             Summary: Flag for allowing uninstall workflow to skip failed operations
                 Key: ARIA-196
                 URL: https://issues.apache.org/jira/browse/ARIA-196
             Project: AriaTosca
          Issue Type: Story
            Reporter: Ran Ziv
            Priority: Minor


The {{uninstall}} workflow will fail and stop on any failed task (like any other workflow by default).

In some scenarios this could be problematic, for example if a part of the topology has already been uninstalled manually or so, and the user wants to uninstall the rest of it.

It could be useful to have a flag which will make the {{uninstall}} workflow skip failed operations and continue the workflow execution, so the remaining uninstall operations would run as well.

This could be done by having the {{uninstall}} worklfow create the tasks with the {{ignore_failure}} flag set to {{True}}.
There should be some sort of flag telling the {{uninstall}} workflow to do so, keeping in mind that the workflow is not supposed to receive any parameters according to TOSCA.
