From 8e01dad50fbbdf5aaa1268e300d7020c19f1f811 Mon Sep 17 00:00:00 2001 From: Jacob Repp Date: Wed, 22 Oct 2025 14:26:54 -0700 Subject: [PATCH 01/18] Implement PrismStack controller for full K8s deployment MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit User request: "create a new branch for deploying components to k8s - we are going to build on the prism-operator and setup a full local test loop with the docker local k8s we want to be able to deploy all the components into a prism namespace in k8s using the controller install CRDs bring up a proxy service layer, memory backed runners with auto scaling, admin plane and web-console service layer that connects to the admin plane, the whole deployment should be controlled by the prism-operator and the CRDs" Implemented complete PrismStack CRD and controller: - Added WebConsoleSpec to PrismStack types with full configuration - Implemented PrismStackReconciler with reconciliation for all components - Registered PrismStack controller in operator manager - Enabled PrismStack type registration in SchemeBuilder Controller reconciles: - Admin control plane (3 replicas with leader election) - Proxy data plane (configurable replicas with auto-scaling) - Web console (connects to admin endpoint) - Pattern runners (keyvalue, consumer, producer, mailbox with MemStore) Sample deployment: - config/samples/prismstack_local_complete.yaml - Full local stack manifest - Complete deployment with all components for Docker Desktop K8s - Memory-backed patterns for fast local testing - LoadBalancer service for web console access Documentation: - K8S_LOCAL_DEPLOYMENT.md - Comprehensive deployment guide - Quick start (5 minutes to running stack) - Scaling, configuration, observability setup - Troubleshooting and production considerations Next steps: - Build container images for all components (Dockerfile creation) - Add Task targets for k8s deployment automation - Test full deployment in Docker Desktop πŸ€– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- prism-operator/K8S_LOCAL_DEPLOYMENT.md | 489 ++++++++++++ .../api/v1alpha1/prismstack_types.go | 37 +- prism-operator/cmd/manager/main.go | 8 + .../samples/prismstack_local_complete.yaml | 139 ++++ .../controllers/prismstack_controller.go | 694 ++++++++++++++++++ 5 files changed, 1363 insertions(+), 4 deletions(-) create mode 100644 prism-operator/K8S_LOCAL_DEPLOYMENT.md create mode 100644 prism-operator/config/samples/prismstack_local_complete.yaml create mode 100644 prism-operator/controllers/prismstack_controller.go diff --git a/prism-operator/K8S_LOCAL_DEPLOYMENT.md b/prism-operator/K8S_LOCAL_DEPLOYMENT.md new file mode 100644 index 000000000..8aef186f0 --- /dev/null +++ b/prism-operator/K8S_LOCAL_DEPLOYMENT.md @@ -0,0 +1,489 @@ +# Prism Kubernetes Local Deployment Guide + +Complete guide for deploying full Prism stack to Docker Desktop Kubernetes. + +## Architecture + +This deployment creates a complete Prism system with: + +``` +β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” +β”‚ Kubernetes Cluster (prism-system) β”‚ +β”‚ β”‚ +β”‚ β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”‚ +β”‚ β”‚ Web Console │─────▢│ Admin Plane β”‚ β”‚ +β”‚ β”‚ (2 replicas) β”‚ β”‚ (3 replicas HA) β”‚ β”‚ +β”‚ β”‚ Port: 8000 β”‚ β”‚ Port: 8981 β”‚ β”‚ +β”‚ β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ β”‚ +β”‚ β”‚ β”‚ +β”‚ β–Ό β”‚ +β”‚ β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”‚ +β”‚ β”‚ Proxy Plane β”‚ β”‚ +β”‚ β”‚ (3 replicas) β”‚ β”‚ +β”‚ β”‚ Port: 8980 β”‚ β”‚ +β”‚ β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ β”‚ +β”‚ β”‚ β”‚ +β”‚ β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”Όβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”‚ +β”‚ β–Ό β–Ό β–Ό β”‚ +β”‚ β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”Œβ”€β”€β”€β”€β”€β” β”‚ +β”‚ β”‚ KeyValue β”‚ β”‚ Consumer β”‚ β”‚ ... β”‚ β”‚ +β”‚ β”‚ (MemStore) β”‚ β”‚ (MemStore) β”‚ β””β”€β”€β”€β”€β”€β”˜ β”‚ +β”‚ β”‚ 2 replicas β”‚ β”‚ 2 replicas β”‚ β”‚ +β”‚ β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ β”‚ +β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ +``` + +## Prerequisites + +1. **Docker Desktop** with Kubernetes enabled + ```bash + # Enable Kubernetes in Docker Desktop settings + # Preferences β†’ Kubernetes β†’ Enable Kubernetes + ``` + +2. **kubectl** configured for docker-desktop context + ```bash + kubectl config use-context docker-desktop + ``` + +3. **Go 1.21+** (for building operator) + ```bash + go version + ``` + +4. **Container images built** (or available from registry) + -

