Run as nonRoot user

The deployment fails with `Error: EACCES: permission denied, mkdir 'logs'` after adding 
```
podSecurityContext:
    fsGroup: 1000
    runAsUser: 1000
    runAsGroup: 1000
```
Which is needed since the container runs as non-root user and the image runs as root. There should be a way to run the image as non root user.
