# Set the repository a tenant's images must sit in

PUT

/v1/system/tenants/{tenantId}/image-prefix

```sh
curl --request PUT \
  --url https://example.com/v1/system/tenants/2489E9AD-2EE2-8E00-8EC9-32D5F69181C0/image-prefix \
  --header 'Authorization: Bearer <token>' \
  --header 'Content-Type: application/json' \
  --data '{ "prefix": "example" }'
```

Each tenant may deploy only images at or under its own repository: `<host>/<path>`, matched on a path boundary, with no trailing slash. On a runtime serving many tenants, a tenant without one can’t register a deployment. Takes `system:tenants:image-prefix`, the key that binds the tenant’s slot; changing a prefix that’s already set takes the full system capability. A closing tenant is refused (`409 tenant-closing`).

## Authorizations

- **[bearerAuth](https://docs.kindgi.com/v0.1.8/reference/api.md#bearerauth)**

## Parameters

### Path Parameters

**tenantId**

required

string format: uuid

The tenant’s id.

### Header Parameters

**Idempotency-Key**

string

\>= 1 characters

Caller-supplied idempotency key, scoped to the caller: the same key from someone else in the tenant is their own request (from 0.1.5). Retries with the same key return the original response byte-identical (per `docs/API-ROUTE-CONVENTIONS.md` §3.1). A retry sent while the first request still runs is answered `409 idempotency-key-in-flight` with `Retry-After`, on a runtime whose store holds keys (from 0.1.5); retry after it, and you get the first request’s answer. An answer that carries a secret (a new API key or public run token, a session token, a generated signing secret) isn’t kept: a retry gets `409 idempotency-key-replay-withheld`, with the first request’s status and when it succeeded (from 0.1.5).
