Hey @ramonskie,

thank you very much for the PR!

have not tested an upgrade scenario.

Is that something we should worry about? I've never seen the effects of changing
from a controller to another 🤔 (having never gone through an upgrade
like this).

---

Also, We're still finalizing some of the details of migrating ourselves out of
helm/charts into this repo (e.g., we want to have a pipeline that runs our e2e
tests, etc), so it might take a little while until we properly get this PR in
😬

thank you!

Is this going to be merged & released soon?
We have updated to 1.16 and cannot use the Concourse chart at the moment.

I too am struggling. More and more people are going to stumble upon this because of this error:

Error: validation failed: [unable to recognize "": no matches for kind "Deployment" in version "extensions/v1beta1", unable to recognize "": no matches for kind "StatefulSet" in version "apps/v1beta2", unable to recognize "": no matches for kind "StatefulSet" in version "apps/v1beta1"]

It means that you cannot install the concourse helm chart on Kubernetes 1.16

@ramonskie I also, ran into the same issue but I made changes locally adapting to 1.16 and running. Maybe you can run also run the same way until this is merged.

Approving this now. Sorry this took so long. We'll get this published on our chart repo sometime this week.
