Build within container abruptly stops on current `devel` image

[David00]

Hi @guysoft,

I am in the process of moving my build environment to a new server, and this process has me chasing a strange issue that seems to be related to the current docker image.

Here are the steps to reproduce (make sure that you don't have a cached guysoft/custompios:devel docker image already!)

cd /tmp
git clone https://github.com/guysoft/CustomPiOS.git
cd CustomPiOS
./src/make_custom_pi_os -g test_distro

cd test_distro/src/

echo """version: '3.6'

services:
  custompios:
    image: guysoft/custompios:devel
    container_name: test_distro_builder
    tty: true
    restart: always
    privileged: true
    volumes:
      - ./:/distro
    devices:
      - /dev/loop-control""" >> docker-compose.yml

docker compose -f docker-compose.yml up -d

docker exec -it test_distro_builder build

As you can see, this is a 100% stock pull and implementation as described in the docs. The output above ends with the following lines:

+++++ git -C /CustomPiOS rev-parse HEAD
fatal: not a git repository (or any of the parent directories): .git
++++ BASE_COMMIT=
+ exit 1

I've tried to debug this through the various bash scripts but couldn't really figure it out. There are no error messages raised, and the git message that says fatal: not a git repository ... shows up in both the working build and the non working build. Something is calling exit 1.

Here's the full build.log.

This build is happening with the current devel image on amd64. Here's my docker image inspect output:
docker image inspect.txt

I noticed that my image SHA doesn't match the SHA shown on docker hub so that was kind of concerning too. The image where things are working fine was built on 9/9/2022, and has a docker image inspect that starts like:

[
    {
        "Id": "sha256:00fb8e40f27ca745780215286b06fd65e022d960c81e610bd59a741c7de64301",
        "RepoTags": [
            "guysoft/custompios:devel"
        ],
        "RepoDigests": [
            "guysoft/custompios@sha256:0c51743cc99289d9e1915735288672b3831be5f55c325ad7d70b96f2f1d1ee2a"
        ],
        "Parent": "",
        "Comment": "buildkit.dockerfile.v0",
        "Created": "2022-09-09T16:37:12.368800052Z",

Here is the build.log from the image described above, using the same exact setup steps I shared at the top of this issue (except I already have the old custompios:devel image.

Thanks!

Hey, its caused by a regression form #208
I am adding a workaround for now so it does build

[David00]

Thank you for the super quick response and fix! I just tested the new image and it's good to go now.

FYI bookrowm was released yesterday and is likely to break
