Description

With the advent of the microservices architecture pattern and enabling technologies such as containers, the way applications are being architected and delivered is changing. Packaging software applications into read-only template images in order to derive immutable application containers, is a key ingredient in this approach, and Docker is at the forefront. In this course, Containerizing a Software Application with Docker, you'll learn how to package a software application into a Docker image. First, you'll explore the nature of Docker images, and their relationship with containers. Next, you'll master how to create Docker images, including authoring a Docker image for a real software application using a Dockerfile. Finally, you'll discover how to name and share Docker images with a wider audience. By the end of this course, you'll have gained the required knowledge of techniques and best practice to get started with containerizing your own software applications.

Course Overview
Hi everyone, my name is Nigel Brown, and welcome to my course, Containerizing a Software Application with Docker. I'm an independent consultant and trainer, with more than a few years of getting my hands dirty. My current obsession is the evolving world of containers and software application delivery. Containers and the Docker platform in particular are helping to revolutionize the way we deliver software applications. Organizations large and small across the globe are adopting a microservices-based container-driven approach to software delivery. In this course using best practice, you're going to learn how to package a software application into a container template, the Docker image. Some of the major topics that we'll cover include the anatomy of a Docker image, and how it relates to image size, techniques for building Docker images, including multistage builds, authoring an image for a software application using the declarative Docker file, and naming and sharing Docker images for wider consumption by users or automation tools. We can't turn you into a ninja Docker author over night, but when you're done with the course, you'll have sufficient knowledge and understanding to get started with containerizing your own software applications with Docker. Ideally before beginning the course, you should be familiar with the basic concepts of container virtualization. If you are just starting on the journey from traditional application packaging to a more modern distributed approach, then join me to discover how to containerize a software application with Docker.
