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

Managing Docker Containers

Throughout our container journey, we will be pulling, starting, stopping, and removing containers from our local environment quite frequently. Prior to deploying a container in a production environment, it is critical that we first run the container locally to understand how it functions and what normal behavior looks like. This includes starting containers, stopping containers, getting verbose details about how the container is running, and, of course, accessing the container logs to view critical details about the applications running inside the containers. These basic commands are outlined as follows:

  • docker pull: This command downloads a container image to the local cache
  • docker stop: This command stops a running container instance
  • docker start: This command starts a container instance that is no longer in a running state
  • docker restart: This command restarts a running container
  • docker attach: This command allows users to gain...
