didstopia/cron repository overview

⁠Cron - Scheduled Container Tasks

The ideal base image for cronjob based containers.

⁠Usage

Note that the intended use case for this image is to use it as a base image!

Basic usage example:

docker run \
    -e TZ="Europe/Helsinki" \
    -e SCRIPT_SCHEDULE="everyminute" \
    -e SCRIPT_WORKING_DIRECTORY="\/data" \
    -e SCRIPT_STARTUP_COMMAND=".\/script.sh" \
    -v $(pwd)/sample_script.sh:/data/script.sh \
    --name cron \
    -it \
    --rm \
    didstopia/cron:latest

See [Dockerfile] for further options.

⁠Scheduling

The built-in scheduler can be configured by simply setting SCRIPT_SCHEDULE to any of the following string values:

• everyminute
• 15min
• hourly
• daily
• weekly
• monthly

⁠Known Issues

• Cron should ideally log output to both a file and to /dev/stdout, and this should be user configurable
• Time zone should be taken into account in cron logs (eg. when setting TZ="Europe/Helsinki")
• Users should not have to escape slashes in environment variables (eg. when using SCRIPT_WORKING_DIRECTORY or SCRIPT_STARTUP_COMMAND)
