Lab 11.2. Ingress Controller error when creating ingress

eboyko

Hi

I receive an error when creating ingress:

kubectl create -f ingress.yaml

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://myingress-ingress-nginx-controller-admission.default.svc:443/networking/v1/ingresses?timeout=10s": notresolvable

How to resolve this?

Hi @eboyko,

On the earlier steps, when installing the nginx ingress controller, what are the outputs of the commands in step 6 (the get services and get pod).

kubectl --namespace default get services -o wide myingress-ingress-nginx-controller

Hi @eboyko,

Such a timeout indicates a firewall rule that blocks traffic to a required port number.

Hi, @chrispokorni,

I managed to solve this issue by adding .svc to no_proxy in /etc/kubernetes/manifests/kube-apiserver.yaml.

Thank you!
