Docker is one of the most popular containerization platforms, allowing you to run applications in isolated environments. Installing Docker on your VPS makes it easy to deploy web applications, databases, APIs, and development environments quickly and efficiently.

Requirements

• Ubuntu 24.04 VPS
• Root or sudo access
• SSH connection to your server

Step 1 — Update Your VPS

sudo apt update
sudo apt upgrade -y

Step 2 — Install Required Packages

sudo apt install ca-certificates curl gnupg lsb-release -y

Step 3 — Add Docker's Official GPG Key

sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

Step 4 — Add the Docker Repository

echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] \
https://download.docker.com/linux/ubuntu \
$(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Step 5 — Install Docker Engine

sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y

Step 6 — Verify Installation

docker --version

Example output:

Docker version 28.x.x

Step 7 — Start Docker

sudo systemctl enable docker
sudo systemctl start docker

Step 8 — Test Docker

sudo docker run hello-world

If Docker is installed correctly, a welcome message will appear.

Optional: Run Docker Without sudo

sudo usermod -aG docker $USER

Log out and log back in for the changes to take effect.

Useful Docker Commands

docker ps
docker images
docker pull nginx
docker stop CONTAINER_ID
docker start CONTAINER_ID
docker rm CONTAINER_ID
