Monitor services in azure - azure

Question

The error message is:
There are some problems with the configuration, described below. The Terraform configuration must be valid before initialization so that Terraform can determine which modules and providers need to be installed.
Here's what I'm doing:
Written a terraform script in azvm.tf to create a VM.
Defined the variables resourcegroup, location, and pub_key in the variables.tf file, and call those variables in the azvm.tf file using string interpolation syntax.
Created a VM with the following features:
a) Ubuntu 18.04 server
b) VM name : any custom name
c) Admin_username : Any custom name
d) disable password authentication
e) size : Standard DS1_v2
f) Allow traffic for ssh, http, https
g) use public ssh key generated in the above step
With help of vi command we created variables.tf file as:
variable "resourcegroup"
{
default = "user-pbtwiiiuofyu"
}
variable "location"
{
default = ["East US"]
}
variable "pub_key"
{
default = ["ssh-rsa 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 root#6badb6ae71d1"]
}
And vi command we created azvm.tf file as
az vm create -n Myuyuuy5Vm -g var.resourcegroup --ssh-key-values var.pub_key
We have another similar task but less easy in compare to it i.e.-
Write a terraform script in azmonitor.tf to create a storage account,
storage container, storage blob to monitor and send log reports
everyday.
Define the variables resourcegroup and location in the variables.tf
file, and call those variables in the azmonitor.tf file using string
interpolation syntax
variables.tf as-
variable "resourcegroup"
{
default = "user-pbtwiiiuofyu"
}
variable "location"
{
default = ["East US"]
}
azmonitor.tf we had created as-
provider "azurerm" {
features {}
}
resource "azurerm_resource_group" "example" {
name = var.resourcegroup
location = var.location
}
resource "azurerm_storage_account" "example" {
name = "sa123321123"
resource_group_name = azurerm_resource_group.example.name
location = azurerm_resource_group.location
sku = "Standard_LRS"
}
resource "azurerm_storage_container" "example" {
name = "sc123321123"
resource_group_name = azurerm_resource_group.example.name
account_key = azurerm_storage_account.eample.name
public_access = "blob"
}
resource "azurerm_storage_blob" "example" {
name = "sb123321123"
resource_group_name = azurerm_resource_group.example.name
account_key = azurerm_storage_account.eample.name
source = azurerm_storage_container.name
}

Answer 1

So as mentioned above, you're using a mix of Terraform and Az CLI here - this is not right. You should use one or the other.
It seems you've been tasked to create a Linux VM using Terraform. You need a 'main' Terraform file for your main code/terraform objects and then a 'variable' Terraform file for your variables. Technically, Terraform will flatten every Terraform file that are in the same directory when you do a Terraform init/plan - this means you could put everything in just one single .tf file.
However, for the purpose of the tutorial, it's a good practice to split both so they can be managed easily. This is the Terraform code that you would want to use - it will help you create a Linux VM.
For simplicity, I'm putting a sample here that links back to the variables in your variables.tf
terraform {
required_version = "= 0.14.10" //change this accordingly
required_providers {
azurerm = {
source = "hashicorp/azurerm"
version = "=2.55.0"
}
}
}
resource "azurerm_resource_group" "example" {
name = var.resourcegroup
location = var.location
}
resource "azurerm_virtual_network" "example" {
name = "example-network"
address_space = ["10.0.0.0/16"]
location = azurerm_resource_group.example.location
resource_group_name = azurerm_resource_group.example.name
}
resource "azurerm_subnet" "example" {
name = "internal"
resource_group_name = azurerm_resource_group.example.name
virtual_network_name = azurerm_virtual_network.example.name
address_prefixes = ["10.0.2.0/24"]
}
resource "azurerm_network_interface" "example" {
name = "example-nic"
location = azurerm_resource_group.example.location
resource_group_name = azurerm_resource_group.example.name
ip_configuration {
name = "internal"
subnet_id = azurerm_subnet.example.id
private_ip_address_allocation = "Dynamic"
}
}
resource "azurerm_linux_virtual_machine" "example" {
name = "example-machine"
resource_group_name = azurerm_resource_group.example.name
location = azurerm_resource_group.example.location
size = "Standard_DS1_v2"
admin_username = "Admin_username"
network_interface_ids = [
azurerm_network_interface.example.id,
]
admin_ssh_key {
username = "adminuser"
public_key = file("~/.ssh/id_rsa.pub") //put your public key here
}
os_disk {
caching = "ReadWrite"
storage_account_type = "Standard_LRS"
}
source_image_reference {
publisher = "Canonical"
offer = "UbuntuServer"
sku = "18.04-LTS"
version = "latest"
}
}
Once you're done with validating the code above, you'll need two more objects,
The azurerm_network_security_group that will help you create the rules to allow inbound connectivity to the VM
The azurerm_subnet_network_security_group_association that will help you attach the subnet to the NSG.
Once you have the complete code, then you can run a terraform init to initialise the modules, followed by terraform plan to verify your plan and finally terraform apply to deploy the VM.
For the blob part:
variable.tf
variable "resourcegroup" {
default = "user-pbtwiiiuofyu"
}
variable "location" {
default = "East US"
}
azmonitor.tf
provider "azurerm" {
features {}
}
resource "azurerm_resource_group" "example" {
name = var.resourcegroup
location = var.location
}
resource "azurerm_storage_account" "example" {
name = "examplestoracc"
resource_group_name = azurerm_resource_group.example.name
location = azurerm_resource_group.example.location
account_tier = "Standard"
account_replication_type = "LRS"
}
resource "azurerm_storage_container" "example" {
name = "content"
storage_account_name = azurerm_storage_account.example.name
container_access_type = "private"
}
resource "azurerm_storage_blob" "example" {
name = "my-awesome-content.zip"
storage_account_name = azurerm_storage_account.example.name
storage_container_name = azurerm_storage_container.example.name
type = "Block"
source = "./some-local-file.zip"
}
