Minikube with Istio Gateway Connection Refused

6/7/2017

I'm trying to get a local kubernetes cluster running with Minikube and Istio. I followed the instructions found in the istio docs here: https://istio.io/docs/tasks/installing-istio.html

Then I followed the steps to install the sample BookInfo sample here: https://istio.io/docs/samples/bookinfo.html

However when I try and curl the Gateway URL, I get a connection refused error. All my pods and services appear to be running. Here is the result of the kubectl get pods command:

Here is the result of the kubectl get services command:

servicegraph    10.0.0.230   <pending>     8088:32648/TCP                14m

Then I run these commands:

export GATEWAY_URL=$(kubectl get po -l istio=ingress -o 'jsonpath={.items[0].status.hostIP}'):$(kubectl get svc istio-ingress -o 'jsonpath={.spec.ports[0].nodePort}')
curl -o /dev/null -s -w "%{http_code}\n" http://${GATEWAY_URL}/productpage

The response I get is 000. Hitting the endpoint with my browser gives me a connection refused error. I had this working at some point, and I have no idea where it broke down the line. Any help would be greatly appreciated!

This is more a support/troubleshooting question

Can you link this question in https://github.com/istio/issues/issues and click "New Issue", link the great details you already did put here but also add the value of GATEWAY_URL and/or the full output of

curl -v http://${GATEWAY_URL}/productpage

there. thanks !

Also Minikube v0.19.0 has known issues, please upgrade to v0.19.1 and try again to see if this alone solves your problem?
