Helm is amazing. If you are migrating legacy applications that rely on filesystem config, you can publish that config in a helm chart that applications require as sub charts. Gives you the ability to do centralized, versioned config management for legacy workloads going to the cloud
Declarative paradigms get a bad rap but I really just believe its people who missing imperative/functional programmimg. Theres a reason the infra space has been using declarative syntax for years now
The declarative functionality comes from K8s not helm. (Of course K8s has imperative tooling too but that’s not the point here).
The main reason folks dislike helm are 2 fold:
1) using string templating on a space formatted language is just messy and ugly for no good reason. If you don’t do anything terribly complicated it’s not too bad but quickly can be pretty fragile and unreadable.
2) golang(which I like generally) but the templating is messy and adds to the hard to read later problem
Personally find helm’s opportunity for code reuse to be restrictive and folks just end up cut and pasting a lot of declarations all over which is ... so terrible. But the first bullet above is pretty a fundamental design flaw.
