Updating
Updating BookStack when running a docker container is easy. You can use mounted volumes to store the hosted data, including the databases, on the host and pass them to the container to be used by the services - this enables you to easily remove containers and purge images without worrying about backing up your data. As personal preference, I still run manual backups using the instructions shared on the Backup BookStack Page, but you shouldn't need to worry as the data is never touched when you are updating these images - the only concern would be if the image changes the way it uses the information, in which case you may need to change some paths for the volumes within your docker-compose.yml.
Run the below commands to update BookStack -
docker-compose down
docker image prune
#Verify you have no images left with your service, if you do, remove them.
docker-compose images
#Once you verify the above, you are ready to spin up your services and pull the latest images.
docker-compose up -dThe above commands are more general and less specific to BookStack, and the same approach could be used to update containers for any service you are using, just be sure to persist and / or backup your data.
