CRON Jobs

Create CRON Job

In order to create CRON jobs, just add a crons folder to less. Each CRON job is just another folder inside of less/crons.

Here's an example of a generate_daily_report CRON job.

mkdir -p less/crons/generate_daily_report

Node.js

touch less/crons/generate_daily_report/index.js

less/crons/generate_daily_report/index.js

exports.process = async () => {
  console.log('Generating report...');
};

Python

touch less/crons/generate_daily_report/__init__.py

less/crons/generate_daily_report/__init__.py

def process():
  # Your code here

Set CRON Schedule

In order to set the CRON schedule you will need to configure them as Environment Variables. The name of the variable should be CRON_ + the uppercase CRON folder name.

In the example of the generate_daily_report CRON the envoronment variable would be CRON_GENERATE_DAILY_REPORT:

export CRON_GENERATE_DAILY_REPORT="0 0 * * ? *"

Remember to add the env var to your less.config.

touch less.config

less.config

env_vars:
   - CRON_GENERATE_DAILY_REPORT
