Driver Pod Configuration Guide + +## Overview + +Starting from Kubeflow Pipelines v2.15, administrators can configure labels and annotations for driver pods to support infrastructure requirements such as Istio service mesh integration. + +## Configuration Methods + +### Method 1: Environment Variables + +Set environment variables in the `ml-pipeline` deployment: + +```yaml +apiVersion: apps/v1 +kind: Deployment +metadata: + name: ml-pipeline + namespace: kubeflow +spec: + template: + spec: + containers: + - name: ml-pipeline-api-server + env: + - name: DRIVER_POD_LABELS + value: | + { + "sidecar.istio.io/inject": "true", + "app.kubernetes.io/component": "kfp-driver" + } + - name: DRIVER_POD_ANNOTATIONS + value: | + { + "prometheus.io/scrape": "true", + "prometheus.io/port": "9090" + } +``` + +### Method 2: ConfigMap + +Use a ConfigMap for centralized configuration: + +```yaml +apiVersion: v1 +kind: ConfigMap +metadata: + name: kfp-driver-config + namespace: kubeflow +data: + driver-config: | + { + "labels": { + "sidecar.istio.io/inject": "true" + }, + "annotations": { + "proxy.istio.io/config": "{\"holdApplicationUntilProxyStarts\": true}" + } + } +``` + +Then reference it in the deployment: + +```yaml +env: + - name: V2_DRIVER_CONFIG + valueFrom: + configMapKeyRef: + name: kfp-driver-config + key: driver-config + optional: true +``` + +### Method 3: Kustomize Overlay + +For production deployments, use the provided Istio overlay: + +```bash +kubectl apply -k manifests/kustomize/overlays/istio-strict-mtls +``` + +## Common Use Cases + +### Istio Service Mesh with STRICT mTLS + +When running KFP in an Istio mesh with STRICT mTLS enabled: + +**Problem**: Driver pods cannot communicate with MinIO and MLMD services. + +**Solution**: Configure driver pods with Istio sidecar injection: + +```json +{ + "labels": { + "sidecar.istio.io/inject": "true", + "app.kubernetes.io/component": "kfp-driver" + }, + "annotations": { + "proxy.istio.io/config": "{\"holdApplicationUntilProxyStarts\": true}", + "traffic.sidecar.istio.io/includeInboundPorts": "*", + "traffic.sidecar.istio.io/excludeOutboundPorts": "15090,15021" + } +} +``` + +### Prometheus Monitoring + +Enable metrics collection from driver pods: + +```json +{ + "annotations": { + "prometheus.io/scrape": "true", + "prometheus.io/port": "9090", + "prometheus.io/path": "/metrics" + } +} +``` + +### Node Selection + +Route driver pods to specific nodes: + +```json +{ + "labels": { + "workload-type": "kfp-driver", + "node-role": "pipeline-execution" + } +} +``` + +## Configuration Reference + +### Supported Environment Variables + +| Variable | Description | Format | Default | +|----------|-------------|--------|---------| +| `DRIVER_POD_LABELS` | Labels to apply to driver pods

+### Reserved Labels + +The following label prefixes are reserved and will be filtered if provided: +- `pipelines.kubeflow.org/` +- `workflows.argoproj.io/` + +## Verification + +### 1. Check Configuration Loading + +View API server logs: + +```bash +kubectl logs deployment/ml-pipeline -n kubeflow | grep -i "driver.*config" +``` + +### 2.

Verify Sidecar Injection (Istio) + +```bash +# Check for istio-proxy container +kubectl get $DRIVER_POD -n kubeflow -o jsonpath='{.spec.containers[*].name}' +# Should include: istio-proxy +``` + +## Troubleshooting + +### Configuration Not Applied + +1. **Check environment variables are set:** + ```bash + kubectl describe deployment ml-pipeline -n kubeflow | grep -A5 "DRIVER_POD" + ``` + +2. **Verify ConfigMap exists (if using):** + ```bash + kubectl get configmap kfp-driver-config -n kubeflow -o yaml + ``` + +3. **Check for parse errors in logs:** + ```bash + kubectl logs deployment/ml-pipeline -n kubeflow | grep -i error + ``` + +### Istio Connection Issues + +1. **Verify sidecar injection:** + ```bash + kubectl get pod -n kubeflow -o yaml | grep sidecar.istio.io/inject + ``` + +2. **Check mTLS status:** + ```bash + istioctl authn tls-check .kubeflow minio-service.kubeflow + ``` + +3. **Review sidecar logs:** + ```bash + kubectl logs -n kubeflow -c istio-proxy + ``` + +## Migration from Earlier Versions + +### From KFP < 2.15 + +No migration required. The feature is disabled by default and only activates when configuration is provided. + +### From PERMISSIVE mTLS Workaround + +If you were using PERMISSIVE mTLS for MinIO/MLMD as a workaround: + +1.
