K8s Installers and Distributions

Tested installers and distributions

The table below is not comprehensive. Antrea should work with most K8s installers and distributions. The table refers to specific version combinations which are known to work and have been tested, but support is not limited to that list. Each Antrea version supports multiple K8s minor versions, and installers / distributions based on any one of these K8s versions should work with that Antrea version.

Installer-specific instructions


When running kubeadm init to create a cluster, you need to provide a range of IP addresses for the Pod network using --pod-network-cidr. By default, a /24 subnet will be allocated out of the CIDR to every Node which joins the cluster, so make sure you use a large enough CIDR to accommodate the number of Nodes you want. Once the cluster has been created, this CIDR cannot be changed.


When creating a workload cluster, set the network plugin to none.


When creating a cluster, run K3s with the following options:

  • --flannel-backend=none, which lets you run the CNI of your choice
  • --disable-network-policy, to disable the K3s NetworkPolicy controller


When creating a cluster, run Kops with --networking cni, to enable CNI for the cluster without deploying a specific network plugin.


To deploy Antrea on Kind, please follow these steps.
