Terraform Version and Provider Version

Terraform v1.6.6
on darwin_arm64

• provider registry.terraform.io/hashicorp/cloudinit v2.3.4
• provider registry.terraform.io/oracle/oci v6.7.0

Affected Resource(s)

modules/workers

Expected Behavior

When creating node pools with modules/workers, and managing cloudinit with "cloud_init" input variable, any further changes applied to cloudinit should be automatically applied to node pool and newly created nodes should inherit from the latest cloudinit changes.

Actual Behavior

Newly created nodes after applying changes on cloudinit do not inherit from those changes.

Steps to Reproduce

1. setup node pool with cloudinit configured
2. create node on that pool
3. change cloudinit and apply changes
4. drop the old node and create new one
   => the new node would not get latest cloudinit changes.

Seems linked to this ignore_changes config : https://github.com/oracle-terraform-modules/terraform-oci-oke/blob/46ec5f4f8464b209f1248bcbacf89f342c269d8f/modules/workers/nodepools.tf#L277C1-L278C1
Tested removing this line, applied the changes, and it worked like a charm:
