restarts**, ensuring your Splunk clusters remain healthy and available during configuration changes, secret updates, and scale operations. + +## What This Feature Does For You + +### Automatic Restart Management + +Your Splunk pods will automatically restart when needed, without manual intervention: + +- **Secret Changes**: When you update secrets (passwords, certificates), the operator detects the change and safely restarts affected pods one at a time +- **Configuration Updates**: Pods that need restart after configuration changes are automatically identified and restarted +- **Zero Manual Intervention**: No need to manually delete pods or trigger restarts + +### Safe Scale-Down Operations + +When scaling down your cluster, the operator ensures proper cleanup: + +- **Data Protection**: Indexer data is safely replicated before the pod is removed +- **Graceful Decommission**: Indexers are properly decommissioned from the cluster +- **Automatic Cleanup**: Persistent volumes are automatically deleted during scale-down (but preserved during restarts) + +### High Availability During Restarts + +Your cluster stays available during maintenance: + +- **One Pod at a Time**: Only one pod restarts at a time, maintaining cluster quorum +- **Respects Pod Disruption Budgets**: Ensures minimum availability requirements are met +- **Health Checks**: Waits for pods to become healthy before proceeding to the next + +## Key Benefits + +### 1. Reduced Operational Burden +**Before**: You had to manually monitor and restart pods when configurations changed +**Now**: The operator automatically detects and handles restarts for you + +### 2. Safer Operations +**Before**: Scaling down could leave orphaned data or improperly decommissioned nodes +**Now**: Automatic cleanup ensures proper decommissioning and data protection + +### 3. Better Availability +**Before**: Cluster-wide rolling restarts could cause service disruptions +**Now**: Individual pod restarts minimize impact on cluster availability + +### 4.

Monitor During Operations +Always watch the operator logs during: +- First-time operations in a new environment +- Large scale-down operations (> 3 pods) +- Critical production changes + +### 3. Verify Before Scale-Down +Before scaling down, ensure: +- Replication factor allows for the reduction +- Search factor allows for the reduction +- Sufficient capacity remains for your data volume + +### 4. Test in Non-Production First +For major changes: +- Test secret updates in dev/staging first +- Validate scale-down operations in lower environments +- Verify restart timing with your data volumes + +## Troubleshooting + +### Pod Stuck in Terminating + +**Symptom**: Pod shows `Terminating` for more than 10 minutes + +**Possible Causes**: +- Decommission is waiting for data replication +- Network issues preventing cluster communication +- Operator is processing another pod + +**Resolution**: +```bash +# Check operator logs +kubectl logs deployment/splunk-operator-controller-manager -n splunk-operator + +# Check pod events +kubectl describe pod + +# Check if decommission is complete +kubectl exec -- curl -k -u admin:password \ + https://localhost:8089/services/cluster/slave/info +``` + +### Restart Not Triggering + +**Symptom**: Changed secret but pods are not restarting + +**Possible Causes**: +- Pod Disruption Budget is blocking eviction +- Another pod is currently restarting +- Secret reference doesn't match pod configuration + +**Resolution**: +```bash +# Check PDB status +kubectl get pdb + +# Check if eviction is blocked +kubectl get events --sort-by='.lastTimestamp' + +# Verify secret reference +kubectl get pod -o yaml | grep -A 5 secretRef +``` + +### Scale-Down Not Completing + +**Symptom**: Scale-down initiated but pod won't terminate + +**Possible Causes**: +- Replication factor prevents scale-down +- Data replication is in progress +- Cluster manager is unreachable + +**Resolution**: +```bash +# Check cluster manager status +kubectl exec -- curl -k -u admin:password \ + https://localhost:8089/services/cluster/master/peers + +# Check replication status +kubectl logs | grep -i replication + +# Verify cluster health +kubectl exec -- curl -k -u admin:password \ + https://localhost:8089/services/cluster/master/health +``` + +## Configuration Options + +### Pod Disruption Budget + +Control how many pods can be unavailable during restarts: + +```yaml +apiVersion: policy/v1 +kind: PodDisruptionBudget +metadata: + name: splunk-indexer-pdb +spec: + minAvailable: 2 # Minimum 2 indexers must be available + selector: + matchLabels: + app.kubernetes.io/component: indexer +``` + +### Restart Annotations + +View or modify pod intent annotations: + +```bash +# View current intent +kubectl get pod \ + -o jsonpath='{.metadata.annotations.splunk\.com/pod-intent}' + +# Manually mark for scale-down (advanced use only) +kubectl annotate pod \ + splunk.com/pod-intent=scale-down --overwrite +``` + +**⚠️ Warning**: Manual annotation changes should only be done by advanced users and may cause unexpected behavior. + +## Feature Compatibility + +### Supported Cluster Types +- ✅ IndexerCluster +- ✅ SearchHeadCluster +- ✅ Standalone (secret change detection only) + +### Supported Operations +- ✅ Secret updates → Automatic rolling restart +- ✅ Scale-down → Safe decommission with PVC cleanup +- ✅ Scale-up → Automatic pod creation with finalizers +- ✅ Manual restart triggers → Per-pod eviction + +### Requirements +- Kubernetes 1.21+ +- Splunk Operator 3.0+ +- Splunk Enterprise 8.0+ + +## Frequently Asked Questions + +### Q: Will my data be lost during restart? +**A**: No. Restarts preserve all persistent volumes. Only scale-down operations delete PVCs for removed pods. + +### Q: How long does a restart take? +**A**: Typically 5-10 minutes per pod, depending on pod size and startup time. The operator waits for health checks before proceeding. + +### Q: Can I restart multiple pods simultaneously? +**A**: No. The operator enforces one pod at a time to maintain cluster availability and respect Pod Disruption Budgets. + +### Q: What happens if the operator crashes during a restart? +**A**: The finalizer prevents pod deletion until cleanup completes. When the operator restarts, it will continue the cleanup process. + +### Q: Can I disable automatic restarts? +**A**: Currently, automatic restart on secret changes is enabled by default. You can control the pace by adjusting Pod Disruption Budgets. + +### Q: Will restarts affect search performance? +**A**: Yes, temporarily. During restart, one indexer/search head is unavailable. However, the cluster continues serving traffic with remaining pods. + +## Getting Help + +If you encounter issues: + +1. **Check operator logs**: Most issues are visible in operator logs +2. **Review pod events**: `kubectl describe pod ` +3. **Verify cluster status**: Check Splunk UI for cluster health +4. **Consult documentation**: Review the full operator documentation +5. **Contact support**: Reach out to Splunk support with operator logs + +## Summary + +The per-pod rolling restart feature provides: +- ✅ Automatic restart management for secret and configuration changes +- ✅ Safe scale-down with proper decommissioning +- ✅ High availability during maintenance operations +- ✅ Reduced operational burden through automation + +This feature is enabled by default in Splunk Operator 3.0+ and requires no additional configuration for basic usage. diff --git a/pkg/splunk/client/enterprise.go b/pkg/splunk/client/enterprise.go index 8bc36b08a..df3830324 100644 ---
