## What it is
Unregistry is a lightweight container image registry that stores and serves images directly from a Docker daemon's storage. Its `docker pussh` CLI plugin pushes Docker images straight to remote servers over SSH, transferring only missing layers without needing an external registry.

## Use cases
- push a docker image to a remote server without a registry
- deploy locally built images to production over ssh
- transfer only missing image layers to a server
- avoid paying for private docker registry storage
- replace docker save/load with faster image transfer
- self-host container images without exposing ports

## When to choose
- you need to move images between Docker hosts without setting up or paying for a registry
- you want fast transfers that skip layers already on the remote server
- you deploy to a few servers over SSH and want a simple rsync-like workflow
- you use Uncloud or a similar multi-host Docker setup

## When to avoid
- you need a persistent, shared registry for CI/CD pipelines or teams pulling images
- you target Kubernetes clusters rather than plain Docker hosts
- you need image vulnerability scanning, retention policies, or registry access controls
