Installation

The image is available on Docker Hub as fuzzyio/backup-mongodb.

  docker pull fuzzyio/backup-mongodb

Configuration

The container makes a daily date-stamped backup of the MongoDB database you specify to its /backup directory. You'll typically want to attach a volume to the container so that it backs up to a location under your control.

The image uses the following environment variables:

• HOST: The host to connect to for getting the database. Can be a plain hostname like server1 or a replication set definition like myrepl/server1,server2,server3.
• DATABASE The database to back up. This image will only back up one database; run multiple containers if you need multiple databases backed up.

An example Docker Compose file:

version: '2'
services:
  foobar:
    image: mongo:3.2
  backup:
    image: fuzzyio/backup-mongodb
    links:
    - foobar:foobar
    volumes:
     - ./backup:/backup
    environment:
      HOST: foobar
      DATABASE: bazquux
