I have recently started to learn about Kubernetes and i'm trying understand why my ingress controller is giving a 502 error.

i'm working with google cloud platform. i can see my service of type: LoadBalancer is working if i connect using its static IP address, but it seems i may not have configured my ingress controller correctly because it gives a 502 error.

but it doesn't display any error when i deploy and i cant find any logs for the Ingress so i cant see why a 502 is being displayed.

  • Are you using Google Container Engine (GKE) or Google Compute Engine (GCE)? – ConnorJC Aug 19 '17 at 3:38
  • I'm using GKE, but if logs are available for GCE, I'd still like to know in case it is ever useful. – X0r0N Aug 19 '17 at 7:17

On GKE, Ingress logs are in the web console under Stackdriver Logging, under "Cloud HTTP Load Balancer":

  • I don't see "Cloud HTTP Load Balancer" in the dropdown list anymore. I'm having a weird random 502 error and need to check load balancer log, please help. – TrungDQ Aug 17 '19 at 10:54
  • Any idea to do it with the CLI ? – tisc0 Mar 5 '20 at 15:42

You should be able to view them the same as any other pod (kubectl logs -n namespace-name pod-name). The name and namespace will change depending on which ingress controller you're using.

Be aware that ingress controllers are often setup in a different namespace, so you may need to look for the pod in those. For example, the default configuration of the nginx ingress uses the namespace 'nginx-ingress'.

  • This is returns an error because it thinks it's looking for a pod rather than an ingress – Sinaesthetic Mar 13 '18 at 3:31
  • The ingress controller is a pod in almost all cases. – ConnorJC Mar 13 '18 at 3:40

    The GKE Ingress controller runs on a managed master node by GCP, not as a regular pod, so you are not able to view its logs or runa ny kubectl operations on it. – Tony Jun 27 '18 at 19:23
