1. Key Docker Concepts

In this section, we'll explore the fundamental concepts of Docker - a powerful tool for managing containers. Understanding these concepts will help you gain a deeper insight into how Docker works and how to effectively utilize it in your software development and deployment processes.

What is Docker?

Containers, Dockerfile and Docker Commands

Installing the Docker Desktop

2. Quick Start

This section will guide you step by step through the process of creating your first Dockerfiles - text files that contain instructions for automating the building of Docker images. You will learn how to create a Dockerfile for your application, including defining the base image, adding necessary components, configuring the environment, and installing dependencies.

3. Docker for Flask

The section titled "Docker for Flask Developers" offers an in-depth exploration of utilizing Docker for developing web applications based on the Flask framework for Python. In this section, you'll learn how to effectively use Docker to create, deploy, and manage Flask applications in an isolated and scalable container environment.

How to use Python Image

We will explore the process of Dockerizing Python applications. Dockerization involves packaging an application into a Docker container, which contains all dependencies and configurations.

The logic of the Dockerfile lies in executing these instructions sequentially.

Compare a Docker Container to Building a Hotel

Choosing a base material (FROM): When building a hotel, the first step is choosing the base material, like bricks or concrete. In Docker, this is akin to selecting a base image, for example, python:3.9-slim, which already contains all the necessary components to run Python programs.

Copying ingredients (COPY): Assembling a hotel involves moving all the necessary items into its premises, like furniture, bedding, and more. In Docker, this is copying all the required program files into the container's internal space.

Indicating actions upon startup (CMD): When the hotel is ready for use, typically, instructions are given to the staff about what to do upon opening the hotel, such as turning on lights in the lobby or starting to welcome guests. In Docker, this is specifying which command should be executed when the container is started, for example, python app.py, to run the main program file.

In the next chapter, we'll build and launch this container.
