/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.

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 KV 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. Quotas cannot be created or modified in parent or sibling namespaces. Note, namespaces are supported in Enterprise only.
• 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
• 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
• 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

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

Sample request

$ 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. Quotas that exist in a parent or a sibling namespace cannot be deleted.

Sample request

$ 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.

Sample request

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

Sample response

{
  "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 across all namespaces. Note that this level of access differs from creating, updating, and deleting quotas which restricts access to parent and sibling namespaces. A 404 response will be returned if no lease count quota has been created.

Sample request

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

Sample response

{
  "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
