+# Refactor Helm Chart to Service-Specific Templates
+
+## Overview
+
+This PR refactors our Helm chart structure from a loop-based approach to service-specific templates. The primary goal is to improve readability, maintainability, and flexibility of our Kubernetes resource definitions.
+
+## Problem Statement
+
+The previous approach of looping over API services to generate Kubernetes resources created several challenges:
+
+1. **Poor Readability**: Templates contained complex nested conditionals and loops
+2. **Difficult Maintenance**: Changes to template structure affected all services
+3. **Limited Flexibility**: Assumed all services followed the same pattern
+4. **Debugging Challenges**: Hard to trace issues to specific services
+5. **Upgrade Complexity**: Difficult to update individual services independently
+
+## Changes Made
+
+1. **Service-Specific Directory Structure**:
+   - Created dedicated directories for each service (`raster`, `stac`, `vector`, `multidim`)
+   - Each service directory contains its own templates (`deployment.yaml`, `service.yaml`, `configmap.yaml`, `hpa.yaml`)
+
+2. **Common Helper Functions**:
+   - Created a minimal `_common.tpl` with focused helper functions:
+     - `eoapi.mountServiceSecrets` - For mounting service secrets
+     - `eoapi.commonEnvVars` - For common environment variables
+     - `eoapi.pgstacInitContainers` - For init containers that wait for pgstac jobs
+
+3. **Service-Specific Configuration**:
+   - Added ability to control ingress per service:
+     ```yaml
+     stac:
+       enabled: true
+       ingress:
+         enabled: false  # Disable ingress for STAC only
+     ```
+   - Supports use cases like stac-auth-proxy where STAC API needs internal-only access
+   - Maintains backward compatibility with existing configurations
+
+4. **Integration with Existing Helpers**:
+   - Used existing `eoapi.postgresqlEnv` helper for database environment variables
+   - Maintained compatibility with other system helpers
+
+5. **Documentation**:
+   - Added a comprehensive README.md in the services directory explaining the refactoring approach
+   - Documented the new directory structure and helper functions
+
+## Benefits
+
+1. **Improved Readability**: Service configurations are explicit and clearly visible
+2. **Better Maintainability**: Changes to one service don't affect others
+3. **Enhanced Flexibility**: 
+   - Each service can evolve independently
+   - Can enable/disable features per service (like ingress)
+4. **Easier Debugging**: Errors are isolated to specific service files
+5. **Safer Changes**: Template modifications can be tested on individual services
+6. **Reduced Cognitive Load**: Developers can understand one service at a time
+
+## Example Use Cases
+
+1. **STAC with Auth Proxy**:
+   ```yaml
+   # values.yaml
+   stac:
+     enabled: true
+     ingress:
+       enabled: false  # No external ingress for STAC
+   ```
+   This allows stac-auth-proxy to handle external access while STAC API remains internal.
+
+2. **Mixed Access Patterns**:
+   ```yaml
+   stac:
+     ingress:
+       enabled: false  # Internal only
+   raster:
+     ingress:
+       enabled: true   # External access
+   ```
+   Different services can have different access patterns.
+
+## Testing
+
+The refactored templates have been tested using:
+
+1. `helm template` validation to ensure proper YAML generation
+2. Installation testing in a development environment
+3. Verification that all services deploy and function correctly
+4. Running the updated test suite to ensure all tests pass
+5. Comparison of the generated resources with the previous approach to ensure no functional changes
+
+## Backward Compatibility
+
+This refactoring maintains full backward compatibility with existing values files and deployments. No changes to values.yaml structure were required, and the chart can be upgraded in-place without disruption.
+
+## Next Steps
+
+Future improvements could include:
+
+1. Further service-specific customizations (e.g., annotations, labels)
+2. Enhanced documentation of service-specific options
+3. Schema validation for service-specific values
+4. Additional common helpers as patterns emerge
+

+# Unified Ingress Configuration
+
+This document describes the unified ingress approach implemented in the eoAPI Helm chart.
+
+## Overview
+
+eoAPI now uses a consolidated, controller-agnostic ingress configuration. This approach:
+
+- Eliminates code duplication between different ingress controller implementations
+- Provides consistent behavior across controllers
+- Simplifies testing and maintainability
+- Removes artificial restrictions on using certain ingress controllers in specific environments
+- Makes it easier to add support for additional ingress controllers in the future
+
+## Configuration
+
+The ingress configuration has been streamlined and generalized in the `values.yaml` file:
+
+```yaml
+ingress:
+  # Unified ingress configuration for both nginx and traefik
+  enabled: true
+  # ingressClassName: "nginx" or "traefik"
+  className: "nginx"
+  # Path configuration
+  pathType: "Prefix"  # Can be "Prefix" or "ImplementationSpecific" based on controller
+  pathSuffix: ""      # Add a suffix to service paths (e.g. "(/|$)(.*)" for nginx regex)
+  rootPath: ""        # Root path for doc server
+  # Host configuration
+  host: ""
+  # Custom annotations to add to the ingress
+  annotations: {}
+  # TLS configuration
+  tls:
+    enabled: false
+    secretName: eoapi-tls
+    certManager: false
+    certManagerIssuer: letsencrypt-prod
+    certManagerEmail: ""
+```
+
+## Controller-Specific Configurations
+
+### NGINX Ingress Controller
+
+For NGINX, use the following configuration:
+
+```yaml
+ingress:
+  enabled: true
+  className: "nginx"
+  pathType: "Prefix"
+  annotations:
+    nginx.ingress.kubernetes.io/use-regex: "true"
+    nginx.ingress.kubernetes.io/enable-cors: "true"
+    nginx.ingress.kubernetes.io/enable-access-log: "true"
+```
+
+### Traefik Ingress Controller
+
+When using Traefik, the system automatically includes the Traefik middleware to strip prefixes (e.g., `/stac`, `/raster`) from requests before forwarding them to services. This is handled by the `traefik-middleware.yaml` template.
+
+For basic Traefik configuration:
+
+```yaml
+ingress:
+  enabled: true
+  className: "traefik"
+  pathType: "Prefix"
+  # When using TLS, setting host is required to avoid "No domain found" warnings
+  host: "example.domain.com"  # Required to work properly with TLS
+  annotations:
+    traefik.ingress.kubernetes.io/router.entrypoints: web
+```
+
+For Traefik with TLS:
+
+```yaml
+ingress:
+  enabled: true
+  className: "traefik"
+  pathType: "Prefix"
+  # Host is required when using TLS with Traefik
+  host: "example.domain.com"
+  annotations:
+    traefik.ingress.kubernetes.io/router.entrypoints: websecure
+  tls:
+    enabled: true
+    secretName: eoapi-tls
+```
+
+## Migration
+
+If you're migrating from a previous version, follow these guidelines:
+
+1. Update your values to use the new unified configuration
+2. Ensure your ingress controller-specific annotations are set correctly
+3. Set the appropriate `pathType` for your controller
+4. Test the configuration before deploying to production
+
+## Note for Traefik Users
+
+Traefik is now fully supported in all environments, including production. The previous restriction limiting Traefik to testing environments has been removed.
+
+## Document Server
+
+The document server implementation has also been unified. It now works with both NGINX and Traefik controllers using the same configuration.
