Quickstart

Simple backup using Docker CLI

To run a one time backup, bind your local volume to /backup in the container and run the backup command:

 docker run --rm --network your_network_name \
 -v $PWD/backup:/backup/ \
 -e "DB_HOST=dbhost" \
 -e "DB_USERNAME=username" \
 -e "DB_PASSWORD=password" \
 jkaninda/mysql-bkup backup -d database_name

Alternatively, pass a --env-file in order to use a full config as described below.

 docker run --rm --network your_network_name \
 --env-file your-env-file \
 -v $PWD/backup:/backup/ \
 jkaninda/mysql-bkup backup -d database_name

Available image registries

This Docker image is published to both Docker Hub and the GitHub container registry. Depending on your preferences and needs, you can reference both jkaninda/mysql-bkup as well as ghcr.io/jkaninda/mysql-bkup:

docker pull jkaninda/mysql-bkup
docker pull ghcr.io/jkaninda/mysql-bkup

Documentation references Docker Hub, but all examples will work using ghcr.io just as well.

Supported Engines

This image is developed and tested against the Docker CE engine and Kubernetes exclusively. While it may work against different implementations, there are no guarantees about support for non-Docker engines.

References

We decided to publish this image as a simpler and more lightweight alternative because of the following requirements:

• The original image is based on ubuntu and requires additional tools, making it heavy.
• This image is written in Go.
• arm64 and arm/v7 architectures are supported.
• Docker in Swarm mode is supported.
• Kubernetes is supported.
