    "incantation": "When creating a node pool with an additional network interface, set `stack-type` to the required IP stack: `ipv4`, `ipv4-ipv6`, or `ipv6`.",
    "examples": [
      "gcloud container node-pools create <POOL_NAME> --cluster=<CLUSTER_NAME> --location=<LOCATION> --additional-node-network=network=<NETWORK_NAME>,subnetwork=<SUBNET_NAME>,stack-type=<ipv4|ipv4-ipv6|ipv6>",
      "gcloud container node-pools create <POOL_NAME> --cluster=<CLUSTER_NAME> --location=<LOCATION> --additional-node-network network=<NETWORK_NAME>,subnetwork=<SUBNET_NAME>,stack-type=ipv6"
    ],
    "gotchas": [
      "<POOL_NAME> (required): Name of the new node pool.",
      "--cluster (required): Existing cluster to which the node pool is added.",
      "--location (required): Cluster location; specify a zone or region.",
      "--additional-node-network: Attach an additional network interface to each node; may be specified up to 7 times in the CLI reference.",
      "network (required): Network to attach to the new interface.",
      "subnetwork (required): Subnetwork to attach to the new interface.",
      "stack-type: Interface IP stack type: `ipv4`, `ipv4-ipv6`, or `ipv6`. The docs do not state these values are mutually exclusive beyond requiring one value for this parameter.",
      "Prerequisite: Create the node pool in an existing cluster. Multi-network setup requires a cluster with multi-networking enabled; the docs say to enable it only when Dataplane V2 is enabled.",
      "Prerequisite: Prepare the additional VPC and subnet. The selected stack type must be compatible with the subnet: IPv4-only permits `ipv4`, dual-stack permits all three, and IPv6-only permits `ipv6`.",
      "The stack-type choices stated are `ipv4`, `ipv4-ipv6`, or `ipv6`."

  "before": "Before this release, `gcloud container node-pools create` did not provide the `stack-type` option for `--additional-node-network`.",
