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 has provided hands-on experience integrating your code using the CI/CD pipeline. CI helps developers to integrate code into a shared and easily accessible repository. CD helps developers to deliver the code stored in the repository to production. The CI/CD approach also helps to keep the product up to date with the latest technology and to provide the latest version to customers with a fast turnaround for new features and bug fixes.

Once this chapter's defined three phases of the CI/CD pipeline are completed successfully, you will only need to focus on editing your code on GitHub. Jenkins will then be your automated assistant, and it will automatically handle the rest of the phases for you and make the images available for production.

In the next chapter, you will learn about Docker swarm mode and how to perform service discovery, clustering, scaling, and rolling updates.
