feat: (IAC-1101) How to change the OS version of NFS Server/Jump Server

[TakeshiMifune]

Please tell me how to change the OS version of NFS Server/Jump Server.

https://github.com/sassoftware/viya4-iac-azure I am referring to the above site. It is assumed that a Viya environment will be constructed using the sample files under the "viya4-iac-azure/examples" folder. (Specifically, it is assumed that "sample-input.tfvars" will be used.)

With the current default values, I think the NFS Server/Jump Server will be created with "ubuntu 20_04-lts", but I would like to create it with the OS version "22_04-lts".

I think it is possible to change the OS version by updating some configuration files. If it is possible to change the OS version, could you please tell me which files need to be updated and where to update them?

Best Regards, Takeshi Mifune

To update the VM OS version you would need to update the variable os_offer and os_sku in the variables.tf file here: https://github.com/sassoftware/viya4-iac-azure/blob/main/modules/azurerm_vm/variables.tf

The updated values should be:

variable "os_offer" {
  description = "Specifies the offer of the image used to create the virtual machines. Changing this forces a new resource to be created."
  type        = string
  default     = "0001-com-ubuntu-server-jammy"
}

variable "os_sku" {
  description = "Specifies the SKU of the image used to create the virtual machines. Changing this forces a new resource to be created."
  type        = string
  default     = "22_04-lts-gen2"
}

Please Note: The OMS agent VM extension is not support for Ubuntu 22.04, and hence even though the terraform apply command would be complete successfully you will see failure in Portal on the resource group deployment. The OMS agent is in a deprecation path and will be retired on August 2024. The current recommendation from Microsoft is to migrate to the Azure Monitor Agent, which we are starting to explore.

Hello riragh,

Thank you for your response. Let me ask one additional question.

The OMS agent VM extension is not support for Ubuntu 22.04, and hence even though the terraform apply command would be complete successfully you will see failure in Portal on the resource group deployment.

I understand that Portal shows a failure when deploying a resource group, but am I correct in assuming that the failure is only shown and that deploying the resource group itself is not a problem？

Best regards, Takeshi

So far in my experience, the VM extension error does not affect the VM install. However, there won't be any logs captured if the VM runs into issues.
