Learning Docker

Handling Docker Containers

In the previous chapter, we explained the stimulating and sustainable concepts that clearly articulated Docker's way of crafting futuristic and flexible application-aware containers. We discussed all the relevant details of bringing Docker containers into multiple environments (on-premise as well as off-premise). You can easily replicate these Docker capabilities in your own environments to get a rewarding experience. Now, the next logical step for us is to understand container life cycle aspects in a decisive manner. You are to learn the optimal utilization of your own containers as well as those of other third-party containers in an efficient and risk-free way. Containers are to be found, accessed, assessed, and leveraged toward bigger and better distributed applications.

In this chapter, we will dig deeper and describe the critical aspects of container handling at length. A number...

Clarifying Docker terms

For substantially simplifying the understandability of this chapter and for minimizing any kind of ambiguity, frequently used terms are explained in the following section.

Docker images

A Docker image is a collection of all the files that make up an executable software application. This collection includes the application plus all the libraries, binaries, and other dependencies such as the deployment descriptor, just needed to run the application everywhere without hitch or hurdle. These files in the Docker image are read-only and hence the content of the image cannot be altered. If you choose to alter the content of your image, the only option Docker allows is to add another layer with the new changes. In other words, a Docker image is made...

Working with Docker images

In the previous chapter, we demonstrated the typical Hello World example using the
hello-world image. Now, there is a need for a closer observation of the output of the docker pull subcommand, which is the de facto command to download Docker images. Now, in this section, we will use the busybox image, one of the smallest but a very handy Docker image, to dive deep into Docker image handling:

If you pay close attention to the output of the docker pull subcommand, you will notice the Using default tag: latest text. The Docker image management capability (the local image storage on your Docker host or on a Docker image registry) enables storing multiple variants of the Docker image. In other words, you could use tags to version your images.

By default, Docker always uses the image that is tagged as latest. Each image variant can be directly identified by qualifying it with an appropriate...

Working with an interactive container

In the first chapter, we ran our first Hello World container to get a feel for how the containerization technology works. In this section, we are going to run a container in interactive mode. The docker run subcommand takes an image as an input and launches it as a container. You have to pass the -t and -i flags to the docker run subcommand in order to make the container interactive. The -i flag is the key driver, which makes the container interactive by grabbing the standard input (STDIN) of the container. The -t flag allocates a pseudo-TTY or a pseudo Terminal (Terminal emulator) and then assigns that to the container.

In the following example, we are going to launch an interactive container using the ubuntu:16.04 image and /bin/bash as the command:

$ sudo docker run -i -t ubuntu:16.04 /bin/bash  

Since the ubuntu image has not been downloaded yet, if we use the docker pull...

Summary

In this chapter, we described required insights in the post-implementation phases, primarily regarding the operational aspect of Docker containers. We started the chapter by clarifying important terms, such as images, containers, registry, and repository, in order to enable you to acquire an unambiguous understanding of the concepts illustrated thereafter. We explained how to search for images in the Docker repository. We also discussed the operation and handling of Docker containers, how to track changes inside containers, and how to control and housekeep containers. In the next chapter, we will explain promising and potential techniques and tools for building Docker images in an easy-to-grasp manner.

Key benefits

  • • This up-to-date edition shows how to leverage Docker’s features to deploy your existing applications
  • • Learn how to package your applications with Docker and build, ship, and scale your containers
  • • Explore real-world examples of securing and managing Docker containers

Description

Docker is an open source containerization engine that offers a simple and faster way for developing and running software. Docker containers wrap software in a complete filesystem that contains everything it needs to run, enabling any application to be run anywhere – this flexibily and portabily means that you can run apps in the cloud, on virtual machines, or on dedicated servers. This book will give you a tour of the new features of Docker and help you get started with Docker by building and deploying a simple application. It will walk you through the commands required to manage Docker images and containers. You’ll be shown how to download new images, run containers, list the containers running on the Docker host, and kill them. You’ll learn how to leverage Docker’s volumes feature to share data between the Docker host and its containers – this data management feature is also useful for persistent data. This book also covers how to orchestrate containers using Docker compose, debug containers, and secure containers using the AppArmor and SELinux security modules.

Who is this book for?

This book is ideal for developers, operations managers, and IT professionals who would like to learn about Docker and use it to build and deploy container-based apps. No prior knowledge of Docker is expected.

What you will learn

  • • Develop containerized applications using the Docker version 17.03
  • • Build Docker images from containers and launch them
  • • Develop Docker images and containers leveraging Dockerfiles
