 ## 🔁 What is Reloader?
 
-Reloader is a Kubernetes controller that automatically triggers rollouts of workloads (like Deployments, StatefulSets, and more) whenever referenced `Secrets` or `ConfigMaps` are updated.
+Reloader is a Kubernetes controller that automatically triggers rollouts of workloads (like Deployments, StatefulSets, and more) whenever referenced `Secrets`, `ConfigMaps` or **optionally CSI-mounted secrets** are updated.
 
 In a traditional Kubernetes setup, updating a `Secret` or `ConfigMap` does not automatically restart or redeploy your workloads. This can lead to stale configurations running in production, especially when dealing with dynamic values like credentials, feature flags, or environment configs.

-By default, Reloader uses the **rollout** strategy — it updates the pod template to trigger a new rollout. This works well in most cases, but it can cause problems if you're using GitOps tools like ArgoCD, which detect this as configuration drift.
+Note: This is only applicable when using [Argo Rollouts](https://argoproj.github.io/argo-rollouts/). It is ignored for standard Kubernetes `Deployments`, `StatefulSets`, or `DaemonSets`. To use this feature, Argo Rollouts support must be enabled in Reloader (for example via --is-argo-rollouts=true).
+
+By default, Reloader triggers the Argo Rollout controller to perform a standard rollout by updating the pod template. This works well in most cases, however, because this modifies the workload spec, GitOps tools like ArgoCD will detect this as "Configuration Drift" and mark your application as OutOfSync.
 
 To avoid that, you can switch to the **restart** strategy, which simply restarts the pod without changing the pod template.

 1. ✅ Your deployment references multiple ConfigMaps or Secrets that may be updated at the same time.
 1. ✅ You want to minimize unnecessary rollouts and reduce downtime caused by back-to-back configuration changes.
 
+### 8. 🔐 CSI Secret Provider Support
+
+Reloader supports the [Secrets Store CSI Driver](https://secrets-store-csi-driver.sigs.k8s.io/), which allows mounting secrets from external secret stores (like AWS Secrets Manager, Azure Key Vault, HashiCorp Vault) directly into pods.
+Unlike Kubernetes Secret objects, CSI-mounted secrets do not always trigger native Kubernetes update events. Reloader solves this by watching CSI status resources and restarting affected workloads when mounted secret versions change.
+
+#### How it works
+
+When secret rotation is enabled, the Secrets Store CSI Driver updates a Kubernetes resource called: `SecretProviderClassPodStatus`
+
+This resource reflects the currently mounted secret versions for a pod.
+Reloader watches these updates and triggers a rollout when a change is detected.
+
+#### Prerequisites
+
+- Secrets Store CSI Driver must be installed in your cluster
+- Secret rotation enabled in the CSI driver.
+- Enable CSI integration in Reloader: `--enable-csi-integration=true`
+
+#### Annotations for CSI-mounted Secrets
+
+| Annotation                                                                   | Description                                                                                                                 |

+| `secretproviderclass.reloader.stakater.com/auto: 'true'`                     | CSI Discovery: Specifically watches for updates to all SecretProviderClasses used by the workload (CSI driver integration). |
+| `secretproviderclass.reloader.stakater.com/reload: "my-secretproviderclass"` | Targeted Reload: Only reloads the workload when the specifically named SecretProviderClass(es) are updated.                 |
+
+Reloader monitors changes at the **per-secret level** by watching the `SecretProviderClassPodStatus`. Make sure each secret you want to monitor is properly defined with a `secretKey` in your `SecretProviderClass`:
+
+```yaml
+apiVersion: secrets-store.csi.x-k8s.io/v1
+kind: SecretProviderClass
+metadata:
+  name: vault-reloader-demo
+  namespace: test
+spec:
+  provider: vault
+  parameters:
+    vaultAddress: "http://vault.vault.svc:8200"
+    vaultSkipTLSVerify: "true"
+    roleName: "demo-role"
+    objects: |
+      - objectName: "password"
+        secretPath: "secret/data/reloader-demo"
+        secretKey: "password"
+```
+
+***Important***: Reloader tracks changes to individual secrets (identified by `secretKey`). If your SecretProviderClass doesn't specify `secretKey` for each object, Reloader may not detect updates correctly.
+
+#### Notes & Limitations
+
+Reloader reacts to CSI status changes, not direct updates to external secret stores
+Secret rotation must be enabled in the CSI driver for updates to be detected
+CSI limitations (such as `subPath` mounts) still apply and may require pod restarts
+If secrets are synced to Kubernetes Secret objects, standard Reloader behavior applies and CSI support may not be required

