I created Azure VMSS and i want to use it in Azure DevOps pipelines.

ADO part works perfect but when i run task, i got an error:

Starting: TerraformInstaller

In my Azure VMSS repo i have a file:

# Prerequisites

sudo apt-get -y install zip
sudo apt-get -y install unzip

# Update the list of packages
sudo apt-get update

source /etc/os-release

# Download the Microsoft repository keys
wget -q https://packages.microsoft.com/config/ubuntu/$VERSION_ID/packages-microsoft-prod.deb

# Register the Microsoft repository keys
sudo dpkg -i packages-microsoft-prod.deb

# Delete the Microsoft repository keys file
rm packages-microsoft-prod.deb

# Update the list of packages after we added packages.microsoft.com
sudo apt-get update

# Install PowerShell
sudo apt-get install -y powershell

# Update the latest packages and make sure certs, curl, https transport, and related packages are updated.
sudo apt-get update
sudo apt-get install ca-certificates curl apt-transport-https lsb-release gnupg

# Download and install the Microsoft signing key.
curl -sL https://packages.microsoft.com/keys/microsoft.asc | 
    gpg --dearmor | 
    sudo tee /etc/apt/trusted.gpg.d/microsoft.asc.gpg > /dev/null

# Add the software repository of the Azure CLI.
AZ_REPO=$(lsb_release -cs)
echo "deb [arch=amd64] https://packages.microsoft.com/repos/azure-cli/ $AZ_REPO main" | 
    sudo tee /etc/apt/sources.list.d/azure-cli.list

# Update the repository information and install the azure-cli package.
sudo apt-get update
sudo apt-get install azure-cli

To install zip, unzip, Azure CLI and powershell. But it seems it does not work.

Here is my extension code:

resource "azurerm_linux_virtual_machine_scale_set" "vmss" {
  lifecycle {
    ignore_changes = [ 
      tags,
      instances
    ]
  }

  name                 = local.vmss_name
  resource_group_name  = local.rg_name
  location             = local.rg_location
  sku                  = local.vmss_sku_tier
  instances            = 2
  admin_username       = var.vmss_user
  admin_password       = var.vmss_password
  computer_name_prefix = "vm-"
  upgrade_mode         = "Manual"
  overprovision        = false
  disable_password_authentication = false

  automatic_instance_repair {
    enabled      = false
    grace_period = "PT30M"
  }

  scale_in {
    force_deletion_enabled = false
    rule                   = "Default"
  }

  source_image_reference {
    publisher = "Canonical"
    offer     = "0001-com-ubuntu-server-jammy"
    sku       = local.vmss_sku_name
    version   = "latest"
  }

  os_disk {
    storage_account_type = "Premium_LRS"
    caching              = "ReadWrite"
    disk_size_gb         = 127
  }
  
  network_interface {
    name    = local.vmss_nic_name
    primary = true

    ip_configuration {
      name      = local.vmss_ipconfig
      primary   = true
      subnet_id = data.azurerm_subnet.subnet.id
    }
  }

  depends_on = [
    azurerm_resource_group.rg
  ]
}


resource "azurerm_virtual_machine_scale_set_extension" "cloud_init" {
  name                         = "cloud-init"
  virtual_machine_scale_set_id = azurerm_linux_virtual_machine_scale_set.vmss.id
  publisher                    = "Microsoft.Azure.Extensions"
  type                         = "CustomScript"
  type_handler_version         = "2.0"

  settings = <<SETTINGS
    {
        "script": "${filebase64("cloud-init.sh")}"
    }
SETTINGS

  depends_on = [ azurerm_linux_virtual_machine_scale_set.vmss ]
}

Why my shell script is not executed when instance is getting up and zip/unzip is not installed? I have almost identical code for VMSS for windows with script:

resource "azurerm_virtual_machine_scale_set_extension" "cloud_init" {
  name                         = "cloud-init"
  virtual_machine_scale_set_id = azurerm_windows_virtual_machine_scale_set.vmss.id
  publisher                    = "Microsoft.Compute"
  type                         = "CustomScriptExtension"
  type_handler_version         = "1.9"

  settings = <<SETTINGS
  {
     "commandToExecute": "powershell -encodedCommand ${textencodebase64(file("cloud-init.ps1"), "UTF-16LE")}"
  }
  SETTINGS

  depends_on = [ azurerm_windows_virtual_machine_scale_set.vmss ]
}

And for windows VMSS, it works like a charm
