Simple Helm Chart application with state managed by Terraform.
That is, use helm template and kubectl apply (so no helm rollback) with Terraform managing lifecycle instead of Helm. As a result, it should work with Helm v2 (but won't use Tiller since we're applying with kubectl) or v3 (which has no Tiller anyway).
Caveats:
- Lose helm functionality, as mentioned above - this is really just for using charts to manage configuration
- Assumes single user (local storage of rendered values) - this is avoidable, I just haven't yet
