AIO docker fonts

I installed nextcloud using docker all in one. The mastercontainer creates all the others, but i need to be able to make changes to the nextcloud-aio-collabora container. Specifically to allow new fonts that have been uploaded in the admin settings → office. How do I persist /etc/coolwsd/coolwsd.xml if im not able to specify a volume mount?

You can access to the volumes by going to /var/lib/docker/volumes there you have all the data from the different containers :wink:
