Overview of this book

Kubernetes is an open source orchestration platform for managing containers in a cluster environment. This Learning Path introduces you to the world of containerization, in addition to providing you with an overview of Docker fundamentals. As you progress, you will be able to understand how Kubernetes works with containers. Starting with creating Kubernetes clusters and running applications with proper authentication and authorization, you'll learn how to create high-availability Kubernetes clusters on Amazon Web Services (AWS), and also learn how to use kubeconfig to manage different clusters. Whether it is learning about Docker containers and Docker Compose, or building a continuous delivery pipeline for your application, this Learning Path will equip you with all the right tools and techniques to get started with containerization. By the end of this Learning Path, you will have gained hands-on experience of working with Docker containers and orchestrators, including SwarmKit and Kubernetes. This Learning Path includes content from the following Packt products: • Kubernetes Cookbook - Second Edition by Hideto Saito, Hui-Chuan Chloe Lee, and Ke-Jou Carol Hsu • Learn Docker - Fundamentals of Docker 18.x by Gabriel N.

Chapter 3. Working with Containers

In the previous chapter, you learned how to optimally prepare your working environment for the productive and frictionless use of Docker. In this chapter, we are going to get our hands dirty and learn everything that is important to work with containers. Here are the topics we're going to cover in this chapter:

  • Running the first container
  • Starting, stopping, and removing containers
  • Inspecting containers
  • Exec into a running container
  • Attaching to a running container
  • Retrieving container logs
  • Anatomy of containers

After finishing this chapter you will be able to do the following things:

  • Run, stop, and delete a container based on an existing image, such as NGINX, busybox, or alpine
  • List all containers on the system
  • Inspect the metadata of a running or stopped container
  • Retrieve the logs produced by an application running inside a container
  • Run a process such as /bin/sh in an already-running container.
  • Attach a Terminal to an already-running container
  • Explain in your own...
