Implements unified Helm chart supporting both deployment modes: - persistent: Traditional PVC-based deployment (v1.x behavior) - dynamic: Serverless Knative with auto-scaling and dynamic routing ## Chart Changes - Chart.yaml: Bump to v2.0.0-dev with deployment mode support - values.yaml: Add deploymentMode field and dynamic configuration - All templates: Conditional rendering based on deploymentMode ## Dynamic Mode Templates - knative-service.yaml: Auto-scaling dev containers with repo routing - routing-proxy.yaml: GitHub repo extraction service - dynamic-ingress.yaml: Ingress with Authentik auth support ## Usage Examples ```bash # Traditional persistent mode (default) helm install mydev ./chart --set name=mydev --set githubRepo=... # Dynamic serverless mode helm install mydev ./chart -f values-dynamic.yaml \ --set name=mydev --set dynamic.ingress.host=devcontainer.example.com # Development builds helm install mydev ./chart --set deploymentMode=dynamic \ --set image.tag=2.0.0-dev --set dynamic.ingress.host=... ``` All existing persistent deployments remain compatible (deploymentMode defaults to "persistent").
