Usage: vault token renew [options] [TOKEN]
Renews a token's lease, extending the amount of time it can be used. If a
TOKEN is not provided, the locally authenticated token is used. A token
accessor can be used as well. Lease renewal will fail if the token is not
renewable, the token has already been revoked, or if the token has already
reached its maximum TTL.
Renew a token (this uses the /auth/token/renew endpoint and permission):
$ vault token renew 96ddf4bc-d217-f3ba-f9bd-017055595017
Renew the currently authenticated token (this uses the /auth/token/renew-self
endpoint and permission):
$ vault token renew
Renew a token requesting a specific increment value:
$ vault token renew -increment=30m 96ddf4bc-d217-f3ba-f9bd-017055595017
For a full list of examples, please see the documentation.
