Groundwork for foaf-protocol's leg of the fleet walk (rheos/growoperative-api#55). The other four apps are done — foaf-auth, railsbackend and onloan-api are all on Rails 8.1.4 / Ruby 3.4.11 in production, orchardly-rails is merged.

Why this comes first

foaf-protocol had no deploy workflow — and did not need one to deploy. Coolify has a per-app auto deploy on git push setting, invisible from this repo, and it was ON for all three tiers. Every merge to main rebuilt api.foaf.io — the ledger every FOAF app posts transfers through — immediately.

Auto-deploy is now off for prod, demo and beta (verified by read-back), so this workflow is the only way any tier deploys.

Tier Host Trigger
prod api.foaf.io manual dispatch + confirm=deploy-prod-protocol
demo dpi.foaf.io automatic, after CI passes on main
beta bpi.foaf.io manual dispatch

Same design as rheos/growoperative-api#85 and rheos/onloan-api#14. This is the last of the four gates in the fleet; orchardly-rails needs none, as it is not deployed anywhere.

Summary by CodeRabbit

  • Chores
    • Automated demo deployments after successful CI runs on the main branch.
    • Added manual deployment options for demo, beta, and production. Production deployments require an explicit confirmation.
    • Deployment status is monitored, with failures and timeouts reported.

foaf-protocol had no deploy workflow. It did not need one to deploy,
which was the problem: Coolify's own per-app "auto deploy on git push"
setting was ON for all three tiers, so every merge to main rebuilt
api.foaf.io - the ledger every FOAF app posts transfers through -
immediately. Nothing in this repo revealed that. Auto-deploy is now off
for prod, demo and beta, so this workflow is the only deploy path.

Demo deploys on workflow_run after CI reports success on main, not on
push, because a push trigger deploys red commits.

Talks to the Coolify API directly over HTTPS at coolify.rheo.ca rather
than tunnelling SSH, so it needs one secret and no key material on the
runner.

Prod requires confirm=deploy-prod-protocol.

Last of the four gates in the fleet (foaf-auth, railsbackend#85,
onloan-api#14, this one). orchardly-rails needs none - it is not
deployed anywhere.

📝 Walkthrough

Walkthrough

Adds a GitHub Actions workflow that deploys Coolify apps for demo, beta, and production. Successful CI runs on main deploy demo. Manual dispatch selects a tier, and production requires a specific confirmation. The workflow polls deployment status and fails on errors or timeout.

Changes

Coolify deployment

Layer / File(s) Summary
Deployment triggers and coordination
.github/workflows/deploy.yml
Defines successful CI and manual dispatch triggers. Groups deployments by tier and prevents cancellation of in-progress runs.
Tier resolution and production confirmation
.github/workflows/deploy.yml
Maps the selected tier to a Coolify UUID. CI-triggered deployments default to demo. Production dispatch requires the exact deploy-prod-protocol confirmation.
Coolify deployment and status polling
.github/workflows/deploy.yml
Starts deployment through the Coolify API and polls up to 90 times at 10-second intervals. Fails on API or parsing errors, failed or cancelled status, or timeout.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Merge Risk: 🟡 Moderate · up to c8789

This workflow becomes the only deployment path for demo, beta, and production. As written, demo can be deployed from a pull-request CI run or from a newer commit that has not passed CI. A user with write access can also bypass the production confirmation through the confirm input. These are small workflow edits and should be fixed before relying on this as the deployment gate.

Security Architecture Review

Security architecture risk: 🟠 High · up to c8789

The new deployment workflow contains a verified command-injection path in its production confirmation check. That path can undermine the intended production guard and may expose deployment authority. The actual reach of the shared deployment credential and external approval controls remains unverified.

