Not able to build custom rancher raw: install2disk missing

[tech509201941]

I try to build a custom rancher raw as described here in the official rancher docs:

https://rancher.com/docs/os/v1.2/en/custom-builds/custom-rancheros-iso/

Unfortunately, I am not able to successfully address this step over here:

packer build gce-qemu.json

Results in:

qemu-googlecompute output will be in this color.

1 error(s) occurred:

* Bad script '../scripts/install2disk': stat ../scripts/install2disk: no such file or directory

Where do I get this ../scripts/install2disk'? I can't find it in the repo: https://github.com/rancher/os/tree/master/scripts

Thanks a lot :)

Thanks for your support. Unfortunately, I am now blocked by this error:

RANCHEROS_VERSION=v1.4.2 make test-build

Resulting in:

AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY must be set

How can I get the image as file?

I don't want to directly deploy to AWS or something like that. Thanks a lot :)

If you want to build a GCE image, try this: PACKER_BOOT_WAIT=90s RANCHEROS_VERSION=vX.Y.Z make build-gce

Thank you for your support @niusmallnan :)

I tried with: PACKER_BOOT_WAIT=90s RANCHEROS_VERSION=v1.4.2 make build-gce

but it fails at this step:

Is anyone able to investigate what is missing? Thanks a lot :)

Missing logs, I cannot see the key errors.

However, there is one point to confirm that your host needs to support KVM.

[tech509201941]

@niusmallnan 👍

I process the build on the newest version of macOS and I have installed QEMU via brew to enable support KVM. Is this sufficient?

Here is the full log at the step where it fails:

It seems like that KVM is not enabled on your setup.

@niusmallnan

Thanks a lot this was my mistake :)

Do you have a idea on how to build a QCOW2 (QEMU Emulator) image or respectively is there an official way to accomplish this?

[niusmallnan]

You can refer to this script: https://github.com/rancher/os-packer/blob/master/cloudstack/cloudstack-qemu.json
