How To Install Docker on Ubuntu 18.04 LTS

Install Docker on Ubuntu 18.04 LTS

In this tutorial, we will show you how to install Docker on your Ubuntu 18.04 LTS. For those of you who didn’t know, Docker is an open-source project that automates the deployment of applications inside the software container. The container allows the developer to package up all project resources such as libraries, dependencies, assets, etc. Docker is written in the Go Programming language and is developed by Dotcloud. It is basically a container engine that uses the Linux Kernel features like namespaces and control groups to create containers on top of an operating system and automates the application deployment on the container.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Docker on Ubuntu 18.04 Bionic Beaver.


  • A server running one of the following operating systems: Ubuntu 18.04, and any other Debian-based distribution like Linux Mint.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Docker on Ubuntu 18.04 LTS Bionic Beaver

Step 1. First, make sure that all your system packages are up-to-date by running the following apt-get commands in the terminal.

sudo apt-get update
sudo apt-get upgrade

Step 2. Installing Docker on Ubuntu 18.04.

  • Method 1. Install Docker from Ubuntu Repository.
apt-get install

Wait until the installation has been completed, start, and enable Docker service:

systemctl start docker
systemctl enable docker

Verify docker version:

### docker --version
Docker version 17.03.2-ce, build f5e46e2
  • Method 2. Install Docker from the Official Docker Repository.

First, you need to install the prerequisite dependencies:

apt-get update
apt-get install apt-transport-https ca-certificates curl software-properties-common

Create a new file for the Docker repository:

### nano /etc/apt/sources.list.d/docker.list
deb [arch=amd64] bionic stable

Next, you need to add Docker’s GPG key:

curl -fsSL | sudo apt-key add -

Once, that’s imported, update Apt again:

apt-get update

Step 3. Installing Docker CE.

Now install Docker CE with the apt command:

apt-get install docker-ce

Check for the docker version:

$ docker --version
Docker version 18.03.0-ce, build 0330e24

To check whether docker is running or not, type the following command:

systemctl status docker
