Hello, I am writing a custom flytekit plugin and I was wondering how can I retrieve the rendered image uri in

execute()

of a custom plugin, if i pass a templated value to

container_image

. E.g. is my task definition

@task(task_config=my_task_config, container_image="{{.image.img1.fqn }}:{{.image.img1.version}}"

I can see that the

container_image

is set as a property and if I retrieve it, I see it’s value is still a templated string. How can I get the actual rendered image uri for that task? (i.e. basically I want what this function returns)

Hi Nada Saiyed, thanks for asking your question, and we will get you an answer soon! Thanks for being patient!

what kind of a plugin are you writing? this is a flytekit plugin right? nothing on the backend?

Yes. A flytekit plugin

i see.

@Yee I need this rendered image uri to in-turn launch another aws service which would use this image. And, Yes, currently embedding the tag of the image into itself is how I am retrieving the image_uri, but it would be a useful feature if flyte exposes this information via an api call or in some metadata.config, essentially all the task-details that are shown in the Flyte UI

@Ketan (kumare3) could you take a look at this please?

@Nada Saiyed i think you will have to use the TaskTemplate plugin today. We are working on a whole new improved plugin system that will make this easy. If you are interested we would love to share the ideas with you (Spotify and Union are working on it together). But until then it has to be a TaskTemplate plugin. This is an exmple - https://github.com/flyteorg/flytekit/blob/ab9aa65c420afed1ec3b80e0d650fcee3d63852a[…]/plugins/flytekit-sqlalchemy/flytekitplugins/sqlalchemy/task.py

@Ketan (kumare3) even if I use

PythonCustomizedContainerTask

and I pass a templated string to

container_image

in the task definition of the plug-in, while initialization, the value will still be a templated string. Not a rendered image-uri if I am not wrong.?

no it will be rendered string

i see.. thanks a lot. i think for now i will keep fetching this image-uri from the embedded tag of the image into itself

Ok, ya expect q4 that we will have the out of core Plugins. Also I will have an rfc soon. This will make extensibility even better
