# On-Demand Development Environments for Alga PSA

## Project Overview

This project aims to create an automated system for spinning up on-demand development environments for Alga PSA pull requests in Kubernetes. Each environment will be namespaced by GitHub PR number and include a complete development stack with code server, mirrord for remote development, and AI automation capabilities.

## Architecture

```
GitHub PR � Helm Deploy � K8s Namespace � Development Environment
    �                        �                    �
  PR-123      �    alga-pr-123-ns    �    [Code Server + PSA + AI Tools]
```

### Core Components

### CLI Implementation Details

#### Environment Creation Flow
1. Validate PR number and fetch branch info
2. Generate unique namespace and resource names
3. Deploy Helm chart with PR-specific values
4. Wait for deployment readiness
5. Setup port forwarding (optional)
6. Display access URLs and connection info

#### Environment Management
- Health checks via Kubernetes API
- Resource usage monitoring
- Automatic scaling based on usage
- Cleanup policies for inactive environments

### Security Considerations

#### Network Isolation
- Each PR environment in separate namespace
- Network policies for service isolation
- Ingress with authentication/authorization
- Rate limiting and resource quotas

#### Access Control
- Integration with existing authentication
- Role-based access to environments
- Audit logging for environment access
- Secure secrets management

#### Data Protection
- Isolated databases per environment
- No production data in dev environments
- Encrypted storage for persistent volumes
- Regular backup and cleanup policies

## USAGE EXAMPLES

### Quick Start - Create Environment for PR #123
```bash
# Navigate to project root
cd /path/to/alga-psa

# Create development environment for PR 123
nu cli/main.nu dev-env-create 123 --branch feature/my-feature --edition ce

# Check status
nu cli/main.nu dev-env-status 123

# Connect with port forwarding
nu cli/main.nu dev-env-connect 123 --port-forward --code-server

# Clean up when done
nu cli/main.nu dev-env-destroy 123
```

### Typical Workflow
1. **Developer creates PR** - PR #456 for feature branch `feature/new-ui`
2. **Create environment**: `nu cli/main.nu dev-env-create 456 --branch feature/new-ui`
3. **Access via browser**: Environment will be available at `https://456.dev.alga.nineminds.com`
4. **Develop and test** using:
   - Code Server: Full VSCode environment with project loaded
   - AI Automation: Testing and validation tools
   - Full PSA stack: Database, Redis, all services running
5. **Share with team**: Send environment URL for review/testing
6. **Clean up**: `nu cli/main.nu dev-env-destroy 456` when PR is merged

### CLI Command Reference
```bash
# List all environments
nu cli/main.nu dev-env-list

# Create with AI automation disabled
nu cli/main.nu dev-env-create 789 --no-ai

# Force destroy without confirmation
nu cli/main.nu dev-env-destroy 789 --force

# Get detailed status for specific environment
nu cli/main.nu dev-env-status 123

# Connect and open code server automatically
nu cli/main.nu dev-env-connect 123 --code-server
```
