Alfresco Content Services Community Edition Helm Deployment with AWS EKS

Our company are in the throes of purchasing Alfresco Content Services Enterprise and this will be deployed in our production environment.

Before we do so, I have been tasked with installing a proof of concept (PoC) version in our test AWS environment so ithought the Community Edition would be a good place to start.

The chosen method therefore being Helm with AWS EKS.

I'm working through the below Alfresco guide:

https://docs.alfresco.com/content-services/latest/install/containers/helm/#helm-deployment-with-aws-eks

Already, I have created an EKS cluster and completed the tasks as set out in the documentation.

Now however, I am trying to deploy the external-dns service.

I run this command:

kubectl apply -f external-dns.yaml -n kube-system

But receive the following error message:

"resource mapping not found for name: "external-dns" namespace: "" from "external-dns.yaml": no matches for kind "ClusterRole" in version "rbac.authorization.k8s.io/v1beta1"

ensure CRDs are installed first

resource mapping not found for name: "external-dns-viewer" namespace: "" from "external-dns.yaml": no matches for kind "ClusterRoleBinding" in version "rbac.authorization.k8s.io/v1beta1"

ensure CRDs are installed first"

After some investigation, I believe this to be related to the rbac.authorization.k8s.io/v1beta1 API not being supported by Kubernetes versions newer than v1.22 (see below).

https://kubernetes.io/docs/reference/using-api/deprecation-guide/

Installed on the EC2 instance from which I am running these commands is:

eksctl 0.126.0

Helm v3.11.0

kubectl v1.24.7-eks...

So my guess is that the provided external-dns.yaml is referencing an out of date API.

Must I downgrade Kubernetes or is there a non-deprecated rbac.authorization.k8s.io API I can reference please?

And should I be following the wrong instructions or if there is anything on which I can elaborate, I'm happy to share and discuss.

Thanks
