• Added blueprints/nodelink/template.toml defining domain routing, generated server password, and configurable logging/local-source/metrics env vars, plus a README mount.
• Added blueprints/nodelink/nodelink.svg and a corresponding meta.json entry for template indexing.

Automated template check 🤖

This PR's template was imported into a test Dokploy instance (using the docker-compose.yml + template.toml from the PR head) and deployed, and its configured domains were then checked over HTTP.

Result: ❌ some issues need attention

nodelink

• Deploy: done (25s)
• Domain checks:
  • nodelink:2333 → HTTP 404 ❌
• Container states at failure time: nodelink-1: running
• Issues:
  • domain check failed for service nodelink:2333 (path /): kept returning HTTP 404 for 3 minutes after the deploy finished

The test service is removed automatically after verification. Happy to re-test once the PR is updated.

Pushed a fix for the sustained 404 on the assigned domain (ef8071e).

Root cause: NodeLink requires the Authorization header on every API route, including /version. The compose healthcheck fetched /version without credentials, so it always got a 401 and the container stayed permanently unhealthy. Traefik skips unhealthy containers, which is why the domain kept returning 404 page not found even though the deploy finished and the container was running.

Fix: pass the container's NODELINK_SERVER_PASSWORD as the Authorization header in the healthcheck fetch (one-line change in docker-compose.yml).

Verified on a live Dokploy deployment: the container reaches healthy, the domain routes to the server (401 Unauthorized on / without credentials, as expected for a Lavalink-compatible server), and /version returns 3.8.0 with the generated password.
