DiunDash 🐳

A modern, dark-themed dashboard for visualizing and managing Diun (Docker Image Update Notifier) webhook data. Built with Rust and Actix-web for high performance and reliability.

Features

• 🎨 Modern Dark UI - Beautiful dark theme optimized for monitoring dashboards
• 📊 Grid View - Visual grid display of all container images with essential information
• 🔍 Hover Details - Detailed information appears on hover for each image
• ⚠️ Age Indicators - Color-coded cards based on image age:
  • Normal (within 1 week)
  • Yellow (over 1 week old)
  • Red (over 1 month old)
• 🗑️ Admin Panel - Delete images directly from the admin interface (/admin)
• 🔗 Quick Links - Click any image card to open its Docker Hub page
• 📅 Smart Dates - Relative time display (e.g., "2h ago", "3d ago")
• 🔄 Auto-refresh - Automatically updates every 30 seconds

Screenshots

The dashboard displays container images in a responsive grid layout with:

• Image name at the top
• Whale icon in the center
• Full image path
• Last updated timestamp
• Age-based color coding

Installation

Using Docker (Recommended)

# Build the image
docker build -t diundash .

# Run the container
docker run -d \
  -p 5030:5030 \
  -v $(pwd)/data:/app/data \
  --name diundash \
  diundash

From Source

# Clone the repository
git clone <repository-url>
cd DiunWeb

# Build the project
cargo build --release

# Run the application
./target/release/diundash

Configuration

Diun Webhook Setup

Configure Diun to send webhooks to DiunDash:

# diun.yml
notif:
  webhook:
    endpoint: http://your-server:5030/api/diun
    method: POST
    headers:
      Content-Type: application/json

Usage

Main Dashboard

• URL: http://localhost:5030/
• View all container images in a grid layout
• Click any card to open the Docker Hub page
• Hover over cards to see detailed information
• Fixed admin button (⚙️) in the bottom-right corner

Admin Panel

• URL: http://localhost:5030/admin
• Same view as main dashboard with delete functionality
• Click the ✕ button on any card to delete it from the database
• Confirmation dialog prevents accidental deletions

API Endpoints

• GET /api/webhooks - Get all container images
• POST /api/diun - Receive Diun webhook (used by Diun)
• DELETE /api/webhooks/{image} - Delete an image (admin only)

Data Storage

DiunDash uses SQLite to store webhook data. The database is located at:

• Local: ./data/diun.db
• Docker: /app/data/diun.db (mounted volume)

Development

Prerequisites

• Rust 1.75 or later
• Cargo

Building

cargo build --release

Running in Development

cargo run

Technology Stack
