For this simple application, Docker is going to: This file is a set of instructions Docker will use to build the image. In the hello-python/app directory, create a file named Dockerfile with the following contents and save it: FROM python:3.7 Now that you have verified the source code works, the first step in containerizing the application is to create a Dockerfile. This will start a development web server hosting your application, which you will be able to see by navigating to Because port 5000 is the default port for the development server, we didnвЂ™t need to specify it.

Manually run the installer and application using the following commands: pip install -r requirements.txt Note: When you start writing more advanced Python, you'll find it's not always recommended to use pip install and may want to use virtualenv (or pyenv) to install your dependencies in a virtual environment.

The requirements.txt file contains the list of packages needed by the main.py and will be used by pip to install the Flask library. You can learn more about Flask on the Flask website. If you look at the main.py file, youвЂ™ll see the application prints out a hello message. There are only two files in this directory.

Use git to clone the repository to your local machine: git clone Д¬hange to the app directory: cd hello-python/app Otherwise, you can skip to the 'Create a Dockerfile' section. The sample application used is a very simple Flask web application if you want to test it locally, youвЂ™ll need Python installed. In this section youвЂ™ll take some source code, verify it runs locally, and then create a Docker image of the application.

A Kubernetes service - I'm using Docker Desktop with Kubernetes in this walkthrough, but you can use one of the others.

Create a deployment and run the application in Kubernetes.

Create an image and run the application in Docker.

Get the code and run the application locally.

This walk-through assumes you are a developer or at least comfortable with the command line (preferably bash shell).

In this blog youвЂ™ll walk through how to containerize an application and get it running in Kubernetes. Or maybe youвЂ™re getting started but still donвЂ™t know what you donвЂ™t know. So, you know you want to run your application in Kubernetes but donвЂ™t know where to start. Author: Jason Haley (Independent Consultant)
