Overview of this book

No doubt Docker Containers are the future of highly-scalable software systems and have cost and runtime efficient supporting infrastructure. But learning it might look complex as it comes with many technicalities. This is where The Docker Workshop will help you. Through this workshop, you’ll quickly learn how to work with containers and Docker with the help of practical activities.? The workshop starts with Docker containers, enabling you to understand how it works. You’ll run third party Docker images and also create your own images using Dockerfiles and multi-stage Dockerfiles. Next, you’ll create environments for Docker images, and expedite your deployment and testing process with Continuous Integration. Moving ahead, you’ll tap into interesting topics and learn how to implement production-ready environments using Docker Swarm. You’ll also apply best practices to secure Docker images and to ensure that production environments are running at maximum capacity. Towards the end, you’ll gather skills to successfully move Docker from development to testing, and then into production. While doing so, you’ll learn how to troubleshoot issues, clear up resource bottlenecks and optimize the performance of services. By the end of this workshop, you’ll be able to utilize Docker containers in real-world use cases.

Preface

Summary

This chapter demonstrated how Docker allows users to work with images to package their applications together with a working environment to be moved across different working environments. You've seen how Docker uses layers and caching to improve build speed and ensure you can also work with these layers to reserve resources or disk space.

We also spent some time creating a base image with only one layer of our image. We've explored tagging and tagging practices you can adopt in order to counter issues associated with deploying and publishing your images. We also took a look at different ways we can publish our images and share them with other users and developers. We are only just getting started and still have a long way to go.

In the next chapter, we'll be working further with our Dockerfiles to learn how multistage Dockerfiles work. We'll also find more ways in which we can optimize our Docker images for better performance when they're released...
