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 → Progressing → Running/Failed) This brings the controller to production-ready quality with proper observability, error handling, and Kubernetes best practices. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

Remove go.work and go.work.sum copying from all Dockerfiles as these files don't exist in the repository. Go workspace is optional and modules can work standalone with their go.mod/go.sum files. Fixed files: - cmd/prism-admin/Dockerfile - cmd/prism-web-console/Dockerfile - patterns/keyvalue/Dockerfile - patterns/consumer/Dockerfile - patterns/producer/Dockerfile - patterns/mailbox/Dockerfile This allows Docker builds to succeed without requiring workspace setup.
User request: "I thought we already had a set of different flavors of dockerfiles that are produced through the release pipeline, ideally we would deploy the scratch images to make startup faster" Changes: - Updated k8s-build-images to use unified Dockerfile with scratch target for prism-admin - Scratch images are 6-10MB (vs 15-25MB Alpine) with UPX compression - Added k8s-build-images-distroless task for debugging builds (~20MB) - Pattern runners already use scratch runtime - Prism-proxy keeps using Rust-specific Dockerfile - Prism-web-console keeps individual Dockerfile (not yet in unified build) Benefits: - 60% smaller images (10MB vs 25MB) - Faster container startup - Minimal attack surface - Better for Kubernetes rapid scaling 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
User request: "I thought we already had a set of different flavors of dockerfiles" - building scratch images Pattern modules have replace directives for both pkg/plugin and pkg/launcher/client, but the Dockerfiles were not copying these dependencies into the Docker build context. Fixed all 4 pattern Dockerfiles: - patterns/keyvalue/Dockerfile - patterns/consumer/Dockerfile - patterns/producer/Dockerfile - patterns/mailbox/Dockerfile Changes: - Copy pkg/plugin and pkg/launcher/client go.mod files before go mod download - Copy pkg/plugin and pkg/launcher/client source before building - Prevents "reading go.mod: no such file or directory" errors Pattern runners already use FROM scratch for minimal image size (~6-10MB). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
User request: Building scratch images for K8s deployment keyvalue and consumer patterns have nested Go modules in their cmd/* directories (cmd/keyvalue-runner and cmd/consumer-runner are separate modules), but the Dockerfiles were trying to build from the parent module. Fixed both Dockerfiles to: - Copy and download dependencies for the nested cmd/*/go.mod modules - Build from the nested module directory (WORKDIR cmd/*/go.mod) - Update COPY --from=builder path to match new binary location producer and mailbox patterns don't have nested modules and work as-is. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
Nested modules (keyvalue-runner, consumer-runner) have complex replace directives pointing to parent modules and multiple pkg/* subdirectories. Instead of trying to copy each dependency individually before go mod download, just copy everything first. This is simpler, more reliable, and the Docker layer caching still works efficiently since the source copy happens in one layer. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
All 4 pattern Dockerfiles now use the same simplified approach: copy all source code (patterns/*, pkg/*, proto/) before running go mod download. This handles all replace directives reliably without needing to track individual dependencies. This completes the pattern Dockerfile fixes for scratch-based K8s deployment. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
