- Modeling team accept a multiple node design in service template (Anatoly Katzman )
- SDC supports input List structure multiple node design in TOSCA service template (Ofir Sonsino )
- SO support List input interface(Seshu Kumar Mudiganti )
The ideal solution should be that a CCVPN service can be instantiated by using one service template and customers can decide the number of resources when creating a service.
TOSCA working group also pays attention to this problem and they came up with an improved service templates which can satisfy our needs:
Keyname | Required | Type | Constraints | Description |
occurrences | no | range of integer | when not specified, defaults to [1,1] | The optional minimum and maximum number of instances that can be created from this node template. If not specified, only one single instance can be created. |
instance_count | no | integer | when not specified, defaults to the lower bound of the range specified by the ‘occurrences’ keyname | The requested number of runtime instance of the node template. |
