KubernetesSecretParameterProvider
Description
Fetches parameters from files, in the format provided by Kubernetes mounted secrets. Parameter groups are indicated by a set of directories, and files within the directories map to parameter names. The content of the file becomes the parameter value. Since Kubernetes mounted Secrets are base64-encoded, the parameter provider defaults to Base64-decoding the value of the parameter from the file.

Properties
In the list below required Properties are shown with an asterisk (*). Other properties are considered optional. The table also indicates any default values, and whether a property supports the NiFi Expression Language.
| Display Name | API Name | Default Value | Allowable Values | Description |
|---|---|---|---|---|
| Parameter Group Directories * | parameter-group-directories | A comma-separated list of directory absolute paths that will map to named parameter groups. Each directory that contains files will map to a parameter group, named after the innermost directory in the path. Files inside the directory will map to parameter names, whose values are the content of each respective file. | ||
| Parameter Value Byte Limit * | parameter-value-byte-limit | 256 B | The maximum byte size of a parameter value. Since parameter values are pulled from the contents of files, this is a safeguard that can prevent memory issues if large files are included. | |
| Parameter Value Encoding * | parameter-value-encoding | Base64 |
| Indicates how parameter values are encoded inside Parameter files. |
