 `--locality` | If nodes were started with [locality]({% link {{ page.version.version }}/cockroach-start.md %}#locality) details, you can use the `--locality` flag here to filter the nodes included in the HAProxy config file, specifying the explicit locality tier(s) or a regular expression to match against. This is useful in cases where you want specific instances of HAProxy to route to specific nodes. See the [Generate an HAProxy configuration file](#generate-an-haproxy-config-file) example for more details.
