Introduction to Shell Containerization and Virtualization Concepts

1

Using Docker Containers

You'll go from starting and stopping your first container to seeing how to clean your environment by removing all containers and images. You'll see how to debug issues by running commands inside a container or executing bash commands in a container interactively. All of this is done using the Docker Command Line Interface.

Running Docker containers

Running your first container

Running a container in the background

An interactive container

Working with Docker containers

Helping a colleague

Cleaning up containers

Managing local docker images

Pulling your first image

Pulling a specific tag

Cleaning up images

2

Writing Your Own Docker Images

Once you are able to manage images and containers, it's time to know how to share images with colleagues or your entire company and to understand how to create your own. Now, you'll build your own images using Dockerfiles. Dockerfiles are text files that include everything needed for Docker to build an image. You'll learn how to create images and will get an introduction to all the essential Dockerfile instructions like FROM, RUN, COPY, and more. By the end of this chapter, you'll have insight into how Docker makes images and be able to create optimized Docker images from scratch.

Distributing Docker Images

Sharing your work using a Docker registry

Saving an image to a file

Receiving Docker Images

Creating your own Docker images

Building your first image

Working in the command-line

Editing a Dockerfile

Creating your own Dockerfile

Managing files in your image

Copying files into an image

Creating Secure Docker Images

In this final chapter, you’ll focus on making your Dockerfiles configurable and secure. You'll learn how to make your Dockerfiles configurable using the ARG and ENV instructions. You’ll see why changing the user in your images makes them more secure and how to use the USER Dockerfile instruction to do so. To wrap things up, you’ll learn about some essential security best practices when creating Docker Images.
