CodeRabbit Incident Runbook

Overview

Rapid incident response procedures for CodeRabbit-related outages.

Prerequisites

• Access to CodeRabbit dashboard and status page
• kubectl access to production cluster
• Prometheus/Grafana access
• Communication channels (Slack, PagerDuty)

Severity Levels

Level	Definition	Response Time	Examples
P1	Complete outage	< 15 min	CodeRabbit API unreachable
P2	Degraded service	< 1 hour	High latency, partial failures
P3	Minor impact	< 4 hours	Webhook delays, non-critical errors
P4	No user impact	Next business day	Monitoring gaps

Quick Triage

# 1. Check CodeRabbit status
curl -s https://status.coderabbit.com | jq

# 2. Check our integration health
curl -s https://api.yourapp.com/health | jq '.services.coderabbit'

# 3. Check error rate (last 5 min)
curl -s localhost:9090/api/v1/query?query=rate(coderabbit_errors_total[5m])

# 4. Recent error logs
kubectl logs -l app=coderabbit-integration --since=5m | grep -i error | tail -20

Decision Tree

CodeRabbit API returning errors?
├─ YES: Is status.coderabbit.com showing incident?
│   ├─ YES → Wait for CodeRabbit to resolve. Enable fallback.
│   └─ NO → Our integration issue. Check credentials, config.
└─ NO: Is our service healthy?
    ├─ YES → Likely resolved or intermittent. Monitor.
    └─ NO → Our infrastructure issue. Check pods, memory, network.

Immediate Actions by Error Type

401/403 - Authentication

# Verify API key is set
kubectl get secret coderabbit-secrets -o jsonpath='{.data.api-key}' | base64 -d

# Check if key was rotated
# → Verify in CodeRabbit dashboard

# Remediation: Update secret and restart pods
kubectl create secret generic coderabbit-secrets --from-literal=api-key=NEW_KEY --dry-run=client -o yaml | kubectl apply -f -
kubectl rollout restart deployment/coderabbit-integration

429 - Rate Limited

# Check rate limit headers
curl -v https://api.coderabbit.com 2>&1 | grep -i rate

# Enable request queuing
kubectl set env deployment/coderabbit-integration RATE_LIMIT_MODE=queue

# Long-term: Contact CodeRabbit for limit increase

500/503 - CodeRabbit Errors

# Enable graceful degradation
kubectl set env deployment/coderabbit-integration CODERABBIT_FALLBACK=true

# Notify users of degraded service
# Update status page

# Monitor CodeRabbit status for resolution

Instructions

Step 1: Quick Triage

Run the triage commands to identify the issue source.

Step 2: Follow Decision Tree

Determine if the issue is CodeRabbit-side or internal.

Step 3: Execute Immediate Actions

Apply the appropriate remediation for the error type.

Step 4: Communicate Status

Update internal and external stakeholders.

Output

• Issue identified and categorized
• Remediation applied
• Stakeholders notified
• Evidence collected for postmortem

Error Handling

Issue	Cause	Solution
Can't reach status page	Network issue	Use mobile or VPN
kubectl fails	Auth expired	Re-authenticate
Metrics unavailable	Prometheus down	Check backup metrics
Secret rotation fails	Permission denied	Escalate to admin

Examples

One-Line Health Check

curl -sf https://api.yourapp.com/health | jq '.services.coderabbit.status' || echo "UNHEALTHY"
