             Summary: Define an C.8.5.5  tosca.artifact.implementation.exec
                 Key: TOSCA-263
                 URL: https://issues.oasis-open.org/browse/TOSCA-263
             Project: OASIS Topology and Orchestration Specification for Cloud Applications (TOSCA) TC
          Issue Type: New Feature
            Reporter: Luca Gioppo


At the moment artifacts are just files but we need to instruct orchestrator to do also execs like executing commands that is not only managinf files.
Commands could not just be executing shell scripts

Use case:
1) I want to execute a "puppet apply"; of course I could have a shell script to do that but is more prone to errors and delegate stuff outside the orchestrator in case of problems it become more complicated to get feedback and we want people that write TOSCA not to write too many things so adding a exec feature (much like common DevOps tools) is helpful (in the end the orchestrator is a sort of DevOps tool).
2) I want to execute docker run
