Introduction to Docker

Overview

Gain an introduction to Docker and discover its importance in the data professional’s toolkit. Learn about Docker containers, images, and more.

Docker is a tool used to develop, run, and ship containers. It’s an essential part of every data professional’s toolbelt, helping to create robust, secure, and scalable applications or workflows.
In this course, you’ll become a Docker pro, gaining hands-on experience using Docker CLI.

Learn the Docker basics and understand how to create and manage containers using Dockerfiles and instructions. You’ll learn the Docker terminology and get hands-on experience with Docker commands using the Docker Command Line Interface.

As you progress, you’ll learn how to create and manage Docker containers using Dockerfiles and Dockerfile instructions. To wrap up, you’ll learn Docker image security best practices to make your images safe and secure.

Syllabus

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.

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.

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.
