Hello @Pearl1594 and @harikrishna-patnala. I'm opening this up as a draft PR
to get some feedback.
I'm implementing a very basic data source to read Virtual Machine (Instance)
resource, using the `instance_id` as an input in the terraform configuration
file. Once I have this working successfully, I'll write different filters to
extend its functionality and also remove all `log.Printf()` calls to make the
code cleaner.
So, at the moment, I am able to associate resource data with
`*schema.ResourceData`. This has been confirmed by running the `DEBUG` trace on
the Terraform configuration file (main.tf) but when I try to read instance data
using Terraform, the output block always returns `null`. I am trying to figure
out why is that the case. Could you also pleas etake a look and suggest
something?
I am attaching the main.tf and the logs I have captured.
From `main.tf`:
```
data "cloudstack_instance" "my_instance" {
instance_id="153aa39d-5f61-4cf8-8e17-687ee25807ff"
}
output "instance-output" {
value = "${data.cloudstack_instance.my_instance}"
}
```
`terraform apply` output:
```
