Have you tried plain manifests? Unless you need to support a lot of permutations (because of many environments, or you're distributing it and need to support many deployment options), Charts are generally a suboptimal way to get things running in k8s.

The major "wins" for using charts are usually around being able to use the same set of manifests with different values interpolated in. Which in turn, is really only valuable if you're supporting a large number of permutations that need to be kept in sync.
