Introduction to Docker

Docker is an open source tool designed to make it easier for software developers to create, deploy, and run applications with the help of containers. By using it developers can focus on the code they are writing and not think about whether the software will work on the system it will be running on. This is due to the fact that, with Docker, they can package an application with everything it needs, such as libraries and other dependencies.

It is popular among developers and system administrators, making it a common element of DevOps toolchains. And because it is open source, there are already a lot of programs designed to run in a Docker container. During our training we will be covering the fundamental concepts and practices of containerization and container orchestration in order to offer participants an introduction to Docker as well as the pros and cons of containerization.
