Whether you are a DevOps beginner or just a developer who wants to start working with containers, you’re in the right place. Docker is an in-demand technology that you will be exposed to frequently while on the job.

 

Docker is used for setting up, deploying, and running applications, at scale, by containerizing them. More on that later. Docker also provides developers with a consistent environment for product development, and along with Kubernetes, makes managing the development lifecycle a breeze.

 

In this course, you will learn the fundamentals of Docker such as containers, images, and commands. You’ll then progress to more advanced concepts like connecting to a database container and how to simplify workflows with Docker Compose. At the end, you’ll learn how to monitor clusters and scale Docker services with Swarm.

Working with Containers: Docker & Docker Compose

Installing Docker on a Linux system is always interesting, however, I will cover installation for only Ubuntu. For other different versions of Linux, you can check out the following links below: 

**CentOS installation** : https://docs.docker.com/install/linux/docker-ce/centos/

**Debian**: https://docs.docker.com/install/linux/docker-ce/debian/

**Fedora**: https://docs.docker.com/install/linux/docker-ce/fedora/

# Docker CE on Ubuntu

To install Docker Engine - Community, you need the 64-bit version of one of these Ubuntu versions:

- Disco 19.04
- Cosmic 18.10
- Bionic 18.04 (LTS)
- Xenial 16.04 (LTS)

That's all you need. There aren't many complex requirements.
