`default_lease_ttl` or `max_lease_ttl` values of 0 mean that the system defaults
are used by this backend.

## Enable Secrets Engine

This endpoint enables a new secrets engine at the given path.

| Method | Path                |
| :----- | :------------------ |
| `POST` | `/sys/mounts/:path` |

### Parameters

- `path` `(string: <required>)` – Specifies the path where the secrets engine
  will be mounted. This is specified as part of the URL.

  !> **NOTE:** Use ASCII printable characters to specify the desired path.

- `type` `(string: <required>)` – Specifies the type of the backend, such as
  "aws".

- `description` `(string: "")` – Specifies the human-friendly description of the
  mount.

- `config` `(map<string|string>: nil)` – Specifies configuration options for
  this mount; if set on a specific mount, values will override any global
  defaults (e.g. the system TTL/Max TTL)

  - `default_lease_ttl` `(string: "")` - The default lease duration, specified
    as a string duration like "5s" or "30m".

  - `max_lease_ttl` `(string: "")` - The maximum lease duration, specified as a
    string duration like "5s" or "30m".

  - `force_no_cache` `(bool: false)` - Disable caching.

  - `audit_non_hmac_request_keys` `(array: [])` - Comma-separated list of keys
    that will not be HMAC'd by audit devices in the request data object.

  - `audit_non_hmac_response_keys` `(array: [])` - Comma-separated list of keys
    that will not be HMAC'd by audit devices in the response data object.

  - `listing_visibility` `(string: "")` - Specifies whether to show this mount
    in the UI-specific listing endpoint. Valid values are `"unauth"` or
    `"hidden"`. If not set, behaves like `"hidden"`.

  - `passthrough_request_headers` `(array: [])` - Comma-separated list of headers
    to whitelist and pass from the request to the plugin.

  - `allowed_response_headers` `(array: [])` - Comma-separated list of headers
    to whitelist, allowing a plugin to include them in the response.

- `options` `(map<string|string>: nil)` - Specifies mount type specific options
  that are passed to the backend.

  _Key/Value (KV)_

  - `version` `(string: "1")` - The version of the KV to mount. Set to "2" for mount
    KV v2.

Additionally, the following options are allowed in Vault open-source, but
relevant functionality is only supported in Vault Enterprise:

- `local` `(bool: false)` – Specifies if the secrets engine is a local mount
  only. Local mounts are not replicated nor (if a secondary) removed by
  replication.

- `seal_wrap` `(bool: false)` - Enable seal wrapping for the mount, causing
  values stored by the mount to be wrapped by the seal's encryption capability.

- `external_entropy_access` `(bool: false)` - Enable the secrets engine to access
  Vault's external entropy source.

### Sample Payload

```json
{
  "type": "aws",
  "config": {
    "force_no_cache": true
  }
}
```

### Sample Request

```shell-session
$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    --data @payload.json \
    http://127.0.0.1:8200/v1/sys/mounts/my-mount
```

## Disable Secrets Engine

This endpoint disables the mount point specified in the URL.

| Method   | Path                |
| :------- | :------------------ |
| `DELETE` | `/sys/mounts/:path` | `204 (empty body)` |

### Sample Request

```shell-session
$ curl \
    --header "X-Vault-Token: ..." \
    --request DELETE \
    http://127.0.0.1:8200/v1/sys/mounts/my-mount
```

## Read Mount Configuration

This endpoint reads the given mount's configuration. Unlike the `mounts`
endpoint, this will return the current time in seconds for each TTL, which may
be the system default or a mount-specific value.

| Method | Path                     |
| :----- | :----------------------- |
| `GET`  | `/sys/mounts/:path/tune` |

### Sample Request

```shell-session
$ curl \
    --header "X-Vault-Token: ..." \
    http://127.0.0.1:8200/v1/sys/mounts/my-mount/tune
```

### Sample Response

```json
{
  "default_lease_ttl": 3600,
  "max_lease_ttl": 7200,
  "force_no_cache": false
}
```

## Tune Mount Configuration

This endpoint tunes configuration parameters for a given mount point.

| Method | Path                     |
| :----- | :----------------------- |
| `POST` | `/sys/mounts/:path/tune` |

### Parameters

- `default_lease_ttl` `(int: 0)` – Specifies the default time-to-live. This
  overrides the global default. A value of `0` is equivalent to the system
  default TTL.

- `max_lease_ttl` `(int: 0)` – Specifies the maximum time-to-live. This
  overrides the global default. A value of `0` are equivalent and set to the
  system max TTL.

- `description` `(string: "")` – Specifies the description of the mount. This
  overrides the current stored value, if any.

- `audit_non_hmac_request_keys` `(array: [])` - Specifies the comma-separated
  list of keys that will not be HMAC'd by audit devices in the request data
  object.

- `audit_non_hmac_response_keys` `(array: [])` - Specifies the comma-separated
  list of keys that will not be HMAC'd by audit devices in the response data
  object.

- `listing_visibility` `(string: "")` - Specifies whether to show this mount in
  the UI-specific listing endpoint. Valid values are `"unauth"` or `"hidden"`.
  If not set, behaves like `"hidden"`.

- `passthrough_request_headers` `(array: [])` - Comma-separated list of headers
  to whitelist and pass from the request to the plugin.

- `allowed_response_headers` `(array: [])` - Comma-separated list of headers
  to whitelist, allowing a plugin to include them in the response.

{
  "default_lease_ttl": 1800,
  "max_lease_ttl": 3600
