Hi all - I'm writing an article about about using Flyte to run a docker container based workflow, much like this: https://docs.flyte.org/projects/cookbook/en/latest/auto/core/containerization/raw_container.html However when I try to run on my local sandbox the tasks all stall out

[ContainersNotReady|PodInitializing]: containers with unready status: [... flyte-copilot-sidecar]|

Is this because it can't access the image inside the sandbox, or something more complicated? Is there a way to get this type of ContainerTask example to work on the sandbox? As is, my article ends like this - 'So you can push the dag (

pyflyte run --remote ..

), see it in Flyte ui, but it won't run locally, so go find a prod server if you want to fullly test, ok gl with that bye'

Hi @nice-vr-73388 I don't think the docs are updated yet, but there is a new feature in

flyte demo

that spins up a container registry at

localhost:3000

. Pushing images will make them available to the demo cluster. These are the best instructions I could find: https://discuss.flyte.org/t/8490042/maybe-it-s-just-me-but-when-i-followed-https-docs-flyte-org- Hopefully that helps!

Ohh this is a good catch

ooooooooooo this is amazing, I'm going to try this right now!

Oh yes this only works with the demo! Glad you figured it out so quickly 🙂.

Ok so switched over to flytectl demo Able to push and pull a docker image to the local registry However, now the tasks just hang

task submitted to K8s

the

kubectl logs

seems to just show the task being run over and over Here's an extract of the messages on the sandbox-flyte-binary pod.

@nice-vr-73388 seems like you get an execution id. how does the execution looks in the UI?

Here's the overview of the execution in the UI, lmk if any other views are helpful! (note that I've done

docker image tag <http://ghcr.io/flyteorg/rawcontainers-shell:v2|ghcr.io/flyteorg/rawcontainers-shell:v2> localhost:30000/rawcontainers-shell:v2

& push, to get the example container on

localhost,

in case your wondering about that on the task pane)

cc @glamorous-carpet-83516 / @high-accountant-32689 (your code) - can you help here

Unfortunately, we do not ship copilot on the new sandbox (which essentially prevents raw containers from running). We took this route in order to minimize initialization time, but we should have an escape hatch in case users want to use copilot. Just to unblock you, an alternative is to use the old sandbox and make your containers publicly available (for example, by pushing them to your ghcr.io registry). Let me create a gh issue to track a way to enable copilot in the sandbox.

@high-accountant-32689 what do you mean we do not ship. It should pull it down automatically

Amazing! Thanks to you and Yee Hing Tong for getting this out! gratitude thank you gratitude thank you gratitude thank you Looking forward to giving it a spin after merge, and will update my article with changes as soon as it's ready.

Hey @nice-vr-73388 how are you using the dbt plugin can you share

yes - here's the code that fails for me nice to see the sql example, I have removed my comment about this potentially being a plugin wide issue.

from flytekitplugins.dbt.task import DBTRun
		from flytekitplugins.dbt.schema import DBTRunInput
		from flytekit.core.workflow import ImperativeWorkflow

		DBT_PROJECT_DIR = "."
		DBT_PROFILES_DIR = "."
		DBT_PROFILE = "bq-oauth"

		task1 = DBTRun(
		        name='model_a',
		        input=DBTRunInput(
		            project_dir = DBT_PROJECT_DIR,
		            profiles_dir = DBT_PROFILES_DIR,
		            profile = DBT_PROFILE,
		            select = 'model_a')
		    )
		task2 = DBTRun(
		        name='model_b',
		        input=DBTRunInput(
		            project_dir = DBT_PROJECT_DIR,
		            profiles_dir = DBT_PROFILES_DIR,
		            profile = DBT_PROFILE,
		            select = 'model_b')
		    )

		wb3 = ImperativeWorkflow(name='imperative_dbt_demo')

		task1_task_id = wb3.add_entity(task1)
		task2_task_id = wb3.add_entity(task2)

# Yields:
# `FlyteAssertion: Input was not specified for: input of type simple: STRUCT`

@nice-vr-73388 I found a bug in your code - refer to this example of dbt https://github.com/flyteorg/flytekit/blob/be24c52f3fb8f7949db172f490cca95fa0f0e413/plugins/flytekit-dbt/tests/test_task.py#L57

oh yes of course, that makes perfect sense. ok let me retry and correct my statements if so!

Ya it should work

Yup, your 100% correct, it's working now. Thanks for catching that! I'm going to update my statements and remove the bug i filed. TY!
