Hi Zack,

Can you share what steps 2 and 3 are in the build process?  Just at first blush, this looks like some kind of authentication error that jenkins is throwing.  Are you running the buildah commands from root or as a non-root user.  The other thought is to try what I call "decomposing" the Dockerfile.  Rather than trying to create the image using the Dockerfile, create it using buildah commands:

buildah from jenkins/jenkins:2.176.2-alpine
buildah copy  jenkins-working-container ./test_pub_key.pub /var/jenkins_home
buildah commit jenkins-working-container my-jenkins

That might shed some light on what's going on too.
