From 3bbcc2ab30c4654cad64a300152b4fb8a2de944c Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 5 Mar 2026 19:58:00 +0000 Subject: [PATCH 1/3] Add Kubernetes manifests and CI workflows for de.NBI migration Decompose the monolithic Docker container into Kubernetes workloads: - Streamlit Deployment with health probes and session affinity - Redis Deployment + Service for job queue - RQ Worker Deployment for background workflows - CronJob for workspace cleanup - Ingress with WebSocket support and cookie-based sticky sessions - Shared PVC (ReadWriteMany) for workspace data - ConfigMap for runtime configuration (replaces build-time settings) - Kustomize base + template-app overlay for multi-app deployment Code changes: - Remove unsafe enableCORS=false and enableXsrfProtection=false from config.toml - Make workspace path configurable via WORKSPACES_DIR env var in clean-up-workspaces.py CI/CD: - Add build-and-push-image.yml to push Docker images to ghcr.io - Add k8s-manifests-ci.yml for manifest validation and kind integration tests https://claude.ai/code/session_01RNJ3dVjV1VTHcC9ugE3FQJ --- .github/workflows/build-and-push-image.yml | 49 ++++++++++++ .github/workflows/k8s-manifests-ci.yml | 80 ++++++++++++++++++++ .streamlit/config.toml | 2 -
