A simple demo application for how to setup a periodic task scheduler in golang

Simple Periodic task scheduler demo with golang

A lightweight attempt to mimic celery beat

Requirements

• github.com/RichardKnop/machinery/v1
• github.com/robfig/cron/v3
• docker

How to run

docker-compose up -d --build you may want to delete the build>args mapping in service worker1 for the first build

The docker-compose.yml file contains 4 services

• rabbit => rabbitmq service
• worker1 => Consumes tasks from the job queue
• worker2 => Consumes tasks from the job queue
• beat => Triggers periodic tasks, pushing them to the job queue

You can open 3 separate tabs and log the output of the different services

• docker-compose logs -f worker1
• docker-compose logs -f worker2
• docker-compose logs -f beat

The code presented here is by no means good code, just a simple demo of how you'd setup a job scheduler with support for periodic tasks
