How to clone git repo using Dockerfile

I am a beginner to Docker. I have written a small Dockerfile to start with. I am not able to clone my repo using following Dockerfile. 

FROM mattes/hello-world-nginx
RUN apt-get update && apt-get install -y git
RUN git clone https://github.com/umairnow/LocalizableGenerator.git
VOLUME LocalizableGenerator

I am not sure if I am doing it right or do I have to use WORKDIR. I have also tried following but it doesn't clone the repo.

VOLUME ["/data"]
WORKDIR /LocalizableGenerator

Can anyone help please?

If you don't want to install git you can use multi stage builds in your Dockerfile,

FROM alpine/git:latest
WORKDIR /clone-workspace
RUN git clone https://github.com/umairnow/LocalizableGenerator.git

FROM mattes/hello-world-nginx
COPY --from=0 /clone-workspace/LocalizableGenerator /path/to/file

Your git clone does work:

$ docker build . -t test
...
Successfully built 5370e446d719
Successfully tagged test:latest
$ docker run -ti test /bin/bash
root@1377e0a4735d:/# cd LocalizableGenerator/
root@1377e0a4735d:/LocalizableGenerator# git log | head

    Improved get input method. Now user can just drag drop file path or paste file path to generate translation files.

I don't think you want the VOLUME directive though. VOLUME is used to mount a directory from outside your container to the container itself. Here, you already have the directory within the container.

You can clone repo locally (out of docker file) and then use "COPY" or "ADD" instructions to put the code to Docker image. It let you keep image thin without git related software.
