Artifacts questions

[Luca Gioppo <luca.gioppo@csi.it>]

On C.6.3.2 is stated that:

"TOSCA orchestrators expect node templates to provide either a deployment artifact or an implementation artifact of a defined artifact type that it is able to process."

 

In the examples it seems that there is a mix of deployment concepts and "implementation" concepts:

 

- if I understood well the deployment concept reading few lines below "... when encountering a deployment artifact on the create operation; will automatically attempt to deploy the artifact based upon its artifact type."

This is, I hope, clear enough orchestrator find deployment artifact of type zip and copy? unzip it? in any case does something with it (as you can see there is no clear and unique behaviour even here)

 

But then I find this example: B.8.1.3.3 Example: Retrieving artifact in a specified location

and I start to get confused. Who copy the implementation script "wordpress_install.sh" and where?

where is written that the the zip artifact is a deployment and if it is why do we need a create implementation to move it?

 

All this part is really difficult to understand also there is no simple example of the two type of artifacts and how they have to be used.

 

There should not be any interpretation of how to manage a type X artifact the operation linked to it should "copy" "unzip" "copy and unzip" but at the moment I have not found.
