--set kiali.enabled=true \

Is it possible to add alertmanager to istio setup?

Answer 1

Is it possible to add alertmanager to istio setup?

Yes, it is possible.

As i could read on github

Generally Istio is not trying to manage production grade Prometheus, grafana, etc deployments. We are doing some work to make it easy to integrate istio with your own Prometheus, kiali, etc. See https://github.com/istio/installer/tree/master/istio-telemetry/prometheus-operator as one way you can integrate with the Prometheus operator. You can define your own Prometheus setup then just add the configs to scrape istio components.

You will have to change prometheus values and templates like there , add alertmanager yamls, and then configure it to work on istio namespace.

I would recommend to use

helm fetch istio.io/istio --untar

Which Download a chart to your local directory to view.

Then add alertmanager, and install istio helm chart from your local directory instead of helm repository.
