# /sys/quotas/lease-count

The `/sys/quotas/lease-count` endpoint is used to create, edit and delete lease count quotas.

### Create or update a lease count quota

This endpoint is used to create a lease count quota with an identifier, `name`. A lease count quota must include a `max_leases` value with an optional `path` that can either be a namespace or mount, and can optionally include a path suffix following the mount to restrict more specific API paths.

Upon creating a lease count quota, it will be populated with the current count of leases from this path. If there are more leases present than the specified `max_leases`, this will cause the lease count to go over the specified `max_leases`.

The initial population process can cause a lot of work for Vault - and while creating one lease count quota is always fine, if you're planning to create — for example — thousands of lease count quotas for paths with millions of leases in an automated way, it is recommended to space out the creation requests.

| Method | Path                            |
| ------ | ------------------------------- |
| `POST` | `/sys/quotas/lease-count/:name` |

#### Parameters

* `name` `(string: "")` - The name of the quota.
* `path` `(string: "")` - Path of the mount or namespace to apply the quota. A blank path configures a global lease count quota. For example `namespace1/` adds a quota to a full namespace, `namespace1/auth/userpass` adds a quota to `userpass` in `namespace1`, and `namespace1/kv-v2/data/foo/bar` adds a quota to a specific secret on a K/V v2 mount in `namespace1`. A trailing glob (`*`) can also be added as part of the path after the mount to match paths that share the same prefix prior to the glob. `namespace1/kv-v2/data/foo/*` would match both `namespace1/kv-v2/data/foo/bar` and `namespace1/kv-v2/data/foo/baz`. Updating this field on an existing quota can have "moving" effects. For example, updating `namespace1` to `namespace1/auth/userpass` moves this quota from being a namespace quota to a namespace-specific mount quota. Non-global quotas are not inherited by child namespaces.
* `max_leases` `(int: 0)` - Maximum number of leases allowed by the quota rule.
* `role` `(string: "")` - If set on a quota where `path` is set to an auth mount with a concept of roles (such as `/auth/approle/`), this will make the quota restrict login requests to that mount that are made with the specified role. The request will fail if the auth mount does not have a concept of roles, or `path` is not an auth mount.
* `inheritable` `(bool: false)` - If set to `true` on a quota where `path` is set to a namespace, the same quota will be cumulatively applied to all child namespace. The `inheritable` parameter cannot be set to `true` if the `path` does not specify a namespace. Only the quotas associated with the root namespace are inheritable by default.

#### Sample payload

```json
{
  "path": "",
  "max_leases": 1000
}
```

#### Sample request

```shell-session
$ curl \
    --request POST \
    --header "X-Vault-Token: ..." \
    --data @payload.json \
    http://127.0.0.1:8200/v1/sys/quotas/lease-count/global-lease-count-quota
```

### Delete a lease count quota

A lease count quota can be deleted by `name`.

| Method   | Path                            |
| -------- | ------------------------------- |
| `DELETE` | `/sys/quotas/lease-count/:name` |

#### Sample request

```shell-session
$ curl \
    --request DELETE \
    --header "X-Vault-Token: ..." \
    http://127.0.0.1:8200/v1/sys/quotas/lease-count/global-lease-count-quota
```

### Get a lease count quota

A lease count quota can be retrieved by `name`.

| Method | Path                            |
| ------ | ------------------------------- |
| `GET`  | `/sys/quotas/lease-count/:name` |

#### Sample request

```shell-session
$ curl \
    --request GET \
    --header "X-Vault-Token: ..." \
    http://127.0.0.1:8200/v1/sys/quotas/lease-count/global-lease-count-quota
```

#### Sample response

```json
{
  "request_id": "21514bc6-2c19-42b9-a8a7-cab27aff5815",
  "lease_id": "",
  "lease_duration": 0,
  "renewable": false,
  "data": {
    "max_leases": 1000,
    "name": "global-lease-count-quota",
    "path": "",
    "role": "",
    "type": "lease-count"
  },
  "warnings": null
}
```

### List lease count quotas

This endpoint returns a list of all the lease count quotas. A 404 response will be returned if no lease count quota has been created.

| Method | Path                      |
| ------ | ------------------------- |
| `LIST` | `/sys/quotas/lease-count` |

#### Sample request

```shell-session
$ curl \
    --request LIST \
    --header "X-Vault-Token: ..." \
    http://127.0.0.1:8200/v1/sys/quotas/lease-count
```

#### Sample response

```json
{
  "auth": null,
  "data": {
    "keys": ["global-lease-count-quota"]
  },
  "lease_duration": 0,
  "lease_id": "",
  "renewable": false,
  "request_id": "ab633ee1-a692-ba03-083b-f1bd91c51c28",
  "warnings": null,
  "wrap_info": null
}
