# oz0 region name

> Give the unnamed region a name, for a cluster that starts to use regions: every tenant and node that is in no region moves to \<region> at once.

For: Operators and developers looking up a command.

Give the unnamed region a name, for a cluster that starts to use regions: every tenant and node that is in no region moves to \<region> at once. Start the edges with --region \<region> too, before or after: while the names differ, those tenants' work waits (Temporal keeps it; nothing is lost). Refused when tenants are pinned to that name already, and while a region move drains. Takes a cluster admin and --reason (or $OZ0_REASON).

Naming the region pins its tenants, and a pinned tenant whose data rules name no region may call only model providers in its region: a provider in another region, or one whose record names no region, is refused from then on, in running jobs too. Run with --dry-run first: it lists, per tenant, the providers and aliases that would be refused, and changes nothing.

Then set the tenants' rules (oz0 model rules --tenant \<t> --region \<regions>) or say where a provider runs (oz0 provider set \<id> --region \<region>) before you name the region.

## Usage

```bash
oz0 region name <region> [flags]
```
