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

Non-Native Docker Networks

In the final section of this chapter, we will discuss non-native Docker networks. Aside from the native Docker network drivers that are available, Docker also supports custom networking drivers that can be written by users or downloaded from third parties via Docker Hub. Custom third-party network drivers are useful in circumstances that require very particular network configurations, or where container networking is expected to behave in a certain way. For example, some network drivers provide the ability for users to set custom policies regarding access to internet resources, or other defining whitelists for communication between containerized applications. This can be helpful from a security, policy, and auditing perspective.

In the following exercise, we will download and install the Weave Net driver and create a network on a Docker host. Weave Net is a highly supported third-party network driver that provides excellent visibility into container mesh...
