Troubleshooting Ingress Service Unavailable 503
So if you are asking for ingress debugging steps, mine usually go along the lines of:
- Check if Service is available internally, this could be done by running a busybox container internally and just running curl commands against the endpoint
- Make sure that ingress selectors match the service that you have specified
- Make sure that Pods is up and running (log the pod etc).
- Make sure that ingress controller is not throwing errors (log the ingress controller)
It is a bit of a vague question as you could possibly have a host of issues wrong. I would say give us more info and we could better help understand your problem (i.e show use the yaml you use to configure the ingress)
