🚀 boca-chica-bot

I am a Twitter Bot that tweets status updates to beach and road closures related to SpaceX Starship testing in Boca Chica, TX.

How I Work

I periodically pull the published road and beach closures from the Cameron County SpaceX page to see if there are any changes or additions, then tweet them out as @BocaChicaBot.

I'm written in Go and run serverless in AWS using AWS Lambda, DynamoDB, and EventBridge.

Deployment

Terraform Cloud is utilized for deploying my infrastructure. I have two workspaces (access required to see these):

• boca-chica-bot-test
• boca-chica-bot-prod

Terraform Cloud Workspace Setup

Required Environment Variables for these workspaces in Terraform Cloud:

• AWS_ACCESS_KEY_ID
• AWS_SECRET_ACCESS_KEY
• TF_CLI_ARGS_plan=-var-file=workspaces/test.tfvars (for test)
• TF_CLI_ARGS_plan=-var-file=workspaces/prod.tfvars (for prod)

Required Terraform Variables in Terraform Cloud:

• twitter_consumer_key
• twitter_consumer_secret
• twitter_access_secret
• twitter_access_token

These are used to populate the Parameter Store with the required Twitter API creds.

Local Development

Create a .env file with these env vars set:

AWS_ACCESS_KEY_ID=
AWS_SECRET_ACCESS_KEY=
AWS_REGION=us-east-1
DEBUG=true
DISABLE_PUBLISH=true
TWITTER_ENVIRONMENT=test

The .env file is leveraged in the lambci/lambda:go1.x Docker container used to run the lambda handler locally:

make run
