You can use volumes within docker-compose to store your configurations for your services, including other files and databases, on the host and pass them to the container to be used - 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
Run the below commands to update all services defined within your
docker-compose down docker container prune docker image prune -a #Verify you have no images left with your service, if you do, remove them. docker images -a docker-compose ps -a #Once you verify the above, you are ready to spin up your services and pull the latest images. docker-compose up -d
The 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.
For this example, we run the commands to update BookStack -
