Run the build command then upload
sonitus.zip into your Lambda function. From there, subscribe your Alarms to a topic and add a Lambda subscription to that topic.
To build with the latest realase of the prebuilt binary run the following:
make -e SLACK_URL=http://www.my-slack-url.com
If you'd like to build the binary yourself, I'd recommend gox.
To replicate Lambda, there is a debug folder with a example Alarm message from SNS. Build a local binary and put the path to that binary into index.js instead of
/var/task/lambda. Simply run
node start.js and it will send a message.
