I wrote the correct terraform script for the requirement; and instances also created successfully; While printing instances name to output: task getting failed.
I tried with multiple output option:
output “kke_instance_names” {
value = [for instance in aws_instance.kke : instance.tags[“Name”]]
}
output “kke_instance_names” {
value = join(“\n”, [for instance in aws_instance.kke : instance.tags[“Name”]])
}
output “kke_instance_names” {
value = join(" ", [for instance in aws_instance.kke : instance.tags[“Name”]])
}
output “kke_instance_names” {
value = join(“,”, [for instance in aws_instance.kke : instance.tags[“Name”]])
}
Still task is getting failed…
Hi @nirdeshkumar02
You may need to wait until the instances are in running state.
If it still fails. You need to share the files.
@Santosh_KodeKloud tried the same but still failing. In which format we need to print instances name in output block is missing in the task.
