At this rate I'm going to have to dump Linode and go with someone else.

Modifications to the installation instructions.

Replace the ingress-nginx installation with this:

helm upgrade --install ingress-nginx ingress-nginx \
  --repo https://kubernetes.github.io/ingress-nginx \
  --namespace ingress-nginx --create-namespace

Replace the docker-registry installation with this:

Change docker-configs.yaml setting ingress.annotations/kubernetes.io/ingress.class to ingress.annotations/kubernetes.io/ingress.className:

ingress:
  annotations:
    kubernetes.io/ingress.class: nginx

ingress:
  annotations:
    kubernetes.io/ingress.className: nginx

Install with:

$ helm repo add twuni https://helm.twun.io
$ helm install docker-registry twuni/docker-registry -f docker-configs.yaml

I just checked and this is a typo in the How to Set Up a Docker Registry with LKE and Object Storage documentation.

Instead of

helm install ingress-nginx ingress-nginx/nginx-ingress

You would need to use this:

helm install ingress-nginx ingress-nginx/ingress-nginx

I was able to get the Nginx Ingress on LKE guide working without issue.

I'm having problems getting this working, even running with your command.

STATUS                     REASON          MESSAGE
Failure                    InternalError   an error on the server ("unable to decode an event from the watch stream: http2: client connection lost") has prevented the request from succeeding

See below.

Installation.

$ helm upgrade --install ingress-nginx ingress-nginx  --repo https://kubernetes.github.io/ingress-nginx  --namespace ingress-nginx --create-namespace
Release "ingress-nginx" does not exist. Installing it now.
NAME: ingress-nginx
LAST DEPLOYED: Sat Jul 30 21:54:58 2022
NAMESPACE: ingress-nginx
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
The ingress-nginx controller has been installed.
It may take a few minutes for the LoadBalancer IP to be available.
You can watch the status by running 'kubectl --namespace ingress-nginx get services -o wide -w ingress-nginx-controller'

An example Ingress that makes use of the controller:
  apiVersion: networking.k8s.io/v1
  kind: Ingress
  metadata:
    name: example
    namespace: foo
  spec:
    ingressClassName: nginx
    rules:
      - host: www.example.com
        http:
          paths:
            - pathType: Prefix
              backend:
                service:
                  name: exampleService
                  port:
                    number: 80
              path: /
    # This section is only required if TLS is to be enabled for the Ingress
    tls:
      - hosts:
        - www.example.com
        secretName: example-tls

If TLS is enabled for the Ingress, a Secret containing the certificate and key must also be provided:

  apiVersion: v1
  kind: Secret
  metadata:
    name: example-tls
    namespace: foo
  data:
    tls.crt: <base64 encoded cert>
    tls.key: <base64 encoded key>
  type: kubernetes.io/tls