+# Reloader Load Test Framework
+
+This framework provides A/B comparison testing between two Reloader container images.
+
+## Overview
+
+The load test framework:
+1. Creates a local kind cluster (1 control-plane + 6 worker nodes)
+2. Deploys Prometheus for metrics collection
+3. Loads the provided Reloader container images into the cluster
+4. Runs standardized test scenarios (S1-S13)
+5. Collects metrics via Prometheus scraping
+6. Generates comparison reports with pass/fail criteria
+
+## Prerequisites
+
+- Docker or Podman
+- kind (Kubernetes in Docker)
+- kubectl
+- Go 1.22+
+
+## Building
+
+```bash
+cd test/loadtest
+go build -o loadtest ./cmd/loadtest
+```
+
+## Quick Start
+
+```bash
+# Compare two published images (e.g., different versions)
+./loadtest run \
+  --old-image=stakater/reloader:v1.0.0 \
+  --new-image=stakater/reloader:v1.1.0
+
+# Run a specific scenario
+./loadtest run \
+  --old-image=stakater/reloader:v1.0.0 \
+  --new-image=stakater/reloader:v1.1.0 \
+  --scenario=S2 \
+  --duration=120
+
+# Test only a single image (no comparison)
+./loadtest run --new-image=myregistry/reloader:dev
+
+# Use local images built with docker/podman
+./loadtest run \
+  --old-image=localhost/reloader:baseline \
+  --new-image=localhost/reloader:feature-branch
+
+# Skip cluster creation (use existing kind cluster)
+./loadtest run \
+  --old-image=stakater/reloader:v1.0.0 \
+  --new-image=stakater/reloader:v1.1.0 \
+  --skip-cluster
+
+# Run all scenarios in parallel on 4 clusters (faster execution)
+./loadtest run \
+  --new-image=localhost/reloader:dev \
+  --parallelism=4
+
+# Run all 13 scenarios in parallel (one cluster per scenario)
+./loadtest run \

