@TylerHelmuth , @dmitryax , are you able to move this to the open-telemetry/opentelemetry-helm-charts rep?

[TylerHelmuth]

I can't bc I am not an approver in Collector Core 😞, but @dmitryax can. I normally take care of collector updates on the helm-side once the distributions are released. If the assign will carry over when moved, you can assign to me now.
