Buildah COPY failing with multi-stage build
by Adam Wisniewski 28 Jun '21

28 Jun '21

Hi, Not sure if this is a buildah issue or perhaps a Tekton/OpenShift Pipelines (which is driving my image build). I have a multi-stage Dockerfile that is used in my pipeline's buildah bud execution. Every time this runs, it fails at the first COPY step in the second stage: "COPY --from=compile --chown=1001:0 /work/shared /opt/ol/wlp/usr/shared/" The failure is: STEP 8: COPY --from=compile --chown=1001:0 /work/shared /opt/ol/wlp/usr/shared/ error building at STEP "COPY --from=compile --chown=1001:0 /work/shared /opt/ol/wlp/usr/shared/": error adding sources [/var/lib/containers/storage/vfs/dir/7fe077c619b975b762ece658cf195b868b1efb81db3c839abe2110f2858bf1a5/work/shared]: no items matching glob "/var/lib/containers/storage/vfs/dir/7fe077c619b975b762ece658cf195b868b1efb81db3c839abe2110f2858bf1a5/work/shared" copied (1 filtered out): no such file or directory level=error msg="exit status 125" This is the command being used to run the build: buildah --storage-driver=vfs bud '--label=io.openshift.build.commit.author=Adam Wisniewski' --label=io.openshift.build.commit.date=2021-06-07T23:43:59-04:00 --label= io.openshift.build.commit.id=2dd06bb00930b598c8956a73158df8856bbbff83 '--label=io.openshift.build.commit.message=update Dockerfile' --label=io.openshift.build.commit.ref=master --format=oci --tls-verify=false --no-cache -f ./Dockerfile -t image-registry.openshift-image-registry.svc:5000/cicd/test-webhook-app:master-2dd06bb00930b598c8956a73158df8856bbbff83 . The Dockerfile builds fine with Docker, so I'm assuming I'm either missing some buildah bud option to allow for this behavior, or perhaps there is an issue with my file system in my pipeline in OCP.... Thanks for any help!

Buildah v1.21.0 Release Announcement
by Tom Sweeney 16 Jun '21

16 Jun '21

Hi All, Buildah v1.21.0 is now available and we've just posted the Release Announcement with the details at: https://buildah.io/releases/2021/06/09/Buildah-version-v1.21.0.html. There's now a new --secret option for the bud command that let's you insert "secret" info into your container image such as a database password, yet not have it visible to anyone within the container. Also the "buildah manifest rm" command has been added to allow you to remove one ore more manifests from an image, and a lot of work under the covers to make the image operations faster and the code usable across the container projects. Plus a number of smaller fixes and improvements throughout. Thanks to the many contributors for their help and contributions! Best Wishes, t

What is the outlook for a buildah-remote feature?
by Dakota Clark 01 Jun '21

01 Jun '21

Hello all! This is my first time posting to a mailing list so if I do something uncouth please do let me know! Podman has podman-remote with the ability to connect to a remote host which is useful for those on Macintosh and Windows systems to make use of podman. Something similar for Buildah would be nice as well but from what I've seen in GitHub issues related to the topic, such a feature isn't planned which leads me to my question: are there no plans for something like a buildah-remote utility because it's not a priority/concern or because it's architecturally difficult to do even if it was a priority? If such a thing as buildah-remote would be possible, would there be any concerns around submitting patches? It seems like it would be kind of a big change if it were to be added by a third party so I'm not sure if the Buildah project would be eager for such contributions. This isn't a feature request, I'm not here to demand that anyone start building this for me if it's possible so don't worry about that. Dakota

Problems with building multi-arch images
by Jan Christian Grünhage 27 Apr '21

27 Apr '21

Hey there, I've been trying to get multi-arch images using buildah to work, but I can't seem to figure out how this is supposed to work. And to be honest, the documentation around that topic is a bit lacking too. From reading https://github.com/containers/buildah/issues/1590, I'm fairly certain I've got what I need, but it still doesn't seem to work. First and foremost, a quick recap about my enviroment: - I'm on an x86_64 machine - I'm running this on an up to date install of Void Linux - I've installed buildah from the main Void repos, at version 1.20.1 - I've also installed qemu-user-static, version 5.2.0 Here's my Dockerfile: ```Dockerfile FROM docker.io/alpine RUN arch ``` Now, when I try to build a multi-arch image, I thought I needed to do this: ```sh ➤ buildah bud --pull --manifest test --platform linux/amd64 . ➤ buildah bud --pull --manifest test --platform linux/arm64 . ``` The first image build goes fine, which is expected, as I'm on my native architecture. The second one fails like so: ``` STEP 2: RUN arch standard_init_linux.go:219: exec user process caused: exec format error error building at STEP "RUN arch": error while running runtime: exit status 1 ERRO exit status 1 ``` Am I missing anything obvious? To me it looks like even though I specified the architecture, I'm running this natively without qemu-user-static being involved. I've also tried looking through the `--debug` output, but that's quite verbose and doesn't contain `qemu` anywhere. I'd be very glad to get feedback here, what I'm missing. Thanks in advance :) -- JC

shell globing with buildah run
by mh 16 Feb '21

16 Feb '21

Hi all, the following buildah script gives me some trouble to understand how to do it best: --- image_id=$(buildah from quay.io/centos/centos:stream8) run="buildah run $image_id --" set -e # works fine $run bash -c 'ls -l /var/cache/* /var/log/*' # does not work since * is not expanded $run ls -l "/var/cache/*" "/var/log/*" # does not work correctly $run rm -rf /var/cache/* /var/log/* #neither does $run rm -rf "/var/cache/*" "/var/log/*" # this works $run bash -c 'rm -rf /var/cache/* /var/log/*' # as can be seen with $run bash -c 'ls -l /var/cache/ /var/log/' ----- I am wondering how to correctly do this? using bash -c ? to make sure the globbing is done within the container and not outside? best mh

merge last x layers
by Hendrik Haddorp 17 Jun '20

17 Jun '20

Hi, is there any way to merge the last x layers of an image? Like if I have an image with five layers I would like to merge that down to say three or four layers. I know that I can remove all layers by squishing the image but I would like to keep some base layers. thanks, Hendrik
