Docker is a popular containerization platform that allows you to quickly deploy and manage applications. Installing Docker on an Ubuntu VPS is a straightforward process. This guide will walk you through the steps.

Step 1: Update the Package Database

  • Before installing any software, it's a good practice to update your package database. Run:

    sudo apt update

Step 2: Install Required Packages

  • Install packages to allow apt to use a repository over HTTPS:

    sudo apt install apt-transport-https ca-certificates curl software-properties-common

Step 3: Add Docker’s Official GPG Key

  • Import the GPG key for Docker:

    curl -fsSL | sudo apt-key add -

Step 4: Add Docker Repository to APT Sources

  • Add the Docker repository to APT sources:

    sudo add-apt-repository "deb [arch=amd64] $(lsb_release -cs) stable"

Step 5: Install Docker CE (Community Edition)

  • Update the package database with Docker packages from the newly added repo:

    sudo apt update
  • Install Docker CE:

    sudo apt install docker-ce

Step 6: Start and Automate Docker

  • Start Docker:

    sudo systemctl start docker
  • Enable Docker to start on boot:

    sudo systemctl enable docker

Step 7: Verify Docker Installation

  • Check that Docker is running:

    sudo systemctl status docker


After completing these steps, Docker will be installed and running on your Ubuntu VPS. You can now begin containerizing applications and deploying them with ease. Remember to regularly update Docker to get the latest features and security updates.
