Components reference 编辑

In the components construct, you refer to top-level component in the StyleBook by using the $components.<componentname> notation. If there are nested components within a top-level component, then the notation used is $components.<componentname>.components.<component-name> to refer to them, and so on.

Example:

components:
 -
    name: my-lbvserver-comp
     type: ns::lbvserver
     properties:
           name: $parameters.name + "-lb"
           servicetype: HTTP
           ipv46: $parameters.ip
           port: 80
           lbmethod: $parameters.lb-alg
  -
     name: my-svcg-comp
     type: ns::servicegroup
     properties:
          name: $parameters.name + "-svcgrp"
          servicetype: HTTP
 -
     name: members-svcg-comp
     type: ns::servicegroup_servicegroupmember_binding
     repeat: $parameters.svc-servers
     repeat-item: srv
     properties:
        ip: $srv
          port: str($parameters.svc-port)
          servicegroupname: $components.my-svcg-comp.properties.name
 -
     name: lbvserver-svg-binding-comp
     type: ns::lbvserver_servicegroup_binding
     properties:
            name: $components.my-lbvserver-comp.properties.name
            servicegroupname: $components.my-svcg-comp.properties.name
<!--NeedCopy-->

In this example, the components my-svcg-comp and my-lbvserver-comp have to be built before building the last component lbvserver-svg-binding-comp because there are references to these components in this last component. These references are provided by using the components references denoted by $components.<componentname>.
