I was on a process to dockerize my infrastructure and I wanted to archive a service I couldn't simply migrate to a newer version nor really use anymore.
So I used Docker to archive it without depending on any dependency.
# First I go into the website's directory
cd /var/www/BookStack
# I generate a SQL script as a backup of the database named "bookstack_db"
mysqldump -u root bookstack_db > bookstack-backup-db.sql
# Then I used tar to create an archive of files (.env, uploads)
tar -czvf bookstack-backup-files.tar.gz .env public/uploads storage/uploads
# Then I take the version of BookStack
cat version
Then I download those files back to my laptop.
mkdir bookstack-backup
cd bookstack-backup
rsync -rv debian@snowcode.ovh:/var/www/BookStack/bookstack-backup-* .
Then, I created a docker-compose file with the following content to describe my infrastructure.
version: "2"
services:
bookstack:
image: ghcr.io/linuxserver/bookstack:version-v0.31.4 # Here goes my bookstack version
container_name: bookstack
environment:
- PUID=1000
- PGID=1000
- APP_URL=http://localhost:8080
- DB_HOST=bookstack_db
- DB_PORT=3306
- DB_USER=bookstack
- DB_PASS=secret
- DB_DATABASE=bookstackapp
volumes:
- ./bookstack_files:/config
ports:
- 8080:80
depends_on:
- bookstack_db
bookstack_db:
image: lscr.io/linuxserver/mariadb:10.6.10
container_name: bookstack_db
environment:
- PUID=1000
- PGID=1000
- MYSQL_ROOT_PASSWORD=secret
- TZ=Europe/Brussels
- MYSQL_DATABASE=bookstackapp
- MYSQL_USER=bookstack
- MYSQL_PASSWORD=secret
volumes:
- ./bookstack_db:/config
Finally I can start the server with that config...
sudo docker-compose up
...and place the files into the right volumes/directories.
sudo su # I need to be root for accessing the volumes
mv bookstack-backup-files.tar.gz bookstack_files
mv bookstack-backup-db.sql bookstack_db
cd bookstack_files
tar xvzf bookstack-backup-files.tar.gz
Finally I can enter the running container of my database to import the script
sudo docker exec -it bookstack_db bash -c "mysql -u bookstack -p bookstackapp < /config/bookstack-backup-db.sql"
# The default password is secret as defined in the docker-compose
The website can be accessed at http://localhost:8080
Archiving the Docker images
Now to not depend of the Docker registeries we can also archive the images of mariadb and bookstack
First we can list the images:
sudo docker images
Then take the IDs of the mariadb and bookstack images to export them into a TAR archive.
sudo docker image save aad0c49aebf3 -o bookstack.tar
sudo docker image save 39a4293c3071 -o mariadb.tar
Now it's done ! When we need it we can import the images back from the archives using those commands:
sudo docker image import bookstack.tar ghcr.io/linuxserver/bookstack:version-v0.31.4
sudo docker image import mariadb.tar lscr.io/linuxserver/mariadb:10.6.10
And now you no longer depends on those registeries either for using this backup.
