i m wondering if it falls to the responsibility of flyte to inform the image what you are basically like certainly you can embed the tag of the image into the image itself it s not the cleanest thing to do and we don t advocate doing this but it s at least possible

< 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

Is there anything which I could use to get this information

< 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

< Nada Saiyed> So what we are working on is Flyte backend plugins in python Our goal is to simply write a backend plugin in python like a `rest` api and make it available locally as well as when running in remote This would make your life to extend really easy

Nada Saiyed · Answer

< 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

Ketan (kumare3) · Answer

no it will be rendered string

Ketan (kumare3) · Answer

you will have to get it from the task template container image

Nada Saiyed · Answer

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

Ketan (kumare3) · Answer

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
