latest
Dockerfile to build an image which allows to create backup archives on daily basic. This image is based on Alpine Linux and s3cmd tool. You can use this image to create backup archives and store them on local folder or upload to S3.
Pull the image from the docker registry. This is the recommended method of installation as it is easier to update image. These builds are performed by the Docker Trusted Build service.
docker pull outcoldman/backup:latest
Alternately you can build the image locally.
git clone https://github.com/outcoldman/docker-backup.git
cd docker-backup
docker build --tag="$USER/backup" .
At first if you want to upload backups to AWS S3 you need to create new bucket on S3 and create an user in IAM with next policy (don't forget to update bucket locations)
