Terraform: using terraform output and count > 1

[sramakr]

I want use terraform output when provisioning multiple servers ( using count > 1 ) on openstack.

i believe it's looking for hardcoded name , and it's not working correctly. Is there any option to specify regex or any other ways ?

My config files

resource "openstack_compute_instance_v2" "test_server2" {
name = "tf-test3"
region = "${var.region}"
image_id = "${var.image_id}"
flavor_id = "${var.flavor_id}"
metadata {
this = "that"
}
key_pair = "${var.key_pair}"
security_groups = ["daas_ssh"]
count="${var.count}"
}

output "ip" {
value = "${openstack_compute_instance_v2.test_server2.access_ip_v4}"
}

Appreciate any help.

Thanks
Sriram

Someone was having a similar issue here #3362, let me know if my explanation there helps.

perfect works.

for reference,

resource "openstack_compute_instance_v2" "test_server2" {
name = "tf-test3"
region = "${var.region}"
image_id = "${var.image_id}"
flavor_id = "${var.flavor_id}"
metadata {
this = "that"
}
key_pair = "${var.key_pair}"
security_groups = ["daas_ssh"]
count="${var.count}"
}

output "ip" {
value = "${join(",",openstack_compute_instance_v2.test_server2.*.access_ip_v4)}"
}

Seems like the question is answered here, but I wonder if there's something to be added to the docs here given that two different people were tripped up by this already.

There is documentation here

Maybe adding another example along these lines would be nice.
