Fix: Allow setting metadata endpoint options so users can configure or disable

[scotthesterberg]

Can we get this fix back-ported to this repo: aws-ia/terraform-aws-eks-blueprints#657 ? It would be useful for the same reasons it was implemented for the AWS EKS Blueprints repo.

Allow setting metadata endpoint options so users can configure or disable.

Motivation

Allow users to configure the metadata endpoint options to suit their workloads, or even disable if not supported in their region

This is already supported in this module

[scotthesterberg]

I do not believe it is. There is currently no way to fully disable setting the metadata_options. I have attempted setting metadata_options = null and Terraform still attempts to set the metadata. In some AWS deployments this is not currently supported. This is why the enable_metadata_options flag was implemented in the referenced PR.

do you have a reproduction I can look at

[bryantbiggs]

after investigating, it looks like our conditional check against null is incorrect. PR coming soon

[scotthesterberg]

Awesome, thank you so much!

@scotthesterberg this should be resolved now by setting metadata_options = {} , let me know if you run into any issues
