feat: Add Helm chart for Kubernetes deployment #49
Description
Feature Request
Summary
Add an official Helm chart to enable easy deployment of Repowise on Kubernetes clusters.
Motivation
Repowise currently supports Docker and docker-compose deployment, but many teams run production workloads on Kubernetes. A Helm chart would:
- Enable one-command deployment to any k8s cluster (
helm install repowise ./charts/repowise) - Provide configurable values for API keys, resource limits, persistence, and ingress
- Make it easy to manage upgrades and rollbacks
- Allow integration with existing k8s tooling (ArgoCD, Flux, etc.)
Proposed Implementation
- Add a
charts/repowise/directory with a standard Helm chart structure - Include templates for: Deployment, Service, PVC (for SQLite + indexed data at
/data), Ingress, Secret, ServiceAccount - Configurable values for:
- LLM provider API keys (Anthropic, OpenAI, Gemini)
- Embedder selection (
mock,openai, etc.) - Resource requests/limits
- Persistence (storage class, size)
- Ingress (host, TLS, annotations)
- Backend/frontend ports
- Probes pointing at the API health endpoint
- Documentation in
charts/repowise/README.md
Context
The existing docker/Dockerfile and docker-compose.yml provide the container foundation. The Helm chart would build on top of the same image, mapping the same env vars and volume mounts into k8s-native resources.
