minback-mariadb

Minio Backup container for MariaDB

Note

Inspired by gh/SierraSoftworks/minback-mysql.

This container provides a trivially simple means to run mariadb-dump and fire the results off to a Minio instance.

Features

• Dumps a single MariaDB database to an S3 bucket
• Lightweight and short lived
• Simple and readable implementation
• Compression and ARM64 and AMD64 Docker Images

docker run --rm --env-file backup.env ghcr.io/resmo/minback-mariadb:main
