Kubernetes Ingress Controller GPC GKE can't reach the site

Question

Kube.netes Ingress Controller can't reach the site

Hi, this is the first time I am trying to deploy an application with kube.netes. The problem I am facing is I want to be able link subdomains with my svc, but when I try to navigate to the links I get

This site can't be reached

I will explain the steps I made for these, probably I something is wrong or missing

1. I installed ingress-controller on google cloud platform

2. In GCP -> Networking Services -> Cloud DNS

   a. I pointed testcompany.com with google dns

   b. I created an A record pointing the public IP from the previous step "ingress-nginx-controller"

3. my svc manifest

   apiVersion: v1 kind: Service metadata: namespace: staging name: testcompany-svc labels: app: testcompany-svc spec: type: NodePort ports: - name: test-http port: 80 protocol: TCP targetPort: 3001 selector: app: testcompany

4. my ingress manifest

   apiVersion:.networking.k8s.io/v1beta1 - host: api.testcompany.com http: paths: - backend: serviceName: testcompany-svc servicePort: test-http

Everything is green and it seems to be working, but when I try to reach the url I get the This site can't be reached

You should check this, in order:

1. your Service, Pod, Ingress are in the same namespace: kubectl get all -n staging
2. your Pod is listening on port 3001: run it locally if you can, or use kubectl port-forward pods/[pod-name] -n staging 3001:3001 and try it locally with http://localhost:3001/...
3. your Service is reaching your Pod correctly: use kubectl port-forward service/testcompany-svc -n staging 3001:3001 and try it locally with http://localhost:3001/...
4. check any other Ingress spec rules before the one you posted
5. check for firewall rules in your VPC.network, they should allow traffic from Google LBs
