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 focused on using Docker Compose to design, create, and manage multi-container applications. The complexity of containerized applications has increased with the rise of the microservice architecture. Thus, it has become difficult to create, manage, and troubleshoot multi-container applications without the appropriate tooling. Docker Compose is the official tool in the Docker toolbox for this purpose.

In this chapter, the main focus was to learn docker-compose comprehensively. With this aim, the chapter started with the capabilities of the docker-compose CLI with its commands and flags. Then, the anatomy of docker-compose.yaml files was presented. The power of Docker Compose actually comes from the configuration capabilities defined in the docker-compose.yaml files. Therefore, it is essential to learn how to use these files to manage multi-container applications.

Following that, the configuration of services in Docker Compose was illustrated. You have learned...
