UI APT Mirror

A containerized APT mirror solution with a web interface. This project provides a complete local Ubuntu / Debian package repository with an admin panel, file hosting capabilities, optional npm package caching, and developer cheatsheets. Perfect for organizations that need to work in a totally offline environment while maintaining access to essential development resources.

Features

• APT Mirror: Local Ubuntu package repository with automatic synchronization using apt-mirror2 (Python/asyncio version) from PyPI
• NPM Proxy: Optional local npm package registry cache for faster npm installs and reduced bandwidth usage
• Developer Cheatsheets: Built-in command reference with tldr-pages integration for offline access to programming and system administration guides
• Web Interface: web UI for all services
• Multi-Host Setup: Five distinct web services:
  • mirror.intra - DEB packages repository
  • admin.mirror.intra - Admin panel with authentication
  • files.mirror.intra - File hosting service
  • npm.mirror.intra - NPM registry cache (optional)
  • cheatsheets.mirror.intra - Public developer cheatsheets (no authentication)
• Advanced File Manager: File upload/download, directory management, built-in media player for video/audio files, and container image downloads from Docker Hub and GCR
• Multi-Architecture Support: Builds for both AMD64 and ARM64
• Easy Deployment: Simple scripts for building and deployment
• Configurable: Custom domains, sync frequency, admin passwords, and optional npm proxy

Requirements

• arm64 or amd64 machine
• Docker and Docker Compose
• Linux system
• Complete Mirroring apt repos usually requires a lot of disk space (> 500G)

Installation

1. Build the Images

First, build the Docker images for your architecture:

./build.sh

This will create:

• dist/ui-apt-mirror-amd64.tar.gz (for x86_64 systems)
• dist/ui-apt-mirror-arm64.tar.gz (for ARM64 systems)

2. Deploy the Container

Run the setup script to deploy the container:

./setup.sh

The script will:

• Detect your system architecture
• Ask for your custom domain (default: mirror.intra)
• Configure sync frequency
• Set admin password
• Ask if you need npm proxy functionality (default: Yes)
• Load the appropriate Docker image
• Start the container

NPM Proxy (npm.mirror.intra) - Optional

• URL: http://npm.mirror.intra

  • Caches npm packages locally for faster installs
  • Reduces bandwidth usage
  • Transparent proxy to npmjs.org
  • Private package publishing (requires authentication)
  • Private packages stored separately and never forwarded to npmjs.org

Usage

Using the APT Mirror

To use the local repository on your Ubuntu systems, add the following to /etc/apt/sources.list:

# Replace mirror.intra with your custom domain
# For Ubuntu 24.04 (Noble)
Types: deb
URIs: http://mirror.intra/archive.ubuntu.com/ubuntu
Suites: noble noble-updates noble-security noble-backports
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg

# For Debian 12 (Bookworm)
deb http://mirror.intra/deb.debian.org/debian bookworm main non-free-firmware
deb http://mirror.intra/security.debian.org/debian-security bookworm-security main non-free-firmware
deb http://mirror.intra/deb.debian.org/debian bookworm-updates main non-free-firmware

Then update your package lists:

sudo apt update

Managing the Mirror

Access the admin panel at http://admin.mirror.intra to:

• Monitor sync status
• View logs and statistics

Using the NPM Proxy

To use the local npm proxy (if enabled during setup), configure npm to use your local registry:

# Configure npm to use the local proxy
npm config set registry http://npm.mirror.intra

# Or for a specific project
npm install --registry http://npm.mirror.intra

# To revert back to the official registry
npm config set registry https://registry.npmjs.org

The npm proxy will:

• Cache packages locally on first download
• Serve cached packages for subsequent requests
• Automatically fetch from npmjs.org if not cached

Publishing NPM Packages

The npm proxy supports publishing private packages using standard npm commands.

Authentication

Method 1: Using npm login (recommended)

For npm 9.x+, use the --auth-type=legacy flag:

npm login --registry=http://npm.mirror.intra --auth-type=legacy
# Enter your username and password when prompted
npm whoami --registry=http://npm.mirror.intra

Method 2: Manual token configuration

If npm login doesn't work, you can manually obtain and configure the token:

TOKEN=$(curl -X PUT http://npm.mirror.intra/-/user/org.couchdb.user:admin \
  -H "Content-Type: application/json" \
  -d '{"name": "admin", "password": "your-password"}' \
  | jq -r .token)
echo "//npm.mirror.intra/:_authToken=$TOKEN" >> ~/.npmrc
npm whoami --registry=http://npm.mirror.intra

Publishing Packages

Once authenticated, publish packages normally:

npm publish

Important Notes:

• All published packages are treated as private packages
• Private packages are stored in data/data/npm/private/
• Public packages (cached from npmjs.org) are stored in data/data/npm/public/
• Published packages are NOT forwarded to npmjs.org
• Private packages take precedence over cached public packages
• Authentication tokens for npm are JWT-based and valid for 1 year

File Hosting

Use the file repository at http://files.mirror.intra to:

• Upload files via web interface
• Browse uploaded files

Management

Upgrading the Installation

To upgrade to the latest version:

./upgrade.sh

The upgrade script will:

• Check connectivity to the official website
• Ask you to choose between current architecture or all architectures
• Download the latest version
• Extract and install new image files
• Run setup.sh to deploy the upgrade
• Clean up temporary files
