Hello, looking for suggestion to avoid flytekit during registration and runtime as its a common problem amongst that our users face much the python dep conflict and looking for possibilities to lessen the issue. I know we can possibly do multiple registration/use multiple image, but that itself can add complexity as there needs to be more image built during CI and there has been past issues/challenges with fast-register where folder structure and packaged code on multi image in a single registration can override each images code. We can also use

ImageSpec

(which requires flytekit 1.8) but for users are on proto3 runtime, they are still using flytekit<1.3 and so its not an option. Questions around abstracting flytekit 1. is

ContainerTask

the only task that can allow specification of a image without flytekit? 2. For registration, is it possible to register without flytekit and flytectl alone? If there are any further suggestion around it please advice, thanks!

Hi @broad-train-34581, (1) You can specify

container_image

in the task decorator: https://docs.flyte.org/projects/cookbook/en/latest/auto_examples/customizing_dependencies/multi_images.html (2) You can register using the

flytectl register

command but you need to package up the code first using the

pyflyte package

command and that requires flytekit. You can use FlyteRemote to register the Flyte entities programmatically: https://docs.flyte.org/projects/flytekit/en/latest/design/control_plane.html#registering-entities.

does

container_image

needs to have flytekit installed?

No, you don't need flytekit. You can directly send image to the

container_image

param in the task decorator.

You can write the workflow as yaml and register using flytectl, but it won’t be easy
