/sys/mounts

The /sys/mounts endpoint is used manage secrets engines in Vault.

List Mounted Secrets Engines

This endpoints lists all the mounted secrets engines.

Method	Path	Produces
GET	/sys/mounts	200 application/json

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \
    http://127.0.0.1:8200/v1/sys/mounts

Sample Response

{
  "aws": {
    "type": "aws",
    "description": "AWS keys",
    "config": {
      "default_lease_ttl": 0,
      "max_lease_ttl": 0,
      "force_no_cache": false,
      "seal_wrap": false
    }
  },
  "sys": {
    "type": "system",
    "description": "system endpoint",
    "config": {
      "default_lease_ttl": 0,
      "max_lease_ttl": 0,
      "force_no_cache": false,
      "seal_wrap": false
    }
  }
}

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	Produces
POST	/sys/mounts/:path	204 (empty body)

Parameters

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

• 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. This is an object with four possible values:

  • 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 backend.

    These control the default and maximum lease time-to-live, and the force disabling backend caching. They override the global defaults if set on a specific mount.

    When used with supported seals (pkcs11, awskms, etc.), seal_wrap causes key material for supporting mounts to be wrapped by the seal's encryption capability. This is currently only supported for transit and pki backends. This is only available in Vault Enterprise.

• 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.

Sample Payload

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

Sample Request

$ 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	Produces
DELETE	/sys/mounts/:path	204 (empty body)

Sample Request

$ 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	Produces
GET	/sys/mounts/:path/tune	200 application/json

Sample Request

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

Sample Response

{
  "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	Produces
POST	/sys/mounts/:path/tune	204 (empty body)

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 backend.

Sample Payload

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