LinkedIn – Docker: Build and Optimize Docker Images 2025-8

Docker: Build and Optimize Docker Images. This intermediate course teaches you how to build and optimize Docker images to increase build speed and minimize final size. Instructor Shelley Benhoff explains Docker’s layered architecture and caching mechanisms, showing how these key concepts impact performance. The course begins by introducing the difference between images and containers and the importance of optimization, then moves on to building custom images and managing them through tagging and working with repositories. It then moves on to more advanced topics such as layer management, intelligent use of caching to eliminate redundant files, and best practices for writing a safe and efficient Dockerfile (including choosing the right base image and optimal command composition). A key part of the course is learning how to build multi-stage builds to create extremely lightweight final images. Finally, participants will learn troubleshooting techniques and common errors in the image creation process. The end result of this course is the ability to create images that are small, secure, and maintainable, meeting industry standards.

What you will learn

• Understanding image structure: You will learn how Docker builds and layers images.
• Image Optimization: You will learn how to optimize images to reduce size and increase build speed.
• Using Dockerfile: You will learn best practices for writing an efficient and secure Dockerfile.
• Multi-step builds: You will learn how to use multi-step builds to create lightweight final images.
• Troubleshooting Images: You will learn basic techniques for fixing common errors in the image creation process.

This course is suitable for people who:

• Want to improve their understanding of Docker to an intermediate level.
• They are looking to optimize their build processes and reduce the size of their images.
• They aim to create maintainable and secure images based on industry standards.
• Want to learn best practices for writing Dockerfiles and using caching capabilities.
