WhaleTail
WhaleTail is a Go program which is designed to reverse engineer a Docker Image into the Dockerfile that created it. It currently performs the following actions
- Generates a Dockerfile from an Image
- Searches added filenames for potential secret files
- Extracts files that were added by the Docker ADD/COPY Instructions
- It also displays misc. information such as ports open, the user it runs as and environment variables.
