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

The Kubernetes API and Access

The Kubernetes API is the fundamental building block of the Kubernetes system. It is the home for all communication between the components in the cluster. External communication, such as user commands, is also executed against the Kubernetes API as REST API calls. The Kubernetes API is a resource-based interface over HTTP. In other words, the API server is oriented to work with resources to create and manage Kubernetes resources. In this section, you will connect to the API, and in the following section, you will start working with Kubernetes resources, including, but not limited to, Pods, Deployments, Statefulsets, and Services.

Kubernetes has an official command-line tool for client access, named kubectl. If you want to access a Kubernetes cluster, you need to install the kubectl tool and configure it to connect to your cluster. Then you can securely use the tool to manage the life cycle of applications running the cluster. kubectl is capable of essential...
