Hi @OskarMakowski,
thanks for posting in our community. It seems that the sonarqube user (uid 1000) does not have enough permissions to write in /opt/sonarqube/data, because of a misconfigured security context. Could you please try adding the following to the spec section of your deployment manifest?
<...>
spec:
securityContext:
fsGroup: 1000
<...>
Regards,
Carmine
