Integrating GitHub and Jenkins

After installing Jenkins, we will create our first job and integrate it with GitHub. In this section, as in Figure 8.8, we will focus solely on GitHub and Jenkins. Docker Hub will be discussed a little later.

We will use a simple Python application to count the number of hits on a website. Every time you refresh the page, the counter will increment, resulting in an increase in the number of hits on the website.

• requirments.txt: This file contains the dependencies needed for the application to work properly.
• Dockerfile: This builds the image with the required libraries...
