For Cloud Composer environments in versions composer-1.*.*-airflow-*.*.*, this field is applicable only when `use_ip_aliases` is true. Set to blank to have GKE choose a range with the default size. Set to /netmask (e.g. `/14`) to have GKE choose a range with a specific netmask. Set to a [CIDR](https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing) notation (e.g. `10.96.0.0/14`) from the RFC-1918 private networks (e.g. `10.0.0.0/8`, `172.16.0.0/12`, `192.168.0.0/16`) to pick a specific range to use. Specify `cluster_secondary_range_name` or `cluster_ipv4_cidr_block` but not both.
+        "clusterSecondaryRangeName": "A String", # Optional. The name of the cluster's secondary range used to allocate IP addresses to pods. Specify either `cluster_secondary_range_name` or `cluster_ipv4_cidr_block` but not both. For Cloud Composer environments in versions composer-1.*.*-airflow-*.*.*, this field is applicable only when `use_ip_aliases` is true.

         "useIpAliases": True or False, # Optional. Whether or not to enable Alias IPs in the GKE cluster. If `true`, a VPC-native cluster is created.

       "location": "A String", # Optional. The Compute Engine [zone](/compute/docs/regions-zones) in which to deploy the VMs used to run the Apache Airflow software, specified as a [relative resource name](/apis/design/resource_names#relative_resource_name). For example: "projects/{projectId}/zones/{zoneId}". This `location` must belong to the enclosing environment's project and location. If both this field and `nodeConfig.machineType` are specified, `nodeConfig.machineType` must belong to this `location`; if both are unspecified, the service will pick a zone in the Compute Engine region corresponding to the Cloud Composer location, and propagate that choice to both fields. If only one field (`location` or `nodeConfig.machineType`) is specified, the location information from the specified field will be propagated to the unspecified field. This field is supported for Cloud Composer environments in versions composer-1.*.*-airflow-*.*.*.
