Debug openstack-k8s-operators Operator

This skill provides comprehensive debugging and development workflows for openstack-k8s-operators operators, following openstack-k8s-operators best practices.

Development Workflow

When debugging or developing an operator, I will:

1. Development Checks: Run full development workflow with make targets
2. Code Quality: Pre-commit hooks, linting, and syntax validation
3. Build Verification: Test compilation and manifest generation
4. Test Execution: Run complete test suites or focused tests
5. Deployment Analysis: Check running operator pods and resources
6. Runtime Debugging: Analyze logs, events, and runtime issues

Development Commands

Complete Workflow

• Pre-commit checks, syntax and style validation
• Run make manifests && make generate
• Verify operator compilation (make build)

Testing

• Execute make test
• Run specific tests with Ginkgo focus
• Generate test coverage reports

Quality Assurance

• Code style and quality checks (make golangci)
• Validate dependencies with go mod tidy
• Validate Custom Resource Definitions

Runtime Debugging

For deployed operators, I will also:

1. Environment Check: Verify KUBECONFIG and cluster access
2. Operator Discovery: Find operator pods in standard namespaces
3. Status Analysis: Check deployment, pod, and replica set status
4. Log Analysis: Parse logs for errors, warnings, and patterns
5. Resource Inspection: Examine custom resources and their conditions
6. Event Review: Check Kubernetes events for issues
7. RBAC Verification: Ensure proper permissions are in place

When debugging deployed operators:

# Debug specific operator
/debug-operator glance-operator openstack-operators

# General cluster debugging
/debug-operator cluster-check

Automated Analysis

I will automatically:

• Detect if we're in an operator development directory
• Run appropriate development workflow based on context
• Search for operators in standard namespaces (openstack, openstack-operators, openstack-k8s-operators)
• Identify error patterns in logs using regex matching
• Check custom resource status and conditions
• Review recent events for warnings and errors
• Verify RBAC configuration

Usage Examples

Development Mode

When in an operator directory (with Makefile and go.mod):

# Run complete development workflow
/debug-operator

# Focus on specific test
/debug-operator focus-test "Checks the Topology"

# Run only tests
/debug-operator test-only

Workflow Detection

I will automatically:

1. Detect Context: Check if we're in development or runtime mode
2. Run Appropriate Workflow: Development checks vs. runtime debugging
3. Provide Specific Guidance: Targeted recommendations based on findings
4. Create Action Items: Use TodoWrite for tracking fixes and improvements

Integration with openstack-k8s-operators Ecosystem

The skill integrates with:

• openstack-k8s-operators development practices
• lib-common patterns and conventions
• Ginkgo testing framework workflows
• Controller-runtime debugging patterns

Log Analysis

This skill includes advanced log pattern matching. When given a log file or oc output, analyze it for:

Error Patterns

• API Connectivity: Connection refused, dial failures
• RBAC Issues: Permission denied, forbidden access
• Resource Problems: Not found, validation failures
• Runtime Errors: Panics, nil pointer exceptions
• Image Issues: Pull failures, registry access
• Webhook Failures: Admission controller errors

Performance Patterns

• Slow Reconciliation: >30s reconciliation times
• Queue Issues: Large queue depths (>100 items)
• API Latency: Slow Kubernetes API responses
• Resource Conflicts: Optimistic locking failures

OpenStack-Specific Patterns

• Service Failures: Glance, Nova, Cinder, Manila
• Keystone Auth: Authentication/authorization issues
• Database: Connection and SQL errors
• Network: Neutron service problems

Log Analysis Usage

# Analyze collected logs
/debug-operator
oc logs deployment/glance-operator -n openstack-operators > nova.log
# Then ask to analyze the log file

# Multi-pod logs
oc logs -l app=operator --all-containers=true > combined.log

Output includes: error/warning counts, severity classification, timeline view, and remediation suggestions.

Common Issues Detected

• Pod crash loops and restart issues
• Image pull failures
• RBAC permission problems
• Custom resource validation errors
• Controller reconciliation failures
• Resource conflicts and dependencies
• Webhook configuration issues

Always start with this skill for any operator debugging to ensure comprehensive analysis.
