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

Dockerfile Best Practices

In the previous section, we discussed how we can build an efficient Docker image with multi-stage Dockerfiles. In this section, we will cover other recommended best practices for writing Dockerfiles. These best practices will ensure reduced build time, reduced image size, increased security, and increased maintainability of the Docker images produced.

Using an Appropriate Parent Image

Using the appropriate base image is one of the key recommendations when building efficient Docker images.

It is always encouraged to use official images from the Docker Hub as the parent image when you are building custom Docker images. These official images will ensure that all best practices are followed, documentation is available, and security patches are applied. For example, if you need the JDK (Java Development Kit) for your application, you can use the openjdk official Docker image instead of using the generic ubuntu image and installing the JDK on top of...
