# Cron Job Support Bundles - Product Requirements Document ## Executive Summary **Cron Job Support Bundles** introduces automated, scheduled collection of support bundles to transform troubleshooting from reactive to proactive. Instead of manually running `support-bundle` commands when issues occur, users can schedule automatic collection at regular intervals, enabling continuous monitoring, trend analysis, and proactive issue detection. This feature pairs with the auto-upload functionality to create a complete automation pipeline: **schedule → collect → upload → analyze → alert**. ## Problem Statement ### Current Pain Points for End Customers 1. **Reactive Troubleshooting**: DevOps teams collect support bundles only after incidents occur, missing critical pre-incident diagnostic data 2. **Manual Intervention Burden**: Every support bundle collection requires someone to remember and manually execute commands 3. **Inconsistent Monitoring**: No standardized way for operations teams to collect diagnostic data regularly across their environments 4. **Missing Historical Context**: Without regular collection, troubleshooting lacks historical context and trend analysis for their specific infrastructure 5. **Alert Fatigue**: Operations teams don't know when systems are degrading until complete failure occurs in their environments ### Business Impact for End Customers - **Increased MTTR**: Longer time to resolution due to lack of pre-incident data from their environments - **Operations Team Frustration**: Reactive processes create poor experience for DevOps/SRE teams - **Engineering Time Waste**: Manual collection processes consume valuable engineering time from customer teams - **SLA Risk**: Cannot proactively prevent issues that impact their customer-facing services ## Objectives ### Primary Goals 1. **Customer-Controlled Automation**: Enable end customers to schedule their own unattended support bundle collection 2. **Customer-Driven Proactive Monitoring**: Empower operations teams to shift from reactive to proactive troubleshooting 3. **Customer-Owned Historical Analysis**: Help customers build their own diagnostic data history for trend analysis 4. **Customer-Managed Automation**: Complete automation under customer control from collection through upload and analysis 5. **Customer-Centric Enterprise Features**: Support enterprise customer deployments with their compliance and security requirements ### Success Metrics - **Customer Adoption Rate**: 30%+ of end customers enable self-managed scheduled collection within 6 months - **Customer Issue Prevention**: 25% reduction in customer critical incidents through their proactive detection - **Customer MTTR Improvement**: 40% faster customer resolution times with their historical context - **Customer Satisfaction**: Improved operational experience ratings from DevOps/SRE teams ## Scope & Requirements ### In Scope - **Core Scheduling Engine**: Cron-syntax scheduling with persistent job storage - **CLI Management Interface**: Commands to create, list, modify, and delete scheduled jobs - **Daemon Mode**: Background service for continuous operation - **Integration with Auto-Upload**: Seamless handoff to the auto-upload functionality - **Job Persistence**: Survive process restarts and system reboots - **Configuration Management**: Flexible configuration for different environments - **Security & Compliance**: RBAC integration and audit logging ### Out of Scope - **Kubernetes CronJob Integration**: Using native K8s CronJobs (for now - future consideration) - **Advanced Analytics**: Complex trend analysis (handled by separate analysis pipeline) - **GUI Interface**: Web-based management (CLI-first approach) - **Multi-Cluster Management**: Single cluster focus initially ### Must-Have Requirements 1. **Customer-Controlled Reliable Scheduling**: End customers can create jobs that execute reliably according to their chosen cron schedules 2. **Customer-Visible Failure Handling**: Robust error handling with clear visibility to customer operations teams 3. **Customer-Managed Resource Limits**: Allow customers to control resource usage and prevent exhaustion in their environments 4. **Customer Security Control**: Respect customer RBAC permissions and provide secure credential storage under customer control 5. **Customer Observability**: Comprehensive logging and monitoring capabilities accessible to customer operations teams ### Should-Have Requirements 1. **Customer-Flexible Configuration**: Support for different collection profiles that customers can customize for their environments 2. **Customer-Managed Job Dependencies**: Allow customers to set up job chaining and dependency