I wondered if there is a way to define the docker image of as task as an parameter in a workflow. Or even better to define the pod_template (we also have a sidecar container that we want to specify) of a task on workflow level. Background is that we want to say: please use this version of the docker image (which has the software version that we want to test) in this specific run. Next run we want to execute another docker image (version of our software). What I tried is this, but this seems not to work:

@workflow
def override_wf(image: str = "default-image") -> str:
    out1 = step1()
    # Seems not to work :(
    out2 = step2(var=out1).with_overrides(container_image=image)

Just curious, how are you checking whether it works?

I have the same issue. It is not working because image in

step2(var=out1).with_overrides(container_image=image)

is in type of promise, but

contrainer_image

wants a string.

Thanks for asking! I wanted to try out dynamic workflows somewhen next week, this may help. I keep you posted.

@alert-grass-20163 This solution works well for me. See if you want to give it a try.
