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.

Summary

In this chapter, you learned the fundamentals of containerization, the benefits of running applications in containers, and the basic Docker life cycle commands to manage containerized instances. You learned that containers serve as a universal software deployment package that truly can be built once and run anywhere. Because we are running Docker locally, we can know for certain that the same container images running in our local environment can be deployed in production and run with confidence.

Using commands such as docker run, docker start, docker exec, docker ps, and docker stop, we have explored the basics of container life cycle management through the Docker CLI. Through the various exercises, we launched container instances from the same base image, configured them using docker exec, and cleaned up the deployments using other basic container life cycle commands such as docker rm and docker rmi.

In the final portion of this chapter, we jumped in head-first, taking...
