Usage: vault lease revoke [options] ID

  Revokes secrets by their lease ID. This command can revoke a single secret
  or multiple secrets based on a path-matched prefix.

  The default behavior when not using -force is to revoke asynchronously; Vault
  will queue the revocation and keep trying if it fails (including across
  restarts). The -sync flag can be used to force a synchronous operation, but
  it is then up to the caller to retry on failure. Force mode always operates
  synchronously.

  Revoke a single lease:

      $ vault lease revoke database/creds/readonly/2f6a614c...

  Revoke all leases for a role:

      $ vault lease revoke -prefix aws/creds/deploy

  Force delete leases from Vault even if secret engine revocation fails:

      $ vault lease revoke -force -prefix consul/creds

  For a full list of examples and paths, please see the documentation that
  corresponds to the secret engine in use.
