@pbusko Just out of curiosity - have you tried running deploy-on-kind on a non-amd64 architecture?

It does work with noticeable performance degradation for emulated components, like Korifi API/Controllers and kpack. We're also working on bringing native arm64 support for kpack.
Some colleagues even reported issue when running ./scripts/deploy-on-kind.sh on certain VMs, with fork/exec errors highlighting architecture mismatch, failing local setup completely
