EKS Addons

EKS Addons can be used with EKS clusters created using Cluster API Provider AWS.

Addons are supported in EKS clusters using Kubernetes v1.18 or greater.

Installing addons

To install an addon you need to declare them by specifying the name, version and optionally how conflicts should be resolved in the AWSManagedControlPlane. For example:

kind: AWSManagedControlPlane
apiVersion: controlplane.cluster.x-k8s.io/v1alpha3
metadata:
  name: "capi-managed-test-control-plane"
spec:
  region: "eu-west-2"
  sshKeyName: "capi-management"
  version: "v1.18.0"
  addons:
    - name: "vpc-cni"
      version: "v1.6.3-eksbuild.1"
      conflictResolution: "overwrite"

Additionally, there is a cluster flavor called eks-managedmachinepool-vpccni that you can use with clusterctl:

clusterctl config cluster my-cluster --kubernetes-version v1.18.0 --flavor eks-managedmachinepool-vpccni > my-cluster.yaml

Updating Addons

To update the version of an addon you need to edit the AWSManagedControlPlane instance and update the version of the addon you want to update. Using the example from the previous section we would do:

...
  addons:
    - name: "vpc-cni"
      version: "v1.7.5-eksbuild.1"
      conflictResolution: "overwrite"
...

Deleting Addons

To delete an addon from a cluster you need to edit the AWSManagedControlPlane instance and remove the entry for the addon you want to delete.

Viewing installed addons

You can see what addons are installed on your EKS cluster by looking in the Status of the AWSManagedControlPlane instance.

Additionally you can run the following command:

clusterawsadm eks addons list-installed -n <<eksclustername>>

Viewing available addons

You can see what addons are available to your EKS cluster by running the following command:

clusterawsadm eks addons list-available -n <<eksclustername>>