Retained concerns

  • High · security · observed: Manual confirmation is inserted into shell source before the production guard. The verified injection can defeat that workflow-local control; the following step can deploy the selected production UUID with a shared Coolify bearer token. Direct token access in the guard step is not shown.
  • Medium · security · inferred: Manual dispatch can select production without a successful CI run, and the workflow declares no environment approval or actor check beyond the confirmation string. Whether external repository policy sufficiently restricts dispatchers and production-secret use remains unresolved; this is not a verified authorization bypass.
  • Medium · reliability · inferred: A successful CI run authorizes a demo deployment, but Coolify is instructed to pull the latest main rather than that run's tested commit. If main advances before Coolify pulls, the deployment can contain a commit whose CI has not passed, weakening the new green-CI gate.
Security review details

Security Blast Radius

  • inferred — The workflow configures three tier UUIDs and uses one token-backed API path for them. Production is an identified ledger endpoint; the maximum scope of the token beyond these configured deployments is unknown.

Security Findings and Attack Paths

  • observed — Two retained security findings cover dispatch-input interpolation at the same shell guard. Attacker-controlled confirmation text reaches Bash syntax before the production check; the next step holds deployment authority. Exploitation requires a principal able to dispatch the workflow, whose permitted population is not evidenced.

Trust Boundaries and Controls

  • observed — The successful-CI condition constrains workflow-run deployments, not manual ones. Unknown tiers fail closed, but the manual production confirmation is an in-band string, not an actor or environment approval.

Resilience and Maintainability Implications

  • inferred — The asserted off-repository auto-deploy setting is essential to the production guard: if it is re-enabled, a push can deploy outside this workflow. Neither that setting nor external recovery behavior is represented as an enforceable repository control.

Hardening Proposals

  • proposed — Pass dispatch inputs as data rather than interpolating them into shell source, and enforce production authorization independently of the confirmation text.
  • proposed — Verify dispatcher and environment protections and the Coolify token's tier scope; bind automatic deployments to the successful CI commit and monitor the external auto-deploy setting for drift.

Require a push-triggered CI run for automatic demo deployment.

CI also runs for pull requests. A successful pull-request run whose head branch matches main can satisfy the branch filter and this success check, causing an unintended demo deployment. Require github.event.workflow_run.event == 'push' in this condition. GitHub identifies the triggering event in the workflow-run payload. (docs.github.com)

Inspection citation: inspection_0ee572725e2047a14d1b34261c49f97a

- **Who can trigger it:** A user needs **write access** to the repository to manually run a workflow through the Actions UI. [1]
- **Which workflow file runs:** The `workflow_dispatch` workflow must exist on the **default branch** for dispatch to be enabled. You can select another branch or ref to run against; GitHub’s docs say runs use the workflow version at the event’s associated ref. So the selected ref can determine the workflow file version used, but it does **not** remove the requirement that the workflow exist on the default branch to be dispatchable. [2][3]
- **Repository secrets:** Yes. A workflow run on a branch in the **same repository** can access repository secrets, subject to the secrets’ usual scope and any organization or environment policies. The documented restriction is for workflows triggered from a **fork**, where secrets other than `GITHUB_TOKEN` are not passed to the runner. [4]

Pass confirm through a step environment variable, not shell source.

workflow_dispatch requires write access, so this is not an unauthenticated critical issue. However, confirm still becomes Bash source and can bypass the production confirmation. The next step exposes COOLIFY_API_TOKEN as CT. This job has no environment: protection or workflow-local approval gate.

A user with write access can already push a branch containing a modified copy of this workflow and dispatch that ref. Same-repository branch runs can receive repository secrets. The remaining risk is the production-confirmation bypass and token exposure when branch or environment protections would otherwise restrict that dispatcher.

Deploy the commit that passed CI.

The API request asks Coolify to pull the latest main; it does not identify github.event.workflow_run.head_sha. If commit A passes CI and commit B reaches main before this request, Coolify can deploy B while B's CI is pending or failing. Bind the deployment to the tested SHA, or block deployment unless the commit Coolify will build has passed CI. (docs.github.com)
