The tool uses aws-sdk-go and is inspired by my coworker Erik Maciejewsk's ec2find, which is written in Python and boto library.

As a cloud engineer working with AWS, finding an instance IP private address and ssh into it could be a daily task. A tool like this would improve efficiency. My goal is to write something useful in golang as it can be compiled into a single binary, ideal for devops toolchain.
