Usage: consul acl token create [options]
|
|
|
|
When creating a new token policies may be linked using either the -policy-id
|
|
or the -policy-name options. When specifying policies by IDs you may use a
|
|
unique prefix of the UUID as a shortcut for specifying the entire UUID.
|
|
|
|
Create a new token:
|
|
|
|
$ consul acl token create -description "Replication token"
|
|
-policy-id b52fc3de-5
|
|
-policy-name "acl-replication"
|
|
