59 Semaphore Workflows und Automatisierung

59.1 Job Scheduling (geplante Läufe, Cron)

59.1.1 Grundlagen des Job-Schedulings

Job-Scheduling in Semaphore ermöglicht die zeitbasierte Automatisierung von Playbook-Ausführungen ohne manuelle Intervention. Dies ist essentiell für wiederkehrende Wartungsaufgaben, Backups und regelmäßige Systemüberprüfungen.

59.1.1.1 Scheduler-Komponenten

Scheduling-Engine:

Semaphore Scheduler:
├── Cron-Parser: Verarbeitung von Cron-Expressions
├── Job-Queue: Warteschlange für geplante Jobs
├── Execution-Engine: Ausführung zum geplanten Zeitpunkt
├── Conflict-Resolution: Behandlung überlappender Jobs
└── Failure-Handling: Retry-Logik und Fehlerbehandlung

59.1.1.2 Template-Scheduling-Konfiguration

Schedule-Einstellungen:

Template: "Daily System Backup"
├── Schedule: Enabled
├── Cron Expression: "0 2 * * *"
├── Timezone: Europe/Berlin
├── Max Parallel: 1
├── Retry Policy: 3 attempts
└── Timeout: 4 hours

59.1.2 Cron-Expression-Syntax

59.1.2.1 Standard Cron-Format

Cron-Feldstruktur:

┌───────────── Minute (0-59)
│ ┌─────────── Hour (0-23)
│ │ ┌───────── Day of Month (1-31)
│ │ │ ┌─────── Month (1-12)
│ │ │ │ ┌───── Day of Week (0-7, Sunday = 0 or 7)
│ │ │ │ │
* * * * *

59.1.2.2 Praktische Cron-Beispiele

Häufige Scheduling-Pattern:

# Täglich um 2:00 Uhr
0 2 * * *

# Jeden Sonntag um 3:30 Uhr
30 3 * * 0

# Werktags um 8:00 und 18:00 Uhr
0 8,18 * * 1-5

# Alle 15 Minuten
*/15 * * * *

# Jeden ersten Tag des Monats um Mitternacht
0 0 1 * *

# Alle 6 Stunden
0 */6 * * *

# Montag bis Freitag um 9:00 Uhr
0 9 * * 1-5

59.1.2.3 Erweiterte Cron-Expressions

Komplexe Zeitpläne:

# Alle 2 Stunden zwischen 8:00 und 18:00 Uhr, werktags
0 8-18/2 * * 1-5

# Jeden 15. und letzten Tag des Monats
0 12 15,L * *

# Jeden zweiten Mittwoch
0 14 * * 3#2

# Quartalsmäßig (Januar, April, Juli, Oktober)
0 6 1 1,4,7,10 *

59.1.3 Scheduling-Strategien

59.1.3.1 Backup-Scheduling

Gestaffeltes Backup-System:

Backup Schedule Matrix:
├── Inkrementelle Backups
│   ├── Expression: "0 1 * * 1-6"
│   ├── Frequency: Täglich außer Sonntag
│   └── Duration: ~30 Minuten
├── Vollbackups
│   ├── Expression: "0 2 * * 0"
│   ├── Frequency: Sonntags
│   └── Duration: ~4 Stunden
└── Archivierung
    ├── Expression: "0 4 1 * *"
    ├── Frequency: Monatlich
    └── Duration: ~2 Stunden

59.1.3.2 Wartungsfenster-Scheduling

Koordinierte Systemwartung:

Maintenance Window: "Monthly Patching"
├── Pre-Maintenance Checks
│   ├── Schedule: "0 20 * * 6"  # Samstag 20:00
│   ├── Tasks: System validation, backup verification
│   └── Duration: 1 Stunde
├── System Patching
│   ├── Schedule: "0 2 * * 0"   # Sonntag 02:00
│   ├── Tasks: Package updates, security patches
│   └── Duration: 3 Stunden
└── Post-Maintenance Validation
    ├── Schedule: "0 6 * * 0"   # Sonntag 06:00
    ├── Tasks: Service verification, health checks
    └── Duration: 1 Stunde

