fix: add --security-opt label=disable to buildah from#113
Merged
Conversation
Replace 26 exit codes inherited from workshop.pl that are no longer used in the Python implementation with sequentially numbered UNAVAILABLE_N entries. Preserves numeric values to prevent reuse and maintain stable exit code semantics. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Prevents SELinux MCS category mismatch when buildah runs inside a podman container. Without this, the nested buildah container gets different MCS labels than the outer container, blocking access to /etc/resolv.conf and causing DNS resolution failures during image builds.
