Error "no Route matched with those values" with the Kong ingress controller
Your rjup2 Service doesn't have a valid selector. Note that the Pods you are trying to expose are labelled with run: rjup2 label and your Service has app: rjup2 selector.
Btw. you get very clear error message that indicates where the problem could be:
service kong/rjup2 does not have any active endpointsIf your rjup2 service in kong namespace doesn't have any active endpoints, it means it doesn't expose your Pods properly which may indicate a possible mismatch in your configuration.
You can check it by running:
kubectl get ep -n kongNormally you should see the matching Endpoints object. In your case you won't see it as your Service cannot expose any pods untill it has a valid selector.
If you fix your Service definition, everything should work just fine:
apiVersion: v1kind: Servicemetadata: name: rjup2 namespace: kongspec: selector: run: rjup2 type: ClusterIP ports: - name: http port: 80 targetPort: 8888 protocol: TCP
