Docker: Clone git repo in current directory

Question

I am using docker to clone a public repository. It's cloned successfully. But I don't know where its cloned? Also how can I clone the repo in my current working directory using docker?

Dockerfile

FROM debian:stretch

RUN apt-get update
RUN apt-get install -y git
RUN git clone https://github.com/ishpreet-singh/Sudoku.git

Terminal

root@ubuntu:/home/hp1/Desktop/src/sample# docker build -t img2 .

Answer 1

The repository will be cloned to the WORKDIR directory which defaults to /.

So after logging into container you'll find the cloned repository under /Sudoku.

Cloning a git repo using docker seems to be a strange scenario? Why would one do that?
