What is the corrrect way to install remote Helm applications via Argo CD?

I need to install loki-stack to my k8s cluster, previously I need to change retention_deletes_enabled and retention_period in charts/loki/values.yaml.

What should I do to achieve this?

The problem is that there are several values.yaml files and I can't change loki values (charts/loki/values.yaml), I only can change the main loki-stack/values.yaml of this app when I create new application in Argo CD.

In general is it the correct way to clone the repo or doing helm pull then add this code to local git repository and create app from it?

If I understood your question correctly, you want to configure the "Loki" Helm chart when installing the "Loki-Stack" Helm chart.

The Loki-Stack Helm chart has several sub-charts (dependencies), each of which is available with its own name through the values.yaml: https://github.com/grafana/helm-charts/blob/main/charts/loki-stack/values.yaml

So for example if you want to configure where Loki stores the logs, you would do that as follows in the loki-stack Helm Helm chart:
`loki: #

Note that you need the extra "loki" entry to correctly pass the values to the sub-chart. Read me more here: https://helm.sh/docs/chart_template_guide/subcharts_and_globals/
