Can you elaborate? How would that tools chart work and what does it do?

Mainly, I want to deploy other things that oap needs with one-click (easy).

Later, we can make our showcases into charts. For example, otel may need opentelemetry-collector charts and ksm charts. But if oap dependent on these charts, it feels inappropriate.

I'm still not very clear what should be put in the oap or operator chart, what should be put in the tools chart.

Let the tools chart do things that are not directly related to the oap or operator. I don't know if it's good.

Isn't that what the subchart does?

I'm currently migrating showcase to Chart, and this patch is one of the things needed.

Yes, so we should put these dependencies in showcase.

In my opinion the Helm Chart dependencies should be something that MUST have in order to make the main Chart work, though it can be pre-installed and we would use condition for that dependency. But optional features (like OTEL) should not add dependencies into Chart.
