Is it possible to mix
@flytekit.dynamic
&
with_overrides
? Curious if we could pass a resource configuration object to a workflow at runtime and have the
@dynamic
step specify overrides at runtime

Yes you should be able to
That was one of the intended usecases

Ah, I was trying to parameterize a workflow with `cpu`/`mem` so that we could dynamically specify them as arguments (in lieu of https://github.com/flyteorg/flyte/issues/475)
Looks like this successfully compiles w/ dynamic but if there's a sub-workflow (
@workflow
, not
@dynamic
) then it leads to the following error
Copy code
AttributeError: 'Promise' object has no attribute 'cpu'
Although, when actually examining the pod in the cluster it looks like supplying args to
with_overrides
for limits doesn't have any effect/I still see the following when running
kubectl describe
on one of the pods (when I specified
cpu="1"
&
mem=100Mi
)
Copy code
Limits:
      cpu:     100m
      memory:  200Mi
    Requests:
      cpu:     100m
      memory:  200Mi
If I hard-code the values in it seems to work fine but it doesn't appear to be possible to specify
with_overrides
w/ an argument to a workflow
Copy code
'VoidPromise' object has no attribute 'with_overrides'
If anyone on the team could provide an example of setting overrides in a dynamic step based on an argument that'd be very helpful..seems like it's possible per https://flyte-org.slack.com/archives/CP2HDHKE1/p1655135984234209, but I must be missing something…

I guess mixing
@flytekit.dynamic
and
with_overrides
isn’t yet possible. @Smriti Satyan, I remember you telling that this didn’t work. Could you elaborate more on this, please?

Thats right @Samhita Alla. Facilitating
dynamic
with
with_overrides
is a work in progress. Right now, it can't be used. cc @Yee If we try to use
with_overrides
with
dynamic
workflow, it fails to execute.

@Rahul Mehta I am sorry in that case, let us look into this tomorrow. For some reason this feels like a bug

cc @Yee
It works for me on a production cluster
it does not work locally, but that is because of the way we interpret it and that should be a more complex fix to make it run locally

Ah this was on a production cluster with the sandbox helm chart deployed. To confirm I was running on remote. I'll upgrade all the deps and give this a shot next week

Confirmed this is no longer an issue on the most recent version of the chart that I deployed. Thanks again @Ketan (kumare3)!

Interesting, I don't even know we fixed it

This is definitely going to be very powerful and is the final blocker we had to fully moving towards flyte 🙂
