Setting up Docker on an Ubuntu VPS

Containerization has become an integral part of modern software development. Docker is one of the most popular tools for managing containers. This article will guide you through setting up Docker on a Virtual Private Server (VPS) running Ubuntu.

Step 1: Installing Docker

Before installing Docker on your Ubuntu VPS, update the package list:

sudo apt update

After this, execute the following commands to install the Docker Engine:

sudo apt install -y docker.io

To verify the successful installation of Docker, run the following command:

VPS Hosting

Servidores virtuales con recursos garantizados

Elegir VPS

docker --version

Step 2: Starting the Docker Service

To start the Docker service and configure it to automatically start after server reboot, execute these commands:

sudo systemctl start docker sudo systemctl enable docker

The Docker service will now start automatically on each server reboot.

Step 3: Adding Your User to the Docker Group

To use Docker without administrative privileges, add your user to the Docker group:

sudo usermod -aG docker $USER

For the changes to take effect, either log out and back in, or execute the following command:

su - $USER

Step 4: Testing Docker

To verify the correct installation and configuration of Docker on your Ubuntu VPS, run the following command to download and run the Hello World container:

docker run hello-world

If you see the message «Hello from Docker!», then Docker is correctly installed and running on your Ubuntu VPS.

You are now ready to use Docker on your server. Enjoy the convenience and flexibility of containerization in your project!
