In addition to standard CLI help using the -h or -help flag for
commands, Vault has a built-in path-help command that can be used to get
help for specific paths within Vault. These paths are used with the
API or read, write, delete commands in order to interact with Vault.
The help system is the easiest way to learn how to use the various systems
in Vault, and also allows you to discover new paths.
Important! The help system is incredibly important in day-to-day
use of Vault. As a beginner or experienced user of Vault, you'll be using
the help command a lot to remember how to use different components of
Vault. Note that the Vault Server must be running and the client configured
properly to execute this command to look up paths.
Before using path-help, it is important to understand "paths" within Vault.
Paths are the parameters used for vault read, vault write, etc. An
example path is secret/foo, or aws/config/root. The paths available
depend on the enabled secrets engines. Because of this, the interactive
help is an indispensable tool to finding what paths are supported.
To discover what paths are supported, use vault path-help <mount point>.
For example, if you mounted the AWS secrets engine, you can use
vault path-help aws to find the paths supported by that backend. The paths
will be shown with regular expressions, which can make them hard to
parse, but they're also extremely exact.
You can try it right away with any Vault with vault path-help secret, since
secret is always mounted initially. The output from this command is shown
below and contains both a description of what that backend is for, along with
the paths it supports.
$vault path-help secret## DESCRIPTIONThe key/value backend reads and writes arbitrary secrets to the backend.The secrets are encrypted/decrypted by Vault: they are never storedunencrypted in the backend and the backend never has an opportunity tosee the unencrypted value.Leases can be set on a per-secret basis. These leases will be sent downwhen that secret is read, and it is assumed that some outside process willrevoke and/or replace the secret at that path.## PATHSThe following paths are supported by this backend. To view help forany of the paths below, use the help command with any route matchingthe path pattern. Note that depending on the policy of your auth token,you may or may not be able to access certain paths. ^.*$ Pass-through secret storage to the storage backend, allowing you to read/write arbitrary data into secret storage.

Once you've found a path you like, you can learn more about it by
using vault path-help <path> where "path" is a path that matches one of the
regular expressions from the backend help.
Or, if you saw an example online with vault write or some similar
command, you can plug that directly into vault path-help to learn about it
(assuming you have the proper backends mounted!).
For example, below we get the help for a single secret in the secret/
mount point. The help shows the operations that that path supports, the
parameters it takes (for write), and a description of that specific path.
$vault path-help secret/passwordRequest: passwordMatching Route: ^.*$Pass-through secret storage to the storage backend, allowing you toread/write arbitrary data into secret storage.## PARAMETERS lease (string) Lease time for this key when read. Ex: 1h## DESCRIPTIONThe pass-through backend reads and writes arbitrary data into secret storage,encrypting it along the way.A lease can be specified when writing with the "lease" field. If given, thenwhen the secret is read, Vault will report a lease with that duration. Itis expected that the consumer of this backend properly writes renewed keysbefore the lease is up. In addition, revocation must be handled by theuser of this backend.
