Install Istio addons (Prometheus, Grafana, Kiali, Jaeger) with Helm viaTerraform

Hello everybody,

I have installed Istio using the recommended Helm Charts via Terraform. However, I don not understand how to install the above mentioned addons. In online samples Istio was installed using the cli tool and the addons manifests were downloaded and applied locally.

Since I am using Terraform for IaC, I was wondering if i have to go to the website of the individual addons and install them via helm release or the addons is already present in the istio chart repository?

If i have to install each addon from it’s own repository, how do i then connect them to the already installed Istio?

If there are any other alternatives via Helm and Terraform, I would be grateful for your suggestions.
