Local Testing

Pre-requisites

• Discord Bot Token (See: https://discord.com/developers/docs/quick-start/getting-started)
• Discord Channel IDs (Last part of the channel URL, e.g., https://discord.com/channels/123/5678 -> 5678)
  • ANNOUNCEMENTS_CHANNEL_ID - Where to send notifications about new, updated, and cancelled events.
  • EVENTS_CHANNEL_ID - Where to create discussion threads for events ending soon.

Run Locally

Create a .env file with the following vars:

DISCORD_TOKEN="asdf.ghjkl"
ANNOUNCEMENTS_CHANNEL_ID="1234"
EVENTS_CHANNEL_ID="2345"

Run the bot with the following command:

docker compose up

Update Cloud Deployment

Directly on Fly.io

• Run fly deploy after making the code changes.
• If two machines end up being deployed, scale down using fly scale count 1.

Note: Fly.io only uses the Dockerfile and ignores the compose.yml file.

Using GitHub Actions

• GitHub Actions are set up to automatically deploy the bot to Fly.io on every push to the main branch.
