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

So far in this book, we've run our Docker containers and controlled the way they run from the command line using direct commands such as docker run to launch containers. Our next step is to automate things with the use of Docker Compose, which allows an entire environment of containers to work together. Docker Swarm is the next step in managing our Docker environments. Docker Swarm allows you to orchestrate how your containers can scale and work together to provide a more reliable service to your end-users.

Docker Swarm allows you to set up multiple servers running Docker Engine and organize them as a cluster. Docker Swarm can then run commands to coordinate your containers across the cluster instead of just one server. Swarm will configure your cluster to make sure your services are balanced across your cluster, ensuring higher reliability for your services. It will also decide for you which service will be assigned to which server depending on the load across...
