But it's not possible to have a running container without **at least one running process**. If the main process stops, the container stops.

## Build a Docker Image for FastAPI

Okay, let's build something now! 🚀

I'll show you how to build a **Docker image** for FastAPI **from scratch**, based on the **official Python** image.

This is what you would want to do in **most cases**, for example:

		errs = append(errs, err)
	}

	// Annotate the node with the crisocket information, sourced either from the InitConfiguration struct or
	// --cri-socket.
	// TODO: In the future we want to use something more official like NodeStatus or similar for detecting this properly
	if err := patchnodephase.AnnotateCRISocket(client, cfg.NodeRegistration.Name, cfg.NodeRegistration.CRISocket); err != nil {
