  "how": {
    "incantation": "When configuring a Cloud Run service, job, or worker pool with an ephemeral disk, use the beta `gcloud run` command with `--add-volume` and `--add-volume-mount` to define and mount it.",
    "examples": [
      "gcloud beta run services update <SERVICE> --execution-environment=gen2 --add-volume=name=<VOLUME_NAME>,type=ephemeral-disk,size=<SIZE> --add-volume-mount=volume=<VOLUME_NAME>,mount-path=<MOUNT_PATH>",
      "gcloud beta run jobs update <JOB> --add-volume=name=<VOLUME_NAME>,type=ephemeral-disk,size=<SIZE> --add-volume-mount=volume=<VOLUME_NAME>,mount-path=<MOUNT_PATH>",
      "gcloud beta run worker-pools update <WORKER_POOL> --add-volume=name=<VOLUME_NAME>,type=ephemeral-disk,size=<SIZE> --add-volume-mount=volume=<VOLUME_NAME>,mount-path=<MOUNT_PATH>"
    ],
    "gotchas": [
      "Availability: In beta.",
      "--add-volume (required): Adds a volume; repeat the flag to add more. Its value must include `type`; `name` is required when `mount-path` is omitted and optional when `mount-path` is specified.",
      "type (required): Set to `ephemeral-disk` for this volume type.",
      "name (required): Volume name; required if `mount-path` is omitted, otherwise optional.",
      "size: Disk space allocated to the volume; docs give `10Gi` or `100G` as examples. The ephemeral disk guide specifies 1Gi–100Gi.",
      "mount-path: Path at which the volume is mounted. For multi-container services, specify it under `--add-volume-mount`.",
      "--add-volume-mount (required): Adds a mount; value must include `volume=<NAME>` and `mount-path=<PATH>`.",
      "volume (required): Name of a volume on the resource to mount.",
      "mount-path (required): Path in the container filesystem where the volume is mounted.",
      "--execution-environment (required): For service ephemeral disks, set to `gen2`; ephemeral disks are only available in the second generation execution environment.",
      "Prerequisite: Install and initialize the gcloud CLI, update components, and enable billing for the project.",
      "Prerequisite: For services, required roles are Cloud Run Developer (`roles/run.developer`) on the service and Service Account User (`roles/iam.serviceAccountUser`) on the service identity.",
      "Prerequisite: Ephemeral disks require the second generation execution environment; each volume must be 1Gi–100Gi.",
      "Applies to volumes with `type=ephemeral-disk`."
