Docker High Performance

Book Description

Docker is a portable container format that allows you to run code anywhere from your desktop to the cloud. The workflow around Docker makes development, testing, and deployment much easier and much faster. However, it’s essential that you know the best practices most techniques for optimization so Docker can help you deploy your application most effectively.

This comprehensive guide will improve your Docker workflows and will ensure your application’s production environment runs smoothly. It starts with a short refresher on working with Docker, then you will learn how to take this basic knowledge to the next level by optimizing your Docker infrastructure and applications at scale. At the end of the book, we will put the concepts and everything you have learned about Docker’s features into practice by rolling out supplementary monitoring and troubleshooting instrumentation to your infrastructure. All of these things will ensure your application succeeds using Docker.

What you will learn
