node capabilities upfront + +### Configuration Management + +1. **Validation**: Always validate before applying +2. **Metadata**: Include descriptive reasons and tags +3. **Testing**: Test in staging before production +4. **Rollback Plan**: Know your rollback revision before deploying + +### Gradual Rollout + +1. **Start Small**: Begin with 1-5% canary deployment +2. **Monitor Closely**: Watch metrics during each stage +3. **Wait Times**: Allow sufficient time between stages +4. **Health Checks**: Configure appropriate health check intervals +5. **Rollback Ready**: Be prepared to rollback quickly + +### Circuit Breaker + +1. **Threshold Tuning**: Start conservative, tune based on metrics +2. **Timeout**: Set timeout based on expected recovery time +3. **Monitoring**: Alert on state changes +4. **Testing**: Test circuit breaker behavior in staging + +### Security + +1. **mTLS**: Use mutual TLS in production +2. **Key Rotation**: Rotate API keys regularly +3. **Least Privilege**:

Configuration + +1. Check node heartbeat status +2. Verify node labels match rollout target +3. Check rollout status and current stage +4. Review audit logs for authorization issues + +### Rollout Stuck + +1.
