Configure Kubernetes control plane to operate over IPv6
Big picture​
If you have IPv6 connectivity between your nodes and workloads, you may also want to configure the Kubernetes control plane to operate over IPv6, instead of IPv4.
How to​
To configure Kubernetes components for IPv6 only, set the following flags.
| Component | Flag | Value/Content |
|---|---|---|
| kube-apiserver | --bind-address or --insecure-bind-address | Set to the appropriate IPv6 address or :: for all IPv6 addresses on the host. |
--advertise-address | Set to the IPv6 address that nodes should use to access the kube-apiserver. | |
| kube-controller-manager | --master | Set with the IPv6 address where the kube-apiserver can be accessed. |
| kube-scheduler | --master | Set with the IPv6 address where the kube-apiserver can be accessed. |
| kubelet | --address | Set to the appropriate IPv6 address or :: for all IPv6 addresses. |
--cluster-dns | Set to the IPv6 address that will be used for the service DNS; this must be in the range used for --service-cluster-ip-range. | |
--node-ip | Set to the IPv6 address of the node. | |
| kube-proxy | --bind-address | Set to the appropriate IPv6 address or :: for all IPv6 addresses on the host. |
--master | Set with the IPv6 address where the kube-apiserver can be accessed. |
