buildah: buildah bud fails on RUN - go build

Description

Using the following Dockerfile, I am unable to get successfully run the buildah bud command:

# Run using --privileged
FROM quay.io/openshift-pipeline/buildah
ARG GIT_SOURCE="https://github.com/a-roberts/knative-helloworld"
ENV TLS_VERIFY="true"
ENV CONTEXT_PATH="/workspace/git-source"
ENV DOCKERFILE_PATH="/workspace/git-source/Dockerfile"
ENV TAG="testing"
WORKDIR ${CONTEXT_PATH}
# This is the above $GIT_SOURCE repo on my local
COPY git-source/ .
VOLUME "/var/lib/containers"
ENTRYPOINT ["/bin/sh", "-c", "buildah build-using-dockerfile --tls-verify=${TLS_VERIFY} --layers -f ${DOCKERFILE_PATH} -t ${TAG} -- ${CONTEXT_PATH}"]

The resulting log is:

I have gotten Kaniko to build this repository. Curious if this issue is regarding some flags I have no set properly to the buildah command. I have tried setting the $BUILDAH_ISOLATION env and the corresponding --isolation flag (saw on another issue that could do something). I have run this on my 3.11 OKD cluster and locally on macOS (although still through the quay images) and experience the same error.

Steps to reproduce the issue:

1. Build above Dockerfile
2. Run using --privileged
