kv metadata

warning

NOTE: This is a K/V Version 2 secrets engine command, and not available for Version 1.

The kv metadata command has subcommands for interacting with the metadata and versions for the versioned secrets (K/V Version 2 secrets engine) at the specified path.

Usage​

Usage: bao kv metadata <subcommand> [options] [args]

  # ...

Subcommands:
    delete    Deletes all versions and metadata for a key in the KV store
    get       Retrieves key metadata from the KV store
    put       Sets or updates key settings in the KV store

kv metadata delete​

The kv metadata delete command deletes all versions and metadata for the provided key.

Examples​

Deletes all versions and metadata of the key "creds":

$ bao kv metadata delete -mount=secret creds
Success! Data deleted (if it existed) at: secret/metadata/creds

kv metadata get​

The kv metadata get command retrieves the metadata of the versioned secrets at the given key name. If no key exists with that name, an error is returned.

Examples​

Retrieves the metadata of the key name, "creds":

$ bao kv metadata get -mount=secret creds
=== Metadata Path ===
secret/metadata/creds

kv metadata put​

The kv metadata put command can be used to create a blank key in the K/V v2 secrets engine or to update key configuration for a specified key.

Examples​

Create a key in the K/V v2 with no data at the key "creds":

$ bao kv metadata put -mount=secret creds
Success! Data written to: secret/metadata/creds

Set the maximum number of versions to keep for the key "creds":

$ bao kv metadata put -mount=secret -max-versions=5 creds
Success! Data written to: secret/metadata/creds

NOTE: If not set, the backend’s configured max version is used. Once a key has more than the configured allowed versions the oldest version will be permanently deleted.

Require Check-and-Set for the key "creds":

$ bao kv metadata put -mount=secret -cas-required creds

NOTE: When check-and-set is required, the key will require the cas parameter to be set on all write requests. Otherwise, the backend’s configuration will be used.

Set the length of time before a version is deleted for the key "creds":

$ bao kv metadata put -mount=secret -delete-version-after="3h25m19s" creds

NOTE: If not set, the backend's configured Delete-Version-After is used. If set to a duration greater than the backend's, the backend's Delete-Version-After setting will be used. Any changes to the Delete-Version-After setting will only be applied to new versions.

Output options​

  • -format (string: "table") - Print the output in the given format. Valid formats are "table", "json", or "yaml". This can also be specified via the BAO_FORMAT environment variable.

Subcommand options​

  • -cas-required (bool: false) - If true the key will require the cas parameter to be set on all write requests. If false, the backend’s configuration will be used. The default is false.

  • -max-versions (int: 0) - The number of versions to keep per key. If not set, the backend’s configured max version is used. Once a key has more than the configured allowed versions the oldest version will be permanently deleted.

  • -delete-version-after (string:"0s") – Set the delete-version-after value to a duration to specify the deletion_time for all new versions written to this key. If not set, the backend's delete_version_after will be used. If the value is greater than the backend's delete_version_after, the backend's delete_version_after will be used. Accepts duration format strings.

  • -custom-metadata (string: "") - Specifies a key-value pair for the custom_metadata field. This can be specified multiple times to add multiple pieces of metadata.

  • -mount (string: "") - Specifies the path where the KV backend is mounted. If specified, the next argument will be interpreted as the secret path. If this flag is not specified, the next argument will be interpreted as the combined mount path and secret path, with /data/ automatically inserted for KV v2 secrets.
