Usage: nomad acl token create [options]
Create is used to issue new ACL tokens. Requires a management token.
General Options:
` + generalOptionsUsage(usageOptsDefault|usageOptsNoNamespace) + `
Create Options:
-name=""
Sets the human readable name for the ACL token.
-type="client"
Sets the type of token. Must be one of "client" (default), or "management".
-global=false
Toggles the global mode of the token. Global tokens are replicated to all regions.
-policy=""
Specifies a policy to associate with the token. Can be specified multiple times,
but only with client type tokens.
-role-id
ID of a role to use for this token. May be specified multiple times.
-role-name
Name of a role to use for this token. May be specified multiple times.
-ttl
Specifies the time-to-live of the created ACL token. This takes the form of
a time duration such as "5m" and "1h". By default, tokens will be created
without a TTL and therefore never expire.
