deploying containers to Azure via Terraform - best practice to build custom image and use it in azure container group

Question

By now I am researching, how I could move my infrastructure to Azure using terraform. Where I am stuck by now is the following scenario: I have a docker image, that uses the copy command to add some files into it. One solution I could think of is that I first build this Image using docker, push it to azure registry and then using it as container inside the azrerm_container_group resource. Using the kreuzwerker/docker provider I could also just use the dockerfile, but could not find a equivalent solution in Azure. So, what would be your suggestions? Thanks in Advance!

the base for azure is:

resource "azurerm_container_group" "containers" {
  name                = "xxx"
  location            = xxx
  resource_group_name = xxx
  ip_address_type     = "Public"
  os_type             = "Linux"

  container {
    name   = "xxx"
    image  = "xx/xx:latest"
    cpu    = "1"
    memory = "1.5"

I tried in my environment with below code.

Check the name of the image given while pushing docker image to the registry.
Usually it will be pushed to dockerhub.
To push an image to Microsoft Container Registry add or prepend mcr.microsoft.com/ to the name of your container registry.

Push to the microsoft container registry

Code:

provider "docker" {
 # host = azurerm_container_registry.acr.login_server
  registry_auth {
    address  = azurerm_container_registry.acr.login_server
    username = azurerm_container_registry.acr.admin_username
    password = azurerm_container_registry.acr.admin_password
  }
}



resource "docker_registry_image" "helloworld" {
  name = "mcr.microsoft.com/azuredocs/aci-helloworld:latest"

  build {
    context    = "${path.cwd}/absolutePathToContextFolder"
    dockerfile = "Dockerfile"
  }
   
 }

and then try to store/use in the container group.

resource "azurerm_container_group" "example" {
  name                = "kaexample-container"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name
  ip_address_type     = "Public"
  dns_name_label      = "kavyaaci-label"
  os_type             = "Linux"

  container {
    name   = "hello-world"
    image  = "mcr.microsoft.com/azuredocs/aci-helloworld:latest"
    cpu    = "0.5"
    memory = "1.5"

    ports {
      port     = 443
      protocol = "TCP"
    }
  }

  tags = {
    environment = "testing"
  }
}

providers.tf

terraform {
  required_providers {
 

    azapi = {
      source  = "azure/azapi"
      version = "=0.1.0"
    }

    azurerm = {
      source  = "hashicorp/azurerm"
      version = "=3.0.2"   
    }

    docker = {
      source  = "kreuzwerker/docker"
      version = ">= 2.16.0"
    }
}

Code executed:

terraform apply
