📝 WalkthroughWalkthroughThis PR adds label-gated pull-request previews with isolated Compose stacks, signed Coolify deployment, exact-commit image verification, forced SSH cleanup, scheduled reconciliation, stack validation, tests, documentation, and migration guidance. ChangesPreview deployment lifecycle
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to This PR adds label-triggered preview deployments using commit-built images in isolated stacks. The current deployment path can verify one image and later pull a different mutable tag, while several safety checks can be bypassed or skipped; an incorrect image or unsafe stack could therefore reach a preview. Cleanup and operator documentation gaps add bounded deployment risk, so merge should wait for these issues to be fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

Qualify the label instruction by the deployment setup state.
Preview deployments remain disabled until the repository variables, secrets, Coolify application, and cleanup key are configured. This paragraph says that adding preview deploys without that condition. State that the feature must be enabled first.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
The build-context check does not constrain the webapp service.
For webapp, expectedBuild.context is ".". expectedBuild.context.replace(/^\.$/, "") returns "", and build.context.endsWith("") is always true. The context check therefore passes for any string. The dockerfile check also passes when build.dockerfile is absent, because the condition requires typeof build.dockerfile === "string". A webapp build that points at another context, or that omits dockerfile, renders no violation even though the comment on Line 28 states these are "the only build inputs they may use".
Compare the repository-relative context instead of a suffix, and require the dockerfile field to be present.
🛠️ Proposed fix
if (expectedBuild !== undefined) {
const build = isRecord(service.build) ? service.build : {};
const dockerfile = expectedBuild.dockerfile ?? "Dockerfile";
+ // `docker compose config` renders an absolute context, so compare the trailing segment
+ // against the declared one; "." means the repository root itself.
+ const contextMatches =
+ typeof build.context === "string" &&
+ (expectedBuild.context === "."
+ ? !build.context.includes("/docker/") && !build.context.includes("/webapp/")
+ : build.context.endsWith(`/${expectedBuild.context}`));
if (
- typeof build.context !== "string" ||
- !build.context.endsWith(expectedBuild.context.replace(/^\.$/, "")) ||
- (typeof build.dockerfile === "string" && !build.dockerfile.endsWith(dockerfile))
+ !contextMatches ||
+ typeof build.dockerfile !== "string" ||
+ !build.dockerfile.endsWith(dockerfile)
) {
violations.push(`${name} no longer builds from ${expectedBuild.context}/${dockerfile}`);
}
}Note that scripts/check-preview-stack.test.ts builds postgres without a dockerfile field, so the fixture needs the rendered dockerfile value once this check requires it.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
lastTransportError is never cleared, so a timeout can report a stale cause.
lastTransportError is module state and only ever assigned on failure. If one early fetch fails and later requests succeed, waitForDeployment still ends with Gave up reaching Coolify: <old error> when it times out while the deployment stays in_progress. The test at scripts/coolify-preview.test.ts Lines 426-469 shows this exact sequence of a transport failure followed by successful reads. Operators then chase a network problem that already recovered.
Clear the value after a successful fetch.

🧩 Analysis chain
🌐 Web query:
Node.js fs.writeFileSync mode option ignored existing file permissions
💡 Result:
The mode option in Node.js fs.writeFileSync (and fs.writeFile) is not ignored, but its application is specifically limited to scenarios where a new file is created [1][2][3]. When fs.writeFileSync is called on an existing file, it does not modify the file's existing permissions; it preserves the current mode [4][5]. This behavior aligns with the underlying POSIX open system call, which only applies the specified mode when a file is created [4][5]. If you need to change the permissions of an existing file, you must use fs.chmodSync or fs.chmod explicitly after the write operation [5][6]. Additionally, note that even when the mode option is used to create a new file, the final permissions are subject to the process's umask [6]. This means the resulting file mode is typically the bitwise AND of the requested mode and the complement of the current umask (mode & ~umask) [6].

Protect SSH credential files on reused runners
writeFileSync applies mode only when it creates a file. If either path already exists, the write preserves its permissions and can expose the private key on a reused self-hosted runner.
Use unique, exclusively created per-invocation paths, and remove only files owned by that invocation. Do not use fixed flag: "wx" paths with the current cleanup logic because a concurrent invocation could remove the first invocation’s files.

The comparison passes when neither file yields a pin.
natsPin returns undefined when the regex does not match. The regex needs the exact literal image: nats:, so a quoted value, a renamed service, or a registry prefix makes it miss. If the pattern stops matching in both files, referenceNats !== previewNats is false and the guard reports nothing. The check then protects nothing, and the message would also read "pins undefined but ... pins undefined" if only one side matched.
Require a pin from each file.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
The not found match turns a real render failure into a silent skip.
spawnSync sets status to null when the docker binary is missing, and line 133 already covers that case. The added /not found/i test is applied to arbitrary Compose stderr. Compose reports many genuine errors with that wording, for example a missing service, a missing file, or a missing image reference. Any such failure returns undefined, the caller prints "skipped, no Docker daemon to render it with", and the sandbox gate passes without asserting anything.
Match only the daemon-connection message, and let every other non-zero exit throw.

