Make an AWS Lambda function yourself

How can you generate a Golang lambda function similar to this one? Just type in sam init -r go1.x -n awesome-unicorns and there you go.

It requires you to have AWS SAM cli installed. You can installed via the following:

python3 -m pip install aws-sam-cli

Check that the script is installed properly by typing which sam.
