Is there a way to use the built image for azure containerapps job in bicep?

[codars]

Using azure.yaml I can define the docker image to be built and used for a service, but what I want to do is to deploy an azure containerapps job that uses the latest built image, I don't find such a way to achieve this, anyone can help?

What I'm doing now:

In my main.bicep:

...
param imageName string = 'blablabla:azd-deploy-172930129'

...
module jobCron 'app/cron.bicep' = {
   ...
   containerImageName: imageName
}

But this means after I change the code, I'll need to first commit the change, deploy it, get the image tag, and then update the main.bicep again just to modify the image tag.

This is annoying, is there a better way to allow the job to use image from latest docker image built?

Try tagging the image name with :latest instead of the version.
