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

Introduction

The previous chapter on security covered some best practices for Docker images and services that have adhered to these best practices. We made sure that our images and services were secure and that they limited what could be achieved if an attacker was able to access the image. This chapter will not only take you through the best practices in creating and running our Docker images, but will also focus on container performance, configuring our services, and ensuring that the services running on them are running as efficiently as possible.

We will start this chapter with an in-depth look at how you can both monitor and configure the resources being used by your services, such as memory and CPU usage. We will then take you through some important practices that you can implement in your projects, looking at how you create your Docker images and the applications that are running on them. Lastly, this chapter will give you some practical tools to use to test your Dockerfiles...
