How to Set Up Docker on Vultr: Complete Guide 2026

Docker has revolutionized how developers deploy applications. In this comprehensive guide, we'll walk you through setting up Docker on Vultr's high-performance VPS infrastructure, enabling you to deploy containerized applications with confidence.

Why Use Docker on Vultr?

Vultr provides an ideal foundation for Docker deployments. Their global infrastructure with 32 data centers worldwide ensures your containers run close to your users. Combined with SSD-based storage and competitive pricing starting at just $5/month, Vultr offers excellent value for containerized applications.

Key benefits include:

• Lightning-fast SSDs - Docker images load instantly
• Global presence - Deploy containers closer to your users
• Flexible pricing - Pay only for what you use
• One-click deployments - Get started in minutes

Prerequisites

Before we begin, ensure you have:

• A Vultr account (sign up at vultr.com)
• A Vultr VPS instance running Ubuntu 20.04 or later
• SSH access to your server
• Basic command line knowledge

Step 1: Deploy Your Vultr Server

First, let's create a Vultr VPS instance optimized for Docker:

1. Log in to your Vultr dashboard
2. Click "Deploy New Server"
3. Choose "Cloud Compute" as the server type
4. Select your preferred location (choose one closest to your users)
5. Choose "Ubuntu 22.04 LTS" as the operating system
6. Select a plan (we recommend at least 2GB RAM for Docker)
7. Click "Deploy Now"

Wait 2-3 minutes for your server to provision. Once ready, you'll receive an email with your server credentials.

Step 2: Connect to Your Server

Open your terminal and connect to your Vultr server via SSH:

ssh root@your_server_ip

Replace your_server_ip with your actual server IP address. You'll be prompted for your password.

Step 3: Install Docker on Ubuntu

Now let's install Docker on your Vultr server. We'll use the official Docker repository for the latest version:

# Update package index
sudo apt update

# Install prerequisites
sudo apt install -y ca-certificates curl gnupg lsb-release

# Add Docker's official GPG key
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

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

# Update package index again
sudo apt update

# Install Docker Engine
sudo apt install -y docker-ce docker-ce-cli containerd docker-buildx-plugin docker-compose-plugin

# Verify installation
sudo docker run hello-world

If everything is configured correctly, you'll see a "Hello from Docker!" message confirming the installation was successful.

Step 4: Configure Docker as a Non-Root User (Optional)

For security, it's best to run Docker as a non-root user. Here's how to add a user to the Docker group:

# Create a new user
sudo usermod -aG docker username

# Log out and log back in for changes to take effect
# Or use 'newgrp docker' to apply immediately

Replace username with your preferred username.

Step 5: Install Docker Compose

Docker Compose allows you to define and run multi-container applications. Install it with:

# Download the current stable release
sudo curl -L "https://github.com/docker/compose/releases/download/v2.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

# Make it executable
sudo chmod +x /usr/local/bin/docker-compose

# Verify installation
docker-compose --version

Step 6: Deploy Your First Container

Let's deploy a practical example - an NGINX web server container:

# Create a directory for your project
mkdir -p ~/my-webapp
cd ~/my-webapp

# Create a simple docker-compose.yml
cat > docker-compose.yml < html/index.html <

# View running containers
docker ps

# View all containers (including stopped)
docker ps -a

# Stop a container
docker stop container_name_or_id

# Start a container
docker start container_name_or_id

# View container logs
docker logs container_name_or_id

# Remove a container
docker rm container_name_or_id

sudo usermod -aG docker $USER

ports:
  - "8080:80"  # Map to port 8080 instead

# Remove unused containers, networks, and images
docker system prune -a

# Remove all unused data
docker system prune --volumes
