Running Docker Containers on a VPS: A Beginner’s Guide

+ Installing a VPN on Your VPS (OpenVPN or WireGuard)

Meta Description: Learn how to use your VPS to run Docker containers and host a secure VPN. This beginner’s guide covers key use cases, benefits, and how to get started — no deep sysadmin knowledge required.

Part 1: Running Docker Containers on a VPS – A Beginner’s Guide

What Is Docker?

Docker is a containerization tool that allows you to package your application and its dependencies into a single unit that runs reliably across any environment — including your VPS.

Think of it like shipping your app in a sealed box that works anywhere you put it.

Why Use Docker on a VPS?

Combining Docker with VPS hosting gives you the perfect environment for deploying modern apps. Here’s why developers and teams love it:

✅ Key Benefits:

• Isolation: Run multiple containers without them affecting each other

• Efficiency: Lightweight compared to traditional VMs

• Portability: Move containers across environments (dev → test → prod)

• Speed: Fast deployment and scaling

• Simplicity: Reuse Docker images and automate builds

Common Use Cases:

• Hosting microservices (APIs, front-end/back-end stacks)

• Running databases or dev tools (PostgreSQL, Redis, MongoDB)

• Deploying SaaS projects or test environments

• Setting up self-hosted platforms like Gitea, Ghost, or Nextcloud

️ What You’ll Need to Start:

• A VPS with at least 1 vCPU and 1GB RAM

• Ubuntu or Debian preferred for simplicity

• Root or sudo access

• Docker and Docker Compose installed (one-liners available)

Once Docker is installed, you can deploy full apps with just one command:

				
					docker-compose up -d

				
			

Bonus Tip: Use Portainer for Easy Management

Not a fan of the terminal? Use Portainer, a Docker UI that lets you manage containers visually. It’s free, browser-based, and beginner-friendly.

️ Part 2: Installing a VPN on Your VPS (OpenVPN or WireGuard)

Why Host Your Own VPN?

Using a self-hosted VPN gives you:

• Privacy: Encrypt your traffic on public Wi-Fi

• Security: Bypass ISP snooping and geo-blocking

• Control: Choose your own VPN protocol and server location

• Savings: Avoid monthly VPN subscriptions

With your own VPS and a tool like WireGuard or OpenVPN, setting up a VPN is easier and faster than ever.

OpenVPN vs. WireGuard: Quick Comparison

Recommendation: Go with WireGuard for performance and simplicity.

️ What You Can Do With Your VPN VPS:

• Browse anonymously from your devices

• Access geo-blocked content or services

• Connect securely to your home/office network

• Route traffic from other devices via encrypted tunnels

✅ Tools That Make Setup Easy:

• Algo VPN – Zero-config WireGuard/OpenVPN deployer

• PiVPN – A beginner-friendly installer for WireGuard/OpenVPN

• Streisand (archived) – Still used by advanced users for Tor, Shadowsocks, and more

Many tools include auto-firewall configuration, client installers, and QR codes for mobile setup.

Bonus Use Case: Combine Docker + VPN

Want to route Docker apps through a VPN (e.g., for geo-unblocking)? You can run a VPN container and connect other containers to it.

✅ Final Thoughts: VPS = Dev Toolkit + Privacy Hub

With just one VPS, you can:

• Run multiple Dockerized apps

• Host secure, fast VPN tunnels

• Test, scale, and control your digital infrastructure — your way

Whether you’re building your first project or just looking to protect your online activity, a VPS is a powerful and affordable solution.
