Practical Docker for developers: Managing Containers, Images, and Registries

Course Description

This course dives deep into the practical, day-to-day usage of Docker for software developers. You will learn how to efficiently manage containers, master the art of building custom Docker images tailored to your applications, and effectively use registries like Docker Hub to store and distribute them. Through a series of hands-on labs, you'll move from theory to practice, covering the entire container lifecycle and culminating in setting up a multi-container application stack. This course is designed to empower you to seamlessly integrate Docker into your development workflow, enhancing your application's portability and reliability.

Who is this course for

This course is specifically designed for developers who want to become proficient in using Docker for their projects. It's a perfect fit for:

• Software Developers (Backend, Frontend, Full-Stack): Who want to containerize their applications for consistent development and deployment environments.

• Engineers new to containerization: Who have a basic understanding of Docker and want to learn how to apply it practically in their daily work.

• DevOps Professionals: Who want to solidify their understanding of the developer experience with Docker.

Course Objectives

Upon successful completion of this course, you will be able to:

• Understand Docker Images: Explain the concept of Docker image layering and immutability.

• Manage Container Lifecycles: Confidently create, start, stop, restart, and remove Docker containers.

• Interact with Containers: Run containers in interactive mode and manage processes running inside them.

• Use Docker Registries: Create a Docker Hub account, pull public images, and push your own custom images.

• Build Multi-Service Applications: Set up a complete application environment, such as a MySQL database with a phpMyAdmin interface, using multiple linked Docker containers.
