These are very quick instructions for installing Docker under Mac OSX and for running Tensorflow on it. This is a summarized version of the longer explanations given on the official TensorFlow Install page:

• https://www.tensorflow.org/get_started/os_setup#test_the_tensorflow_installation

and the Docker Install page:

• https://docs.docker.com/docker-for-mac/

Install Docker

• Go there: https://docs.docker.com/docker-for-mac/
• Download
• Click on the package (do not worry about the warning)

Run Docker

• Find Docker in the Applications and run it
• It will open a Terminal window
• Note the IP that is specified at the end (should be http://192.168.99.100/)

                        ##         .
                  ## ## ##        ==
               ## ## ## ## ##    ===
           /"""""""""""""""""\___/ ===
      ~~~ {~~ ~~~~ ~~~ ~~~~ ~~~ ~ /  ===- ~~~
           \______ o           __/
             \    \         __/
              \____\_______/


docker is configured to use the default machine with IP 192.168.99.100
For help getting started, check out the docs at https://docs.docker.com

• Quick Docker by pressing Ctrl-C twice and return to the command line

Install TensorFlow "in" Docker

• Run the following command at the prompt, in the same Terminal session:

docker run -it -p 8888:8888 gcr.io/tensorflow/tensorflow

This will download tensorflow and will take a few minutes (~ 8 minutes)

• Make a note of the URL that is given. It will be of the form:

 http://localhost:8888/tree?token=someLongSeriesOfHexadecimalDigits

Create a Script to Start Docker Automatically

If you are using a Mac or Linux machine, create a script called startDocker.sh in your bin directory:

#! /bin/bash

docker run -it -p 8888:8888 gcr.io/tensorflow/tensorflow

Start Jupiter

Jupiter is an application that runs in a browser and presents the user a virtual disk where the user can create folders and write programs.

• To start the Jupiter connected to Docker, open your browser and enter the URL that was given to you in the previous step.

http://localhost:8888/tree?token=someLongSeriesOfHexadecimalDigits

If you get an error message, replace localhost by the IP given next to the whale logo, above (I got 192.168.99.100 when I started Docker).

http://192.168.99.100:8888/tree?token=someLongSeriesOfHexadecimalDigits

• You should end up with a window similar to this one:

• Double-click on the 1_hello_tensorflow.ipynb Jupiter notebook to open it.
• You may get an error when the notebook opens. Just click on Cell then Run All to get rid of the error.
• If the page appears without errors, then all the Tensorflow mini-programs will have run without errors, and you're all set!

Using Jupiter

• Here's a quick tutorial on using the Jupyter dashboard.
