Let's add the following lines of code to our app.py: from flask import Flask You can find a detailed guide on how to create or install this project here.Īssuming you followed the installation instructions correctly and have an active virtual environment with Flask installed, we will now modify the two files created in the GitHub readme as follows. In this section, we'll go over how to create an application with a structure similar to the one shown above. (Source: ) How to Set Up the Project Basic directory structureĪfter completing the following steps, our application directory structure will look like this: The instructions in this file are executed by the user on the command line interface in order to create an image. In order for Docker to build images automatically, a set of instructions must be stored in a special file known as a Dockerfile. What is Docker?ĭocker is a tool that makes it easier to create, deploy, and run applications using containers.Ī docker container is a collection of dependencies and code organized as software that enables applications to run quickly and efficiently in a range of computing environments.Ī docker image, on the other hand, is a blueprint that specifies how to run an application. What is Flask?įlask is a popular Python micro web framework that helps you develop lightweight web applications and APIs quickly and easily.Īs a web framework, it provides greater flexibility, customization, and scalability for simple web applications while remaining highly compatible with cutting-edge technologies. You'll also learn a few Docker commands that are commonly used. For the demonstration, we'll use Flask as our web framework and Docker for image creation and containerization. This article will show you how to make a basic Docker image and run it as a container. It significantly reduces how long it takes to get from writing code to running it in production. With Docker, you can now easily ship, test, and deploy your code quickly while maintaining full control over your infrastructure. And fortunately, there's a tool that helps you do that – Docker. These days, developers need to develop, ship, and run applications quicker than ever.
