+# Planning Guide
+
+A secure container management dashboard that displays active containers and enables administrators to launch interactive shell sessions with credential-based authentication.
+
+**Experience Qualities**:
+1. **Authoritative** - Professional security-focused interface that conveys control and system oversight
+2. **Efficient** - Streamlined workflows with minimal clicks from viewing containers to accessing shells
+3. **Technical** - Terminal-inspired aesthetics that resonate with developer and operations audiences
+
+**Complexity Level**: Light Application (multiple features with basic state)
+This is a focused management tool with authentication, container listing, and shell interaction—multiple coordinated features but not extensive state management beyond session auth.
+
+## Essential Features
+
+### Authentication Gate
+- **Functionality**: Username and password validation against configured credentials
+- **Purpose**: Protect container access from unauthorized users
+- **Trigger**: User loads the application without valid session
+- **Progression**: Login form display → Credential input → Validation → Dashboard access or error feedback
+- **Success criteria**: Valid credentials grant access; invalid credentials show clear error; session persists across page refreshes
+
+### Container List View
+- **Functionality**: Display all active containers with key metadata (name, image, status, uptime)
+- **Purpose**: Provide visibility into running container infrastructure
+- **Trigger**: Successful authentication or app load with valid session
+- **Progression**: Dashboard load → Fetch container data → Render container cards → Auto-refresh every 10 seconds
+- **Success criteria**: All active containers visible with accurate real-time data; clear empty state when no containers exist
+
+### Interactive Shell Access
+- **Functionality**: Launch terminal session within selected container
+- **Purpose**: Enable debugging, inspection, and administration tasks
+- **Trigger**: User clicks "Open Shell" action on a container card
+- **Progression**: Container selection → Shell modal opens → Terminal initializes → User interacts with container shell → Close to return to dashboard
+- **Success criteria**: Terminal displays container shell prompt; commands execute and return output; session closes cleanly
+
+### Session Management
+- **Functionality**: Logout capability and session timeout handling
+- **Purpose**: Security and access control
+- **Trigger**: User clicks logout or session expires
+- **Progression**: Logout action → Clear session → Return to login screen
+- **Success criteria**: User can explicitly log out; returns to login without residual access
+
+## Edge Case Handling
+- **No Active Containers**: Display friendly empty state with icon and helpful message
+- **Authentication Failure**: Clear error messaging without exposing security details
+- **Container Stops Mid-Session**: Terminal shows disconnection message, returns user to dashboard
+- **Network Interruption**: Loading states and retry mechanisms for data fetching
+- **Malformed Credentials**: Input validation and sanitization before submission
+
+## Design Direction
+The design should evoke precision, technical competence, and security. Think command-line interfaces elevated to GUI form—monospace typography, high contrast, structured layouts with clear information hierarchy. The aesthetic should feel like a professional operations dashboard: serious, focused, and trustworthy.
+
+## Color Selection
+
+A dark, terminal-inspired palette with high-contrast accents for critical actions and status indicators.
+
+- **Primary Color**: Deep slate blue `oklch(0.25 0.02 250)` - Commands authority and technical sophistication, used for primary actions
+- **Secondary Colors**: 
+  - Dark charcoal background `oklch(0.15 0.01 250)` - Reduces eye strain for prolonged monitoring
+  - Slate gray surfaces `oklch(0.22 0.015 250)` - Cards and elevated elements
+- **Accent Color**: Electric cyan `oklch(0.75 0.15 195)` - High-visibility accent for interactive elements and status indicators
+- **Foreground/Background Pairings**:
+  - Background (Dark Charcoal `oklch(0.15 0.01 250)`): Light cyan text `oklch(0.92 0.02 195)` - Ratio 7.2:1 ✓
+  - Primary (Deep Slate `oklch(0.25 0.02 250)`): White text `oklch(0.98 0 0)` - Ratio 8.5:1 ✓
+  - Accent (Electric Cyan `oklch(0.75 0.15 195)`): Dark text `oklch(0.15 0.01 250)` - Ratio 6.1:1 ✓
+  - Card (Slate Gray `oklch(0.22 0.015 250)`): Light cyan text `oklch(0.92 0.02 195)` - Ratio 6.8:1 ✓
+
+## Font Selection
+Typography should evoke terminal interfaces while maintaining excellent readability—monospace for technical data and code, geometric sans-serif for UI labels.
+
+- **Typographic Hierarchy**:
+  - H1 (Page Title): JetBrains Mono Bold/32px/tight tracking (-0.02em)
+  - H2 (Section Headers): Space Grotesk SemiBold/24px/normal tracking
+  - H3 (Container Names): JetBrains Mono Medium/18px/normal tracking
+  - Body (Metadata): Space Grotesk Regular/14px/relaxed leading (1.6)
+  - Code/Terminal: JetBrains Mono Regular/14px/normal leading (1.5)
+  - Labels: Space Grotesk Medium/12px/wide tracking (0.02em)
+
+## Animations
+Animations should be crisp and purposeful, reinforcing the technical, responsive nature of the interface.
+
+- Terminal modal: Scale up from 0.95 with fade, 250ms ease-out
+- Container cards: Subtle hover lift (2px translate-y) with 150ms ease
+- Status indicators: Pulse animation for active/running state
+- Login form: Shake animation on authentication error
+- Data refresh: Subtle opacity pulse on container list update
+- Button interactions: Quick scale (0.98) on press, 100ms
+
+## Component Selection
+
+- **Components**:
+  - `Card` - Container display with metadata, modified with border-l accent for status
+  - `Button` - Primary actions (login, open shell, logout) with variant customization
+  - `Input` - Credential fields with secure password masking
+  - `Dialog` - Full-screen terminal modal overlay
+  - `Badge` - Status indicators (running, healthy, error states)
+  - `Separator` - Visual dividers between container metadata sections
+  - `ScrollArea` - Container list and terminal output scrolling
+  - `Alert` - Error messages and system notifications
+
+- **Customizations**:
+  - Terminal component: Custom component using monospace font and scrollable output area
+  - Container card: Custom status indicator with colored left border
+  - Auth layout: Custom centered card with gradient background overlay
+
+- **States**:
+  - Buttons: Default slate, hover electric cyan glow, active pressed, disabled muted
+  - Inputs: Default with subtle border, focus with cyan ring, error with red border
+  - Cards: Default elevation-1, hover elevation-2 with cyan accent glow
+  - Terminal: Active (connected) vs disconnected states with visual feedback
+
+- **Icon Selection**:
+  - Container: `Package` - represents containerized applications
+  - Shell/Terminal: `Terminal` - universal terminal symbol
+  - Status running: `Play` - active operation
+  - Status stopped: `Pause` or `Stop` - inactive state
+  - Login: `LockKey` - security and authentication
+  - Logout: `SignOut` - session termination
+  - Refresh: `ArrowClockwise` - data reload
+  - Error: `Warning` - alert states
+
+- **Spacing**:
+  - Page padding: p-6 (desktop), p-4 (mobile)
+  - Card padding: p-6
+  - Card gaps: gap-4
+  - Section spacing: space-y-6
+  - Button padding: px-6 py-3
+  - Form field spacing: space-y-4
+  - Container grid gap: gap-4
+
+- **Mobile**:
+  - Container grid: 1 column on mobile, 2 on tablet (768px+), 3 on desktop (1024px+)
+  - Terminal modal: Full screen on mobile with close button in header
+  - Header: Stack logo and logout button vertically on small screens
+  - Auth form: Full width on mobile (max-w-sm) with reduced padding
+  - Metadata: Stack container info vertically on mobile, horizontal on desktop

