How to Run Docker on a Fresh VPS

Docker turns a bare VPS into a place to run almost any app in a container. Here's the quickest way to install it on a fresh server and launch your first container.

Deploy the server

Create a VPS with Ubuntu (a 1 GB box is fine to start; use 2 GB+ if you'll run several containers). You'll have a root shell in about 60 seconds. Some providers, Kvantis included, also offer a one-click Docker image so it's preinstalled.

Install Docker

If it's not preinstalled:

apt update
apt install -y docker.io
systemctl enable --now docker

Check it works:

docker run hello-world

Run a real container

For example, an nginx web server on port 80:

docker run -d --name web -p 80:80 nginx

Visit your server's IP in a browser and you'll see the nginx page.

Keep containers running

Add --restart unless-stopped so containers survive reboots:

docker run -d --restart unless-stopped -p 80:80 nginx

For multi-container apps, install Docker Compose and describe everything in one file.

Why a VPS for Docker?

• Always-on — unlike your laptop.
• Isolated — containers keep apps tidy and reproducible.
• Cheap and disposable — hourly billing means you can tear it all down anytime.
