VM Sizes

[thepaulmacca]

I'm looking to use these scripts to create Ubuntu2004 and Windows2019 images for some VMSS agents, and was wondering for those who've done the same, what VM sizes you went for, or recommend?

I'm thinking of using Standard_D4s_v3 for Ubuntu, so I can take advantage of ephemeral OS disks due to the disk size, but I won't get away with those for Windows. What sizes have worked for you for Windows?

Any tips appreciated, thanks

Hello @thepaulmacca even I am trying to use these scripts to create Ubuntu2004 image, however, the same thing fails while executing

{
        "type": "shell",
        "scripts": [
            "{{template_dir}}/scripts/installers/complete-snap-setup.sh"
        ],
        "environment_vars": [
            "HELPER_SCRIPTS={{user `helper_script_folder`}}"
        ],
        "execute_command": "sudo sh -c '{{ .Vars }} {{ .Path }}'"
},

Error message says:

Spent quite time to diagnose the issue but couldn't. Any ideas why it is failing ?

ADO pipeline is hosted on Microsoft Hosted Agent : vmImage: 'windows-2019' which calls a PowerShell script Pack-Image.ps1 to create the image.

Appreciate any help here.