59.1.4 Timezone-Handling

59.1.4.1 Timezone-Konfiguration

Globale Timezone-Einstellungen:

{
  "default_timezone": "Europe/Berlin",
  "supported_timezones": [
    "UTC",
    "Europe/Berlin",
    "Europe/London",
    "America/New_York",
    "America/Los_Angeles",
    "Asia/Tokyo"
  ]
}

59.1.4.2 Template-spezifische Timezones

Multi-Region-Scheduling:

Template: "Global Infrastructure Monitoring"
├── Europe Region
│   ├── Schedule: "0 3 * * *"
│   ├── Timezone: Europe/Berlin
│   └── Target: European data centers
├── US East Region
│   ├── Schedule: "0 3 * * *"
│   ├── Timezone: America/New_York
│   └── Target: US East data centers
└── Asia Pacific Region
    ├── Schedule: "0 3 * * *"
    ├── Timezone: Asia/Tokyo
    └── Target: APAC data centers

59.1.5 Job-Overlap-Management

59.1.5.1 Concurrent Execution Control

Overlap-Prevention-Strategien:

Execution Policy Options:
├── Skip if Running
│   ├── Behavior: Neue Ausführung wird übersprungen
│   ├── Use Case: Backup-Jobs, lange laufende Tasks
│   └── Risk: Verpasste Ausführungen
├── Queue if Running
│   ├── Behavior: Job wird in Warteschlange eingereiht
│   ├── Use Case: Kritische, sequentielle Tasks
│   └── Risk: Aufstauende Warteschlange
├── Kill and Restart
│   ├── Behavior: Laufender Job wird beendet
│   ├── Use Case: Monitoring, Health Checks
│   └── Risk: Unvollständige Operationen
└── Parallel Execution
    ├── Behavior: Multiple Instanzen erlaubt
    ├── Use Case: Unabhängige, parallelisierbare Tasks
    └── Risk: Ressourcenkonflikte

59.2 Pipelines und Abhängigkeiten zwischen Jobs

59.2.1 Pipeline-Konzepte

Pipeline-Workflows ermöglichen die Orchestrierung komplexer, mehrstufiger Automatisierungsprozesse mit definierten Abhängigkeiten und Bedingungen zwischen einzelnen Jobs.

59.2.1.1 Pipeline-Architektur

Workflow-Struktur:

CI/CD Pipeline Example:
├── Stage 1: Pre-Deployment
│   ├── Code Quality Check
│   ├── Security Scan
│   └── Dependency Validation
├── Stage 2: Build & Test
│   ├── Application Build (depends on Stage 1)
│   ├── Unit Tests (parallel to Build)
│   └── Integration Tests (depends on Build)
├── Stage 3: Staging Deployment
│   ├── Deploy to Staging (depends on Stage 2)
│   ├── Smoke Tests (depends on Deploy)
│   └── Performance Tests (parallel to Smoke Tests)
└── Stage 4: Production Deployment
    ├── Blue-Green Switch (depends on Stage 3)
    ├── Health Verification (depends on Switch)
    └── Rollback Capability (conditional)

59.2.2 Job-Abhängigkeiten definieren

59.2.2.1 Template-Verkettung

Dependency-Configuration:

Template: "Application Deployment Pipeline"
├── Job 1: "Pre-Deployment Validation"
│   ├── Dependencies: None (Entry Point)
│   ├── Success Condition: All tasks successful
│   └── Failure Action: Stop pipeline
├── Job 2: "Database Migration"
│   ├── Dependencies: Job 1 (successful)
│   ├── Parallel Execution: False
│   └── Timeout: 30 minutes
├── Job 3: "Application Deployment"
│   ├── Dependencies: Job 2 (successful)
│   ├── Variables: Inherited from Job 2
│   └── Rollback: Job 4 on failure
└── Job 4: "Post-Deployment Tests"
    ├── Dependencies: Job 3 (successful)
    ├── Parallel Tests: Health, Performance, Security
    └── Report Generation: Always execute

