Exercise 11.2: Ingress Controller - Error when creating ingress.yaml

Hi all,

Exercise 11.2: Ingress Controller - Step 7 - create ingress rules - fails!

Client Version: version.Info{Major:"1", Minor:"27", GitVersion:"v1.27.0", GitCommit:"1b4df30b3cdfeaba6024e81e559a6cd09a089d65", GitTreeState:"clean", BuildDate:"2023-04-11T17:10:18Z", GoVersion:"go1.20.3", Compiler:"gc", Platform:"linux/amd64"}

I went through the exercise as described and deployed the "myingress-ingress-nginx-controller". But when you try to create the rules as described in step 7, I'll receive an error message:

Error from server (InternalError): error when creating "ingress.yaml": Internal error occurred: failed calling webhook "validate.nginx.ingress.kubernetes.io": failed to call webhook: Post "https://ingress-nginx-controller-admission.ingress-nginx.svc:443/networking/v1/ingresses?timeout=10s": service "ingress-nginx-controller-admission" not found

The nginx log(s) show:

    Hi @mag1,

    Can you paste the ingress definition in a comment, as Code block?
