Random Daily 🌅

Name randomizer for standups and on-call rotation slack message publisher

This code is for creating a webhook that triggers:

• Name list randomizer and publishes it to a URL
• Name rotation based on the week number of the year

Randomizer Setup

Slack

1. On the Slack menu, select Tools > Workflow Builder
2. Create a new Workflow and come up with a name
3. Select Webhook from the list
4. Add a variable as text

• r_list for the random list endpoint.
• name for the on-call endpoint.

5. Add a new step after the Webhook Send a message
6. Pick the channel where you want to send the message
7. Add a message and insert the previously created variable and save
8. Publish it (top right button) and copy the URL because you'll need it later on

Creating a serverless function

You can either use a serverless function already created by one of your teams or create a new one using a service like Vercel.

Cron Job for continuous excecution

The idea is to use a cloud scheduler for running this task every morning or at the time of your daily. In the case of the on-call we like to run it every monday.

We're using Google Cloud Scheduler for this, but you could also use EasyCron

URL to call:

random list

https://<cloud function service>/api?members=mario,luigi,peach&url=<URL-from-Slack>

Live url: https://random-daily.vercel.app/api/?members=mario,luigi,peach&url=

on-call

https://<cloud function service>/api/on-call?members=Name01,Mane02,Mane03&url=<URL-from-Slack>

Live url: https://random-daily.vercel.app/api/on-call?members=mario,luigi,peach&url=

When to excecute:

Select manually and added the time and days of the week we wanted this to be triggered.

Test

Hit the test button after saving the cron job and check your slack channel.
