DESCRIPTION
    Register an Attached cluster.

EXAMPLES
    Register a cluster to a fleet.

    To register a cluster with a private OIDC issuer, run:

        $ gcloud container attached clusters register my-cluster \
            --location=us-west1 --platform-version=PLATFORM_VERSION \
            --fleet-project=FLEET_PROJECT_NUM --distribution=DISTRIBUTION \
            --context=CLUSTER_CONTEXT --has-private-issuer

    To register a cluster with a public OIDC issuer, run:

        $ gcloud container attached clusters register my-cluster \
            --location=us-west1 --platform-version=PLATFORM_VERSION \
            --fleet-project=FLEET_PROJECT_NUM --distribution=DISTRIBUTION \
            --context=CLUSTER_CONTEXT --issuer-url=https://ISSUER_URL

    To specify a kubeconfig file, run:

        $ gcloud container attached clusters register my-cluster \
            --location=us-west1 --platform-version=PLATFORM_VERSION \
            --fleet-project=FLEET_PROJECT_NUM --distribution=DISTRIBUTION \
            --context=CLUSTER_CONTEXT --has-private-issuer \
            --kubeconfig=KUBECONFIG_PATH

    To register and set cluster admin users, run:

        $ gcloud container attached clusters register my-cluster \
            --location=us-west1 --platform-version=PLATFORM_VERSION \
            --fleet-project=FLEET_PROJECT_NUM --distribution=DISTRIBUTION \
            --context=CLUSTER_CONTEXT --issuer-url=https://ISSUER_URL \
            --admin-users=USER1,USER2

POSITIONAL ARGUMENTS
     Cluster resource - cluster to register. The arguments in this group can be
     used to specify the attributes of this resource. (NOTE) Some attributes
     are not given arguments in this group but can be set in other ways. To set
     the project attribute:
      ◆ provide the argument cluster on the command line with a fully
        specified name;
      ◆ provide the argument --project on the command line;
      ◆ set the property core/project.

     This must be specified.

       CLUSTER
          ID of the cluster or fully qualified identifier for the cluster. To
          set the cluster attribute:
          ▸ provide the argument cluster on the command line.

          This positional argument must be specified if any of the other
          arguments in this group are specified.

       --location=LOCATION
          Google Cloud location for the cluster. To set the location attribute:
          ▸ provide the argument cluster on the command line with a fully
            specified name;
          ▸ provide the argument --location on the command line;
          ▸ set the property container_attached/location.

REQUIRED FLAGS
     --distribution=DISTRIBUTION
        Set the base platform type of the cluster to attach.

        Examples:

            $ gcloud container attached clusters register --distribution=aks
            $ gcloud container attached clusters register --distribution=eks

     --fleet-project=FLEET_PROJECT
        ID or number of the Fleet host project where the cluster is registered.

     --platform-version=PLATFORM_VERSION
        Platform version to use for the cluster.

        To retrieve a list of valid versions, run:

            $ gcloud alpha container attached get-server-config \
                --location=LOCATION

        Replace LOCATION with the target Google Cloud location for the cluster.

     kubectl config

     This must be specified.

       --context=CONTEXT
          Context to use in the kubeconfig.

          This flag argument must be specified if any of the other arguments in
          this group are specified.

       --kubeconfig=KUBECONFIG
          Path to the kubeconfig file.

          If not provided, the default at ~/.kube/config will be used.

     OIDC config

     Exactly one of these must be specified:

       --has-private-issuer
          Indicates no publicly routable OIDC discovery endpoint exists for the
          Kubernetes service account token issuer.

          If this flag is set, gcloud will read the issuer URL and JWKs from
          the cluster's api server.

       --issuer-url=ISSUER_URL
          Issuer url of the cluster to attach.

OPTIONAL FLAGS
     --admin-users=[USER,...]
        Users that can perform operations as a cluster administrator.

        There is no way to completely remove admin users after setting.

     --annotations=ANNOTATION,[ANNOTATION,...]
        Annotations for the cluster.

     --description=DESCRIPTION
        Description for the cluster.

     --enable-managed-prometheus
        Enable managed collection for Managed Service for Prometheus.

     --logging=COMPONENT,[COMPONENT,...]
        Set the components that have logging enabled.

        Examples:

            $ gcloud container attached clusters register --logging=SYSTEM
            $ gcloud container attached clusters register \
                --logging=SYSTEM,WORKLOAD
            $ gcloud container attached clusters register --logging=NONE

        COMPONENT must be one of: NONE, SYSTEM, WORKLOAD.

     --validate-only
        Validate the cluster to create, but don't actually perform it.
