Udemy – Docker for Java Developers

This course is designed for beginners, and we’ll start right from the basics of what Docker is and why it has become the standard tool for running applications across different environments.

You will learn:

• What Dockerfiles, Docker images, Docker containers, and Docker registries are, and how they all fit together.
• How to install Docker on both Mac and Windows, so you can get started no matter what operating system you use.
• How to use the most commonly used Docker commands to build images, start containers, and manage your applications.

You will learn how to create Dockerfiles step by step, including how to:

• Write a simple Dockerfile to containerize your application.
• Create multi-stage Dockerfiles that make your images smaller and faster.
• Build Docker images and run them as containers.

You will also learn how to manage containers effectively:

• How to start, stop, and inspect containers.
• How to connect your containers so they can talk to each other.
• How to persist and share data using Named Volumes, Anonymous Volumes, Bind Mounts, and tmpfs storage.

You will also learn about Docker networking and how containers communicate on:

• The default bridge network,
• User-defined bridge networks,
• And the host network mode.

Finally, you’ll learn how to work with DockerHub:

• How to find and pull existing images,
• And how to publish your own images so they can be shared with others.

All of this, from the very beginning, to help you confidently start using Docker as a Java developer and take your applications from your laptop to the cloud.
