how to change the size of disk with Packer chroot builder?

[Rodrigue Chakode]

Hello,

Is it possible to change the default size of the device setup by Packer to build an image using chroot?

Indeed, it seems that the size is fixed to 2Gb and in my case the provisionning script installs tools that make the disk full (causing the failing of the build).

==> azure-chroot: No apport report written because the error message indicates a disk full error

Here is an extract of df -h

/dev/sdd1       2.0G  1.7G  320M  84% /mnt/packer-azure-chroot-disks/sdd

Thanks,

Rodrigue

I have never used Azure but maybe this is the option you are looking for?

Hi Richard,

Thanks for your help.

I tried that option (os_disk_size_gb), which shall be used with the option 'from_scratch' (I failed to understand values to provide for 'pre_mount_commands', also required in that case) :(

For amazon-chroot builder, there is an option ('root_volume_size' [1]) which seems close to what I'm expecting,  but it's not supported by azure-chroot builder

By the way, I gave up and switched towards azure-arm builder - - even if it's a a bit slower than azure-chroot.
