Hello ! I am trying to deploying the Helm chart (Elastic only) but disabling the persistence of elasticsearch (

elasticsearch.persistence.enabled: false

) , kafka(

cp-helm-charts.cp-kafka.persistence.enabled: false

), zookeeper(

cp-helm-charts.cp-zookeeper.persistence.enabled: false

) and mysql (

mysql.primary.persistence.enabled: false

and

mysql.secondary.persistence.enabled: false

) to simplify my deployment (we don’t support persistence on our k8s server yet ), but it still deploys statefulset:

NAME                                          READY   AGE
statefulset.apps/elasticsearch-master         0/2     12m
statefulset.apps/prerequisites-cp-kafka       0/3     12m
statefulset.apps/prerequisites-cp-zookeeper   0/1     12m
statefulset.apps/prerequisites-mysql          0/1     12m

Any idea how to totally disable persistence and statefulness ?

No ideas here. prerequisites simply uses the open source charts for the underlying systems. You should take a look at their docs to see if you can disable statefulness, but to my knowledge I don’t think you can get away from stateful sets. But I believe there is a setting that disables persistent volumes if that is what you are looking for.
