DigiServer Player SSH Deployment - Implementation Complete ✅

Overview

Successfully enhanced the DigiServer player creation workflow to support automated SSH-based deployment of player code to remote hosts running the Kiwy-Signage application.

🎯 What Was Built

1. SSH Deployment Utilities Module

File: digiserver-v2/app/utils/ssh_deploy.py

  • test_ssh_connection() - Non-interactive SSH connection tester

    • Uses sshpass for credential handling
    • Returns detailed connection status and errors
    • Timeout: 10 seconds

  • deploy_player_to_host() - Full automated deployment pipeline

    • Verifies SSH access
    • Creates deployment directory
    • Clones/updates Kiwy-Signage repository from: https://gitea.moto-adv.com/ske087/Kiwy-Signage.git
    • Executes installation scripts automatically
    • Returns step-by-step deployment status
    • Default deploy path: /opt/kiwy-signage

2. REST API Endpoints

File: digiserver-v2/app/blueprints/api.py

POST /api/deploy/test-ssh

Test SSH connectivity before deployment

Request: {
  "hostname": "192.168.1.100",
  "username": "pi",
  "password": "raspberry",
  "port": 22
}

Response: {
  "success": true/false,
  "message": "SSH connection successful/failed",
  "timestamp": "2026-06-07T19:00:00",
  "output": "SSH connection successful"
}

POST /api/deploy/player

Deploy player code to remote host

Request: {
  "hostname": "192.168.1.100",
  "username": "pi",
  "password": "raspberry",
  "player_name": "Office Display 1",
  "port": 22,
  "deploy_path": "/opt/kiwy-signage",
  "repo_url": "https://gitea.moto-adv.com/ske087/Kiwy-Signage.git"
}

Response: {
  "success": true/false,
  "message": "Player code deployed successfully",
  "timestamp": "2026-06-07T19:00:00",
  "deploy_path": "/opt/kiwy-signage",
  "steps": [
    {
      "step": "SSH Connection Test",
      "status": "completed",
      "message": "SSH connection successful",
      "timestamp": "..."
    },
    {
      "step": "Create Deploy Directory",
      "status": "completed",
      "message": "Directory /opt/kiwy-signage created",
      "timestamp": "..."
    },
    {
      "step": "Clone/Update Repository",
      "status": "completed",
      "message": "Pull latest code: Already up to date",
      "timestamp": "..."
    },
    {
      "step": "Run Installation Script",
      "status": "completed",
      "message": "Installation script executed: install.sh",
      "timestamp": "..."
    }
  ]
}

3. Enhanced Add Player Page

File: digiserver-v2/app/templates/players/add_player.html

Stage 1: SSH Connection Testing

  • Input fields for target hostname/IP, SSH port, username, password
  • Live connection test button with loading spinner
  • Color-coded status messages (green=success, red=error)
  • Clear/retry option if connection fails

Stage 2: Player Configuration

  • Appears only after SSH test succeeds
  • All existing player creation fields:
    • Display name
    • Hostname (player identifier)
    • Location
    • Password (optional)
    • Quick Connect Code
    • Orientation (Landscape/Portrait)
    • Playlist assignment
  • SSH credentials stored in hidden form fields
  • "Create & Deploy Player" button

UI Features

  • Fully responsive (mobile-friendly)
  • Dark mode support
  • Loading spinners during operations
  • Detailed help text
  • Information boxes with setup instructions

4. Updated Players Blueprint

File: digiserver-v2/app/blueprints/players.py

Modified add_player() route to:

  • Accept SSH credentials from enhanced form
  • Create player record in database
  • NEW: Trigger deployment after player creation
  • Display deployment status in success message
  • Show Auth Code in formatted code block
  • Log all operations including deployment results
  • Handle deployment failures gracefully

5. Docker Configuration

File: digiserver-v2/Dockerfile

Added deployment dependencies:

RUN apt-get update && \
    apt-get install -y --no-install-recommends \
    sshpass           # For non-interactive SSH
    git               # For cloning repositories
    openssh-client    # SSH client tools

🚀 User Workflow

How to Deploy a Player

  1. Navigate to Add Player Page

    • URL: http://localhost/digiserver/players/add

  2. Enter SSH Connection Details

    • Target hostname/IP address (192.168.1.100)
    • SSH port (default 22)
    • SSH username (e.g., pi, ubuntu)
    • SSH password

  3. Test SSH Connection

    • Click "Test SSH Connection" button
    • See live feedback (success or specific error)
    • SSH form fields lock after successful test

  4. Configure Player

    • Fill in player details:
      • Display name
      • Hostname/identifier
      • Location
      • Authentication code
      • Display orientation
      • Assign playlist (optional)

  5. Deploy

    • Click "Create & Deploy Player" button
    • Player created in database with Auth Code
    • Code automatically deployed to remote host:
      • Directory created at /opt/kiwy-signage
      • Repository cloned
      • Installation scripts executed
    • Success message shows Auth Code for player configuration
    • Redirects to players list

🔧 Technical Details

Deployment Process

User submits form
    ↓
Player created in DigiServer database
    ↓
SSH credentials validated
    ↓
Create deployment directory on remote
    ↓
Clone/pull Kiwy-Signage repository
    ↓
Detect installation script (install.sh, setup.sh, etc.)
    ↓
Execute installation script
    ↓
Return status with Auth Code

Error Handling

  • SSH Connection Refused → Display specific error
  • Authentication Failed → Show auth error
  • Directory Creation Failed → Log error, continue
  • Git Clone Failed → Show git error output
  • Installation Script Not Found → Graceful skip with warning
  • Timeout → Show timeout error with timestamp

Security Considerations

  • SSH credentials NOT stored in database
  • Credentials passed via sshpass (in-memory only)
  • StrictHostKeyChecking disabled for initial connection
  • All operations logged with deployment status
  • Credentials cleared after deployment

Timeouts

  • SSH connection test: 10 seconds
  • Git operations: 120 seconds
  • Installation script: 300 seconds
  • Total deployment: ~10 minutes maximum

📋 API Rate Limits

  • POST /api/deploy/test-ssh: 30 requests per 60 seconds
  • POST /api/deploy/player: 20 requests per 60 seconds

🐳 Container Changes

  • Image: enterprise_digital-platform-digiserver-app:latest
  • New dependencies: sshpass, git, openssh-client
  • Healthcheck: Now accepts 302 redirects (working correctly)
  • All 7 services healthy and running

✨ Features

  • Fully automated code deployment
  • Step-by-step status tracking
  • Graceful error handling

Player Management

  • Easy player creation with one form
  • Automatic code provisioning

  • Detailed error messages
  • Logging of all operations
  • Easy to extend or modify

📝 Example Workflow

Step 1: SSH Test
Input: hostname=192.168.1.100, user=pi, password=raspberry
Output: ✓ Connected!

Step 2: Fill Player Form
- Display Name: "Office Reception Display"

- Quick Connect Code: "OFFICE123"

Step 3: Submit
- Player "office-display-01" created
- Code deployed to /opt/kiwy-signage
- Auth Code provided: abc123xyz...
