Is it possible to create a json/yaml file in a pipeline?

[johnthompson-ybor]

I'd like to be able to make a new json or yaml file when generating an application so I can use it with the argocd git file application set generator. I can currently copy or download an empty {} json file and then edit it with json-update, but it would be nice to also be able to just generate a file from scratch.

Currently, there is not.

generate a file from scratch

"Generate" is vague. The details in the file come from somewhere. The thing I see as possibly reasonable here would be a general-purpose file-writer step (not JSON-specific; not YAML-specific) that takes allows users to define the contents of a new file using an expression.

Feel free to open a feature request.
