Usage: nomad acl role <subcommand> [options] [args]
|
||
|
|
|
||
|
|
This command groups subcommands for interacting with ACL roles. Nomad's ACL
|
||
|
|
system can be used to control access to data and APIs. ACL roles are
|
||
|
|
associated with one or more ACL policies which grant specific capabilities.
|
||
|
|

|
||
|
|
|
||
|
|
Create an ACL role:
|
||
|
|
|
||
|
|
$ nomad acl role create -name="name" -policy-name="policy-name"
|
||
|
|
|
||
|
|
List all ACL roles:
|
||
|
|
|
||
|
|
$ nomad acl role list
|
||
|
|
|
||
|
|
Lookup a specific ACL role:
|
||
|
|
|
||
|
|
$ nomad acl role info <acl_role_id>
|
||
|
|
|
||
|
|
Update an ACL role:
|
||
|
|
|
||
|
|
$ nomad acl role update -name="updated-name" <acl_role_id>
|
||
|
|
|
||
|
|
Delete an ACL role:
|
||
|
|
|
||
|
|
$ nomad acl role delete <acl_role_id>
|
||
|
|
|
||
|
|
Please see the individual subcommand help for detailed usage information.
