docker-rclone-cron

This is a very lightweight Docker image that runs rclone as a cronjob (inspired from https://github.com/openbridge/ob_bulkstash).

It makes backuping tasks or other syncing tasks very easy. Rclone being entierly configurable with environment variables (https://rclone.org/docs/#environment-variables), it should be pretty flexible.

See on Docker hub : https://hub.docker.com/r/olivierdalang/rclone-cron

Usage

docker run \
    -v ./backups/:/backups/ \
    -e "CRON_SCHEDULE=0 0 * * *" \
    -e "COMMAND=rclone copy /backups/ MYREMOTE:/path/where/to/backup/" \
    -e "RCLONE_CONFIG_MYREMOTE_TYPE=s3" \
    -e "RCLONE_CONFIG_MYREMOTE_ACCESS_KEY_ID=XXX" \
    -e "RCLONE_CONFIG_MYREMOTE_SECRET_ACCESS_KEY=YYY" \
    olivierdalang/rclone-cron

COMMAND is executed once on container startup (to test the config), and if it succeeded, cron will start in foreground.

See rclone's documentation for the command syntax and the RCLONE_CONFIG_* configuration. See cron documentation for CRON_SCHEDULE.

You could also define two remotes to do a remote-to-remote sync/copy.

Example

Example docker-compose.yml to sync a docker volume to Dropbox.

version: '3.4'
services:

  ... your other services here

  backup:
    image: olivierdalang/rclone-cron:latest
    environment:
      - CRON_SCHEDULE=0 * * * *
      - COMMAND=rclone sync -v /your_data_volume MYDROPBOX:some_path_here
      - RCLONE_CONFIG_MYDROPBOX_TYPE=dropbox
      - RCLONE_CONFIG_MYDROPBOX_CLIENT_ID=xxx
      - RCLONE_CONFIG_MYDROPBOX_CLIENT_SECRET=yyy
      - RCLONE_CONFIG_MYDROPBOX_TOKEN={"access_token":"zzz","token_type":"bearer","expiry":"0001-01-01T00:00:00Z"}
    volumes:
      - ./your_data_volume:/your_data_volume

One-shot

You can use the same image to do a one-shot sync, in this example from Dropbox to S3

Create the environement variables nano temp-env :

RCLONE_CONFIG_MYDROPBOX_TYPE=dropbox
RCLONE_CONFIG_MYDROPBOX_CLIENT_ID=xxx
RCLONE_CONFIG_MYDROPBOX_CLIENT_SECRET=yyy
RCLONE_CONFIG_MYDROPBOX_TOKEN={"access_token":"zzz-LwUL7bnOZm3_Kl9MEGzXh7f7SL_F","token_type":"bearer","expiry":"0001-01-01T00:00:00Z"}
RCLONE_CONFIG_MYS3_TYPE=s3
RCLONE_CONFIG_MYS3_ENDPOINT=https://aaa
RCLONE_CONFIG_MYS3_ACCESS_KEY_ID=bbb
RCLONE_CONFIG_MYS3_REGION=ccc
RCLONE_CONFIG_MYS3_SECRET_ACCESS_KEY=ddd
RCLONE_CONFIG_MYS3_ACL=public-read

Run the container in detched mode :

docker run --entrypoint "/bin/sh" --env-file temp -d olivierdalang/rclone-cron -c 'rclone -v sync MYDROPBOX:path/in/your/dropbox MYS3:your_bucket'
