Hello,
As you know Docker is an open-source technology that is used to deploy applications through containers. It is a relatively new platform but is constantly updated and features a wide community of users.
Docker is a great tool that solves the age-old dilemma between developers and system administrators – while developers say that an app works on their machines, system admins worry about changing its libraries and requirements. With Docker, that is no longer a problem as it allows a more transparent method of communication.
It is essentially a virtual machine, that lets you run images. With Docker, you don’t need to worry about the requirements and that’s a perfect fit for many VPS projects.
Docker is highly popular among developers and can be installed without any problems in our favorite Linux distribution.
There are two versions of Docker – Docker CE (Community Edition) and Docker EE (Enterprise Edition). If you have a small-scale project, or you’re just learning, you will want to use Docker CE.
In this tutorial, we will show you how to install Docker on Ubuntu 18.04.
The first thing to do is to run the next commands :
sudo apt-get update
sudo apt install docker.io
you will see this in your terminal
You can also chek your Docker's version by using this command :
docker --version
