Automation Guide

Automate checkpointing workflows with SnapHook webhooks and CI/CD integration.

SnapHook Webhooks

Creating SnapHooks

1. Navigate to SnapHook > Create SnapHook
2. Configure:

   Name: production-snaphook
   Cluster: production-cluster
   Webhook URL: https://snap.company.com/webhook
   Namespace: snap
   

Webhook Events

• Pod Created: Trigger on new pod creation
• Pod Updated: Trigger on pod changes
• Scheduled: Time-based triggers
• Custom: Custom event triggers

CI/CD Integration

GitHub Actions

name: SNAP Checkpoint
on:
  push:
    branches: [ main ]
jobs:
  checkpoint:
    runs-on: ubuntu-latest
    steps:
      - name: Create Checkpoint
        run: |
          curl -X POST "$/checkpoint/kubelet/checkpoint" \
            -H "Authorization: Bearer $" \
            -H "Content-Type: application/json" \
            -d '{
              "pod_name": "app-pod",
              "namespace": "default",
              "cluster_name": "production"
            }'

Jenkins Pipeline

pipeline {
    agent any
    stages {
        stage('Checkpoint') {
            steps {
                script {
                    def response = httpRequest(
                        url: 'http://snap-api:8000/checkpoint/kubelet/checkpoint',
                        httpMode: 'POST',
                        contentType: 'APPLICATION_JSON',
                        requestBody: '{"pod_name": "app-pod", "namespace": "default"}'
                    )
                }
            }
        }
    }
}

Automated Workflows

Disaster Recovery

• Scheduled checkpoints: Regular backup creation
• Cross-region sync: Automatic replication
• Health checks: Monitor checkpoint integrity

Application Migration

• Blue-green deployment: Checkpoint before switch
• Rollback capability: Instant rollback from checkpoints
• State preservation: Maintain application state

Monitoring and Alerting

Metrics Collection

• Checkpoint success rate: Track checkpoint reliability
• Performance metrics: Monitor checkpoint timing
• Storage usage: Track checkpoint storage

Alerting Rules

• Failed checkpoints: Alert on checkpoint failures
• Storage threshold: Alert on storage limits
• Performance degradation: Alert on slow checkpoints
