CI CD Delivery

CI/CD Delivery

Overview

Meaningfy's deploy architecture is decoupled across three repos. This skill standardises the application-repo side of Continuous Delivery — the only side teams own day to day — and documents the contract to the two infrastructure repos without restating their runbooks.

It carries the delivery contract (how an app repo asks for a deploy and ships a release), a reusable-mechanism pointer + illustrative template, and a release/image standard. It owns CD only. Everything CI — build, unit/integration tests, lint, coverage, architecture guardrails, docs publish — is owned by project-setup. The two never overlap.

C1 — review with DevOps before adoption. The §6 decisions below are DevOps's to ratify. Do not contradict cloud-infrastructure / infrastructure-stacks runbooks, Vaultwarden, or the bastion procedure — treat them as the authoritative boundary. C2 — never put secrets in the repo or this skill. Every template carries placeholders only.

The three-repo model

Full detail in references/delivery-model.md. The mental model:

Routine deploys use rsync, not git-pull and not interactive SSH. The deploy workflow is the single auditable place where .env is assembled and the stack is brought up.

The secrets model

Full flow, rotation, and break-glass in references/secrets-model.md. The invariants:

• Secrets never live in the repo (C2) — not in code, not in this skill, not in committed files.
• Vaultwarden is the source of truth. GitHub Secrets are the deployment copy of those values, scoped to the repo/environment that deploys.
• The deploy workflow is the only place .env is assembled (from GitHub Secrets) and rsync'd to the VM. Explicit, auditable, no git-pull, no secret-bearing files in the repo.
• Rotation: rotate in Vaultwarden → update the matching GitHub Secret → re-trigger the deploy.
• Break-glass (bastion / SSH) is owned by the DevOps runbook — referenced, never duplicated here.

The application-repo CD standard

This is what the skill prescribes for the app-repo side. Three parts: the trigger contract, the reusable mechanism, and the release/image standard.

1. Deploy-trigger contract (R3)

Today three divergent patterns exist across repos (push-on-path to shared stacks; an in-repo self-hosted runner; cross-repo workflow_dispatch). One standard, the rest are legacy-to-migrate.

• Recommended default (pending DevOps §6 ratification): an app repo triggers a deploy by a cross-repo workflow_dispatch / repository_dispatch into infrastructure-stacks, or by consuming the devops-toolkit reusable workflow. It does not carry its own bespoke deploy glue.
• Legacy to migrate: push-on-path against shared stacks, and the in-repo self-hosted runner. Both are named in references/delivery-model.md with their migration target.

2. Reusable deploy mechanism (R4)

The SSH/bastion/rsync/.env block is currently copy-pasted ~7× across repos. A devops-toolkit reusable op-delivery.yml already exists and ted-rdf-conversion-pipeline uses it — proof the pattern works.

• The single runnable source of truth is the devops-toolkit reusable workflow. App repos uses: it. Skillery never hosts a second runnable copy — that is exactly the duplication this skill exists to kill.
• The template in references/deploy-workflow-template.md is illustrative / teaching only: it shows the shape of the caller and how inputs/secrets map, and points at the canonical devops-toolkit source.

3. Release + image standard (R5)

Today no repo pushes a versioned image to a registry — all build on the VM from source, so there is no pinned, rollback-able artifact. The standard (template in references/release-image-template.md):

• Build a Docker image, tag by semver + git sha, push to a registry (recommended GHCR).
• Version source = git tag / GitHub release → image tag → optional changelog.
• Stacks then pull a pinned versioned image instead of building on the VM — giving repeatable, rollback-able deploys.

§6 — DevOps decisions to confirm (NOT yet ratified)

These are recommendations to present to DevOps, not settled policy. Mark them as such wherever you act on them.

1. Deploy-trigger standard — recommended: the devops-toolkit reusable workflow (already exists; removes the duplication centrally).
2. Registry-pushed versioned images — recommended: adopt GHCR + semver/sha. Biggest current gap; it is what makes deploys rollback-able.
3. Home of the reusable deploy mechanism — recommended: centralise in devops-toolkit; all repos uses: it.

Until DevOps ratifies these, treat the recommendations as proposals: a deployable repo gets a clearly-marked TODO stub plus the boundary docs, not a rendered runnable deploy workflow.

Migration runbook

A concrete per-repo PR recipe lives in references/migration-runbook.md: replace the inline ~7× rsync/bastion block with uses: the reusable mechanism, map inputs/secrets, verify. A team can execute it without re-deriving the pattern.

Projection seam (→ project-setup, EPIC-09)

project-setup scaffolds these CD/release templates only for a deployable project, and only renders the chosen template after DevOps ratifies §6. Until then a deployable repo receives a clearly-marked TODO stub plus the boundary docs — never a half-guessed runnable deploy workflow. This skill owns the content of those templates; project-setup owns when and into what repo they are projected.

Boundary & Related Skills

Owns: the application-repo CD side — the deploy-trigger contract, the reusable-mechanism pointer + illustrative template, the release/image standard (semver + git sha → GHCR), and the per-repo migration runbook. Delegates: CI (build, test, lint, coverage, architecture guardrails, docs publish) → project-setup; code layering / structure → cosmic-python. Documents-only (authoritative boundary, never automated or duplicated here): cloud-infrastructure (Terraform/Ansible), infrastructure-stacks (Compose stacks + deploy Actions), Vaultwarden (secret source of truth), and the bastion/SSH break-glass procedure. Related: project-setup, cosmic-python, meaningfy-release — the release lifecycle (versioning, release notes, PyPI publish, the release/hotfix runbook); it cites this skill for the GHCR image path and does not restate it.
