Calico VXLAN Addon

It is possible to use CNI plugins that are not directly supported by the KubeOne. Here’s an example for Calico.

Example AWS kubeone config

apiVersion: kubeone.k8c.io/v1beta2
kind: KubeOneCluster

versions:
  kubernetes: 1.25.6

cloudProvider:
  aws: {}

clusterNetwork:
  cni:
    external: {}

addons:
  enable: true
  addons:
    - name: calico-vxlan
      params:
        MTU: "0" # auto-detect MTU

You can use the following MTU values depending on your provider:

• MTU: "" — auto-detect MTU
• MTU: "8951" — use this if provider is AWS
• MTU: "1400" — use this if provider is OpenStack
• MTU: "1410" — use this if provider is GCE
