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

Working with Container Resources

One of the main benefits of moving to Docker from a traditional server environment is that it enables us to heavily reduce the footprint of our services and applications, even when moving to production. This doesn't mean we can simply run anything on our container, expecting all the processes to simply complete their execution, however. Just as we would need resources with a service running on a standalone server, we need to ensure that the resources (such as CPU, memory, and disk input and output) that are being used by our containers do not cause our production environments or any other containers to crash. By monitoring the resources used in our development system, we can help optimize processes and ensure that the end-user is experiencing seamless operation when we move it into production.

By testing our services and monitoring resource usage, we will be able to understand the resources required by the running applications and ensure that...
