Installing Docker Engine

Koios runs as a Docker container, so Docker Engine must be installed on the host machine. This page covers the essentials.

Docker Engine, Not Docker Desktop

Docker Desktop is not required. Docker Engine (the CLI-based runtime) is all you need for a server deployment.

Install Docker Engine

Follow the official Docker documentation to install Docker Engine on Ubuntu:

Refer to the official Docker Engine installation guide for Ubuntu for detailed, up-to-date instructions.

By default, Docker commands require sudo. To run Docker as your regular user:

sudo usermod -aG docker $USER

Log out and back in for the group change to take effect.

docker --version

docker run hello-world

If both commands succeed, Docker is ready.
