Deployment

Safe deployment strategies and procedures for DotClaude configurations.

Deployment Philosophy

Safety First Approach

All DotClaude deployments follow these principles:

• Non-Destructive - Never overwrite without backup
• Reversible - Always provide rollback capability
• Incremental - Apply changes gradually
• Validated - Test before system-wide deployment

Deployment Stages

1. Preparation - Environment setup and validation
2. Backup - Preserve existing configurations
3. Testing - Validate in isolated environment
4. Application - Deploy configurations safely
5. Verification - Confirm successful deployment
6. Documentation - Record changes and procedures

Deployment Methods

Individual Package Deployment

Deploy specific packages independently:

# Single package deployment
./scripts/stow-package.sh git

# With explicit testing
./scripts/test-config.sh git
./scripts/stow-package.sh git
./scripts/health-check.sh

Progressive Deployment

Apply packages in logical order:

# Phase 1: Foundation
./scripts/stow-package.sh environment
./scripts/stow-package.sh aliases

# Phase 2: Core Tools  
./scripts/stow-package.sh git
./scripts/stow-package.sh zsh

# Phase 3: Advanced Features
./scripts/stow-package.sh tmux
./scripts/stow-package.sh neovim

Full System Deployment

Complete DotClaude installation:

# Automated full deployment
./scripts/deploy-all.sh

# Manual full deployment
for package in environment aliases git zsh tmux neovim; do
    ./scripts/stow-package.sh "$package"
done

Pre-Deployment Checklist

System Requirements

• [ ] GNU Stow installed
• [ ] Git available
• [ ] Target shell (zsh) installed
• [ ] Required dependencies present

Environment Validation

• [ ] Backup space available
• [ ] User permissions sufficient
• [ ] No conflicting processes running
• [ ] System stability confirmed

Configuration Readiness

• [ ] Package integrity verified
• [ ] Dependencies resolved
• [ ] Conflicts identified and planned
• [ ] Rollback procedures tested

Deployment Procedures

Standard Deployment Process

1. Pre-flight Check

   ./scripts/health-check.sh --pre-deploy

2. Create Backup

   ./scripts/backup.sh

3. Test Configuration

   ./scripts/test-config.sh <package>

4. Deploy Package

   ./scripts/stow-package.sh <package>

5. Verify Deployment

   ./scripts/health-check.sh --post-deploy

Emergency Deployment

For urgent fixes or critical updates:

# Quick deployment with minimal testing
./scripts/backup.sh
./scripts/stow-package.sh <package> --force
./scripts/health-check.sh --quick

Environment-Specific Deployments

Development Environment

• Full feature set enabled
• Debug logging active
• Extensive testing
• Regular backup cycles

export DOTCLAUDE_ENV=development
./scripts/deploy-all.sh --dev-mode

Production Environment

• Stable configurations only
• Minimal logging
• Conservative feature set
• Automated backup scheduling

export DOTCLAUDE_ENV=production
./scripts/deploy-all.sh --production

Testing Environment

• Isolated deployment
• Experimental features
• Comprehensive logging
• Easy rollback

export DOTCLAUDE_ENV=testing
./scripts/deploy-all.sh --test-mode

Deployment Strategies

Blue-Green Deployment

Maintain two complete environments:

# Deploy to green environment
./scripts/deploy-to-env.sh green

# Test green environment
./scripts/test-env.sh green

# Switch to green environment
./scripts/switch-env.sh green

# Remove blue environment
./scripts/cleanup-env.sh blue

Rolling Deployment

Apply changes gradually across packages:

# Deploy packages one at a time
for package in "${packages[@]}"; do
    ./scripts/deploy-package.sh "$package"
    ./scripts/verify-package.sh "$package"
    sleep 5  # Allow stabilization
done

Canary Deployment

Test with subset of functionality:

# Deploy to limited scope
./scripts/deploy-canary.sh --packages="git,aliases"

# Monitor and validate
./scripts/monitor-canary.sh

# Full deployment if successful
./scripts/promote-canary.sh

Deployment Automation

Continuous Deployment

Automated deployment pipeline:

# .github/workflows/deploy.yml
on:
  push:
    branches: [main]
jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Deploy DotClaude
        run: ./scripts/ci-deploy.sh

Scheduled Deployments

Regular configuration updates:

# Crontab entry for weekly updates
0 2 * * 0 cd ~/dotfiles && ./scripts/update-all.sh

Post-Deployment Tasks

Verification Procedures

1. Functionality Testing - Verify all features work
2. Performance Monitoring - Check system performance
3. Integration Testing - Ensure cross-package compatibility
4. User Acceptance - Confirm user satisfaction

Documentation Updates

• Update deployment logs
• Record configuration changes
• Document any issues encountered
• Update user documentation

Monitoring Setup

• Configure health monitoring
• Set up performance alerts
• Enable error tracking
• Schedule regular checks

Rollback Procedures

Automatic Rollback

System detects issues and reverts:

# Health check triggers rollback
./scripts/health-check.sh --auto-rollback

Manual Rollback

User-initiated reversion:

# Rollback specific package
./scripts/restore.sh git 2024-06-18

# Full system rollback
./scripts/restore-all.sh 2024-06-18

Emergency Rollback

Critical system recovery:

# Emergency restore to last known good
./scripts/emergency-restore.sh

# Nuclear option - restore all from backup
./scripts/restore-everything.sh --emergency

Deployment Troubleshooting

Common Issues

• Permission Errors - Check file permissions and ownership
• Symlink Conflicts - Resolve overlapping configurations
• Dependency Issues - Ensure all requirements met
• Configuration Errors - Validate syntax and settings

Diagnostic Commands

# Check deployment status
./scripts/deployment-status.sh

# Validate configuration integrity
./scripts/validate-deployment.sh

# Debug deployment issues
./scripts/debug-deployment.sh --verbose

Recovery Strategies

1. Partial Rollback - Revert problematic packages only
2. Configuration Repair - Fix issues in place
3. Clean Deployment - Remove and redeploy
4. Emergency Recovery - Full system restoration

Best Practices

Planning

• Always plan deployments during low-activity periods
• Have rollback procedures ready
• Test thoroughly in non-production environments
• Communicate changes to users

Execution

• Follow documented procedures exactly
• Monitor system during deployment
• Keep detailed logs of all actions
• Verify each step before proceeding

Post-Deployment

• Conduct thorough testing
• Monitor system performance
• Address any issues promptly
• Update documentation and procedures
