S3 backup for Docker

A docker container to backup an S3 bucket to another bucket or SFTP server.

Configuration

Create a configuration file as described in the ten7.s3_backup Ansible role.

Once created, you have three ways to provide it to the container:

• As a base64-encoded value of the S3_BACKUP_CONFIG environment variable
• As a mounted file at the location specified by the S3_BACKUP_CONFIG_FILE environment variable
• As a mounted file at /config/s3-backup/s3-backup.yml inside the container.

Use with base Docker

To run the Docker image as part of a script or in cron, use the following command:

docker run --rm -v /path/to/s3-backup.yml:/config/s3-backup/s3-backup.yml ten7/s3-backup

Note, that if your s3-backup.yml file depends on other files (such as SSH keys) you will need to add multiple -v switches to mount each one.

Docker compose

Create the following Docker Compose file.

version: '3'
services:
  backup:
    image: ten7/s3-backup
    volumes:
      - /path/to/s3-backup.yml:/config/s3-backup/s3-backup.yml

Again, if your s3-backup.yml depends on other files (such as SSH keys) you will need to add additional items under volumes to mount them.

Once the docker-compose.yml file is created, you can run backups using:

docker-compose run backup
