Docker Essentials: A Developer Introduction
|
Get started with Docker, the essential tool for developers. Learn how to create, deploy, and manage containers for efficient software development and deployment. Discover the fundamentals of containerization.
At a Glance
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.
