Debug Output

Error: Your query returned no results. Please change your search criteria and try again.

  on modules/ec2/main.tf line 57, in data "aws_instances" "read-ec2":
  57: data "aws_instances" "read-ec2" {

Panic Output

Expected Behavior

I need to place a list of EC2 instances for the load balancer. Instead of creating instance by instance, I'm using count for the creation. For getting the list of instances created, I'm using data aws_instance, for getting the list of EC2 that were created.

Actual Behavior

At the moment of doing plan/apply I'm getting the error that the query return no results

Steps to Reproduce

Create multiple EC2 instances with the tags above, then execute a data provider to pull back the info.

1. terraform apply