fe7dcde787f9d6d335450994524b69a9e9551f90 Mon Sep 17 00:00:00 2001 From: Jacob Repp Date: Wed, 22 Oct 2025 14:40:26 -0700 Subject: [PATCH 02/18] Polish PrismStack controller with production-ready best practices MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Applied comprehensive operator best practices to PrismStack controller: Enhanced Status Tracking: - Added detailed ComponentStatus for each component (admin, proxy, web-console, patterns) - Track replicas, available replicas, ready state, and messages - Added LastUpdateTime for monitoring - Component-specific conditions (AdminReady, ProxyReady, WebConsoleReady) Kubernetes Events: - Event recording for all significant operations - Success events for reconciliation completion - Warning events for failures with detailed messages - Lifecycle events (initializing, finalizer added/removed, deletion) Error Handling & Requeue Strategies: - Proper error wrapping with context - Transient error detection (conflicts, timeouts) - Smart requeue delays (30s short, 5m long) - Failed phase with condition updates on errors Observability & Logging: - Structured logging with key-value pairs - Log levels (V(1) for detailed logs) - Context-aware loggers per component - Operation-specific log messages Production Features: - Finalizers for proper cleanup - Spec validation before reconciliation - Event filtering predicate (only reconcile on spec/deletion changes) - Health probes (liveness, readiness) for all components - Owner references for cascading deletes - Helper functions for cleaner code (createOrUpdateDeployment, createOrUpdateService) Status Conditions: - Ready condition tracking overall stack health - Component-specific conditions for granular monitoring - Observed generation tracking - Phase transitions (Pending β†’ Progressing β†’ Running/Failed) This brings the controller to production-ready quality with proper observability, error handling, and Kubernetes best practices. πŸ€– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../api/v1alpha1/prismstack_types.go | 52 +- prism-operator/cmd/manager/main.go | 5 +-

charset=UTF-8 Content-Transfer-Encoding: 8bit User request: "continue" Added 18 Kubernetes tasks to Taskfile.yml for complete K8s deployment workflow: Image Management: - k8s-build-images: Build all 7 Docker images for Kubernetes deployment CRD Management: - k8s-generate-crds: Generate Kubernetes CRDs from operator types - k8s-install-crds: Install CRDs into Kubernetes cluster Deployment: - k8s-deploy-local: Deploy PrismStack to local Kubernetes (memstore backend) - k8s-deploy-postgres: Deploy with PostgreSQL backend and data locality - k8s-run-operator: Run operator locally for development Status & Monitoring: - k8s-status: Check deployment status (pods, services, deployments, events) - k8s-status-postgres: Check PostgreSQL backend deployment status - k8s-describe: Describe PrismStack resource in detail Logging: - k8s-logs: Tail logs from all Prism components - k8s-logs-admin: Tail logs from Admin control plane - k8s-logs-proxy: Tail logs from Proxy - k8s-logs-web-console: Tail logs from Web Console - k8s-logs-patterns: Tail logs from all Pattern runners Utilities: - k8s-port-forward-console: Port forward to Web Console (localhost:8000) Cleanup: - k8s-clean: Clean up Kubernetes deployment - k8s-clean-postgres: Clean up PostgreSQL backend deployment - k8s-clean-all: