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. |
