From 37c705bf017acbd78e7b06ff2a16733ff7face9f Mon Sep 17 00:00:00 2001 From: Jess Sullivan Date: Wed, 11 Feb 2026 23:17:46 -0500 Subject: [PATCH 1/5] feat: CI/CD pipeline, containerized deployment to Civo K8s - Dockerfile: multi-stage Node 22 Alpine build with dumb-init - hooks.server.ts: COOP/COEP headers for Futhark WASM multicore - /api/health endpoint for K8s liveness/readiness probes - verify.yml: parallel 6-job CI matrix (typecheck, unit, futhark, theorem, e2e, build) - build-image.yml: Docker build + push to GHCR on master - deploy.yml: kubectl rollout to Civo cluster after image build - release.yml: semver tag automation with GitHub Releases - k8s/: namespace, deployment, service, ingress, DNS manifests -
