Terraform-provider-aws: aws_lb does not support all loadbalancer attributes

[ameir]

The aws_lb resource support access logs and deletion protection, but there are a few other attributes that are not exposed via this provider [0][1]. This resource exposes the two available attributes as top-level arguments, while, for example, CloudFormation asks for a list of attributes [2], which I think is more flexible, although maybe this resource tries to keep things similar to aws_elb.

I need to enable cross-zone load balancing and adjust the timeout, but this must currently be done out-of-band.

Affected Resource(s)

• aws_lb

Support for NLB cross-zone load balancing has been merged into master and will release with v1.11.0 of the AWS provider, likely in a week. It looks like @appilon and @mpilar will be working out HTTP/2 in a followup PR. 😄

Thanks for the hard work, everyone!

Hello,

In our tests:

• Creating an ALB with enable_http2 set to false does not work: it creates an ALB with the flag set to true. The state contains "enable_http2": "false".
• Modifying the value in the terraform code trigger the change up to AWS
• Modifying the value in AWS has no consequence: terraform does not attempt to fix that.

Terraform v0.11.2
+ provider.aws v1.11.0

We seem to be having exactly the same issue as @octplane is having. Should this ticket be re-opened or a new one created?

[appilon]

I've traced through the code and think I've found the issue, I should have a PR with a fix up soon

[appilon]

The bug appears to be a bit more elusive than I thought. Working on a fix. I have made a new issue to track progress.
