Usage: vault rotate [options]
Rotates the underlying encryption key which is used to secure data written
to the storage backend. This installs a new key in the key ring. This new
key is used to encrypted new data, while older keys in the ring are used to
decrypt older data.
This is an online operation and does not cause downtime. This command is run
per-cluser (not per-server), since Vault servers in HA mode share the same
storeage backend.
Rotate Vault's encryption key:
$ vault rotate
For a full list of examples, please see the documentation.
