Setup

Create a Twitter bot, and copy API keys in to AWS Secrets Manager. Inside of a secret named RandomGovTwitter, ensure you have:

• RandomGovConsumerKey
• RandomGovConsumerSecret
• RandomGovAccessToken
• RandomGovAccessTokenSecret

Deployment is managed by the Serverless Framework.

To deploy, make sure you are authenticated against AWS and then run:

serverless deploy

To deploy production, append --stage prod.

Once deployed, set up a CloudWatch Rule to periodically trigger the lambda.

How did I do any of this?

Let's be honest, you'll have forgotten all of this in the morning.

The bot is made up of a Python lambda deployed to AWS. It reads our Twitter secrets out of AWS Secrets Manager. It's periodically triggered by a Cloudwatch Rule.
