Discord Bot for Notifications

---

Environment Info

BOT_DEBUG=true
TZ="UTC" # Very important to configure host clock to UTC
DSCRD_BOT_TK="token"
CONFIG_FILE="/path/to/config.json"

---

The CONFIG_FILE

This document is to be stored alongside the bot, in a container environment this file will need to be created and placed in the location you point to with the environment variable.

This file should look like:

[
    {
        "cron": "0 0 * * *",
        "channelId": "01234567890",
        "message": "Hello World",
        "timezone": "America/New_York"
    }
]

In this file you have a outermost array which can contain as many of these, as I call them notification objects as you want. Each object has 3 properties:

Key Name	Description
cron	This is a typical Cron expression, any errors should be printed on first load
channelId	A channel which is on a server the provided Discord token has access to
message	Any text including supported Discord formatting
timezone	Any IANA Time Zone valid value to set the cron clock

Container Runtime

This section covers two scenarios of running the app, one in Docker and one in Kubernetes.

Docker

See docker-compose

Kubernetes

Create ConfigMap for the configuration yaml as such:

apiVersion: v1
kind: ConfigMap
metadata:
  name: bot-config
  namespace: bot-namespace
data:
  config.yaml: |
    [
      {
        "cron": "0 */2 * * *",
        "channelId": "790751594982801420",
        "message": "<@176355202687959051> Time to play pokemon",
        "timezone": "America/New_York"
      }
    ]

Within the container configuration section on a Deployment or StatefulSet:

... (Deployment type - within spec)
containers:
- env:
  - name: CONFIG_FILE
    value: "/tmp/config.yaml"
  image: ghcr.io/bananaztechnology/discord-notification-bot:latest
  imagePullPolicy: Always
  name: notif-bot
  volumeMounts:
  - name: config-volume
    mountPath: /tmp
volumes:
- name: config-volume
  configMap:
    name: bot-config
