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

Creating Base Docker Images

Creating your base Docker image is actually straightforward. Just as we used the docker commit command previously to create an image from a running container, we can also create an image from a system or server we have originally been running our applications on. We need to remember that creating a base image still needs to remain small and lightweight. It is not simply a matter of moving existing applications running on existing servers over to Docker.

We could use the system we are specifically working on, but if you are using a production server, the image could actually be pretty big. If you have a small virtual machine you would think is perfect for a base image, you could use the following steps to create a base image from it. Similar to the docker commit command, this can be used for any system you can access.

Exercise 3.03: Creating Your Base Docker Images

The following exercise will use the basic-app image we are currently running and...
