**The goal for Step 1**: Create a Python Flask image for your
development projects.

We'll continue where you left off from :ref:`Step 5.3. Building a hello world python image <Step 5.3>` by
using the same Dockerfile.

#. Copy your ``hello-world-python`` folder (that contains
   the ``Dockerfile``) to folder ``flask-dev-image``.
   
   .. Note:: You will use this image for labs 6 and 7

   .. code-block:: bash

       cd ~
       cp -r hello-world-python flask-dev-image

#. Navigate to flask-dev-image and build a new image for your Flask
   projects called ``python/flask:dev``.
   
   .. Note:: Make changes to the Dockerfile in this folder for all Flask
       projects

   .. code-block:: bash

       cd ~/flask-dev-image
       docker build -t python/flask:dev .

#. Verify that image was built successfully.

   .. code-block:: bash
