+
+The `resources` field lets you configure CPU and memory for the build job container. Values use standard Kubernetes resource units (e.g., `"500m"` for CPU, `"1Gi"` for memory).
+
+**Precedence:** Per-service `resources` in lifecycle.yaml take priority over values set in `global_config`. If neither is set, built-in defaults are used.
