service Ipv4Cidr
Parameters
value
The CIDR block to assign Kubernetes pod and service IP addresses from. If you don't specify a block, Kubernetes assigns addresses from either the 10.100.0.0/16 or 172.20.0.0/16 CIDR blocks. We recommend that you specify a block that does not overlap with resources in other networks that are peered or connected to your VPC. You can only specify a custom CIDR block when you create a cluster, changing this value will force a new cluster to be created. The block must meet the following requirements:
Within one of the following private IP address blocks: 10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16.
Doesn't overlap with any CIDR block assigned to the VPC that you selected for VPC.
Between /24 and /12.
