I am trying to install Jhipster Registry on Kubernetes as stateful set with the given (git as jhipster-registry.yml).

I see the services & statefulset coming up. I dont see the worker PODs :-(

Could you share, how to get the worker PODs up .

Update:

I am totally new to this jhipster & kubernetes. Thx for your response. Pasted the jhipster-register.yml below.
Cmds i have tried is to kubectl create -f jhipster-register.yml.

Error @ kubectl describe statefulset
