Coolify

Coolify deployments are detected via a webhook you configure in Coolify's notification settings. Results are posted as GitHub PR comments.

Setup

1. Go to Project → Settings → CI/CD and select Coolify.
2. Click Add Webhook and copy the generated URL.
3. In Coolify: Notifications → Webhook - paste the URL and enable deployment events.

TesterArmy uses pull_request_id from the Coolify payload to identify the PR.

Docker Compose workaround

Coolify has a known issue where Docker Compose deployments don't send the preview URL. Other build packs (Nixpacks, Dockerfile, Static) work out of the box.

Workaround: set a Preview URL pattern when creating the webhook:

https://{{pr_number}}.myapp.com

TesterArmy substitutes the PR number from the payload to build the URL.

Troubleshooting

Missing deployment URL

Webhook payload does not contain a deployment URL

• Docker Compose - configure a Preview URL pattern (see above).
• No domain configured - your app needs a domain set in Coolify.

No PR comment appears

1. GitHub App not connected - verify installation in Project Settings.
2. Missing PR number - Coolify only sends pull_request_id for preview deployments, not production.
3. Permissions - the GitHub App needs Pull requests: Read & Write.
