Hi comm, I'm new to Flyte. I have been trying to get around this, but don't know what the issue is. I installed the flyte sandbox to test things out. When I run a workflow locally, it works fine and completed (typically completed in 3 mins). However, when I run it remotely in the sandbox, it takes very long time (about an hour) and eventually fails with this error:

Pod failed. No message received from kubernetes.

Welcome @Fhuad Balogun to the community. Have you run

flytectl demo start

to spin up the cluster? And what workflow are you trying to run?

Yes I have

HI @Fhuad Balogun could you share the output of

kubectl get pods -n flyte

Could you also share the output of

kubcetl logs <pod-name> -n flytesnacks-development

? You can get the pod that's erroring out by running

kubectl get pods -n flytesnacks-development

considering

flytesnacks-development

is the namespace you triggered the workflow in.

Thanks guys @David Espejo @Samhita Alla This is the error I get on describing the pod in

flytesnacks-development

namespace (screenshot) And when I check the logs, it says trying and failing to pull image.

I believe your system isn't allowing you to pull the image.

Thanks @Samhita Alla still didn't work. However, I'm already going deeper into registering workflows. I want to ask, how do I ship in all necessary packages that are needed to make a workflow run successfully? for example, I've modularized my code and the tasks arranged into a workflow are in different modules of the project, will Flyte be able to package all these when I run "pyflyte register", "pyflyte packages" or "flytctl register"? Also, how do I register workflows with different tasks from a Jupyter Notebook?

@Fhuad Balogun, you can use

pyflyte register

to package up all your tasks and workflows present in different modules. You can register workflows from a Jupyter notebook using

register_workflow

method: https://github.com/flyteorg/flytekit/blob/707fc03b88ec08fb10d60ac642f3c80e275bd90c/tests/flytekit/unit/remote/test_sandbox.py#L70-L77.

Ok. Thank you very much.