+- Username: `admin`
+- Password: `admin123`
+
+### Manual Setup
+
+#### Backend Setup
+
+1. Navigate to the backend directory:
+```bash
+cd backend
+```
+
+2. Install Python dependencies:
+```bash
+pip install -r requirements.txt
+```
+
+3. Create `.env` file (optional):
+```bash
+cp .env.example .env
+# Edit .env to set custom credentials
+```
+
+4. Run the Flask application:
+```bash
+python app.py
+```
+
+The backend will be available at http://localhost:5000
+
+#### Frontend Setup
+
+1. Navigate to the frontend directory:
+```bash
+cd frontend
+```
+
+2. Install Node.js dependencies:
+```bash
+npm install
+```
+
+3. Create `.env.local` file:
+```bash
+cp .env.local.example .env.local
+# Edit if backend is running on a different URL
+```
+
+4. Run the development server:
+```bash
+npm run dev
+```
+
+The frontend will be available at http://localhost:3000
+
+## Configuration
+
+### Backend Environment Variables
+
+- `ADMIN_USERNAME` - Admin username (default: `admin`)
+- `ADMIN_PASSWORD` - Admin password (default: `admin123`)
+- `FLASK_ENV` - Flask environment (default: `development`)

+- `GET /api/health` - Health check endpoint
+
+## Docker Images
+
+Images are automatically built and pushed to GitHub Container Registry on every push to main:
+
+- Backend: `ghcr.io/johndoe6345789/docker-swarm-termina-backend`
+- Frontend: `ghcr.io/johndoe6345789/docker-swarm-termina-frontend`
+
+## Security Considerations
+
+⚠️ **Important Security Notes:**
+
+1. **Change Default Credentials** - Always change the default admin credentials in production
+2. **Docker Socket Access** - The backend requires access to Docker socket (`/var/run/docker.sock`)
+3. **Network Security** - Use proper firewall rules and network isolation
+4. **HTTPS** - Use HTTPS in production (reverse proxy recommended)
+5. **Session Management** - Current implementation uses simple token-based auth; consider implementing JWT or OAuth for production

+# Backend - Flask API
+
+Python Flask backend for Docker container management.
+
+## Features
+
+- RESTful API for container management
+- Docker SDK integration
+- Session-based authentication
+- CORS enabled for frontend access
+
+## Setup
+
+1. Install dependencies:
+```bash
+pip install -r requirements.txt
+```
+
+2. Configure environment (optional):
+```bash
+cp .env.example .env
+# Edit .env with your settings
+```
+
+3. Run the server:
+```bash
+python app.py
+```
+
+The server will start on http://localhost:5000
+
+## API Endpoints
+
+### Authentication
+- `POST /api/auth/login` - Login with username/password
+- `POST /api/auth/logout` - Logout current session
+
+### Containers
+- `GET /api/containers` - List all containers (requires auth)
+- `POST /api/containers/<id>/exec` - Execute command in container (requires auth)
+
+### Health
+- `GET /api/health` - Health check
+
+## Docker
+
+Build the Docker image:
+```bash
+docker build -t docker-swarm-backend .
+```
+
+Run the container:
+```bash
+docker run -p 5000:5000 -v /var/run/docker.sock:/var/run/docker.sock docker-swarm-backend
+```
+
+## Security
+
+⚠️ This backend requires access to the Docker socket. Ensure proper security measures are in place in production environments.

+This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
+
+## Getting Started
+
+First, run the development server:
+
+```bash
+npm run dev
+# or
+yarn dev
+# or
+pnpm dev
+# or
+bun dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+
+You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+
+This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
+
+## Learn More
+
+To learn more about Next.js, take a look at the following resources:
+
+- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+
+You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
+
+## Deploy on Vercel
+
+The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
+
+Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.
