Sontius is a AWS Lambda project to send alert messages to various chat services such as Slack. This is achieved by using Go to process the SNS message and send a formatted message on another service. The main application is written in Go as I wanted to learn some more Go and not JavaScript.

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 release of the prebuilt binary run the following:

make -e SLACK_URL=http:\/\/www.my-slack-url.com

Note: make sure to escape the forward slashes in the URL

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 (e.g. ./sonitus). Simply run node debug/start.js and it will send a message.
