CloudFormation update tweet bot, posting under @cfnupdates

Requirements

• AWS CLI with Administrator permission
• Python 3 installed
• Pipenv installed
  • pip install pipenv
• Docker installed
• SAM Local installed

As you've chosen the experimental Makefile we can use Make to automate Packaging and Building steps as follows:

        ...::: Installs all required packages as defined in the Pipfile :::...
        make install

        ...::: Run Pytest under tests/ with pipenv :::...
        make test

        ...::: Creates local dev environment for Python hot-reloading w/ packages:::...
        make build SERVICE="cfnbot"

        ...::: Run SAM Local API Gateway :::...
        make run

Testing

Pytest is used to discover tests created under tests folder - Here's how you can run tests our initial unit tests:

make test

Local development

Given that you followed Packaging instructions then run the following to invoke your function locally:

Invoking function locally without API Gateway

echo '{}' | sam local invoke BotFunction

Deployment

You will need to create a file in the local repo named .twitter_keys with the contents:

export TWITTER_ACCESS_TOKEN_KEY='access-token-key'
export TWITTER_ACCESS_TOKEN_SECRET='access-token-secret'

The keys can be generated using the get_access_token.py script.

Once ready, deploy using the deployment script.

./deploy.sh
