  postgrest:
    image: postgrest/postgrest:v12.2.8
    environment:
      PGRST_DB_ANON_ROLE: anon
      PGRST_DB_URI: postgres://authenticator:${PGRST_AUTHENTICATOR_PASS:?}@postgres:5432/app
    networks:
      - default
      - db_default

If you're self-hosting Postgres don't forget this part:

app/compose.yaml

networks:
  db_default:
    external: true

Optionally in development, increase the log level:

app/compose.override.yaml

  postgrest:
    environment:
      PGRST_LOG_LEVEL: debug
