KubernetesNetworkConfigResponse - Amazon EKS

KubernetesNetworkConfigResponse

The Kubernetes network configuration for the cluster. The response contains a value for serviceIpv6Cidr or serviceIpv4Cidr, but not both.

Contents

ipFamily

The IP family used to assign Kubernetes pod and service IP addresses. The IP family is always ipv4, unless you have a 1.21 or later cluster running version 1.10.1 or later of the Amazon VPC CNI add-on and specified ipv6 when you created the cluster.

Type: String

Valid Values: ipv4 | ipv6

Required: No

serviceIpv4Cidr

The CIDR block that Kubernetes pod and service IP addresses are assigned from. Kubernetes assigns addresses from an IPv4 CIDR block assigned to a subnet that the node is in. If you didn't specify a CIDR block when you created the cluster, then Kubernetes assigns addresses from either the 10.100.0.0/16 or 172.20.0.0/16 CIDR blocks. If this was specified, then it was specified when the cluster was created and it can't be changed.

Type: String

Required: No

serviceIpv6Cidr

The CIDR block that Kubernetes pod and service IP addresses are assigned from if you created a 1.21 or later cluster with version 1.10.1 or later of the Amazon VPC CNI add-on and specified ipv6 for ipFamily when you created the cluster. Kubernetes assigns service addresses from the unique local address range (fc00::/7) because you can't specify a custom IPv6 CIDR block when you create the cluster.

Type: String

Required: No
