annotations property

Custom metadata about the secret.

Annotations are distinct from various forms of labels. Annotations exist to allow client tools to store their own state information without requiring a database. Annotation keys must be between 1 and 63 characters long, have a UTF-8 encoding of maximum 128 bytes, begin and end with an alphanumeric character ([a-z0-9A-Z]), and may have dashes (-), underscores (_), dots (.), and alphanumerics in between these symbols. The total size of annotation keys and values must be less than 16KiB.

Optional.
