Helmfile
Helm is totally adequate (I’m uncomfortable calling it good) for deploying an app, and potentially a small number of dependencies. It can quickly spiral out of control when there are many services that need deploying, with varying levels of dependency.
Helmfile is great for describing a large set of charts to deploy, and their values. It’s nice to be able to set values per environment, and to be able to deploy charts from a variety of sources - git repos, official repos, and the local filesystem.
write-values
Ensuring you get the correct YAML and Go template encantation can be annoying,
and testing it out by deploying is not ideal. In lieu of proper testing,
helmfile write-values is great as it runs all the templating and dumps files
on disk for inspection
