kv put

The kv put command writes the data to the given path in the K/V secrets engine.

If working with K/V v2, this command creates a new version of a secret at the specified location. If working with K/V v1, this command stores the given secret at the specified location.

Regardless of the K/V version, if the value does not yet exist at the specified path, the calling token must have an ACL policy granting the "create" capability. If the value already exists, the calling token must have an ACL policy granting the "update" capability.

Examples​

Writes the data to the key "creds":

$ bao kv put -mount=secret creds passcode=my-long-passcode

The data can also be consumed from a file on disk by prefixing with the "@" symbol. For example:

$ bao kv put -mount=secret foo @data.json

Or it can be read from stdin using the "-" symbol:

$ echo "abcd1234" | bao kv put -mount=secret foo bar=-

Usage​

There are no flags beyond the standard set of flags included on all commands.

Output options​

  • -field (string: "") - Print only the field with the given name. Specifying this option will take precedence over other formatting directives. The result will not have a trailing newline making it ideal for piping to other processes.

  • -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.

Command options​

  • -cas (int: 0) - Specifies to use a Check-And-Set operation. If not set the write will be allowed. In order for a write to be successful, cas must be set to the current version of the secret. If set to 0 a write will only be allowed if the key doesn’t exist as unset keys do not have any version information. Also remember that soft deletes do not remove any underlying version data from storage. In order to write to a soft deleted key, the cas parameter must match the key's current version. The default is -1.

  • -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.
