cewood/rclone repository overview

⁠Rclone Docker

An opinionated set of simple Docker containers with Rclone⁠ and Supercronic⁠.

⁠Usage

Being slightly opinionated there isn't any ENTRYPOINT specified, instead only a default CMD to run Supercronic with the bundled /etc/crontab file that simply echoes a short message once a minute. This means you can easily change what the container does without having to override an ENTRYPOINT, and if you want to use the Supercronic functionality you only need to mount in your own crontab file at /etc/crontab and run the container without any additional args.

⁠Docker Run

$ docker run --rm -it \
    -v $PWD/conf:/conf \
    -v $PWD/data:/data \

⁠Frequently Asked Questions

⁠Why Supercronic and not just regular cron

If we were running a normal system in an interactive manner, then normal Cron or friends (Anacron, Fcron, etc) would be fine choices. However in a containerised environment, these traditional cron implementations have some downsides, that make Supercronic a better fit. Namely the printing of jobs output to stdout, hence when running Supercronic as the ENTRYPOINT/CMD I can see the output of the jobs being run without having to jump through any hoops. There are undoubtedly other features that Supercronic brings with it that make it a better fit for use in containers, but this was the main motivator for me.
