Cloudinit file inside terraform config file not working - linux

Question

I'm trying to run a cloudinit file by passing it in the terraform config file. The terraform apply command creates all the resources. But when i spin up the VM, none of the changes from the cloudinit are seen in the VM.
Here is the Cloudinit file with .tpl extension:
users:
- name: ansible
gecos: Ansible
sudo: ALL=(ALL) NOPASSWD:ALL
groups: [users, admin]
shell: /bin/bash
ssh_authorized_keys:
- ssh-rsa AAAAB3NzaC1.......
And here is the main.tf file:
data "template_file" "users_data" {
template = file("./sshPass.tpl")
}
data "template_cloudinit_config" "config" {
gzip = true
base64_encode = true
part {
content_type = "text/cloud-config"
content = data.template_file.users_data.rendered
}
resource "azurerm_linux_virtual_machine" "poc-vm" {
name = var.vm_name
resource_group_name = azurerm_resource_group.poc_rg.name
location = azurerm_resource_group.poc_rg.location
size = var.virtual_machine_size
admin_username = var.vm_username
network_interface_ids = [azurerm_network_interface.poc_nic_1.id]
admin_ssh_key {
username = var.vm_username
public_key = tls_private_key.poc_key.public_key_openssh
}
os_disk {
caching = var.disk_caching
storage_account_type = var.storage_type
}
source_image_reference {
publisher = var.image_publisher
offer = var.image_offer
sku = var.image_sku
version = var.image_version
}
user_data = data.template_cloudinit_config.config.rendered
}

Try this:
data "template_cloudinit_config" "config" {
gzip = true
base64_encode = true
part {
content_type = "text/cloud-config"
content = "${data.template_file.users_data.rendered}"
}
In this example I change this line content = data.template_file.users_data.rendered for this one content = "${data.template_file.users_data.rendered}"
Hope this helps!

Found the errors. Changed the extension to '.cfg.'. Added 'custom_data' instead of user_data.
Added '#cloud-config' to the 1st line of the file.
Made sure I removed any spaces at end of my ssh key.
And also felt like I was using the wrong ssh key to login the whole time.
But anyways those things helped me.
