Handle file uploads using third party tools

If you want to use an unsupported storage backend, or want to use a third party (e.g. rsync, rclone) tool for file uploads, you can build a Docker image containing the required binaries off this one, and call through to these in lifecycle hooks.

For example, if you wanted to use rsync, define your Docker image like this:

FROM offen/docker-volume-backup:v2

RUN apk add rsync

Using this image, you can now omit configuring any of the supported storage backends, and instead define your own mechanism in a docker-volume-backup.copy-post label:

version: '3'

services:
  backup:
    image: your-custom-image
    restart: always
    environment:
      BACKUP_FILENAME: "daily-backup-%Y-%m-%dT%H-%M-%S.tar.gz"
      BACKUP_CRON_EXPRESSION: "0 2 * * *"
    labels:
      - docker-volume-backup.copy-post=/bin/sh -c 'rsync $$COMMAND_RUNTIME_ARCHIVE_FILEPATH /destination'
    volumes:
      - app_data:/backup/app_data:ro
      - /var/run/docker.sock:/var/run/docker.sock

  # other services defined here ...
volumes:
  app_data:

{: .note } Commands will be invoked with the filepath of the tar archive passed as COMMAND_RUNTIME_BACKUP_FILEPATH.
