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" \
-role-id c630d4ef-6 \
-role-name "db-updater" \
-service-identity "web" \
-service-identity "db:east,west"
