Gitea Mirror

Automatically mirror repositories from GitHub to your self-hosted Gitea instance.

> [!IMPORTANT] > **Upgrading to v3?** v3 requires a fresh start with a new data volume. Please read the [Upgrade Guide](UPGRADE.md) for instructions. ## 🚀 Quick Start ```bash # Fastest way - using the simplified Docker setup docker compose -f docker-compose.alt.yml up -d # Access at http://localhost:4321 ``` First user signup becomes admin. Configure GitHub and Gitea through the web interface!

Dashboard Dashboard Mobile

## ✨ Features - 🔁 Mirror public, private, and starred GitHub repos to Gitea - 🏢 Mirror entire organizations with flexible strategies - 🎯 Custom destination control for repos and organizations - 🔐 Secure authentication with Better Auth (email/password, SSO, OIDC) - 📊 Real-time dashboard with activity logs - ⏱️ Scheduled automatic mirroring - 🐳 Dockerized with multi-arch support (AMD64/ARM64) ## 📸 Screenshots

## Installation ### Docker (Recommended) We provide two Docker Compose options: #### Option 1: Quick Start (docker-compose.alt.yml) Perfect for trying out Gitea Mirror or simple deployments: ```bash # Clone repository git clone https://github.com/RayLabsHQ/gitea-mirror.git cd gitea-mirror # Start with simplified setup docker compose -f docker-compose.alt.yml up -d # Access at http://localhost:4321 ``` **Features:** - ✅ Pre-built image - no building required - ✅ Minimal configuration needed - ✅ Data stored in `./data` directory - ✅ Configure everything through web UI - ✅ Automatic user/group ID mapping **Best for:** - First-time users - Testing and evaluation - Simple deployments - When you prefer web-based configuration #### Option 2: Full Setup (docker-compose.yml) For production deployments with environment-based configuration: ```bash # Start with full configuration options docker compose up -d ``` **Features:** - ✅ Build from source or use pre-built image - ✅ Complete environment variable configuration - ✅ Support for custom CA certificates - ✅ Advanced mirror settings (forks, wiki, issues) - ✅ Multi-registry support **Best for:** - Production deployments - Automated/scripted setups - Advanced mirror configurations - When using self-signed certificates #### Using Pre-built Image Directly ```bash docker pull ghcr.io/raylabshq/gitea-mirror:v3.0.0 ``` ### Configuration Options #### Quick Start Configuration (docker-compose.alt.yml) Minimal `.env` file (optional - has sensible defaults): ```bash # Custom port (default: 4321) PORT=4321 # User/Group IDs for file permissions (default: 1000) PUID=1000 PGID=1000 # JWT secret (auto-generated if not set) JWT_SECRET=your-secret-key-change-this-in-production ``` All other settings are configured through the web interface after starting. #### Full Setup Configuration (docker-compose.yml) Supports extensive environment variables for automated deployment. See the full [docker-compose.yml](docker-compose.yml) for all available options including GitHub tokens, Gitea URLs, mirror settings, and more. ### LXC Container (Proxmox) ```bash # One-line install on Proxmox VE bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/gitea-mirror.sh)" ``` See the [Proxmox VE Community Scripts](https://community-scripts.github.io/ProxmoxVE/scripts?id=gitea-mirror) for more details. ### Manual Installation ```bash # Install Bun curl -fsSL https://bun.sh/install | bash # Setup and run bun run setup bun run dev ``` ## Usage 1. **First Time Setup** - Navigate to http://localhost:4321 - Create admin account (first user signup) - Configure GitHub and Gitea connections 2. **Mirror Strategies** - **Preserve Structure**: Maintains GitHub organization structure - **Single Organization**: All repos go to one Gitea organization - **Flat User**: All repos under your Gitea user account - **Mixed Mode**: Personal repos in one org, organization repos preserve structure 3. **Customization** - Click edit buttons on organization cards to set custom