How to Use Docker with Python in Just 10 Minutes

Sometimes you just want to dip your toe into a potentially deep and complex subject. Maybe you only have 10 minutes to spare and you want to get something up and running quickly.

In just 10 minutes, you will be able to say: ‘Oh yes, I’ve used Docker with Python’.

Install Docker

This is as simple as going to: https://www.docker.com/get-started, downloading, and running the installer for your system.

One Folder, Two Files

Open up a terminal window and create a folder for your project:

$ mkdir hello-world
$ cd hello-world

In your favorite editor create two files (app.py & Dockerfile) in this folder:

and

Now in the terminal type:

$ docker image build -t hello-world .

This will use the Dockerfile to create an image tagged

-t

hello-world

.

/usr/src/app

Now, all we need to do is run the image:

$ docker run hello-world

Which should give an output:

Hello World

Congratulations you have just used Docker with Python!
