Logic Validation Report

Date: 2026-01-09 Project: AI Stack Deployer

Requirements vs Implementation

Core Requirement

Deploy user AI stacks via Dokploy API when users provide a valid stack name.

Expected Flow

1. User provides stack name (3-20 chars, alphanumeric + hyphens)
2. System validates name (format, reserved words, availability)
3. System creates Dokploy project: ai-stack-{name}
4. System creates Docker application with OpenCode image
5. System configures domain: {name}.ai.flexinit.nl (HTTPS via Traefik wildcard SSL)
6. System triggers deployment
7. User receives URL to access their stack

Implementation Review

✅ Name Validation (src/index.ts:33-58)

• Length: 3-20 characters ✓
• Format: lowercase alphanumeric + hyphens ✓
• No leading/trailing hyphens ✓
• Reserved names check ✓
• Status: CORRECT

✅ API Client Authentication (src/api/dokploy.ts:75)

• Uses x-api-key header (correct for Dokploy API) ✓
• Status: CORRECT (fixed from Bearer token)

✅ Deployment Orchestration (src/index.ts:61-140)

Step 1: Create/Find Project

• Searches for existing project first ✓
• Creates only if not found ✓
• Status: CORRECT

Step 2: Create Application

• Uses correct project ID ✓
• Passes Docker image ✓
• Creates application with proper naming ✓
• Issue: Parameters may not match API expectations (validation failing)
• Status: NEEDS INVESTIGATION

Step 3: Domain Configuration

• Hostname: {name}.ai.flexinit.nl ✓
• HTTPS enabled ✓
• Port: 8080 ✓
• Status: CORRECT

Step 4: Trigger Deployment

• Calls deployApplication(applicationId) ✓
• Status: CORRECT

⚠️ Identified Issues

1. Application Creation Parameters

   • Location: src/api/dokploy.ts:117-129
   • Issue: API returns "Input validation failed"
   • Root Cause: Unknown - API expects different parameters or format
   • Impact: Blocks deployment at step 2

2. Missing Error Recovery

   • No cleanup on partial failure
   • Orphaned resources if deployment fails mid-way
   • Impact: Resource leaks, name conflicts on retry

3. No Idempotency Guarantees

   • Project creation is idempotent (searches first)
   • Application creation is NOT idempotent
   • Domain creation has no duplicate check
   • Impact: Multiple clicks could create duplicate resources

Logic Validation Conclusion

Core Logic: SOUND - The flow matches requirements Implementation: MOSTLY CORRECT with one blocking issue

Blocking Issue: Application.create API call validation failure

• Need to determine correct API parameters
• Requires API documentation or successful example

Recommendation:

1. Investigate application.create API requirements via Swagger UI
2. Add comprehensive error handling and cleanup
3. Implement idempotency checks for all operations