management for their workflows 3. **Customer-Controlled Notifications**: Enable customers to configure alerts for job failures or critical findings in their systems 4. **Customer-Beneficial Performance Optimization**: Efficient resource utilization that respects customer infrastructure constraints ### Could-Have Requirements 1. **Advanced Scheduling**: Complex schedules beyond basic cron syntax 2. **Multi-Tenancy**: Isolation between different teams/namespaces 3. **Job Templates**: Reusable job configuration templates 4. **Historical Analytics**: Built-in trend analysis capabilities ## Technical Architecture ### System Overview ``` ┌─────────────────┐ ┌──────────────────┐ ┌─────────────────┐ │ CLI Client │───▶│ Scheduler Core │───▶│ Job Executor │ └─────────────────┘ └──────────────────┘ └─────────────────┘ │ │ ▼ ▼ ┌──────────────────┐ ┌─────────────────┐ │ Job Storage │ │ Support Bundle │ └──────────────────┘ │ Collection │ └─────────────────┘ │ ▼ ┌─────────────────┐ │ Auto-Upload │ │ (auto-upload) │ └─────────────────┘ ``` ### Core Components #### 1. Scheduler Core (`pkg/scheduler/`) - **Purpose**: Central orchestration engine for scheduled jobs - **Responsibilities**: - Parse and validate cron expressions - Maintain job queue and execution timeline - Handle job lifecycle management - Coordinate with job storage and execution components #### 2. Job Storage (`pkg/scheduler/storage/`) - **Purpose**: Persistent storage for scheduled jobs and execution history - **Implementation**: File-based JSON/YAML storage with atomic operations - **Data Model**: Job definitions, execution logs, configuration state #### 3. Job Executor (`pkg/scheduler/executor/`) - **Purpose**: Execute scheduled support bundle collections - **Integration**: Leverage existing `pkg/supportbundle/` collection pipeline - **Features**: Concurrent execution limits, timeout handling, result processing #### 4. Scheduler Daemon (`pkg/scheduler/daemon/`) - **Purpose**: Background service for continuous operation - **Features**: Process lifecycle management, signal handling, graceful shutdown - **Deployment**: Single-instance daemon with file-based coordination #### 5. CLI Interface (`cmd/support-bundle/cli/schedule/`) - **Purpose**: User interface for schedule management - **Commands**: `create`, `list`, `delete`, `modify`, `daemon`, `status` - **Integration**: Extends existing `support-bundle` CLI structure ### Data Models #### Job Definition ```go type ScheduledJob struct { ID string `json:"id"` Name string `json:"name"` Description string

Customer creates their first scheduled job ```bash # Customer's DevOps team sets up daily collection at 2 AM in their timezone support-bundle schedule create daily-check \ --cron "0 2 * * *" \ # Customer chooses 2 AM --namespace myapp \ # Customer's application namespace --auto \ # Auto-discover customer's resources --upload enabled # Auto-upload to vendor portal ``` ### 2. Customer starts the scheduler daemon on their infrastructure ```bash # Runs on customer's systems support-bundle schedule daemon start ``` ### 3. Customer monitors their jobs ```bash # Customer lists all their scheduled jobs support-bundle schedule list # Customer checks their daemon status support-bundle schedule daemon status # Customer views their execution history support-bundle schedule history daily-check ``` ``` ##### 6.1.2 Advanced Configuration Guide ```markdown # Advanced Scheduling Configuration ## Cron Expression Examples - `0 */6 * * *` - Every 6 hours - `0 0 * * 1` - Weekly on Monday at midnight - `0 0 1 * *` - Monthly on the 1st at midnight - `*/15 * * * *` - Every 15 minutes - `0 9-17 * * 1-5` - Hourly during business hours (Mon-Fri, 9 AM-5 PM) ## Upload Providers ### Customer's AWS S3 ```bash # Customer configures upload to their own S3 bucket support-bundle schedule create customer-job \ --upload enabled # Auto-upload to vendor portal ``` ### Customer's Google Cloud Storage ```bash # Customer uses their own GCS bucket and service account support-bundle schedule create customer-job \ --upload enabled # Auto-upload to vendor portal ``` ### Customer's Custom HTTP Endpoint ```bash # Customer uploads to their own API endpoint support-bundle schedule create customer-job \ --upload enabled # Auto-upload to vendor portal ``` ## Customer Resource Limits ```yaml # Customer configures limits for their environment: ~/.troubleshoot/scheduler/config.yaml defaultMaxConcurrent: 3 # Customer sets concurrent job limit for their system defaultTimeout: 30m # Customer sets timeout based on their cluster size maxBundleSize: 1GB # Customer sets bundle size limits for their storage ``` ``` #### 6.2 Operations Guide ##### 6.2.1 