@rajat-soda Would it be possible to move the authchecker Docker file and code to another repository and make the changes there?
Since we are looking to make many changes going forward it would be best if we can start in an appropriate location like sodafoundation/auth or something like that.

[rajat-soda]

Yes, that is the plan. This is a WIP pr. Will be creating new repo for Soda Identity.
