Docker for Python Developers

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

Docker Images

Installing the Docker Desktop

Docker Hub

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.

How to use Python Image

Building and Running

Installing Libraries

Challenge 1: Requirements

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.

4. Advanced Concepts

This section delves into Docker Compose, a tool designed to simplify the management of multi-container Docker applications. By utilizing Docker Compose, users can define and run multi-container Docker applications with ease, streamlining the process of container orchestration.

Users

Docker Compose

Challenge 3: Docker Compose

Task

Clone this repository to explore this project:

Fill in all the blanks ( ___ ) in the Docker Compose file (docker-compose.yml) to configure the web application container. Use parameters to define the build context (build), set ports (ports), mount volumes (volumes), and execute a command (command).

To check the task, run the command below:

If the command above doesn't work, try inputting this python3 tests/run.py.

Run the commands below to build the container and start it:

Navigate in the browser to port 0.0.0.0:8000.
