# EXPOSE WEBSITE

`EXPOSE WEBSITE [location on runner] (path) (rewrite path)`

The `EXPOSE WEBSITE` instruction creates a persistent link to view a webserver
running at a specific port in the Layerfile. It's especially useful for sharing
changes with non-technical stakeholders or running manual QA/review.

Additionally, the `EXPOSE_WEBSITE_HOST` environment variable is available even
before `EXPOSE WEBSITE` if you need to "bake" the path to the exposed website
URL.

If the default 2 minute timeout is not sufficient for your application, use the
following pattern to wait until the server is ready:

### Examples

* Use `EXPOSE WEBSITE localhost:80` to expose the local webserver at port 80
* Combine `EXPOSE WEBSITE localhost:80 /api` with
  `EXPOSE WEBSITE localhost:3000 /` to route all requests that start with /api
  to port 80 in the runner, and all other requests to port 3000.
* Use `EXPOSE WEBSITE localhost:80 /cypress$SPLIT` after a `SPLIT 5` directive
  to make each split have a unique path (e.g., `z.cidemo.co/split1`)
