Figure out Injection of Envoy SideCars with current Pods #31

Open AnshulV98 opened 4 years ago

AnshulV98 commented 4 years ago

As Istio has been installed on Jetsream instance, it has been setup with the default namespace with auto envoy sidecar injection mode enabled such that, whenever a pod is re/deployed or re/started it would be injected with an Envoy sidecar

The current issue is if you run 

istioctl analyze

you get this result 

Warn [IST0103] (Pod rabbitmq-controller-fm5rz.default) The pod is missing the Istio proxy. This can often be resolved by restarting or redeploying the workload.

A possible solution for this could be to edit all the YAML files and enter a name: field inside the port: fields to name every port this could possibly resolve this issue

Even that might not solve the problem because the issue seems to be with the LodeBalancer type which we are currently using instead of NodePort type for the services.

Automatic sidecar injection is working perfectly, the only reason we were not able to access kiali dashboard was istio services are by default of type Loadbalancer, which needed to be changed to NodePort in the yaml file.