destinations - Override individual repository destinations in the table view - Starred repositories automatically go to a dedicated organization ## Troubleshooting ### Reverse Proxy Configuration If using a reverse proxy (e.g., nginx proxy manager) and experiencing issues with JavaScript files not loading properly, try enabling HTTP/2 support in your proxy configuration. While not required by the application, some proxy configurations may have better compatibility with HTTP/2 enabled. See [issue #43](https://github.com/RayLabsHQ/gitea-mirror/issues/43) for reference. ## Development ```bash # Install dependencies bun install # Run development server bun run dev # Run tests bun test # Build for production bun run build ``` ## Technologies - **Frontend**: Astro, React, Shadcn UI, Tailwind CSS v4 - **Backend**: Bun runtime, SQLite, Drizzle ORM - **APIs**: GitHub (Octokit), Gitea REST API - **Auth**: JWT tokens with bcryptjs password hashing ## Security ### Token Encryption - All GitHub and Gitea API tokens are encrypted at rest using AES-256-GCM - Encryption is automatic and transparent to users - Set `ENCRYPTION_SECRET` environment variable for production deployments - Falls back to `BETTER_AUTH_SECRET` or `JWT_SECRET` if not set ### Password Security - User passwords are hashed using bcrypt (via Better Auth) - Never stored in plaintext - Secure session management with JWT tokens ### Upgrading to v3 **Important**: If upgrading from v2.x to v3.0, please read the [Migration Guide](MIGRATION_GUIDE.md) for breaking changes and upgrade instructions. For quick token encryption migration: ```bash bun run migrate:encrypt-tokens ``` ## Authentication Gitea Mirror supports multiple authentication methods. **Email/password authentication is the default and always enabled.** ### 1. Email & Password (Default) The standard authentication method. First user to sign up becomes the admin. ### 2. Single Sign-On (SSO) with OIDC Enable users to sign in with external identity providers like Google, Azure AD, Okta, Authentik, or any OIDC-compliant service. **Configuration:** 1. Navigate to Settings → Authentication & SSO 2. Click "Add Provider" 3. Enter your OIDC provider details: - Issuer URL (e.g., `https://accounts.google.com`) - Client ID and Secret from your provider - Use the "Discover" button to auto-fill endpoints **Redirect URL for your provider:** ``` https://your-domain.com/api/auth/sso/callback/{provider-id} ``` ### 3. Header Authentication (Reverse Proxy) Perfect for automatic authentication when using reverse proxies like Authentik, Authelia, or Traefik Forward Auth. **Environment Variables:** ```bash # Enable header authentication HEADER_AUTH_ENABLED=true # Header names (customize based on your proxy) HEADER_AUTH_USER_HEADER=X-Authentik-Username HEADER_AUTH_EMAIL_HEADER=X-Authentik-Email HEADER_AUTH_NAME_HEADER=X-Authentik-Name # Auto-provision new users HEADER_AUTH_AUTO_PROVISION=true # Restrict to specific email domains (optional) HEADER_AUTH_ALLOWED_DOMAINS=example.com,company.org ``` **How it works:** - Users authenticated by your reverse proxy are automatically logged in - No additional login step required - New users can be auto-provisioned if enabled - Falls back to regular authentication if headers are missing **Example Authentik Configuration:** ```nginx # In your reverse proxy configuration proxy_set_header X-Authentik-Username $authentik_username; proxy_set_header X-Authentik-Email $authentik_email; proxy_set_header X-Authentik-Name $authentik_name; ``` ### 4. OAuth Applications (Act as Identity Provider) Gitea Mirror can also act as an OIDC provider for other applications. Register OAuth applications in Settings → Authentication & SSO → OAuth Applications tab. **Use cases:** - Allow other services to authenticate using Gitea Mirror accounts - Create service-to-service authentication - Build integrations with your Gitea Mirror instance ## Contributing Contributions are welcome!
