Docker run command from git repo?

Let's say that I have a git repo which contains my new files and docker files (and others) from other git repo.
I want to clone this repo to my own local machine, and then I want to build this repo with docker. So I'll execute 

docker build -t name:v1 cloned-folder/

But, after that, when I type docker images I get two images: name:v1 and image from the repo.

I want only have my image. How to do that without uploading to docker.hub?

Or maybe there is an option to run new container from cloned files without build?

If your Dockerfile starts with "FROM <image>", then docker images will always shows both <image> (the base image) and name:v1.

The fact that the Dockerfile is managed in a git repo is not important.

The OP adds:

git clone URL_to_my_repo and this repo contains repo mentioned earlier with my extra own files.
Then docker build -q -t mynewimage:v1 cloned_folder/.
after that I get two images when I type docker images

  • image from the FROM section of Dockerfile and
    • mynewimage:v1.
      What I want is to have only one image: mynewimage:v1.

That is expected (to see 2 images): your second one is built from the layers of the first one: you need both in order for mynewimage to work (because of the union filesystem).
