The script for changing to overlay2 is now fully developed and will update your existing docker installation to use the overlay2 storage driver instead.

Regarding the AUFS driver

In the very early versions of the script we used AUFS as a storage driver, that is not yet supported as we didn’t test the migration properly. But don’t worry, you can run the update script as usual as we won’t continue the migration if you are running on AUFS.

Commands for starting your image

One thing to keep in mind though; when the migration is done you may have to start the image again manually. To do this you need to run one of these commands for OnlyOffice or Collabora:

Collabora:
$~: docker run -t -d -p 127.0.0.1:9980:9980 -e "domain=$NCDOMAIN" --restart always --name code --cap-add MKNOD collabora/code
OnlyOffice:
$~: docker run -i -t -d -p 127.0.0.3:9090:80 --restart always --name onlyoffice onlyoffice/documentserver 
Update as usual, no worries!

So all and all, just update as usual as the update script won’t destoy anything, rather fixing it. It won’t interfere with Nextcloud itself either as Docker is run separately from Nextcloud.

Just as a reminder; to run the update script just type this command in your CLI:

$~: sudo bash /var/scripts/update.sh

That’s all for now. And yeah, Nextcloud 15 is expected tomorrow. What a great feeling!
