Continuous Deployment in TuskLang - Bash Guide

🚀 Revolutionary Continuous Deployment Configuration

Continuous deployment (CD) in TuskLang transforms your configuration files into intelligent, automated deployment systems. No more manual deployments or fragile release processes—everything lives in your TuskLang configuration with dynamic deployment strategies, automatic rollbacks, and intelligent environment management.

> "We don't bow to any king" – TuskLang CD breaks free from traditional deployment constraints and brings modern automation to your Bash applications.

🚀 Core CD Directives

Basic CD Setup

#cd: enabled                        # Enable CD
#cd-enabled: true                   # Alternative syntax
#cd-strategy: blue-green            # Deployment strategy
#cd-environments: staging,prod      # Target environments
#cd-rollback: auto                  # Auto-rollback on failure
#cd-monitoring: true                # Enable deployment monitoring

Advanced CD Configuration

#cd-canary: true                    # Enable canary deployments
#cd-approval: required              # Require approval for production
#cd-artifacts: true                 # Enable artifact management
#cd-notifications: slack            # Notification channel
#cd-health-check: true              # Enable health checks
#cd-schedule: "0 2   *"           # Scheduled deployments

🔧 Bash CD Implementation

Basic CD Pipeline Manager

            deployments: 0,
            successful: 0,
            failed: 0,
            rollbacks: 0
        }
    }
    
    deploy(environment, version) {
        if (!this.enabled) return
        this.stats.deployments++
        const result = this.executeDeployment(environment, version)

        } else {
            this.stats.failed++
            if (this.rollback === 'auto') {
                this.rollback(environment)
            }
        }
        this.sendNotification(result)
    }
    
    executeDeployment(environment, version) {
        // Implementation for deployment execution
        return { success: true }
    }
    
    rollback(environment) {
        this.stats.rollbacks++
        // Implementation for rollback

🚨 Troubleshooting CD

Common Issues and Solutions

1. Deployment Issues

Debug deployment
debug_cd_deployment() {
    local environment="$1"
    local version="$2"
    echo "Debugging CD deployment to $environment with version $version"
    execute_deployment_strategy "blue-green" "$environment" "$version"
}

🔒 Security Best Practices

CD Security Checklist

Security validation
validate_cd_security() {
    echo "Validating CD security configuration..."
    # Check approval requirements
    if [[ "${cd_approval}" == "required" ]]; then
        echo "✓ CD approval required for production"
    else
        echo "⚠ CD approval not required for production"
    fi
    # Check environment isolation
    if [[ "${cd_environment_isolation}" == "true" ]]; then
        echo "✓ CD environment isolation enabled"
    else
        echo "⚠ CD environment isolation not enabled"
    fi
    # Check rollback configuration
    if [[ "${cd_rollback}" == "auto" ]]; then
        echo "✓ CD auto-rollback enabled"
    else
        echo "⚠ CD auto-rollback not enabled"
    fi

📈 Performance Optimization Tips

CD Performance Checklist

Performance validation
validate_cd_performance() {
    echo "Validating CD performance configuration..."
    # Check deployment speed
    local deployment_time="${cd_deployment_time:-300}" # seconds
    if [[ "$deployment_time" -le 600 ]]; then
        echo "✓ Fast deployment time ($deployment_time s)"
    else
        echo "⚠ Deployment time may be slow ($deployment_time s)"
    fi
    # Check health check frequency
    local health_check_interval="${cd_health_check_interval:-10}" # seconds
    if [[ "$health_check_interval" -le 30 ]]; then
        echo "✓ Frequent health checks ($health_check_interval s)"
    else
        echo "⚠ Health checks may be infrequent ($health_check_interval s)"
    fi
    # Check canary deployment
    if [[ "${cd_canary}" == "true" ]]; then
        echo "✓ Canary deployment enabled"
    else
        echo "⚠ Canary deployment not enabled"
