¿Qué es unregistry?
unregistry is a lightweight container image registry created by Pasha Sviderski that stores and serves images directly from your Docker daemon's storage. The included docker pussh command lets you push images straight to remote Docker servers over SSH, transferring only missing layers for maximum efficiency.
- Docker Hub/GHCR: Your code becomes public or you pay for private repos
- Self-hosted registry: Another service to maintain, secure, and pay for
- Save/Load: Transfers entire image even if 90% already exists on server
- Remote rebuild: Wastes time and server resources, debugging production builds
docker pussh myapp:latest user@server - That's it! Your image is on the remote server with no registry setup, no subscription, no intermediate storage, just direct transfer of missing layers over SSH.
⚡ Key Features of unregistry
🚀 Direct Transfer
Push images directly to remote servers over SSH. No intermediate registry, no exposed ports, just efficient point-to-point transfer.
📦 Layer Deduplication
Transfers only missing layers, like rsync for Docker images. If 90% of your image exists remotely, only 10% gets transferred.
🔒 Secure by Design
Uses SSH for authentication and transport. No exposed registry ports, no additional security configuration needed.
⚡ Zero Setup
No registry infrastructure to maintain. Works with any server that has Docker and SSH access.
🏗️ CI/CD Ready
Perfect for deployment pipelines. Build locally or in CI, push directly to production servers without registry complexity.
🌐 Multi-Platform
Supports multi-platform images with containerd image store. Deploy ARM and x86 images efficiently.
apt upgrade te mantiene siempre en la última versión.
📦 Instalación desde deb.griffo.io
Paso 1: Agregar repositorio
sudo install -d -m 0755 /etc/apt/keyrings
curl -fsSL https://deb.griffo.io/EA0F721D231FDD3A0A17B9AC7808B4DD62C41256.asc | sudo gpg --dearmor --yes -o /etc/apt/keyrings/deb.griffo.io.gpg
echo "deb [signed-by=/etc/apt/keyrings/deb.griffo.io.gpg] https://deb.griffo.io/apt $(lsb_release -sc 2>/dev/null) main" | sudo tee /etc/apt/sources.list.d/deb.griffo.io.list > /dev/null
sudo apt updateinstall -d -m 0755 /etc/apt/keyrings
curl -fsSL https://deb.griffo.io/EA0F721D231FDD3A0A17B9AC7808B4DD62C41256.asc | gpg --dearmor --yes -o /etc/apt/keyrings/deb.griffo.io.gpg

sudo apt update🆓 Existe un espejo gratis para siempre. deb-free.griffo.io sirve paquetes gratis para siempre: sin cuenta, sin suscripción, como máximo 2 meses por detrás del upstream, correcciones de seguridad inmediatas. Ahora mismo incluye cliamp, Ghostty, lazydocker, Oh My Posh y Zed; Unregistry no está entre ellas, así que hoy el repositorio de arriba es la única forma de instalarlo — pídelo y puede añadirse.
🧩 Sobre la opción extrepo. extrepo es la herramienta propia de Debian para repositorios externos: escribe el archivo de sources e instala la clave de firma por ti, comprobándola antes contra metadatos firmados. Este repositorio está registrado en ella como griffo, y el espejo gratuito para siempre como griffo-free, así que en Debian (bookworm, trixie, forky y sid) los comandos de arriba son toda la configuración.
extrepo solo configura el archivo de sources y la clave: las credenciales de una suscripción siguen yendo en /etc/apt/auth.conf.d/deb.griffo.io.conf. Ubuntu no está cubierto, porque extrepo publica metadatos solo para las suites de Debian: allí usa los comandos con sudo o como root.

apt install unregistry docker-pussh
# Verificar instalación
docker pussh --version🎯 Ejemplos de uso básico
Simple image push:
# Build image locally
docker build -t myapp:latest .
# Push directly to remote server
docker pussh myapp:latest user@server.example.com
# That's it! Image is now available on remote serverAdvanced usage:
# Push with SSH key
docker pussh myapp:latest ubuntu@192.168.1.100 -i ~/.ssh/id_rsa
# Custom SSH port
docker pussh myapp:latest user@server:2222
# Specific platform for multi-arch images
docker pussh myapp:latest user@server --platform linux/amd64
# Use in deployment script
docker pussh myapp:$VERSION deploy@prod-server
ssh deploy@prod-server docker run -d myapp:$VERSIONCI/CD integration:
# GitHub Actions example
- name: Build and deploy
run: |
docker build -t myapp:${{ github.sha }} .
