Docker is a software for automating the deployment and management of applications in an operating system-level virtualization environment. It allows you to package an application with all its environment and dependencies into a container that can be ported to any Linux system with kernel cgroups support and provides a container management environment

    Before installing Docker, update the existing Centos package list:
    ``.shell
    sudo yum check-update

    
    To install the latest version of Docker, you need to consult the official Docker repository  
    To do this, run the command:  
    ``.shell
    curl -fsSL https://get.docker.com/ | sh  
    

    Run the Docker daemon after the installation is complete:
    ``.shell
    sudo systemctl start docker

    Make sure that the daemon starts without errors or warnings:  
    ``.shell
    sudo systemctl status docker  
    

    You will see a message like this:
    ``.shell
    [[email protected] ~]# sudo systemctl status docker

    When we install Docker we get not only the Docker service but also the docker command line utility or the Docker client.


    You can also use our One-Click-Apps for one-click installation to install Docker
    To do so, select the required [VPS] plan(https://fornex.com/ssd-vps) and choose Applications → Docker, to install.
    Please note that this will install Docker on Ubuntu 18.04.
