How to Install Docker on a VPS?

Docker is a powerful tool for managing containerized applications. Installing Docker on a VPS allows you to quickly deploy and scale applications in isolated environments. In this article, we’ll show you how to install Docker on a virtual server.

Step 1: Update the System

Before installing Docker, it’s recommended to update your system. To do this, run the following command:

sudo apt-get update sudo apt-get upgrade

Step 2: Install Necessary Packages

Installing Docker requires certain packages. Execute the following commands:

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

Step 3: Add the GPG Key for the Docker Repository

Add the GPG key to verify the authenticity of the Docker packages:

VPS Hosting

Virtual servers with guaranteed resources

Choose VPS

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Step 4: Add the Docker Repository to the Package Sources List

Add the Docker repository to the list of package sources:

sudo add-apt-repository \ "deb [arch=amd64] https://download.docker.com/linux/ubuntu \ $(lsb_release -cs) \ stable"

Step 5: Install Docker

Now, install Docker using the following command:

sudo apt-get update sudo apt-get install docker-ce

Step 6: Add User to the Docker Group

Add your user to the Docker group to avoid using sudo every time you run Docker:

sudo usermod -aG docker $USER

Now you can restart the system for the changes to take effect. Congratulations, you have successfully installed Docker on your VPS!
