Usage: nomad acl binding-rule <subcommand> [options] [args]

  This command groups subcommands for interacting with ACL binding rules.
  Nomad's ACL system can be used to control access to data and APIs. For a full
  guide see: https://www.nomadproject.io/guides/acl.html

  Create an ACL binding rule:

      $ nomad acl binding-rule create \
          -auth-method=auth0 \
          -selector="nomad-engineering in list.groups" \
          -bind-type=role \
          -bind-name="custer-admin" \

  List all ACL binding rules:

      $ nomad acl binding-rule list

  Lookup a specific ACL binding rule:

      $ nomad acl binding-rule info <acl_binding_rule_id>

  Update an ACL binding rule:

      $ nomad acl binding-rule update \
          -description="nomad engineering team" \
          <acl_binding_rule_id>

  Delete an ACL binding rule:

      $ nomad acl binding-rule delete <acl_binding_rule_id>

  Please see the individual subcommand help for detailed usage information.
