Hi @Varma If you want to create a standalone managed image from version "1.0.1" of an image in the Compute Gallery, you would typically do this by deploying a VM from the gallery image and then capturing that VM as a managed image. This process allows you to preserve the software and configuration from "1.0.1" (and by extension, anything inherited from "1.0.0") in a new managed image. This new managed image can then be used to deploy new VMs, containing all the software and configurations from the "1.0.1" version, and if applicable, And it can be called "1.0.2"

Hi Jackson,

Thank you

Could you please clarify my following follow up questions

suppose like wise I have 10 images in gallery so if 10th image that all previous version right?

( if image is created from previous version )

is there any way to back up compute gallery ?

after creating Managed image with steps deployment of vm and capture VM, can we use that managed image name in the following

Packer template ?

packer
required_plugins {
azure = {
version = ">= 1.0.0"
source = "github.com/hashicorp/azure"
}
}
}

source "azure-arm" "example" {
managed_image_name = "test-ubuntu-20.04img-${formatdate("DD-MMM-YYYY-hh-mm-ss", timestamp())}" managed_image_resource_group_name = var.gallery_resource_group
managed_image_storage_account_type = "Standard_LRS"
location = var.location

# Using Azure CLI for authentication
use_azure_cli_auth = true

image_offer = "0001-com-ubuntu-server-focal"
image_publisher = "Canonical"
image_sku = "20_04-lts-gen2"

os_type = "Linux"
vm_size = "Standard_B4ms"
os_disk_size_gb = 64

shared_image_gallery_destination {
resource_group = var.gallery_resource_group
gallery_name = var.gallery_name
image_name = "test-ubuntu-20.04"
image_version = "1.0.0"
replication_regions = ["uaenorth"]
storage_account_type = "Standard_LRS"
}
}

build {
sources = [
"source.azure-arm.example"
]

provisioner "shell" {
execute_command = "chmod +x {{ .Path }}; sudo {{ .Vars }} {{ .Path }}"
script = "install.sh"
}
}

4.

so above code you can see shared image Gallery section there we can give compute gallery details I have mention in my first comment, am I correct? ( for new image to be created )

5.

while creating which is place best store that managed image? Is it market place or storage account ?

@varma

Answer:
Yes! the 10th image would include all the updates and configurations of the previous versions, ssuming each new version builds upon the last

is there any way to back up compute gallery ?

No, Azure Compute Gallery itself does not offer a direct "backup" feature

after creating Managed image with steps deployment of vm and capture VM, can we use that managed image name in the following Packer template ?
Yes, you can use a managed image name in a Packer template as part of your source configuration.

Hi Jackson. Just quick question, I have created managed image from custom image present in image gallery from azure. you can see below

and in terraform we call above managed image as a azurerm shared image , am i correct? ( i highlighted below)
Jackson Martins 10,606 Reputation points MVP Volunteer Moderator

Yes! is used to set a reference to an image stored in a Shared Image Gallery in Azure

You will define the resource group and shared image gallery using azurerm_resource_group and azurerm_shared_image_gallery respectively. The image definition is created with azurerm_shared_image, where you will specify the name, gallery, and location, among other parameters.

HI Jackson

1,

Just double checking

so managed image in azure nothing but azurerm_share_image in terraform , is this correct statement?

2.

I created the HCL template, resource group name is "cg" , while creating managed image I gave same resource group name "cg" where computer gallery resource also there. so now you can see below HCL template , i know it might be out of scope , but since you have already worked if you could provide quick suggestion that would be great, my question, did I provide source image details and destination computer gallery details correctly? Please clarify

packer 
  required_plugins {
    azure = {
      version = ">= 1.0.0"
      source  = "github.com/hashicorp/azure"
    }
  }
}

source "azure-arm" "example" {
  managed_image_name                 = "MT-Image"
     managed_image_resource_group_name  = cg

  location                           = eastus

  # Using Azure CLI for authentication
  use_azure_cli_auth = true

  image_offer     = "visualstudio2022"
  image_publisher = "microsoftvisualstudio"
  image_sku       = "20_04-lts-gen2"

  os_type         = "Windows"
  vm_size         = "Standard E2bds v5"
  os_disk_size_gb = 64

  shared_image_gallery_destination {
    resource_group       = cg
    gallery_name         = gallery1
    image_name           = "newimage"
    image_version        = "1.0.1"
    replication_regions  = ["eastus"]
    storage_account_type = "Standard_LRS"
  }
}

build {
  sources = [
    "source.azure-arm.example"
  ]
 provisioner "powershell" {
    inline = ["Remove-WindowsFeature Web-Server", "while ((Get-Service RdAgent).Status -ne 'Running') { Start-Sleep -s 5 }", "while ((Get-Service WindowsAzureGuestAgent).Status -ne 'Running') { Start-Sleep -s 5 }", "& $env:SystemRoot\\System32\\Sysprep\\Sysprep.exe /oobe /generalize /quiet /quit", "while($true) { $imageState = Get-ItemProperty HKLM:\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Setup\\State | Select ImageState; if($imageState.ImageState -ne 'IMAGE_STATE_GENERALIZE_RESEAL_TO_OOBE') { Write-Output $imageState.ImageState; Start-Sleep -s 10  } else { break } }"]
  }

}

and here is the magened image and compter gallery details from azure:

Hi Varma, try to do this:

Resource group and location strings: Put the resource group name cg and location eastus in quotes to ensure they are recognized as strings. VM Size Fix: Adjust VM size from Standard E2bds v5 to Standard_E2b_v5 to match Azure naming conventions for VM sizes.

Here`s the sample:
packer {

  required_plugins {
    azure = {
      version = ">= 1.0.0"
      source  = "github.com/hashicorp/azure"
    }
  }
}
source "azure-arm" "example" {
  managed_image_name                 = "MT-Image"
  managed_image_resource_group_name  = "cg"
  location                           = "eastus"
  # Using Azure CLI for authentication
  use_azure_cli_auth = true
  image_offer     = "visualstudio2022"
  image_publisher = "microsoftvisualstudio"
  image_sku       = "20_04-lts-gen2"
  os_type         = "Windows"
  vm_size         = "Standard_E2b_v5"
  os_disk_size_gb = 64
  shared_image_gallery_destination {
    resource_group       = "cg"
    gallery_name         = "gallery1"
    image_name           = "newimage"
    image_version        = "1.0.1"
    replication_regions  = ["eastus"]
    storage_account_type = "Standard_LRS"
  }
}
build {
  sources = [
    "source.azure-arm.example"
  ]
  provisioner "powershell" {
    inline = [
      "Remove-WindowsFeature Web-Server",
      "while ((Get-Service RdAgent).Status -ne 'Running') { Start-Sleep -s 5 }",
      "while ((Get-Service WindowsAzureGuestAgent).Status -ne 'Running') { Start-Sleep -s 5 }",
      "& $env:SystemRoot\\System32\\Sysprep\\Sysprep.exe /oobe /generalize /quiet /quit",
      "while($true) { $imageState = Get-ItemProperty HKLM:\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Setup\\State | Select ImageState; if($imageState.ImageState -ne 'IMAGE_STATE_GENERALIZE_RESEAL_TO_OOBE') { Write-Output $imageState.ImageState; Start-Sleep -s 10  } else { break } }"
    ]
  }
}
