|
## Rollback Triggers
|
|
|
|
### Automatic Rollback Triggers
|
|
- [ ] Health check failures > 3 consecutive
|
|
- [ ] Error rate > 10% for 5 minutes
|
|
- [ ] P99 latency > 2x baseline for 5 minutes
|
|
- [ ] Critical alert triggered
|
|
|
|
### Manual Rollback Triggers
|
|
- [ ] User-reported critical bug
|
|
- [ ] Data corruption detected
|
|
- [ ] Security vulnerability discovered
|
|
- [ ] Stakeholder decision
|
|
|
|

|
|
|
|
## Pre-Rollback Checklist
|
|
|
|
- [ ] Incident acknowledged and documented
|
|
- [ ] Stakeholders notified of rollback decision
|
|
- [ ] Current state captured (logs, metrics snapshot)
|
|
- [ ] Rollback target version identified
|
|
- [ ] Database state assessed (migrations reversible?)
|
|
|

## Rollback Procedures
|
|
|
|
### Application Rollback
|
|
|
|
#### Option 1: Revert Deployment (Preferred)
|
|
```bash
|
|
# Using CI/CD
|
|
# Trigger previous successful deployment
|
|
|
|
# Manual (if needed)
|
|
git revert <commit-hash>
|
|
git push origin main
|
|
```
|
|
|
|
#### Option 2: Blue-Green Switch
|
|
```bash
|
|
# Switch traffic to previous version
|
|
# [Platform-specific commands]
|
|
```
|
|
|
|
#### Option 3: Feature Flag Disable
|
|
```bash
|
|
# Disable feature flag
|
|
# [Feature flag system commands]
|
|
```
|
|
|
|
### Database Rollback
|
|
|
|
#### If Migration is Reversible
|
|
```bash
|
|
# Run down migration
|
|
# [Migration tool command]
|
|
```
|
|
|
|
#### If Migration is NOT Reversible
|
|
1. [ ] Restore from backup
|
|
2. [ ] Point-in-time recovery to pre-deployment
|
|
3. [ ] **WARNING**: May cause data loss - requires approval
|
|
|
|
### Configuration Rollback
|
|
```bash
|
|
# Restore previous configuration
|
|
# [Config management commands]
|
|
```
|
|
|

|
|
|
|
## Post-Rollback Verification
|
|
|
|
### Immediate (0-5 minutes)
|
|
- [ ] Service responding to health checks
|
|
- [ ] No error spikes in logs
|
|
- [ ] Basic functionality verified
|
|
|
|
### Short-term (5-30 minutes)
|
|
- [ ] All critical paths functional
|
|
- [ ] Error rate returned to baseline
|
|
- [ ] Performance metrics normal
|
|
|
|
### Extended (30-60 minutes)
|
|
- [ ] No delayed issues appearing
|
|
- [ ] User reports resolved
|
|
- [ ] All alerts cleared
|
|

|
## Known Limitations
|
|
|
|
### Cannot Rollback If:
|
|
- [ ] Database migration deleted columns with data

|
- [ ] External API contracts changed
|
|
- [ ] Third-party integrations updated

|
|
|
### Partial Rollback Scenarios
