Description

An abstract placeholder of a provider of onap.capabilities.Compute required from the cloud infrastructure.

In simplest cases, a dangling requirement of type onap.capabilities.Compute is sufficient to specify an abstraction of a Compute resource. The onap.capabilities.AbstractCompute is an additional option that allows the designer to clearly designate sharing of the same Compute by multiple components.

Usage Example

node_templates:
  # This node does not care how its Compute requirement will be satisfied
  part_1:
    type: PartOfMyFirewall
    requirements:
      - host:
          node_filter:
            properties:
              num_cpus: 2
              
  # These two nodes want to share the same Compute
  part_2:
    type: PartOfMyFirewall
    requirements:
      - host:
          node: compute_1
          capability: host
          
  part_3:
    type: PartOfMyFirewall
    requirements:
      - host:
          node: compute_1