Clean up all resources including CRDs Updated K8S_DEPLOYMENT_STATUS.md: - Documented all 18 Kubernetes tasks with categories - Updated testing workflows with task commands - Added Quick Start guide for local memstore deployment - Added PostgreSQL with data locality deployment guide - Added development workflow examples Task automation enables: - One-command image building for all 7 components - Automated CRD generation and installation - Simple deployment with dependencies handled automatically - Comprehensive status checking and log viewing - Easy cleanup of all resources All tasks follow Task best practices with proper dependencies and clear output messages for user feedback. πŸ€– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- K8S_DEPLOYMENT_STATUS.md | 172 +++++++++++++++++++++------------------

go.mod: K8s client dependencies (client-go, controller-runtime) - helpers.go (390 lines): K8s testing utilities - TestContext with Kubernetes clients (clientset, runtime client) - Namespace lifecycle (create, delete with cleanup wait) - Wait functions for deployments, statefulsets, pods - Pod logs retrieval and printing - Service endpoint discovery - Component health checking - fixtures.go (180 lines): Test manifests and constants - PrismStackLocalManifest: Full stack with StatefulSet admin, patterns - PrismStackMinimalManifest: Minimal deployment for quick tests - Expected component/deployment/service helpers - k8s_test.go (490 lines): Comprehensive integration tests - TestPrismStackFullLifecycle: Complete end-to-end test - TestPrismStackMinimal: Quick deployment test - TestPrismStackReconciliation: Operator reconciliation tests - Operator lifecycle management (install CRDs, start/stop operator) Test workflow: 1. Install CRDs (generate with make manifests, kubectl apply) 2. Start operator in background (make run with context cancellation) 3. Create test namespace 4. Deploy PrismStack from YAML manifest 5. Wait for all components to be ready (admin, proxy, web-console, patterns) 6. Verify component health and PrismStack status 7. Run reconciliation tests (scaling, pod recreation) 8. Clean up (stop operator, delete namespace, uninstall CRDs) Added Taskfile.yml tasks: - test-integration-k8s: Run full K8s integration tests (30m timeout) - test-integration-k8s-short: Run quick tests only (10m timeout, -short flag) Features: - Full operator lifecycle as test fixture (not separate process) - Automatic CRD generation and installation - Background operator with log capture - Comprehensive wait functions with progress logging - Component health verification - Service discovery and endpoint testing - Reconciliation testing (scaling, self-healing) - Proper cleanup with finalizers Prerequisites for running tests: - Docker Desktop K8s or Minikube running - Docker images built (task k8s-build-images) - kubectl in PATH - ~30 minutes for full test suite Run with: task test-integration-k8s # Full test suite task test-integration-k8s-short # Quick tests only go test -v ./tests/integration/k8s # Direct go test πŸ€– Generated with [Claude

renumbering K8s deployment RFC to RFC-043 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit User request: "docs pr and other PR failures" Fixed documentation validation errors blocking PR #43: **Issue 1 - Duplicate RFC ID**: - Two RFCs both had id: rfc-019 - RFC-019-k8s-deployment-patterns-and-scaling.md (uppercase, newer) - rfc-019-plugin-sdk-authorization-layer.md (lowercase, older) **Resolution**: - Renumbered K8s deployment RFC from RFC-019 to RFC-043 (next available) - Renamed file to lowercase: rfc-043-k8s-deployment-patterns-and-scaling.md - Updated frontmatter: id, title, added author/created fields - Fixed unlabeled code fence (line 519) to use ```text - Updated reference in K8S_DEPLOYMENT_STATUS.md **Validation**: All 143 documents now pass validation βœ… This fixes the Docusaurus build failure: "The docs plugin found docs sharing the same id" πŸ€– Generated with [Claude
