Build reliable connections between your Docker containers.
Docker networking is essential when you start building applications that use multiple containers. Understanding how containers communicate with each other—and with services outside Docker—can help you build applications that are easier to manage, secure, and troubleshoot.
In my LinkedIn Learning course, Docker Networking: Creating, Managing, and Troubleshooting Container Networks, I teach you the fundamentals of networking in Docker and show you how to apply them to real containerized applications.
You’ll explore Docker’s different network types and learn how to choose the right network for your application. From there, you’ll create and manage custom networks, connect containers, and use Docker’s built-in DNS capabilities to simplify communication between services.
Finally, you’ll learn practical troubleshooting techniques for diagnosing common Docker networking problems so you can identify connectivity issues and get your containers communicating again.
What You’ll Learn
- Understand how Docker networking works
- Compare common Docker network types
- Choose the right network for different scenarios
- Create and manage custom bridge networks
- Connect and disconnect containers from networks
- Use Docker DNS for container discovery
- Configure network aliases
- Manage container networks with Docker Compose
- Diagnose and troubleshoot Docker networking issues
Whether you’re working with multi-container applications, microservices, or development environments, this course will help you build a stronger understanding of how Docker containers communicate.
