cannot run `apt-get update` while running `buildah bud` inside a container

[Masber]

Description we are trying to build a container image inside a container using buildah. The build process starts but then fails when we try to run apt-get update

error:

error running container: error from crun creating container for [/bin/sh -c apt-get update   && env DEBIAN_FRONTEND=noninteractive TZ=Europe/Zurich   apt-get -yqq install --no-install-recommends     build-essential     ca-certificates     curl     file     g++     gcc     gfortran     git     gnupg2     iproute2     lmod     locales     lua-posix     make     patch     python3     python3-pip     python3-setuptools     tcl     unzip     vim     less   && locale-gen en_US.UTF-8   && rm -Rf /var/lib/apt/lists/*]: creating cgroup directory `/sys/fs/cgroup/memory/buildah-buildah1277165473`: No such file or directory

Steps to reproduce the issue:

1. Install buildah in container image

   • apk add buildah
   • mkdir -p $HOME/.config/containers
   • echo "unqualified-search-registries = ['docker.io']" > $HOME/.config/containers/registries.conf
   • mount
   • id
   • env
   • buildah bud -f Dockerfile --format docker -t $IMAGE_NAME
   • buildah login -u $CSCS_REGISTRY_USER -p $CSCS_REGISTRY_PASSWORD $CSCS_REGISTRY
   • buildah push $IMAGE_NAME

2. Docker file FROM ubuntu:20.04

ARG SPACK_VER=0.17.0 ENV SPACK_ROOT=/opt/spack

This list corresponds mostly to the list from the spack dockerfile (share/spack/docker/ubuntu-1804.dockerfile)

ENV LANGUAGE en_US.UTF-8 ENV LANG en_US.UTF-8 ENV LC_ALL en_US.UTF-8

@Masber this smells like a crun issue in Ubuntu. I think 20.04 has crun included, but I'm not sure if it's the default. I don't have a way to check quickly, can you?

[Masber]

sorry, need to clarify this. So by crun, do you mean this https://github.com/containers/crun?

[nalind]

What sort of host is it? If it's using cgroups v1, and the container isn't privileged, it's not going to be able to create its own control groups. Try setting BUILDAH_ISOLATION=chroot or running it with --isolation chroot to have buildah use something that's more like chroot for handling RUN instructions, instead of attempting to run a proper container inside the container.
