Class IPAllocationPolicy (1.17.5) 

IPAllocationPolicy(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Configuration for controlling how IPs are allocated in the GKE cluster.

Attributes
Name Description
use_ip_aliases bool
Optional. Whether or not to enable Alias IPs in the GKE cluster. If true, a VPC-native cluster is created. This field is only supported for Cloud Composer environments in versions composer-1.\ *.*-airflow-*.*.*. Environments in newer versions always use VPC-native GKE clusters.
cluster_secondary_range_name str
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.
services_secondary_range_name str
Optional. The name of the services' secondary range used to allocate IP addresses to the cluster. Specify either services_secondary_range_name or services_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.
cluster_ipv4_cidr_block str
Optional. The IP address range used to allocate IP addresses to pods in the cluster. 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 __ 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.
services_ipv4_cidr_block str
Optional. The IP address range of the services IP addresses in this cluster. 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 __ 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 services_secondary_range_name or services_ipv4_cidr_block but not both.