+
+## Metrics Reference
+
+This section explains each metric collected during load tests, what it measures, and what different values might indicate.
+
+### Counter Metrics (Totals)
+
+#### `reconcile_total`
+**What it measures:** The total number of reconciliation loops executed by the controller.
+
+**What it indicates:**
+- **Higher in new vs old:** The new controller-runtime implementation may batch events differently. This is often expected behavior, not a problem.
+- **Lower in new vs old:** Better event batching/deduplication. Controller-runtime's work queue naturally deduplicates events.
+- **Expected behavior:** The new implementation typically has *fewer* reconciles due to intelligent event batching.
+
+#### `action_total`
+**What it measures:** The total number of reload actions triggered (rolling restarts of Deployments/StatefulSets/DaemonSets).
+
+**What it indicates:**
+- **Should match expected value:** Both implementations should trigger the same number of reloads for the same workload.
+- **Lower than expected:** Some updates were missed - potential bug or race condition.
+- **Higher than expected:** Duplicate reloads triggered - inefficiency but not data loss.
+
+#### `reload_executed_total`
+**What it measures:** Successful reload operations executed, labeled by `success=true/false`.
+
+**What it indicates:**
+- **`success=true` count:** Number of workloads successfully restarted.
+- **`success=false` count:** Failed restart attempts (API errors, permission issues).
+- **Should match `action_total`:** If significantly lower, reloads are failing.
+
+#### `workloads_scanned_total`
+**What it measures:** Number of workloads (Deployments, etc.) scanned when checking for ConfigMap/Secret references.
+
+**What it indicates:**
+- **High count:** Controller is scanning many workloads per reconcile.
+- **Expected behavior:** Should roughly match the number of workloads × number of reconciles.
+- **Optimization signal:** If very high, namespace filtering or label selectors could help.
+
+#### `workloads_matched_total`
+**What it measures:** Number of workloads that matched (reference the changed ConfigMap/Secret).
+
+**What it indicates:**
+- **Should match `reload_executed_total`:** Every matched workload should be reloaded.
+- **Higher than reloads:** Some matched workloads weren't reloaded (potential issue).
+
+#### `errors_total`
+**What it measures:** Total errors encountered, labeled by error type.
+
+**What it indicates:**
+- **Should be 0:** Any errors indicate problems.
+- **Common causes:** API server timeouts, RBAC issues, resource conflicts.
+- **Critical metric:** Non-zero errors in production should be investigated.
+
+### API Efficiency Metrics (REST Client)
+
+These metrics track Kubernetes API server calls made by Reloader. Lower values indicate more efficient operation with less API server load.
+
+#### `rest_client_requests_total`
+**What it measures:** Total number of HTTP requests made to the Kubernetes API server.
+
+**What it indicates:**
+- **Lower is better:** Fewer API calls means less load on the API server.
+- **High count:** May indicate inefficient caching or excessive reconciles.
+- **Comparison use:** Shows overall API efficiency between implementations.
+
+#### `rest_client_requests_get`
+**What it measures:** Number of GET requests (fetching individual resources or listings).
+
+**What it indicates:**
+- **Includes:** Fetching ConfigMaps, Secrets, Deployments, etc.
+- **Higher count:** More frequent resource fetching, possibly due to cache misses.
+- **Expected behavior:** Controller-runtime's caching should reduce GET requests compared to direct API calls.
+
+#### `rest_client_requests_patch`
+**What it measures:** Number of PATCH requests (partial updates to resources).
+
+**What it indicates:**
+- **Used for:** Rolling restart annotations on workloads.
+- **Should correlate with:** `reload_executed_total` - each reload typically requires one PATCH.
+- **Lower is better:** Fewer patches means more efficient batching or deduplication.
+
+#### `rest_client_requests_put`
+**What it measures:** Number of PUT requests (full resource updates).
+
+**What it indicates:**
+- **Used for:** Full object replacements (less common than PATCH).
+- **Should be low:** Most updates use PATCH for efficiency.
+- **High count:** May indicate suboptimal update strategy.
+
+#### `rest_client_requests_errors`
+**What it measures:** Number of failed API requests (4xx/5xx responses).
+
+**What it indicates:**
+- **Should be 0:** Errors indicate API server issues or permission problems.
+- **Common causes:** Rate limiting, RBAC issues, resource conflicts, network issues.
+- **Non-zero:** Investigate API server logs and Reloader permissions.
+
+### Latency Metrics (Percentiles)
+
+All latency metrics are reported in **seconds**. The report shows p50 (median), p95, and p99 percentiles.
+
+#### `reconcile_duration (s)`
+**What it measures:** Time spent inside each reconcile loop, from start to finish.
+
+**What it indicates:**
+- **p50 (median):** Typical reconcile time. Should be < 100ms for good performance.
+- **p95:** 95th percentile - only 5% of reconciles take longer than this.
+- **p99:** 99th percentile - indicates worst-case performance.
+
+**Interpreting differences:**
+- **New higher than old:** Controller-runtime reconciles may do more work per loop but run fewer times. Check `reconcile_total` - if it's lower, this is expected.
+- **Minor differences (< 0.5s absolute):** Not significant for sub-second values.
+
+#### `action_latency (s)`
+**What it measures:** End-to-end time from ConfigMap/Secret change detection to workload restart triggered.
+
+**What it indicates:**
+- **This is the user-facing latency:** How long users wait for their config changes to take effect.
+- **p50 < 1s:** Excellent - most changes apply within a second.
+- **p95 < 5s:** Good - even under load, changes apply quickly.
+- **p99 > 10s:** May need investigation - some changes take too long.
+
+**What affects this:**
+- API server responsiveness
