Docker Essentials: A Developer Introduction
Learn how to use containers for your applications. Create and run your first Docker container. Then, learn how to run containers in production and solve problems of orchestration such as high availability, service discovery, and reconciliation.
About this course
Docker is a development tool and a virtualization technology used to automate the deployment of applications inside software containers. A container on the other hand is a standard way to package an application that contains all the configuration files, and other dependencies to operate the application. Containers work by isolating the application inside the container so that everything outside the container can be standardized.
Docker has provided a set of tools to simplify the use of containers. This has led to massive adoption of containers by developers and operators. In this course, you will focus mostly on Docker container technologies.
In this course, you’ll follow a series of hands-on labs that demonstrate how to use containers for your applications. You’ll start with the basics: creating and running your first Docker containers. By the end of the course, you’ll get a brief introduction to running containers in production with the and how to solve problems of advanced orchestration such as high availability, service discovery, and reconciliation.
