Unable to set the System Disk size

[Marcus-James-Adams]

From my reading of the docs I need to set image_disk_mappings -> disk_size if i want a custom system disk size "disk_size (number) - Size of the system disk, in GB, values range:"

I'm setting it in packer as follows: "image_disk_mappings":[{"disk_size":256}], but this always creates a secondary data disk of 256GB leaving the system disk at 40GB, custom disk sizes work ok from the console. Is this something I am doing wrong? How can you set a custom system disk size in packer?

Hi @Marcus-James-Adams , thanks for submitting this issue. image_disk_mapping options is only applied to data disks. We may need another option to support system disk related properties. We'll support this as soon as possible.

Thanks, its a show stopper for me as our systems need bigger system disks. Is the following workaround possible? I Manually create my own custom image Base OS disk that's based on a 256GB disk and then if I run packer using that as the source image will the new images have 256GB disks? or will it try and revert to a 40GB?

Yes, it will do the trick.