Deployment Guide ```markdown # Production Deployment Guide ## System Requirements - Linux/macOS/Windows server - 2+ GB RAM (4+ GB recommended for large clusters) - 10+ GB disk space for bundle storage - Network access to Kubernetes API and upload destinations ## Installation ### Binary Installation ```bash # Download latest release wget https://github.com/replicatedhq/troubleshoot/releases/latest/download/support-bundle chmod +x support-bundle sudo mv support-bundle /usr/local/bin/ ``` ### Systemd Service ```ini # /etc/systemd/system/troubleshoot-scheduler.service [Unit] Description=Troubleshoot Scheduler Daemon After=network.target [Service] Type=forking User=troubleshoot Group=troubleshoot ExecStart=/usr/local/bin/support-bundle schedule daemon start ExecReload=/usr/local/bin/support-bundle schedule daemon reload ExecStop=/usr/local/bin/support-bundle schedule daemon stop Restart=always RestartSec=10 [Install] WantedBy=multi-user.target ``` ### Configuration ```yaml # /etc/troubleshoot/scheduler.yaml defaultTimezone: "America/New_York" maxJobsPerUser: 10 defaultRetentionDays: 30 storageBackend: "file" storageConfig: baseDir: "/var/lib/troubleshoot/scheduler" backupEnabled: true backupInterval: "24h" logLevel: "info" metricsEnabled: true metricsPort: 9090 ``` ``` ##### 6.2.2 Monitoring & Alerting ```markdown # Monitoring Configuration ## Prometheus Metrics The scheduler daemon exposes metrics on `:9090/metrics`: ### Key Metrics - `troubleshoot_scheduler_jobs_total` - Total number of jobs - `troubleshoot_scheduler_jobs_active` - Currently executing jobs - `troubleshoot_scheduler_executions_total` - Total executions - `troubleshoot_scheduler_execution_duration_seconds` - Execution time - `troubleshoot_scheduler_bundle_size_bytes` - Bundle size distribution ### Grafana Dashboard Import dashboard ID: TBD (to be published) ## Log Analysis ### Important Log Patterns - Job execution failures: `level=error component=executor` - Upload failures: `level=error component=uploader` - Resource exhaustion: `level=warn message="resource limit reached"` ### Alerting Rules ```yaml groups: - name: troubleshoot-scheduler rules: - alert: SchedulerJobsFailing expr: increase(troubleshoot_scheduler_executions_total{status="failed"}[5m]) > 0 labels: severity: warning annotations: summary: "Troubleshoot scheduler jobs are failing" - alert: SchedulerDaemonDown expr: up{job="troubleshoot-scheduler"} == 0 for: 2m labels: severity: critical annotations: summary: "Troubleshoot scheduler daemon is down" ``` ``` ## Security Considerations ### Customer Authentication & Authorization - **Customer RBAC Integration**: Scheduler respects customer's existing Kubernetes RBAC permissions - **Customer User Isolation**: Jobs run with customer user's permissions, no privilege escalation beyond customer's access - **Customer Audit Logging**: All job operations logged with customer user context for their compliance needs - **Customer Credential Security**: Customer upload credentials encrypted at rest on customer systems ### Network Security - **TLS**: All external communications use TLS - **Firewall**: Minimal network requirements (K8s API + upload endpoints) - **Secrets Management**: Integration with K8s secrets and external secret stores ### Customer Data Protection - **Customer-Controlled Redaction**: Automatic PII/credential redaction before upload to customer's chosen destinations - **Customer Encryption**: Bundle encryption in transit and at rest using customer's encryption preferences - **Customer Retention**: Customer-configurable data retention and secure deletion policies - **Customer Compliance**: Support for customer's GDPR, SOC2, HIPAA compliance requirements ## Error Handling & Recovery ### Failure Scenarios 1. **Job Execution Failure** - Automatic retry with exponential backoff - Failed job notifications - Detailed error logging 2. **Upload Failure** - Retry mechanism with different endpoints - Local bundle preservation - Alert administrators 3. **Daemon Crash** - Automatic restart via systemd - Job state recovery from persistent storage - In-progress job cleanup and restart 4. **Resource Exhaustion** - Resource limit enforcement - Job queuing and throttling - Automatic cleanup of old bundles ### Customer Recovery Procedures ```bash # Customer can manually recover their jobs support-bundle schedule recover --execution-id # Customer restarts their daemon with state recovery support-bundle schedule daemon restart --recover # Customer cleans up their storage support-bundle schedule cleanup --repair --older-than 30d ``` ## Implementation Progress & Timeline ### Phase 1: Core Scheduling Engine ✅ **COMPLETED** **Status: 100% Complete -
