kafka, kafka-init.
Keycloak example compose cleanup spring-keycloak-example/compose.yaml	Removed container_name from services: app, keycloak, keycloak-database.
Prometheus/Grafana example compose cleanup spring-prometheus-grafana-example/compose.yaml	Removed container_name from services: app, prometheus, grafana.
