This repo is an example of how to run a Discord bot on AWS Lambda. It uses Discord Interactions Endpoint.
The app is built with Flask to create a HTTP server. The server is hosted on AWS Lambda Docker Container using AWS CDK.
Once you've replaced updated all the tokens and keys, you can deploy the bot to AWS Lambda with the CDK. You'll then get an API endpoint like https://xxxxx.execute-api.us-east-1.amazonaws.com/prod/.
You can then update the Discord application's interactions endpoint to point to that URL on your Discord Developer Portal, and interact with the bot in your Discord server (after you've added it to the server).
Before you can use the bot, you'll need to register the commands with Discord.
Modify/update the discord_commands.yaml file to add your own commands. Also install the dependencies in requirements.txt if you haven't already.
pip install -r commands/requirements.txtThen update the API key and application ID in register_commands.py to match your own. Then run the register_commands.py script in the commands directory.
cd commands
python register_commands.pySend a request to the Flask app this way. Put a sample request (which you can get by logging the JSON in Lambda). PUt it in test_request.json.
Start up the bot as a Flask app.
python src/app/main.pyThen send the request to the Flask app.
curl -X POST -H "Content-Type: application/json" -d @test_request.json http://127.0.0.1:5000/But this won't work with the @verify_key_decorator, because the request won't have a token that works with the public key.
So you'll need to comment out the decorator to test locally or update the example request with a valid token from your Lambda logs.
Bootstrap the CDK if you haven't already.
cdk bootstrapThen you can run this to deploy it (make sure your AWS CLI is set up first).
cdk deploy
