# edge-port-host-bound

Generated from the code · as of CLI 0.6.0

The CLI prints, for example:

```text
the edge routes to `web` port 3000, which compose publishes only on host address `127.0.0.1`, where the edge cannot reach it. Write `ports: ["3000:3000"]`
```

Fix it in: `docker-compose.yml`.

## Keys that raise it

- [`edge`](https://docs.omniarc.eu/reference/arc-yaml/edge.md)
- [`edge.port`](https://docs.omniarc.eu/reference/arc-yaml/edge.md#edge-port)

**Example: shop/docker-compose.yml**

```yaml
# A small shop: Postgres holds the products, customers and orders, and
# PostgREST serves them as a JSON API on port 3000.
