Re: get_artifact function usage

[Tal Liron]

1) You can embed files and the execution plugin can reference them and copy
them remotely.
2) You can define artifact types and attach them to node types and
templates, and all that is parsed correctly.

By "divorced" I mean that those two mechanisms are separate. The goal is to
have every file be a valid TOSCA "artifact".

Re: get_artifact function usage

[Tal Liron]

ARIA currently supports copying scripts remotely as part of the execution
plugin. They are expected to be in the CSAR. But this mechanism is
currently totally divorced from the TOSCA artifact structure.

Hi Tal,

Thanks for the clarification. When we say download, does the artifact can be at 
remote location or part of the CSAR ?

Sorry, I forgot to answer this. The answer is not good: sadly, there is no 
solid support for artifacts in ARIA right now beyond parsing. This function is 
currently a no-op.

Rather than just implement this function, I think it should be tackled as part 
of comprehensive support for artifacts: validation, downloading, copying, and 
verification. I think we have a JIRA for it somewhere but I can't seem to find 
it.

Hi,

Do we have any comments on this ?

Subject: get_artifact function usage

Hi,

We were looking at "get_artifact" function usage in the service template. It 
seems we don't have an implementation for it currently.
The get_artifact function has the below grammer as per the spec.

get_artifact: [ , , ,  ]

We have few clarifications and questions over this.

Do we need to use the get_artifact function only for input value assignment 
within a specific operation ?

We have 3 options before as per the grammer

  1.  Retrieving artifact without specified location - without (location)
  2.  Retrieving artifact as a local path - with location as LOCAL_FILE
  3.  Retrieving artifact in a specified location - with location as user given 
path How does the orchestrator need to handle these 3 options With 1st option 
as per the example , it seems the orchestrator should host the provided 
artifact in a local path of remote URL and assign that URL to input variable.
With 2nd option the orchestrator should store the artifacts in a local path 
(orchestrator provided ) and have that path assigned to the input variable With 
3rd option the orchestrator should store the artifacts in a local path(user 
provided) and have that path assigned to the input variable With these 3 
options we also have an option to remove the artifact after the operation 
execution.
So the questions is when should the get_artifact be resolved ? Is it during the 
parsing or during the execution ?

Regards,
DJ
