Installing Docker in CentOS 7
Instructions for installing Docker Community Edition (CE) in CentOS 7
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 [root@kvmde54-19861 ~]# sudo systemctl status docker Docker.service - Docker Application Container Engine Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled) Active: active (running) since Tue 2020-05-05 15:04:24 MSK; 16s ago Docs: https://docs.docker.com Main PID: 2229 (dockerd) Tasks: 8 Memory: 43.2M CGroup: /system.slice/docker.service └─2229 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/cont...

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.
