Usage: vault token-create [options]

  Create a new auth token.

  This command creates a new token that can be used for authentication.
  This token will be created as a child of your token. The created token
  will inherit your policies, or can be assigned a subset of your policies.

  A lease can also be associated with the token. If a lease is not associated
  with the token, then it cannot be renewed. If a lease is associated with
  the token, it will expire after that amount of time unless it is renewed.

  Metadata associated with the token (specified with "-metadata") is
  written to the audit log when the token is used.

  If a role is specified, the role may override parameters specified here.

General Options:
` + meta.GeneralOptionsUsage() + `
Token Options:

  -id="7699125c-d8...."   The token value that clients will use to authenticate
                          with vault. If not provided this defaults to a 36
                          character UUID. A root token is required to specify
                          the ID of a token.

  -display-name="name"    A display name to associate with this token. This
                          is a non-security sensitive value used to help
                          identify created secrets, i.e. prefixes.

  -lease="1h"             Deprecated; use "-ttl" instead.

  -ttl="1h"               TTL to associate with the token. This option enables
                          the tokens to be renewable.

  -metadata="key=value"   Metadata to associate with the token. This shows
                          up in the audit log. This can be specified multiple
                          times.

  -orphan                 If specified, the token will have no parent. Only
                          root tokens can create orphan tokens. This prevents
                          the new token from being revoked with your token.

  -no-default-policy      If specified, the token will not have the "default"
                          policy included in its policy set.

  -policy="name"          Policy to associate with this token. This can be
                          specified multiple times.

  -use-limit=5            The number of times this token can be used until
                          it is automatically revoked.

  -format=table           The format for output. By default it is a whitespace-
                          delimited table. This can also be json or yaml.

  -role=name              If set, the token will be created against the named
                          role. The role may override other parameters. This
                          requires the client to have permissions on the
                          appropriate endpoint (auth/token/create/<name>).
