/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
GET	/sys/mounts

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
    }
  },
  "data": {
    "aws/": {
      "type": "aws",
      "description": "AWS keys",
      "config": {

        "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
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

{
  "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
DELETE	/sys/mounts/:path

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
GET	/sys/mounts/:path/tune

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
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
}
