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

Network Plugins

Docker supports a wide range of networking technologies with the help of Docker networking plugins. Although it supports container-to-container and host-to-container networking with full functionality, the plugins enable us to extend networking to further technologies. The networking plugins implement a remote driver as a part of different network topologies, such as virtual extensible LAN (vxlan) and MAC virtual LAN (macvlan). You can install and enable networking plugins with the Docker plugin commands. Also, you need to specify the name of the network driver with --driver flags. For instance, if you have installed an enabled my-new-network-technology driver and want your new network to be a part of it, you need to set a driver flag:

docker network create --driver my-new-network-technology mynet

This command creates a network named mynet, and the my-new-network-technology plugin manages all networking operations.
