ingress-nginx wasn't installed properly?-CodePudding

Now I'm using WSL 2 and Docker Desktop on Windows 10.

I created an YAML script to create an ingress for my microservices like below.

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-srv
  annotations:
    kubernetes.io/ingress.class: nginx
spec:
  rules:
    - host: posts.com
      http:
        paths:
          - path: /posts
            pathType: Prefix
            backend:
              service:
                name: posts-clusterip-srv
                port:
                  number: 4000

And I installed ingress-nginx by following this

And when I ran the command kubectl apply -f ingress-srv.yaml, it showed an error message.

Can anyone please let me know what the issue is?

I removed the namespace ingress-nginx using this command kubectl delete all --all -n ingress-nginx and ran the deploy script again.

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.4.0/deploy/static/provider/cloud/deploy.yaml

But the issue still happened.

CodePudding user response：

There is an issue deploying ingress-nginx controller. You need to first fix issues there before deploying the ingress. Because, only the nginx controller knows how to handle the ingress resources.

Since there is no much info about the controller deployment failure, you better add more details about the error. You can describe the controller pod and share its event and status to look into this further.

CodePudding user response：

It was because of the corrupted filesystem.

When I ran the ingress-nginx deployment command, there was a docker-desktop crash because of the lack of drive storage size.

So I removed all corrupted, unused or dangling docker images.

docker system prune

Also I deleted ingress-nginx and reinstalled.

kubectl delete -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.4.0/deploy/static/provider/cloud/deploy.yaml

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.4.0/deploy/static/provider/cloud/deploy.yaml

After that, it worked well.

kubectl get pods --namespace=ingress-nginx
