[pulsar-operator] Disable/Debug startup probe failure

Hi,

I try to use the pulsar-operator:0.17.9 to deploy a relatively small pulsar cluster in GKE. My configuration includes only the manifests listed below (which are practically unchanged from the examples).

Everything set ups nicely and all of the resources are created validly, besides the bookkeepers - They fail due to startup probe checks with a "connection refused". The describe and logs of one of those pods is below as well.

The controller managers don't have any relevant log information.

I was wondering

Is there anyway I can easily disable the liveness checks so I can enter the containers for debug? Any other way to debug?
Do you have any idea for what the reason?

Any help will be appreciated.
Thanks!
