Is that have a way to install Kiali on GKE ?
I use GKE and install Istio with GKE option, so I cannot use helm to install Istio with Kiali.
Many articles use helm to install Istio with Kiali, I couldn't find a way to just install Kiali without Istio.
Kiali provides instructions to install the Kubernetes operator on top of Istio if that's already installed.
Before you can use the Kiali scripts you will need to install prometheus on managed GKE/istio cluster; as explained here: https://cloud.google.com/istio/docs/istio-on-gke/installing#adding_prometheus. This is required for Kiali to get data about your cluster.
