# Multi-Registry Pull Through Cache 🚀

![Python](https://img.shields.io/badge/Python-3.12+-blue?logo=python&logoColor=white)
![Docker](https://img.shields.io/badge/Docker-Ready-blue?logo=docker&logoColor=white)
![License](https://img.shields.io/badge/License-MIT-green)
![Traefik](https://img.shields.io/badge/Traefik-Proxy-orange?logo=traefikproxy&logoColor=white)
![Redis](https://img.shields.io/badge/Redis-Cache-red?logo=redis&logoColor=white)

Generate a complete Docker Compose stack with pull-through caches for multiple container registries, fronted by Traefik and accelerated by Redis.

> **⚠️ Migrating from v1.x scripts?**
>
> See the [upgrade guide](docs/upgrading.md). TL;DR: `python setup.py` → `multi-registry-cache setup`, `python generate.py` → `multi-registry-cache generate`. Your `config.yaml` and Docker usage are **fully compatible**.

## 🚀 Features

| Feature | Description |
| --- | --- |
| 🏗️ **Multi-Registry** | Mirror Docker Hub, GHCR, Quay, NVCR, or any OCI registry |
| 🔒 **Private Registry** | Add a standalone private registry alongside your caches |
| 🌐 **Traefik Proxy** | Automatic TLS termination and subdomain-based routing |
| ⚡ **Redis Acceleration** | Blob descriptor caching for faster repeated pulls |
| 🧙 **Interactive Wizard** | Guided `setup` command to generate your `config.yaml` |
| 📦 **Installable CLI** | `uvx`, `pipx`, `pip install`, or Docker — your choice |
| ☸️ **K8s Ready** | Works with k3s, RKE2, containerd, dockerd |
| 🗄️ **Flexible Storage** | Filesystem, S3, GCS, or in-memory backends |
| 🔧 **Customizable** | Full control over Traefik, registry, and Compose config via `{name}` interpolation |
| 🌱 **Eco-Friendly** | Less external bandwidth = smaller carbon footprint |

---

## 📦 Installation

| Method | Command |
| --- | --- |
| **uvx** (zero install) | `uvx multi-registry-cache setup` |
| **uv tool** | `uv tool install multi-registry-cache` |
| **pipx** | `pipx install multi-registry-cache` |
| **pip** | `pip install multi-registry-cache` |
| **Docker** | See below |

```bash
# Docker — interactive setup
docker run --rm -ti -v "./config.yaml:/app/config.yaml" obeoneorg/multi-registry-cache setup

# Docker — generate compose/ from an existing config.yaml
docker run --rm -v "./config.yaml:/app/config.yaml" -v "./compose:/app/compose" obeoneorg/multi-registry-cache generate
```

---

## 🛠️ Quick Start

```mermaid
flowchart LR
    A["1️⃣ setup"] --> B["2️⃣ edit config"] --> C["3️⃣ generate"] --> D["4️⃣ docker compose up"]
```

```bash
# 1. Create config interactively
multi-registry-cache setup

# 2. Fine-tune config.yaml (TLS, storage, hostnames…)
# See docs/configuration.md

# 3. Generate the stack
multi-registry-cache generate

# 4. Start
cd compose && docker compose up -d
```

---

## ⚙️ CLI Reference

| Command | Description |
| --- | --- |
| `multi-registry-cache setup [--config PATH]` | Interactive wizard → `config.yaml` |
| `multi-registry-cache generate [--config PATH] [--output-dir DIR]` | Read config → generate `compose/` |
| `multi-registry-cache completion [zsh\|bash\|fish]` | Print shell completion script |
| `multi-registry-cache --help` | Show all commands |

## 🔄 Configuring Container Runtimes

Point your container runtime at the cache after deploying the stack. Quick examples below — see [docs/runtime-configuration.md](docs/runtime-configuration.md) for full instructions (nerdctl, RKE2, BuildKit, Docker Desktop…).

### containerd

```toml
# /etc/containerd/config.toml
[plugins."io.containerd.grpc.v1.cri".registry.mirrors]
  [plugins."io.containerd.grpc.v1.cri".registry.mirrors."docker.io"]
    endpoint = ["https://dockerhub.registry-cache.example.net"]
  [plugins."io.containerd.grpc.v1.cri".registry.mirrors."ghcr.io"]
    endpoint = ["https://ghcr.registry-cache.example.net"]
```

```bash
sudo systemctl restart containerd
```

### dockerd

```json
{ "registry-mirrors": ["https://dockerhub.registry-cache.example.net"] }
```

```bash
sudo systemctl daemon-reload && sudo systemctl restart docker
```

### k3s / RKE2

```yaml
# /etc/rancher/k3s/registries.yaml
mirrors:
  docker.io:
    endpoint: ["https://dockerhub.registry-cache.example.net"]
  ghcr.io:
    endpoint: ["https://ghcr.registry-cache.example.net"]
```
