This is a simple script to backup a MongoDB database using mongodump and upload it to a remote storage using rclone. It is intended to be used as a cron job.

Usage

bash ./entrypoint.sh

Usage with Docker

Run the following command to backup a MongoDB database and upload it to a remote storage using rclone.

docker run \
  -e MONGO_DB=mydb \ 
  -e MONGO_COLLECTION=mycollection \
  -e RCLONE_REMOTE=myremote \
  -e RCLONE_REMOTE_PATH=/path/to/remote \ 
  -e MONGO_URI=mongodb://myuser:xxxxxxxxxx@xxxxxx:27017/mydb \ 
  -v $HOME/.config/rclone:/config/rclone \ 
  --rm \ 
  -it \
  mongodump-rclone

Usage with Docker Compose

You can use the following docker-compose.yml file to backup a MongoDB database and upload it to a remote storage using rclone.

services:
  mongodump:
    image: mongodump-rclone
    environment:
      - MONGO_DB=mydb
      - MONGO_COLLECTION=mycollection
      - RCLONE_REMOTE=myremote
      - RCLONE_REMOTE_PATH=/path/to/remote
      - MONGO_URI=mongodb://myuser:xxxxxxxxxx@xxxxxx:27017/mydb
    volumes:
      - /home/user/.config/rclone:/config/rclone
  mongoexport:
    image: mongodump-rclone
    environment:
      - USE_MONGOEXPORT=true
      - MONGO_DB=mydb
      - MONGO_COLLECTION=mycollection
      - RCLONE_REMOTE=myremote
      - RCLONE_REMOTE_PATH=/path/to/remote
      - MONGO_URI=mongodb://myuser:xxxxxxxxxx@xxxxxx:27017/mydb
    volumes:
      - /home/user/.config/rclone:/config/rclone

Run the following command to start the services.

docker-compose up # for both services
docker-compose up mongodump # for mongodump
docker-compose up mongoexport # for mongoexport

Configuration

The backup can be performed using the mongodump command or the mongoexport command. The script will use mongodump by default. You can change this behavior by setting the USE_MONGOEXPORT environment variable to true.

The script uses environment variables to configure the backup and upload process.

mongodump

Variable	Description	Required	Default
RCLONE_CONFIG	The content of the rclone configuration without it's name.	No	None
RCLONE_REMOTE	The name of the rclone remote to upload the backup to.	No	default
RCLONE_REMOTE_PATH	The path on the remote storage where the backup will be uploaded.	No	/
MONGO_DB	The name of the MongoDB database to backup.	No	None
MONGO_COLLECTION	The name of the MongoDB collection to backup.	No	None
FILENAME	The base name of the backup file.	No	mongodb
FILENAME_TIMESTAMP	Whether to include a timestamp in the backup file name (true/false).	No	true
MONGO_URI	The MongoDB connection URI.	No	None
MONGODUMP_ARGS	Additional arguments to pass to the mongodump command.	No	None
RCLONE_ARGS	Additional arguments to pass to the rclone rcat command.	No	None

mongoexport

Variable	Description	Required	Default
RCLONE_CONFIG	The configuration for rclone.	Yes	None
RCLONE_REMOTE	The name of the remote to use with rclone.	No	"default"
RCLONE_ARGS	Additional arguments to pass to rclone.	No	None
RCLONE_REMOTE_PATH	The path in the remote to store the exported data.	No	"/"
MONGOEXPORT_ARGS	Additional arguments to pass to mongoexport.	No	None
FILENAME	The base name of the output file.	No	"mongodb"
MONGO_DB	The name of the MongoDB database to export.	Yes	None
MONGO_COLLECTION	The name of the MongoDB collection to export.	Yes	None

MONGOEXPORT_TYPE	The type of the export file (json or csv).	Yes	"json"

In case the MONGO_URI is not provided, the script will try to connect to the MongoDB server running on localhost using the default port 27017.

If you want to use a rclone config file, you can mount the directory containing the file to /config/rclone. i.e docker run -v /home/user/.config/rclone:/config/rclone.
