The docker image simply runs xtrabackup to create mysql backups. It only preserve one previous backup.
The example can be found in example directory. Make sure you always mount the image's /var/lib/mysql to the mysql service's /var/lib/mysql directory.
Also you need to mount the backup directory to /backups.
Example docker-compose.yml:
version: '3'
services:
db:
image: mariadb:5
restart: always
volumes:
- db-data:/var/lib/mysql
environment:
MYSQL_ROOT_PASSWORD: ${MYSQL_PASSWORD}
ports:
- '3306:3306'
xtrabackup:
image: webtoolsdev/simple-docker-xtrabackup:latest
environment:
MYSQL_HOST: ${MYSQL_HOST}
MYSQL_USER: ${MYSQL_USER}
MYSQL_PASSWORD: ${MYSQL_PASSWORD}
volumes:
- ./backups:/backups
- db-data:/var/lib/mysql
volumes:
db-data:
To back up your database, you only need to run
docker-compose run --rm xtrabackup mysql-backup
