This should be named control_plane_ips to be picked up by default by the bootstrap gather.

Suggested change

	output "ip_addresses" {
	output "control_plane_ips" {

okay, will update

I recommend that you use the full splat operator rather than the legacy one.

Suggested change

	value = ibm_is_instance.master_node.*.primary_network_interface.0.primary_ipv4_address
	value = ibm_is_instance.master_node[*].primary_network_interface[0].primary_ipv4_address

AFAIK, those new variables shouldn't be also be declared within data/data/ibmcloud/variables-ibmcloud.tf data/data/ibmcloud/master/variables.tf & data/data/ibmcloud/bootstrap/variables.tf for consistency?

Best Regards.

[cjschaef]

@pamoedom I'm not sure TBH, as I thought I ran into errors when trying to declare them, or perhaps I need to declare them a certain way for outputs. Let me retry testing that here and get back.

[cjschaef]

@pamoedom I'll double check terraform formatting on the warning above (Value for undeclared variable), as adding them to outputs.tf initially causes failures during openshift-installer create cluster, since it expects an input value for those variables in variables.tf

Also, I don't see the other platforms specify the bootstrap_ip or master variable (different platforms do different things)
https://github.com/openshift/installer/search?p=1&q=bootstrap_ip

But I'm not knowledgeable enough with Terraform to know whether this warning is an issue or not yet.

[staebler]

I would not bother spending too much time on the errors as they are inconsequential at the moment. The installer pins the terraform version, so there is no concern that it will start to fail for a given OpenShift version due to terraform no longer supporting supplying a value for an undeclared variable. Many of the other platforms have similar warnings. We will likely clean this all up in 4.11.

With that said, if you want to resolve the warnings, you would need to declare "bootstrap_ip" in data/data/ibmcloud/master/variables.tf and both "bootstrap_ip" and "control_plane_ips" in data/data/ibmcloud/bootstrap/variables.tf. For the latter file, the variables would need to have a default declared since the values will only be preset during the destroy phase.
