no partitions defined while using dind (docker in a docker) with gitlab ci runner

[marcelomanzo]

I am facing the same issue, while using gitlab ci runner, even when using: -v /dev:/dev
build_os_dist:
image: "docker:latest"
stage: .pre
services:

• docker:dind
  script:
• apk update
• apk add git
• git clone https://github.com/solo-io/packer-plugin-arm-image
• cd packer-plugin-arm-image
• docker run --rm --privileged -v /dev:/dev -v {PWD}/packer_cache:/build/packer_cache -v ${PWD}/output-arm-image:/build/output-arm-image ghcr.io/solo-io/packer-plugin-arm-image build samples/raspbian_golang.json

I faced the same problem. Make sure you are not overwriting any previously created images that may exist in the images directory. For me I created an Ubuntu 20.04 image and the next time I was creating an Ubuntu 22.04 Image but I forgot to save the .img to a different file which was causing this error. I make use of packer-variables to make it more automated.

Aha, this looks the same as my issue, so I don't think this is specific to DIND

In my case, running natively on an RPi (i.e. outside of Docker)

source "arm-image" "raspios" {
  iso_url      = "https://downloads.raspberrypi.org/raspios_lite_arm64/images/raspios_lite_arm64-2022-04-07/2022-04-04-raspios-bullseye-arm64-lite.img.xz"
  iso_checksum = "sha256:35f1d2f4105e01f4ca888ab4ced6912411e82a2539c53c9e4e6b795f25275a1f"
  target_image_size = 3222000000
}

arm-image.raspios: output will be in this color.

@shantanoo-desai's suggestion

Make sure you are not overwriting any previously created images that may exist in the images directory. For me I created an Ubuntu 20.04 image and the next time I was creating an Ubuntu 22.04 Image but I forgot to save the .img to a different file which was causing this error.

doesn't apply in my case, because I'm running this packer build from a completely fresh directory every time

Edit: scratch that, rebooting the host, command runs fine. But... now I know what I'm looking for, @marcelomanzo if you can post the output of losetup and I'll see if you have the same issue as me :)
