Step 4: Test the Python application locally That's good enough for our demonstration. This is a very simple HTTP server, running on port 8000. Httpd = socketserver.TCPServer(('', PORT), Handler) Write the Python code to run as the HTTP serverД¬reate a file named web.py with the following contents: # This content will be returned by our web service. That means it'll display nicely in a browser.Д¬reate a file named index.html with the following contents: Hello, Red Hat Developers World from Python! Typically, a web service will return data as a JSON document, but for this demonstration, we'll be returning HTML. Set up a directory for the Python projectДЇirst, create a directory and move into it with the following commands: mkdir firstpython & cd firstpython Create the HTML file Let's get started with our Python web service.

See his tutorial Build your first application using Python 3.5 on RHEL 7 with containers and Red Hat Software Collections if you need instructions for building a Python application on RHEL 7. Note: I'm borrowing the code for this article from my colleague Mike Guerette.

The Dockerfile build instructions to build the container image.

The Python code to run as the HTTP server.

It will run on port 8000 and return a 'Hello world'-type message. Now it's time to create a simple Python HTTP server that will act as our very basic web service. Also, every podman instance in this article can be replaced with docker they're command-for-command compatible. Note: If you really feel the need to run docker commands, you can always use alias docker='podman'. Figure 2: The containerized application running in a local system. You'll see output like the screenshot in Figure 2. Enter the following command to see it run: podman run hello-world You can use the Docker 'Hello World' example to see a containerized application running on your local system. You can run podman -version to verify that it exists. Podman is the open source alternative to Docker that does not run as root, which improves security.

That's right, there's no need to install Docker on RHEL 8 because Podman is included automatically. Step 2: Don't install Docker (you don't need to) You can see a complete list by running the yum module info python39 command. For example, the Python3.9 module includes development tools like numby, pip, setuptools, scipy, and many more. A module is a streamlined way to get all the components you would typically need for a particular deployment. Modules were introduced with RHEL 8 as part of the new Application Streams concept. Notice that we installed a module, the yum module. Figure 1: Start using Python 3.9 in your local environment. Now you can start using Python via the python3.9 command, as shown in Figure 1. Use the following commands to install Python 3.9 on your RHEL 8 machine: Creating a Python containerized application on a machine without Python support might not be ideal, but it is possible. The amazing thing about building and using a Linux container with Python is that you don't actually need Python on your machine to do it. The whole process should take about 15 minutes.

This article shows you how to install Python 3.9, set up your environment, and use it to create and run a Python web service on Red Hat Enterprise Linux (RHEL) 8.

Setting up your Python 3.9 development environment in a Linux containerВ is quick and easy.
