FileSystemSecretStore

Manage a store of secrets held in files, specified as follows:

Each file must contain only one secret.
The file must be in the directory specified by the property directory.
The filename must match the mappings property secretId.
The file content must match the mappings property format. For example, if the mapping specifies BASE64, the file content must be base64-encoded.

This Secret store can manage secrets of both GenericSecret and CryptoKey types when used with dedicated formats.

Secrets are read lazily from the filesystem.

The secrets provider queries the FileSystemSecretStore for a named secret, identified by the name of a file in the specified directory, without the prefix/suffix defined in the store configuration. The FileSystemSecretStore returns the secret that exactly matches the name.

The secrets provider builds the secret, checking that the secret’s constraints are met, and returns a unique secret. If the secret’s constraints aren’t met, the secrets provider cannot build the secret and the secret query fails.

Usage

{
  "name": string,
  "type": "FileSystemSecretStore",
  "config": {
    "directory": configuration expression<string>,
    "format": SecretPropertyFormat reference,
    "versionSuffix": configuration expression<string>,
    "suffix": configuration expression<string>,
    "mappings": [ object, ... ],
    "leaseExpiry": configuration expression<duration>,
    "autoRefresh": object
  }
}

Properties

"directory": configuration expression<string>, required

File path to a directory containing secret files. This object checks the specified directory, but not its subdirectories.

format: SecretPropertyFormat reference, optional

Format in which the secret is stored. Use one of the following values or formats:

BASE64: Base64-encoded
PLAIN: Plain text
A JwkPropertyFormat
A PemPropertyFormat

Default: BASE64

"versionSuffix": configuration expression<string>, optional

A version suffix, such as .v, not including any version numbers.

For details, refer to the examples that follow.

Default: None

"suffix": configuration expression<string>, optional

A file suffix or extension, such as .secret.

For details, refer to the examples that follow.

Default: None

"mappings": array of objects, optional

One or more mappings to define a secret:

secretId: configuration expression<secret-id>, required: The ID of the secret used in your configuration.
format: SecretPropertyFormat reference, required: The format and algorithm of the secret. Use SecretKeyPropertyFormat or PemPropertyFormat.

"leaseExpiry": configuration expression<duration>, optional

The amount of time that secrets produced by this store can be cached before they must be refreshed.

If the duration is zero or unlimited, PingGateway issues a warning, and uses the default value.

Default: 5 minutes

"autoRefresh": object, optional

Automatically reload the FileSystemSecretStore when a file is edited or deleted in the directory given by directory.

When autoRefresh is triggered, secrets and keys are refreshed even if the leaseExpiry has not expired. When autoRefresh is triggered, the leaseExpiry is reset.

{
  "enabled": configuration expression<boolean>,
  "executor": ScheduledExecutorService reference
}

enabled: configuration expression<boolean>, optional

Flag to enable or disable automatic reload:

true: Enable
false: Disable

Default: true

"executor": ScheduledExecutorService reference, optional

A ScheduledExecutorService to monitor the filesystem.

Default: The default ScheduledExecutorService in the heap

Log level

To facilitate debugging secrets for the FileSystemSecretStore, in logback.xml add a logger defined by the fully qualified package name of the property resolver. The following line in logback.xml sets the log level to ALL:

<logger name="org.forgerock.secrets.propertyresolver" level="ALL" />

Examples

The following example FileSystemSecretStore matches example.pem, example.v1.pem, and example.v2.pem. The active secret file is the one with the largest version number, mySecret.v2.pem:

{
  "name": "FileSystemSecretStore-1",
  "type": "FileSystemSecretStore",
  "config": {
    "directory": "&{secretsDir}",
    "format": "PLAIN",
    "versionSuffix": ".v",
    "suffix": ".pem",
    "mappings": [
      {
        "secretId": "example",
        "format": "pemPropertyFormat"
      }
    ]
  }
}
