fix(worker): give the worker a real health endpoint (#10987) The image bakes in a single HEALTHCHECK that curls http://localhost:8080/readyz, but the same image also runs `local-ai worker`, which serves HTTP on the gRPC base port minus one and never binds 8080. Every worker container was therefore permanently `unhealthy` (43 consecutive failures observed on a production node), which is worse than having no healthcheck: a genuinely broken worker and a perfectly good one both report `unhealthy`, so the signal carries no information and orchestration that keys on it misbehaves. The worker already served /readyz on that port via the file-transfer server, but as a constant 200 — it only proved the listener was bound, which is precisely the failure mode at issue. Readiness now tracks the live NATS connection: all of a worker's actual work (backend lifecycle events, inference dispatch, file staging) arrives over NATS, so a worker whose link is dead is up and useless. Registration is already implied, since the server only starts after registration succeeds. This reports something the controller cannot already see. The node registry's status/last_heartbeat is fed by an HTTP heartbeat to the frontend, a different network path from NATS — a worker can keep heartbeating while its NATS connection is dead and still look healthy in the registry. /healthz stays a constant 200: liveness must not follow readiness, or a NATS blip becomes a cluster-wide restart storm. The HEALTHCHECK is now a script that derives its endpoint from the mode the container is actually running plus the env vars that configure the bind address, so a frontend moved off 8080 with LOCALAI_ADDRESS (broken the same way) and a worker on a non-default base port are both probed correctly. Modes with no HTTP surface (agent-worker, one-shot commands) report healthy rather than false-unhealthy. HEALTHCHECK_ENDPOINT remains as an explicit override, so the workaround shipped in docker-compose.distributed.yaml keeps working; both overrides in that file are now unnecessary and have been removed. Also fixes the latent --start-period gap. Since #10949 a frontend's startup preload materializes HuggingFace artifacts before the HTTP server binds (31 GB observed on a live cluster), so a healthy replica can legitimately fail probes for a long time. --start-period is Docker's knob for exactly this: failures inside it leave the container `starting` instead of burning retries, and it ends early on the first success, so a generous 60m costs a fast-starting container nothing. --timeout drops from 10m to 10s — it is a per-probe deadline, and a localhost curl that has not answered in 10s is itself the fault being detected.

If you want to do SCSS edits and want to publish these, you need to install PostCSS
npm install
Running the website locally
Building and running the site locally requires a recent extended version of Hugo.
You can find out more about how to install Hugo for your environment in our
Getting started guide.
Once you've made your working copy of the site repo, from the repo root folder, run:
hugo server
Running a container locally
You can run docsy-example inside a Docker
container, the container runs with a volume bound to the docsy-example
folder. This approach doesn't require you to install any dependencies other
than Docker Desktop on
Windows and Mac, and Docker Compose
on Linux.
-
Build the docker image
docker-compose build -
Run the built image
docker-compose upNOTE: You can run both commands at once with
docker-compose up --build. -
Verify that the service is working.
Open your web browser and type
http://localhost:1313in your navigation bar, This opens a local instance of the docsy-example homepage. You can now make changes to the docsy example and those changes will immediately show up in your browser after you save.
Cleanup
To stop Docker Compose, on your terminal window, press Ctrl + C.
To remove the produced images run:
docker-compose rm
For more information see the Docker Compose documentation.
Troubleshooting
As you run the website locally, you may run into the following error:
➜ hugo server
INFO 2021/01/21 21:07:55 Using config file:
Building sites … INFO 2021/01/21 21:07:55 syncing static files to /

This error occurs if you have not installed the extended version of Hugo. See this section of the user guide for instructions on how to install Hugo.
Or you may encounter the following error:
➜ hugo server
Error: failed to download modules: binary with name "go" not found
This error occurs if you have not installed the go programming language on your system.
See this section of the user guide for instructions on how to install go.