The redirect: "manual" assertion cannot fail this test.
The health probe in waitForDeployment calls attemptFetch, which catches every throw from dependencies.fetch and retries. If line 389 throws, attemptFetch swallows it, the loop retries, call 6 returns HTTP 200, and the test still reaches state === "success" with calls === 6. A regression that drops redirect: "manual" therefore passes.
Record the observed value and assert it after waitForDeployment returns.

Add the `preview` label to a pull request and its current commit deploys once CI passes; every later green head follows automatically. Removing the label, closing the pull request, or converting it to draft tears the stack down and frees its slot. Previews run signed, commit-addressed CI images with their own database, broker and credentials — no staging Docker socket, network or data. Forks never deploy, and a head that introduces changes to the deployment workflows or the preview Compose file is refused until that change merges.

Teardown now ends at the signed close event Coolify acknowledges, and the nightly reconcile re-sends it for anything the events missed. The SSH channel it replaces cost a standing private key, a root-owned binary installed out of band on the deployment host, and a job to detect the two drifting — to prove a failure nobody has observed. If a preview stack is ever seen outliving its pull request, the reconcile workflow is where that check belongs.

halt does not emit the opted_out output the deploy workflow reads.
.github/workflows/deploy-preview.yml Line 188 gates the failure comment on steps.recheck.outputs.opted_out != 'true'. halt sets only proceed, so opted_out is always empty and the guard never suppresses the comment. An author who removes the preview label during a deployment, or pushes a newer commit, then receives a ❌ "App Preview" comment for an intentional stop.
Set the output in halt so the workflow guard works.

Bound each Docker invocation before the workflow deadline.
spawnSync("docker", [...arguments_]) has no timeout. A stalled Docker daemon can block cleanup until the eight-minute workflow ends, preventing resource verification and tombstone creation. Set a timeout within the cleanup budget and report timeout failures explicitly.

The compose validation job exports COMPOSE_ENV_FILES for the self-hosted stack, and the preview render inherited it — pointing Compose at a .env the repository root does not have. The preview stack ships no env file at all, so drop the variable for that render.

Restores what #1455 built and #1557 dropped: a preview starts from a pg_dump of staging's database and consumes staging's JetStream, so it is worth looking at rather than an empty install. The seed loader runs before the application server may boot. It cancels queued work, disables every review trigger, and drops the instance identity, then verifies that against the database and refuses to mark the preview seeded if the policy did not take — a preview that cannot be silenced stays down. It holds the Docker socket read-only because pg_dump and psql run inside the two database containers; check-preview-stack.ts now refuses that mount on any other service, and refuses it writable on this one. The local broker is gone. The application server joins staging's shared-network for its broker, with a durable named per deploy so previews never compete for one consumer, and a 72h inactivity window because a preview is deleted rather than shut down. staging-shared is external and named, which the sandbox check now distinguishes from the project-scoped networks every preview would share.

Description
Add the
previewlabel to a pull request and get a running copy of your branch on a URL. Everypush redeploys it, and it never waits for your tests to pass — a preview is most useful exactly
when they don't. It disappears when you remove the label, close the pull request, or convert it to
draft. No review, no command, no ceremony — you can label your own PR.
A preview runs the images CI published for your commit — the same artifacts staging and
production run, buildpack-built application server included. It waits for those images, which CI
builds in parallel with the tests, and never for the tests themselves: about half a minute for a
docs-only change where unchanged images are re-tagged, a few minutes when you touch the webapp or
the server.
That is the point. A preview assembled a second way could start cleanly where the released image
would not — which is exactly what a preview of a Spring Boot service exists to catch.
What is in a preview
A clean install: empty database, no seeded workspace, no synced GitHub data, no agent runs, no
inbound webhooks. Good for UI, routing, and migrations against an empty schema. Not the place to
check practice reviews or the leaderboard — those need staging.
Security
Pull-request code is untrusted, so the gates describe what may run, not who asked:
pull_requestworkflows here already receive repository secrets (cd-docs.ymldeploys withSURGE_TOKEN)reusable-docker-build.yml.github/workflows/**,.github/actions/**ordocker/preview/**is refused until that change merges — compared againstmain, so a stacked layer cannot inherit an edit from the layer belowscripts/check-preview-stack.tsfails CI if the Compose file ever gains asocket mount, a build stage, a published port, an external network, an unbounded memory limit, a
routable backend network, or a flipped integration switch.

a preview it fails to remove would leak silently. No such leak has been observed, and checking it
would mean a standing credential on the deployment host — so that is deliberately out of scope
here. Watch the host's container list for the first few weeks.

not a decision; it should move before this is announced widely.
approval re-checked against every commit; it was replaced because it required a fresh review after
every push, which inverts the purpose of a preview.
How to test
bun run format && bun run checkpasses on this branch, and the pull request CI run is the mergeauthority. Beyond that, CI covers this: the preview workflows cannot run until the repository
variables exist, so there is nothing to exercise before merge.
scripts/check-preview-stack.tsis the one new gate that runs on every pull request from now on —its tests assert that each sandbox escape it names is actually caught, rather than only that a good
file passes.
