## Description:

Hi everybody,  
I have installed the Percona XtraDB Cluster with helm on our kubernetes cluster: pxc-operator, haproxy, pxc-db. Per default it uses the pxc strict mode ENFORCING.

One of my applications which uses the Percona XtraDB cluster apparently has problems with the ENFORCING mode =\> Percona-XtraDB-Cluster doesn’t recommend using SERIALIZABLE isolation with pxc\_strict\_mode = ENFORCING. After switching to PERMISSIVE the application works.

Is there a way to change the Percona XtraDB cluster to pxc\_strict\_mode PERMISSIVE via helm upgrade with separate values.yaml file? Or is there another way for fixing that?

## Version:

helm app version: 1.14.0

Thank you very much!
