Prudhvi, sorry for the late response. I’m working on getting a Kong + Istio how-to blog post out by next week. In the meantime, check out https://bit.ly/kong-istio-demo as a starting point.

Kubectl apply this yaml file and it will install kong db-less and configure your gateway via ConfigMap.

Edit: Here is the blog post!

Kong Ingress controller is unable to route request to Istio virtual services

We’re running Istio service mesh on Kubernetes and Kong as API gateway and ingress controller for our K8S cluster. We’ve created virtual services and destination rules for our micro-services and communications between our micro-services are working as expected except Kong is sending traffic directly to Upstream server instead of applying the virtual service and destination rules. Scenario We have a micro-service deployed with 3 different versions and we have created virtual service to send tr…

Hi, I got some problem when installing kong above istio in postgresql mode(I have a requirement to use OAuth2), could you help me with that?

Istio sidecar problem

Hi, I check the installation today and I found it’s not the job problem. Actually, the migration command has done. [image] However, the initcontainer “wait-for-db” in kong cannot run kong start. I exec the container and get the debug info as : [image] Actually, the postgresql can be accessed [image] I don’t know what can I do to fix “unexpected message during auth”.
