Configuration

The following environment variables can be used to dictate which Slack webhook URL and channel are used:

• COFFEE_BUTTON_SLACK_WEBHOOK_URL: Slack webhook URL
• COFFEE_BUTTON_SLACK_CHANNEL: Slack channel to send messages to
• COFFEE_BUTTON_FUNCTION_ALIAS: When deploying, the alias associated with the Lambda function

Testing

Function testing occurs within a Docker container and is driven by make:

$ make test

Deployment

Function deployment will occurs automatically via Travis CI. If you choose to execute deployments manually, execute the following steps:

$ export COFFEE_BUTTON_SLACK_WEBHOOK_URL="https://hooks.slack.com/..."
$ export COFFEE_BUTTON_SLACK_CHANNEL="#general"
$ export COFFEE_BUTTON_FUNCTION_ALIAS="staging"
$ export AWS_SECRET_ACCESS_KEY="..."
$ export AWS_ACCESS_KEY_ID="..."
$ make deploy

This deployment process makes use of make and Apex to publish the function to Amazon Lambda.
