Tremendous free resource for learning the foundations of Docker and Microservices for full stack development.
This course consists of readings, quizzes, exercises, and guided projects where you practice the basics of containers and Docker Compose, and convert Express and Python documents to microservices with Docker.
Each section contains quizzes to ensure you’ve grasped the material, along with hands-on practice executing an attack on vulnerable code, along with step by step instructions to mitigate the attack. This frequent practice is incredibly valuable for making your knowledge more tangible.
The topic coverage is just thorough enough to get you started working with Docker. Often in the curriculum, the authors provide links to supplemental materials -- these are important for gaining a deep understanding of Docker and working with containers. After taking this course, you'll have a solid understanding of the fundamentals, and will be ready to learn more advanced topics.
Docker is a platform that simplifies the process of developing, deploying, and running applications. It uses containerization technology to package an application and its dependencies into a standardized unit called a container. These containers can run consistently across different environments, making it easier for developers to build, test, and deploy applications, while also enhancing scalability and resource efficiency.
Docker is among the most popular developer tools according to Stack Overflow's 2023 Developer Survey, so it's an essential skill to learn and will greatly enhance your ability to work on modern large-scale applications.
To get started with Docker professionally, focus on these foundational topics:
These foundational topics will give you a strong start in working with Docker. As you gain experience and progress in your career, you can then delve into more advanced topics such as container orchestration (Kubernetes), monitoring, and advanced security configurations. These advanced topics are typically necessary when working on larger-scale and production-grade applications. Start with the basics, build your skills, and expand your Docker knowledge as needed for your specific projects and roles.
Docker is a fairly accessible technology even for beginners.
This guide is specifically written for aspiring and practicing full stack developers, so we do recommend that in your full stack developer journey, that you learn Docker after learning frontend development with HTML, CSS, JavaScript, and a JavaScript framework like React, Angular, or Vue, along with the foundations of a full stack language like Node or Python, and how to work with RESTful APIs.
Besides those topics, having some basic knowledge of the following concepts can be helpful, but again aren't required:
Linux Basics: Docker relies on Linux containers, so having a basic understanding of Linux commands, file systems, and permissions is advantageous.
Command Line Interface (CLI): Familiarity with the command line interface (CLI) is important, as you'll be using Docker commands to create and manage containers.
Networking: Basic knowledge of networking concepts, such as IP addresses and ports, can be beneficial when working with Docker's networking features.
Version Control: Familiarity with version control systems like Git is helpful for managing Docker configurations and images.
Containers and Virtualization Concepts: Having a high-level understanding of containerization and virtualization concepts can aid in grasping Docker's purpose and benefits. Most tutorials will cover this at a high level when introducing Docker.