59.2.2.2 Conditional Dependencies

Bedingte Workflow-Ausführung:

# Pipeline-Konfiguration mit Bedingungen
pipeline_stages:
  pre_deployment:
    condition: always
    
  security_scan:
    condition: "{{ environment == 'production' }}"
    depends_on: pre_deployment
    
  staging_deployment:
    condition: "{{ branch == 'main' and security_scan.status == 'success' }}"
    depends_on: [pre_deployment, security_scan]
    
  production_deployment:
    condition: "{{ staging_deployment.status == 'success' and manual_approval == true }}"
    depends_on: staging_deployment
    manual_trigger: required

59.2.3 Pipeline-Patterns

59.2.3.1 Parallel Execution Pattern

Parallele Job-Ausführung:

Parallel Processing Pipeline:
├── Data Processing Branch 1
│   ├── Job A1: Extract Data Source 1
│   ├── Job A2: Transform Data 1 (depends on A1)
│   └── Job A3: Load to Warehouse 1 (depends on A2)
├── Data Processing Branch 2
│   ├── Job B1: Extract Data Source 2
│   ├── Job B2: Transform Data 2 (depends on B1)
│   └── Job B3: Load to Warehouse 2 (depends on B2)
└── Convergence Point
    ├── Job C1: Data Validation (depends on A3, B3)
    ├── Job C2: Report Generation (depends on C1)
    └── Job C3: Notification (depends on C2)

59.2.3.2 Fan-out/Fan-in Pattern

Verteilte Verarbeitung:

# Fan-out Phase: Deployment zu mehreren Umgebungen
fan_out_jobs:
  - name: "Deploy to Development"
    template: "dev-deployment"
    depends_on: "build"
    
  - name: "Deploy to Staging"
    template: "staging-deployment"
    depends_on: "build"
    
  - name: "Deploy to QA"
    template: "qa-deployment"
    depends_on: "build"

# Fan-in Phase: Konsolidierung der Ergebnisse
fan_in_jobs:
  - name: "Integration Tests"
    template: "integration-testing"
    depends_on: ["Deploy to Development", "Deploy to Staging", "Deploy to QA"]
    
  - name: "Release Report"
    template: "release-reporting"
    depends_on: "Integration Tests"

59.2.4 Pipeline-State Management

59.2.4.1 Job-Status-Propagation

Status-Weitergabe zwischen Jobs:

Job Status Handling:
├── Success: Nachfolgende Jobs werden ausgeführt
├── Warning: Pipeline fortsetzung mit Warnung
├── Failure: Pipeline stoppt, Rollback-Jobs werden ausgeführt
├── Timeout: Retry-Logic oder Pipeline-Abbruch
└── Manual Intervention: Pipeline pausiert für Benutzerentscheidung

Status Variables:
├── previous_job_status: "success|warning|failure|timeout"
├── pipeline_health_score: 0-100 (basierend auf Job-Erfolg)
├── execution_context: Übergabe von Variablen zwischen Jobs
└── rollback_required: Boolean flag für Rollback-Initiierung

59.2.4.2 Pipeline-Artifacts

Datenübertragung zwischen Jobs:

# Job 1: Artefakt-Generierung
- name: Generate deployment package
  archive:
    path: /app/build/
    dest: "/tmp/{{ pipeline_id }}/deployment-{{ version }}.tar.gz"
    
- name: Store pipeline artifacts
  copy:
    src: "/tmp/{{ pipeline_id }}/"
    dest: "{{ semaphore_artifacts_path }}/{{ pipeline_id }}/"

# Job 2: Artefakt-Nutzung
- name: Retrieve deployment package
  unarchive:
    src: "{{ semaphore_artifacts_path }}/{{ pipeline_id }}/deployment-{{ version }}.tar.gz"
    dest: /opt/application/