+- Number of workloads to scan
+- Concurrent updates competing for resources
+
+### Understanding the Report
+
+#### Report Columns
+
+```
+Metric                           Old          New   Expected  Old✓  New✓   Status
+------                           ---          ---   --------  ----  ----   ------
+action_total                  100.00       100.00        100     ✓     ✓     pass
+action_latency_p95 (s)          0.15         0.04          -     -     -     pass
+```
+
+- **Old/New:** Measured values from each implementation
+- **Expected:** Known expected value (for throughput metrics)
+- **Old✓/New✓:** Whether the value is within 15% of expected (✓ = yes, ✗ = no, - = no expected value)
+- **Status:** pass/fail based on comparison thresholds
+
+#### Pass/Fail Logic
+
+| Metric Type | Pass Condition |
+|-------------|----------------|
+| Throughput (action_total, reload_executed_total) | New value within 15% of expected |
+| Latency (p50, p95, p99) | New not more than threshold% worse than old, OR absolute difference < minimum threshold |
+| Errors | New ≤ Old (ideally both 0) |
+| API Efficiency (rest_client_requests_*) | New ≤ Old (lower is better), or New not more than 50% higher |
+
+#### Latency Thresholds
+
+Latency comparisons use both percentage AND absolute thresholds to avoid false failures:
+
+| Metric | Max % Worse | Min Absolute Diff |
+|--------|-------------|-------------------|
+| p50 | 100% | 0.5s |
+| p95 | 100% | 1.0s |
+| p99 | 100% | 1.0s |
+
+**Example:** If old p50 = 0.01s and new p50 = 0.08s:
+- Percentage difference: +700% (would fail % check)
+- Absolute difference: 0.07s (< 0.5s threshold)
+- **Result: PASS** (both values are fast enough that the difference doesn't matter)
+
+### Resource Consumption Metrics
+
+These metrics track CPU, memory, and Go runtime resource usage. Lower values generally indicate more efficient operation.
+
+#### Memory Metrics
+
+| Metric | Description | Unit |
+|--------|-------------|------|
+| `memory_rss_mb_avg` | Average RSS (resident set size) memory | MB |
+| `memory_rss_mb_max` | Peak RSS memory during test | MB |
+| `memory_heap_mb_avg` | Average Go heap allocation | MB |
+| `memory_heap_mb_max` | Peak Go heap allocation | MB |
+
+**What to watch for:**
+- **High RSS:** May indicate memory leaks or inefficient caching
+- **High heap:** Many objects being created (check GC metrics)
+- **Growing over time:** Potential memory leak
+
+#### CPU Metrics
+
+| Metric | Description | Unit |
+|--------|-------------|------|
+| `cpu_cores_avg` | Average CPU usage rate | cores |
+| `cpu_cores_max` | Peak CPU usage rate | cores |
+
+**What to watch for:**
+- **High CPU:** Inefficient algorithms or excessive reconciles
+- **Spiky max:** May indicate burst handling issues
+
+#### Go Runtime Metrics
+
+| Metric | Description | Unit |
+|--------|-------------|------|
+| `goroutines_avg` | Average goroutine count | count |
+| `goroutines_max` | Peak goroutine count | count |
+| `gc_pause_p99_ms` | 99th percentile GC pause time | ms |
+
+**What to watch for:**
+- **High goroutines:** Potential goroutine leak or unbounded concurrency
+- **High GC pause:** Large heap or allocation pressure
+
+### Scenario-Specific Expectations
+
+| Scenario | Key Metrics to Watch | Expected Behavior |
+|----------|---------------------|-------------------|
+| S1 (Burst) | action_latency_p99, cpu_cores_max, goroutines_max | Should handle bursts without queue backup |
+| S2 (Fan-Out) | reconcile_total, workloads_matched, memory_rss_mb_max | One CM change → 50 workload reloads |
+| S3 (High Cardinality) | reconcile_duration, memory_heap_mb_avg | Many namespaces shouldn't increase memory |
+| S4 (No-Op) | action_total = 0, cpu_cores_avg should be low | Minimal resource usage for no-op |
+| S5 (Churn) | errors_total, goroutines_avg | Graceful handling, no goroutine leak |
+| S6 (Restart) | All metrics captured | Metrics survive controller restart |
+| S7 (API Pressure) | errors_total, cpu_cores_max, goroutines_max | No errors under concurrent load |
+| S8 (Large Objects) | memory_rss_mb_max, gc_pause_p99_ms | Large ConfigMaps don't cause OOM or GC issues |
+| S9 (Multi-Workload) | reload_executed_total per type | All workload types (Deploy, STS, DS) reload |
+| S10 (Secrets) | reload_executed_total, workloads_matched | Both Secrets and ConfigMaps trigger reloads |
+| S11 (Annotation) | workload annotations present | Deployments get `last-reloaded-from` annotation |
+| S12 (Pause) | reload_executed_total << updates | Pause-period reduces reload frequency |
+| S13 (Complex) | reload_executed_total | All reference types trigger reloads |
+
+### Troubleshooting
+
+#### New implementation shows 0 for all metrics
+- Check if Prometheus is scraping the new Reloader pod
+- Verify pod annotations: `prometheus.io/scrape: "true"`
+- Check Prometheus targets: `http://localhost:9091/targets`
+
+#### Metrics don't match expected values
+- Verify test ran to completion (check logs)
+- Ensure Prometheus scraped final metrics (18s wait after test)
+- Check for pod restarts during test (metrics reset on restart - handled by `increase()`)
+
+#### High latency in new implementation
+- Check Reloader pod resource limits
+- Look for API server throttling in logs
+- Compare `reconcile_total` - fewer reconciles with higher duration may be normal
+
+#### REST client errors are non-zero
+- **Common causes:**
+  - Optional CRD schemes registered but CRDs not installed (e.g., Argo Rollouts, OpenShift DeploymentConfig)
+  - API server rate limiting under high load
+  - RBAC permissions missing for certain resource types
+- **Argo Rollouts errors:** If you see ~4 errors per test, ensure `--enable-argo-rollouts=false` if not using Argo Rollouts
+- **OpenShift errors:** Similarly, ensure DeploymentConfig support is disabled on non-OpenShift clusters
+
+#### REST client requests much higher in new implementation
+- Check if caching is working correctly
+- Look for excessive re-queuing in controller logs
+- Compare `reconcile_total` - more reconciles naturally means more API calls
+

