From 1449b2fa02377ce2db1390825e81f50a56aee15a Mon Sep 17 00:00:00 2001 From: Nikolai Emil Damm Date: Sat, 30 May 2026 01:12:27 +0200 Subject: [PATCH 1/5] feat: scaffold gitops tenant plumbing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Initial content for the GitOps tenant template: framework-agnostic, stack-neutral CI/CD plumbing for apps that run on the devantler-tech platform. Template-owned (kept in sync across tenants): - .github/workflows/cd.yaml — calls publish-app.yaml on v* tags (build, digest-pin, push + cosign-sign the manifests OCI artifact) - .github/workflows/release.yaml — semantic-release on main - .github/workflows/template-sync.yaml — weekly template-sync PR - AGENTS.md / CLAUDE.md — shared tenant conventions Scaffolding (tenant-owned; listed in each tenant's .templatesyncignore): example ci.yaml, dependabot baseline (actions + docker), .releaserc, Dockerfile, .sops.yaml, .gitignore, and a deploy/ skeleton (Deployment, Service, HTTPRoute, optional CNPG Cluster, example secret). cd.yaml and release.yaml are self-guarded so the template repo itself stays inert; they run only in tenants created from it. template-sync.yaml is pinned to the commit that introduces the reusable workflow (devantler-tech/reusable-workflows#261) and must be re-pinned to the released tag once that PR ships.
