What's the use case for this?

[namnguyen-tmr]

We have a use case where we want to disable IMDS service, .i.e set AWS_EC2_METADATA_DISABLED to true. Can we add support for this please

[stijndehaes]

We set the KUBERNETES_SERVICE_HOST to the AWS URL instaed of using the internal service, this improves reliability because at some point we were seeing issues with the internal service.

env:
- name: KUBERNETES_SERVICE_HOST
  value: ${var.kubernetes_host}

@simonmarty Any timeline for this to be merged and released?
