Optimizing Docker Image

[rahulsurwade08]

Hey, I went over the Dockerfile and could propose some changes -

1. Replace root user
2. Add Multistage Build
3. Clean Up After Installing Packages
4. Replace latest tag of kalilinux/kali-rolling
5. Update .dockerignore file

@viyatb @7a Let's discuss this further

Expected Behavior

1. Container should run without root user
2. Reduce Docker Image Size

Current Behavior

1. Container is running as root
2. Docker Image size is around 8GB

Possible Solution

1. Add line USER appuser in Dockerfile
2. Add rm -rf /var/lib/apt/lists/*in the cleanup
3. Reduce the scope of ADD . /owtf
   

Context

1. I am trying to implement some security measures and reduce the container size
2. These changes help us by utilizing less space and easy deployments on CSPs
