A block to simplify scheduling actions on your device

Setup and configuration

Use this as standalone with the button below:

Or add the following service to your docker-compose.yml:

version: "2.1"
volumes:
  scripts:
services:
  cron:
    restart: always
    image: ghcr.io/rcooke-warwick/cron:latest
    volumes:
      - "scripts:/data"
    ports:
      - "80:3000"

you can select the port used with an environment variable CHRON_PORT

Documentation

This block presents a simple API to allow you to create and remove cron jobs. For example, you can create a job to occur every 2 mins:

curl -X POST -H "Content-Type: application/json" \
    -d '{"minute": "*/2", "command": "echo hello-world"}' \
   DEVICE_URL/createJob

The syntax for specifying time intervals can be found here: https://ostechnix.com/a-beginners-guide-to-cron-jobs/

You can add scripts into the scripts volume, and schedule them to be run as described above if you want to schedule more complex tasks
