Is there a way to modify elastic beanstalk target group through IaC?

[obreo]

I'm trying to connect Elastic beanstalk environment with a shared application load balancer through Terraform.

By default, the load balancer's listener does not recognise the EB's target group, which requures me to modify the load balancer manually to avoid 503 error.

I want to solve this using IaC. I am using terraform.

I think this can be solved by specifying the target group for EB to use the one created by the load balancer - using EB namespace environments.

Or by letting the ALB listener to point the EB target group.

I couldn't find a way to do that. I'm not sure if this is not supported or there is a workaround to solve it.

Can you guide me in this?
