This is a Docker container image available at innovate/restic-mysql that will do a MySQL dump directly to Restic. We use this in a Kubernetes cron job to back up our MySQL servers.
We use a multiarch build for the images where the architecture is set in the tag
innovate/restic-mysql:amd64-latest # x86-64/and64 build
innovate/restic-mysql:arm64-latest # arm64/arm64v8 build
innovate/restic-mysql:amdhf-latest # armhf build
The configuration is given via envvars, the following ones need to be set
- MYSQL_USER: username for MySQL
- MYSQL_PASSWORD: password for the user
- MYSQL_HOST: hostname of the MySQL server
- RESTIC_PASSWORD: password to encrypt the backup with
- RESTIC_REPOSITORY: repository for Restic to back up to
