issue about tosca.capabilities.Compute

[Lishitao <lishitao@huawei.com>]

Hi Chris, Matt and all

 

I went through tosca-simple-profile-yaml document today, and find out an issue in the document.

 

In tosca.nodes.Compute, it contains

 

capabilities:

    host:

      type: tosca.capabilities.Compute

      valid_source_types: [tosca.nodes.SoftwareComponent]

 

and in tosca.nodes.SoftwareComponent it contains

 

requirements:

    - host:

        capability: tosca.capabilities.Compute

        node: tosca.nodes.Compute

        relationship: tosca.relationships.HostedOn

 

the above model is a basic model based on requirement-capability in TOSCA.

 

Then I find out that

 

tosca.nodes.WebServer:

  derived_from: tosca.nodes.SoftwareComponent

  capabilities:

    # Private, layer 4 endpoints

    data_endpoint: tosca.capabilities.Endpoint

    admin_endpoint: tosca.capabilities.Endpoint.Admin

    host:

      type: tosca.capabilities.Compute

      valid_source_types: [ tosca.nodes.WebApplication ]

 

how can Webserver node (derived from SoftwareComponent) also contains the tosca.capabilities.Compute capability?

Should here be tosca.capabilities.container?

 

The same issue is for

 

tosca.nodes.Container.Runtime:

  derived_from: tosca.nodes.SoftwareComponent

  capabilities:

    host:

      type: tosca.capabilities.Compute

      valid_source_types: [tosca.nodes.Container.Application]

    scalable:

      type: tosca.capabilities.Scalable
