VSTS - Create Process Parameters in Release Defintion

Question

In Visual Studion Teams Services Build Definitions I can outsource Task Settings to Process Parameters by clicking on the (i) icon and then on "Link".

I really like this feature and I would like to do the same in a Release Definition. But I cannot find a way to create Process Parameters in a Release Definition (no "Link" option). If I select one of the Release Defintion Templates (e.g. Azure App Service Deployment) there are a few OOTB Process Parameters which I can use, but I cannot create new parameters. I cannot use variables as they only store string values and for some release tasks, specific settings (e.g. Azure Subscription) cannot use a variable but a parameter.

Answer 1

While this isn't supported in the GUI yet, you should be able to do accomplish this on the underlying json you can export from VSTS. This json has a processParameters collection for each environment, and a dataSourceBindings. Here is a screenshot showing how to do an Azure Subscription.

Answer 2

The Process parameters feature is only available in build editor. What are process parameters?

Regarding some settings of some release tasks (e.g. Azure Subscription), you can’t use variable, but you can custom build/release task to support it. (Add a Build task)

On the other hand, you can’t create/add new parameters to release task dynamically, just can specify the parameters in arguments input box.
