Hi @nomadme thanks for creating the issue.
Are you running buildah inside a container ? I think its failing while performing unshare but first I'd suggest updating buildah to latest version.
and could you share more details about your environment like if its a container and logs with buildah --log-level=debug <your command>
I am suspecting missing privileges on your working environment but your release is showing misleading error message. So please share details with your attempt from a latest version.
Thank you for getting back on this @flouthoc.
Yes, it is running inside a container built from: https://catalog.redhat.com/software/containers/ubi8/openjdk-11/5dd6a4b45a13461646f677f4?tag=1.10-10.1638383051

Try docker run --security-opt seccomp=unconfined -it quay.io/buildah/stable:latest /bin/sh
Or better yet, use Podman. :^)
Docker default seccomp.json does not allow the unshare Syscall.
Thanks @rhatdan

Hi @nomadme and @clydet ,
Sorry for late reply.
I tried playing with docker and quay.io/buildah/stable:latest inside docker.
I think inside container buildah uses fuse-overlay rather than host kernel overlay so we would also need to mount /dev/fuse when running buildah inside docker.
Could you guys please try with following command. Following works for me.
sudo docker run -it --device /dev/fuse:rw --security-opt seccomp=unconfined --security-opt apparmor=unconfined quay.io/buildah/stable:latest /bin/sh

@flouthoc, You're a stud. That works for me locally. We're looking to use buildah in containers running in AWS' ECS via Fargate. According to AWS docs regarding devices:
Note If you are using tasks that use the Fargate launch type, the devices parameter is not supported.
Any idea how we might work around an environment that doesn't allow us access to host devices?
Thanks @flouthoc
For me, it still doesn't work. I'm on M1Pro chip.

Here is the other try with M1 chip specific run.
sudo docker run -it --device /dev/fuse:rw --security-opt seccomp=unconfined --security-opt apparmor=unconfined --platform linux/amd64 quay.io/buildah/stable:latest /bin/sh

@flouthoc, I Googled around a bit and saw this, which states:
Podman can use native overlay file system with the Linux kernel versions 5.13. Up until now, we have been using fuse-overlayfs. The kernel gained rootless support in the 5.11 kernel, but a bug prevented SELinux use with the file system; this bug was fixed in 5.13.
It looks like Fedora is backporting the fix into its 5.12 kernels, so users should be able to use it once they get access to the kernel.
I haven't found a fedora container with a kernel later than 5.10.47-linuxkit. Guessing for our use case we'll need to move away from Fargate as AWS docs seem to indicate support for host device exposure when favoring EC2 based services. 🤞
Do you think that there's any use in searching about for any RHEL derivative containers with a 5.13 kernel? If so please point me in the right direction.
@clydet
I think that would need a host kernel change. Afaik fargate locks you with a kernel so I am not sure if you could change it. Could you confirm if host kernel can be changed on ECS with fargate from AWS support. I think not.
I'd like to recommend using ECS with EC2 that should easily allow you use --device or change the kernel via using custom AMI whatever you like.
@nomadme could you please try with --platform linux/arm64/v8 or --platform linux/arm i think docker desktop is doing something with emulation not sure.

I ran into same issue when using AWS ECS with Fargate and it uses vfs as default storage layer and if I use flag --storage-driver vfs still the same result.
buildah --storage-driver vfs bud -t myimage:1.0 -f . Error during unshare(CLONE_NEWUSER): Operation not permitted time="2022-03-11T17:40:04Z" level=error msg="error parsing PID "": strconv.Atoi: parsing "": invalid syntax" time="2022-03-11T17:40:04Z" level=error msg="(unable to determine exit status)"
AWS Fargate version we use is 1.4.0 and it seems to be using containerd as container runtime. Use of EC2 instead of Fargate is an option but AWS folks seems to have managed it with kaniko: https://aws.amazon.com/blogs/containers/building-container-images-on-amazon-ecs-on-aws-fargate/ and I was wondering if anyone managed to get around this with buildah.
This works on my M1:
docker run -it -e _BUILDAH_STARTED_IN_USERNS="" -e BUILDAH_ISOLATION=chroot \
--security-opt seccomp=unconfined --security-opt label:disabled \
quay.io/buildah/stable:latest /bin/sh
However it's necessary to use vfs as the storage driver, e.g. : buildah bud --storage-driver vfs . For overlay, it's necessary to mount the device, e.g.:
docker run -it --device /dev/fuse:rw -e _BUILDAH_STARTED_IN_USERNS="" -e BUILDAH_ISOLATION=chroot \
--security-opt seccomp=unconfined --security-opt label:disabled \
quay.io/buildah/stable:latest /bin/sh
Interesting how everyone is using app armor on a RHEL based docker image instead of label:disabled for SELinux
