Question

I have successfully installed istio and deployed some sample app and application is up and running.

root@master:~# kubectl get pod
NAME                         READY   STATUS    RESTARTS   AGE

prometheus-7bfddb8dbf-nd4gn             2/2     Running   35         15d

Next i changed kiali dashboard cluster IP to Nodeport to access the dash brad from the browser

kubectl patch svc kiali -n istio-system --type='json' -p '[{"op":"replace","path":"/spec/type","value":"NodePort"},{"op":"replace","path":"/spec/ports/0/nodePort","value":30010}]'

Finally i can able to access the dashboard using node port with my host Ip http://machineip_port/ and could see my k8 namespaces without any apps please find the attached screen shot

could you please help me someone last one week i am running into this issue.

Answer 1

The problem is that

"Namespaces that do not exist at the time of install but are created later in the future will not be accessible by Kiali". Resource.

So, first, keep in mind you should not edit kiali's ConfigMap, but only Kiali's Custom Resource Definition(CRD), which is used by Kiali Operator.

Run kubectl edit kiali kiali in the namespace you have the CRD available.

Then add the following under spec:

spec:
  deployment:
    accessible_namespaces:
    - ["**"]

This will give Kiali access to all current namespaces and to any you'll create in the future.