+
+## Building Local Images for Testing
+
+If you want to test local code changes:
+
+```bash
+# Build the new Reloader image from current source
+docker build -t localhost/reloader:dev -f Dockerfile .
+
+# Build from a different branch/commit
+git checkout feature-branch
+docker build -t localhost/reloader:feature -f Dockerfile .
+
+# Then run comparison
+./loadtest run \
+  --old-image=stakater/reloader:v1.0.0 \
+  --new-image=localhost/reloader:feature
+```
+
+## Interpreting Results
+
+### PASS
+All metrics are within acceptable thresholds. The new implementation is comparable or better than the old one.
+
+### FAIL
+One or more metrics exceeded thresholds. Review the specific metrics:
+- **Latency degradation**: p95/p99 latencies are significantly higher
+- **Missed reloads**: `reload_executed_total` differs significantly
+- **Errors increased**: `errors_total` is higher in new version
+
+### Investigation
+
+If tests fail, check:
+1. Pod logs: `kubectl logs -n reloader-new deployment/reloader` (or check `results/<scenario>/new/reloader.log`)
+2. Resource usage: `kubectl top pods -n reloader-new`
+3. Events: `kubectl get events -n reloader-test`
+
+## Parallel Execution
+
+The `--parallelism` option enables running scenarios on multiple kind clusters simultaneously, significantly reducing total test time.
+
+### How It Works
+
+1. **Multiple Clusters**: Creates N kind clusters named `reloader-loadtest-0`, `reloader-loadtest-1`, etc.
+2. **Separate Prometheus**: Each cluster gets its own Prometheus instance with a unique port (9091, 9092, etc.)
+3. **Worker Pool**: Scenarios are distributed to workers via a channel, with each worker running on its own cluster
+4. **Independent Execution**: Each scenario runs in complete isolation with no resource contention
+
+### Usage
+
+```bash
+# Run 4 scenarios at a time (creates 4 clusters)
+./loadtest run --new-image=my-image:tag --parallelism=4
+
+# Run all 13 scenarios in parallel (creates 13 clusters)
+./loadtest run --new-image=my-image:tag --parallelism=13 --scenario=all
+```
+
+### Resource Requirements
+
+Parallel execution requires significant system resources:
+
+| Parallelism | Clusters | Est. Memory | Est. CPU |
+|-------------|----------|-------------|----------|
+| 1 (default) | 1 | ~4GB | 2-4 cores |
+| 4 | 4 | ~16GB | 8-16 cores |
+| 13 | 13 | ~52GB | 26-52 cores |
+
+### Notes
+
+- The `--skip-cluster` option is not supported with parallelism > 1
+- Each worker loads images independently, so initial setup takes longer
+- All results are written to the same `--results-dir` with per-scenario subdirectories
+- If a cluster setup fails, remaining workers continue with available clusters
+- Parallelism automatically reduces to match scenario count if set higher
+
+## CI Integration
+
+### GitHub Actions
+
+Load tests can be triggered on pull requests by commenting `/loadtest`:
+
+```
+/loadtest
+```
+
+This will:
+1. Build a container image from the PR branch
+2. Run all load test scenarios against it
+3. Post results as a PR comment
+4. Upload detailed results as artifacts
+
+### Make Target
+
+Run load tests locally or in CI:
+
+```bash
+# From repository root
+make loadtest
+```
+
+This builds the container image and runs all scenarios with a 60-second duration.
