"error: Error -1 running transaction" while running Dockerfile as unprivileged user #9733

/kind bug

Description

I routinely build container images for my operator (https://github.com/openshift-kni/performance-addon-operators/) as unprivileged user on my fedora 33 (stock podman/containers packages). One of these containers (must-gather) wants to install RPMs into a ubi (https://www.redhat.com/en/blog/introducing-red-hat-universal-base-image) base image. Lately the process fails with

podman build --no-cache -f openshift-ci/Dockerfile.must-gather -t """quay.io"/"openshift-kni"/"performance-addon-operator-must-gather":"4.8-snapshot""" --build-arg BIN_DIR="build/_output/bin/" .
STEP 1: FROM quay.io/openshift/origin-must-gather:4.7.0 AS builder
--> e9ca204d2bb
STEP 2: FROM registry.access.redhat.com/ubi8/ubi-minimal:latest
STEP 3: RUN microdnf install -y shadow-utils

Can't pinpoint the failure to a specific update. No changes into the Dockerfile:

# rename to be consistent with all other must-gather helper
COPY ${BIN_DIR}gather-sysinfo /usr/bin/gather_sysinfo

ENTRYPOINT /usr/bin/gather

No changes into the user config

Steps to reproduce the issue:

  1. Run the following on a up-to-date fedora 33 with all the container stack packages from official repos
  2. Fetch a copy of https://github.com/openshift-kni/performance-addon-operators
  3. [OPTIONALLY] checkout this PR to further narrow down the problem https://github.com/openshift-kni/performance-addon-operators/pull/582
  4. run as unprivileged user make && make must-gather-container

Describe the results you received: container build fails as shown below

Describe the results you expected: container build succeds, or at very least the error message helps me understand the actual issue?

Additional information you deem important (e.g. issue happens only occasionally):

  1. disabling selinux (setenforce 0) has NO effect (build still fails)
  2. running as root works as expected!
  3. If I do podman run -ti registry.access.redhat.com/ubi8/ubi-minimal:latest -- /bin/bash and then microdnf install -y shadow-utils everything works as expected

Have you tested with the latest version of Podman and have you checked the Podman Troubleshooting Guide?

latest version - tested the latest packaged version troubleshooting guide - yes, not sure if uidmap is related, didn't change a thing. podman system migrate didn't help

Additional environment details (AWS, VirtualBox, physical, etc.): this happens on a up to date fedora 33

giuseppe commented 3 years ago

shadow-utils use xattrs, I think it can be a kernel regression.

Could you try the reproducer here: https://github.com/containers/buildah/issues/3071#issuecomment-796070354 ?

usage: setcap [-h] [-q] [-v] [-n <rootid>] (-r|-|<caps>) <filename> [ ... (-r|-|<capsN>) <filenameN> ]

 Note <filename> must be a regular (non-symlink) file.
 -r          remove capability from file
 -           read capability text from stdin
 <capsN>     cap_from_text(3) formatted file capability

 -n <rootid> write a user namespace limited capability
 --license   display the license info

so IIUC it fails like on F34 and so it seems a regression, or at least a breaking change indeed. Not sure if relevant: both my /home and /tmp fs are ext4.

giuseppe commented 3 years ago

yes, it is a regression in the kernel and we cannot do anything about it.

The only workaround I am aware of is to specify a different mapping:

podman build --userns-uid-map 0:1:65535 --userns-gid-map 0:1:65535 ....

Does it work for you?

I am closing the issue because it is not a bug in Podman/Buildah that we can address, but we discuss the problem further here

ffromani commented 3 years ago

thanks @giuseppe , makes sense and I agree to close this issue.

TomSweeneyRedHat commented 3 years ago

@fatherlinux FYI issue running ubi image

MarSik commented 3 years ago

If this is a kernel regression, do you maybe have a link to a proper Fedora bug? I would prefer if this blocked the F34 release :)

we only had a discussion here: https://github.com/containers/buildah/issues/3071

I am not aware of any bugzilla to track it
