Usage: vault renew [options] ID
|
|
|
|
Renews the lease on a secret, extending the time that it can be used before
|
|
it is revoked by Vault.
|
|
|
|
Every secret in Vault has a lease associated with it. If the owner of the
|
|
secret wants to use it longer than the lease, then it must be renewed.
|
|
Renewing the lease does not change the contents of the secret. The ID is the
|
|
full path lease ID.
|
|
|
|
Renew a secret:
|
|
|
|
$ vault renew database/creds/readonly/2f6a614c-4aa2-7b19-24b9-ad944a8d4de6
|
|
|
|
Lease renewal will fail if the secret is not renewable, the secret has already
|
|
been revoked, or if the secret has already reached its maximum TTL.
|
|
|
|
For a full list of examples, please see the documentation.
