Nice, have you tested this change out by spinning a 1.25 ? Want to make sure images are published and accessible etc.

[ivelichkovich]

Yup they are tested

One minor comment, rest LGTM!

[prateekgogia]

what happens if SA already exists in the cluster and someone runs make apply?

[ivelichkovich]

It will work if it already exists and was created by the helm chart. If it was manually created though then helm will have a conflict with it.

LGTM!
