+# Kubernetes Integration Test Workflows
+
+This directory contains modular GitHub Actions workflows for testing the semantic-router Kubernetes deployment.

+
+## 🔄 Workflow Architecture
+
+The main workflow (`k8s-integration-test.yml`) orchestrates the following modular workflows:
+
+```mermaid
+graph TD
+    A[Main Workflow] --> B[validate-manifests]
+    A --> C[test-with-custom-config]
+    A --> D[security-scan]
+    B --> E[kind-integration-test]
+    E --> F[test-api-functionality]
+    B --> G[summary]
+    C --> G
+    D --> G
+    F --> G
+```
+
+## 📋 Workflow Modules
+
+### 1. **validate-manifests.yml**
+
+- **Purpose**: Validates Kubernetes manifests using kubeconform
+- **Dependencies**: None
+- **Outputs**: Validated manifest artifacts
+
+### 2. **kind-integration-test.yml**
+
+- **Purpose**: Tests deployment in a real kind cluster
+- **Dependencies**: validate-manifests
+- **Features**:
+  - Creates CI-optimized kind cluster
+  - Builds and loads Docker images
+  - Deploys semantic-router
+  - Tests service connectivity
+  - Basic API functionality tests
+
+### 3. **api-functionality-test.yml**
+
+- **Purpose**: Comprehensive API testing with 14 test cases
+- **Dependencies**: kind-integration-test
+- **Features**:
+  - Health check testing
+  - Model endpoint testing
+  - Classification API testing (intent, PII, security)
+  - Batch processing testing
+  - Error handling testing
+  - Performance testing
+  - Multi-category testing
+
+### 4. **config-test.yml**
+
+- **Purpose**: Configuration validation and overlay testing
+- **Dependencies**: validate-manifests
+- **Features**:
+  - Kustomize overlay validation
+  - ConfigMap generation testing
+  - Observability stack validation
+  - AI Gateway configuration validation
+
+### 5. **security-scan.yml**
+
+- **Purpose**: Security scanning of Kubernetes manifests
+- **Dependencies**: validate-manifests
+- **Features**:
+  - Trivy security scanning
+  - Checkov policy scanning
+  - SARIF report generation
+
+## 🚀 Benefits of Modular Design
+
+### **Maintainability**
+
+- Each workflow has a single responsibility
+- Easier to debug and modify individual components
+- Clear separation of concerns
+
+### **Reusability**
+
+- Workflows can be reused in other contexts
+- Easy to add new test scenarios
+- Configurable parameters for different environments
+
+### **Performance**
+
+- Parallel execution where possible
+- Faster feedback on specific failures
+- Reduced resource usage through targeted testing
+
+### **Debugging**
+
+- Isolated failure points
+- Detailed logs for each component
+- Easier to identify and fix issues
+
+## 🔧 Configuration
+
+### **Environment Variables**
+
+```yaml
+env:
+  KIND_VERSION: v0.20.0
+  KUBECTL_VERSION: v1.28.0
+  KUSTOMIZE_VERSION: v5.7.1
+```
+
+### **Workflow Inputs**
+
+Each workflow accepts configurable inputs:
+
+- `kind_version`: Kind cluster version
+- `kustomize_version`: Kustomize version
+- `kubectl_version`: kubectl version
+
+## 📊 Test Coverage
+
+| Test Type            | Coverage    | Status |
+| -------------------- | ----------- | ------ |
+| Manifest Validation  | ✅ Complete | Active |
+| Service Connectivity | ✅ Complete | Active |
+| API Functionality    | ✅ 14 Tests | Active |
+| Configuration        | ✅ Complete | Active |
+| Security Scanning    | ✅ Complete | Active |
+| Error Handling       | ✅ Complete | Active |
+| Performance          | ✅ Complete | Active |
+
+## 🛠️ Usage
+
+### **Running Individual Workflows**
+
+```bash
+# Run only manifest validation
+gh workflow run validate-manifests.yml
+
+# Run only API tests
+gh workflow run api-functionality-test.yml
+```
+
+### **Running Full Test Suite**
+
+```bash
+# Run complete integration test
+gh workflow run k8s-integration-test.yml
+```
+
+## 🔍 Troubleshooting
+
+### **Common Issues**
+
+1. **Kustomize Version Issues**
+
+   - Check `shared-config.yml` for version compatibility
+   - Update version in workflow inputs if needed
+
+2. **Kind Cluster Issues**
+
+   - Verify Docker is running
+   - Check available disk space
+   - Review kind configuration in workflow
+
+3. **API Test Failures**
+   - Check pod logs for initialization issues
+   - Verify model downloads completed
+   - Review API endpoint responses
+
+### **Debug Commands**
+
+```bash
+# Check workflow status
+gh run list --workflow=k8s-integration-test.yml
+
+# View specific run logs
+gh run view <run-id> --log
+
+# Download artifacts
+gh run download <run-id>
+```
