Virtual Box on Windows while using Docker

The following documentation says:

“Docker is installed and running inside of your local Native Apps Virtual Machine in Virtual Box”

  • Write error when importing large database to docker
  • When run docker-compose up I get python: can't open file '': [Errno 2] No such file or directory
  • docker and jwilder/nginx-proxy http/https issue
  • Answer '29' to apt-get install prompt for xorg
  • Referencing the first argument passed to the docker entrypoint?
  • My Questions:
    Question 1:I am using Windows 7, so is it like when I installed the Docker on my windows machine, there already existed a Virtual Box
    on my Windows machine and the docker got installed inside of the “Local Native Apps Virtual MAchine” which is inside the
    Virtual Box?

    When I installed the docker, the following Oracle VM VirtualBox Manager was also installed:

    Question 2:Basically, I want to work on Linux environment inside the docker, so basically I can pull ubuntu 14.10 image repository and work,
    right? Is it like I can pull another repository over the ubuntu 14.10 and work on it using Linux commands?

    Q1: Yes. The Docker Engine uses Linux-specific kernel features, so to run it on Windows we need to use a lightweight virtual machine (vm). Boot2Docker is a lightweight Linux distribution made specifically to run Docker containers.

    Q2: Yes to the first question mark. No to the second question mark.
    After installing docker, you can launch a container with a base Ubuntu image.

    $ sudo docker run -i -t ubuntu /bin/bash

    here /bin/bash, is to start the Bash shell inside the new container
    Now you are already in a linux environment, and you can start your work here. You don’t need to pull another repository. You can create many containers based on the ubuntu image you are having. If you want to save your work to an image, you could do a commit:

    You can either save or export the image to local for future use.

    • Export is used to persist a container (not an image).
    • Save is used to persist an image (not a container).

      The exported version is slightly smaller. That is because it is flattened, which means it lost its history and meta-data.

    Something good to know: A Docker image is a read-only template. For example, an image could contain an Ubuntu operating system with Apache and your web application installed.Images are used to create Docker containers. Docker containers are similar to a directory. A Docker container holds everything that is needed for an application to run.

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
