Honestly my take on Helm charts is to keep them as simple as possible. All the complicated stuff you see in public charts people publish? Yeah stay far, far away from that. Our Helm charts at my job are 95% plain YAML files with an occasional variable insertion to handle cases where you need different hostnames (etc) based on the environment being deployed to. They are a pleasure to work with because they are so simple.

Even some of the examples in TFA (like the optional persistent storage one) are IMO way more complex than what you should use Helm for. At that point you're better off using a programming language to generate the YAML based on some kind of state object you create. It's way too error prone to do that stuff with YAML templating imo.
