Volumes/theme Owncloud in kubernetes (K8S)


I have installed owncloud on kubernetes using image owncloud/server:latest.
I use persistent volume in order to keep data in volume root /mnt/data.
( https://github.com/owncloud-docker/server ) everything works fine and i can see apps,files,config.

Now i want custom my logon page like the logo, but howto do that ? themes => ‘’ doesn’t exist in config.php.

If i try to connect directly on my pod with kubectl exec , i don’t have directorty /var/www/* or /var/lib/owncloud

Best Regards,
