mirava

Universal proxy for Docker registry and PyPI mirrors with automatic failover.

Features

• Docker Registry Proxy: Transparent mirror for Docker Hub with fallback
• PyPI Proxy: Python package index mirror with automatic retry
• Health Monitoring: Automatic mirror health checks and degradation
• Dynamic Configuration: Add/remove mirrors via API
• Swagger UI: Built-in API documentation

Installation

git clone https://github.com/yourusername/mirava.git
cd mirava
uv sync

Quick Start

# Run with default configuration
uv run mirava

# Or run directly
uv run python -m mirava.main

Server starts on http://localhost:8080

Configuration

Environment Variables

Variable	Default	Description
HOST	0.0.0.0	Server bind address
PORT	8080	Server port
PYPI_OFFICIAL_URL	https://pypi.org/simple	Official PyPI index
PYPI_MIRRORS	(built-in)	Comma-separated PyPI mirrors
DOCKER_OFFICIAL_URL	https://registry-1.docker.io	Official Docker registry
DOCKER_MIRRORS	(built-in)	Comma-separated Docker mirrors

Examples

# Use custom PyPI index
PYPI_OFFICIAL_URL=https://pypi.company.internal/simple uv run mirava

# Custom mirrors only
PYPI_MIRRORS="https://mirror1.com/simple,https://mirror2.com/simple" \
DOCKER_MIRRORS="https://docker-mirror1.com,https://docker-mirror2.com" \
uv run mirava

Docker Setup

Configure Docker to use the proxy:

sudo tee /etc/docker/daemon.json <<EOF
{
  "registry-mirrors": ["http://127.0.0.1:8080"],
  "insecure-registries": ["127.0.0.1:8080"]
}
EOF
sudo systemctl restart docker

Now use Docker normally:

docker pull hello-world
docker pull nginx

PyPI Setup

Configure pip to use the proxy:

# Global config
pip config set global.index-url http://127.0.0.1:8080/simple
pip config set global.trusted-host 127.0.0.1

# Or per-command
pip install --index-url http://127.0.0.1:8080/simple --trusted-host 127.0.0.1 requests

Or use environment variables:

export PIP_INDEX_URL=http://127.0.0.1:8080/simple
export PIP_TRUSTED_HOST=127.0.0.1
pip install requests

Adding New Mirror Types

1. Create new file src/mirava/npm.py:

from fastapi import APIRouter
from .mirrors import registry

router = APIRouter(tags=["NPM"])

@router.get("/npm/{package}")
async def npm_proxy(package: str):
    # Implementation
    pass

2. Add mirrors to mirrors.py:

NPM_MIRRORS = [
    ("https://registry.npmmirror.com", "npmmirror", 0),
]

3. Register in init_mirrors():

npm_mgr = BaseMirrorManager("npm")
npm_mgr.official_url = "https://registry.npmjs.org"
for url, name, priority in NPM_MIRRORS:
    npm_mgr.add_mirror(url, name, priority)
registry.register("npm", npm_mgr)

4. Include router in main.py:

from . import npm
app.include_router(npm.router)

Development

# Run in development mode with auto-reload
uv run --reload mirava

# Or with Python directly
cd src
PYTHONPATH=. uvicorn mirava.main:create_app --factory --reload
