Argo workflow conditionally pass command parameter

[kkozmic]

I have a workflow with a step that calls a python script through something like:

      command:
      - poetry
      - run
      - python
      - my_script.py
      - --force
      - --input-file
      - /tmp/metrics.json
      - --output-folder
      - /tmp

I also have an input parameter like

    inputs:
      parameters:
      - name: force
        value: "true"

I want to include the --force flag when invoking my command only when the force parameter is true and ommit it otherwise, but I can't for the life of me figure out how to do it.

I'm sure it must be possible, so any help would be greatly appreciated.

You'll probably want to use conditional parameters. However, this won't be available until v3.1 (we're currently still in v3.0 RC).

Thanks @simster7

Yeah, that possibly looks like something that might solve it. Notice in my example I'm looking to conditionally include (or not) a value in an array (for the command). Not sure if that's going to be a supported scenario here.

Is there another way to achieve it in the current version or not until v3.1 is released?

I just ran into this issue while doing some testing and I agree something like this is needed... I'll see if I can find a workaround
