# Build the ior binary inside a Rocky Linux 8 container and write it as
# ior.el8 to the repo root. The container image is built once and reused on
# subsequent runs. Mirrors scripts/build-with-docker.sh but targets Rocky 8
# so the produced binary runs on hosts with the older glibc shipped there.
#
# Usage:
# ./build-with-docker-el8.sh # build image + compile ior.el8
# ./build-with-docker-el8.sh --build # force rebuild of the Docker image
# ./build-with-docker-el8.sh --run # skip image build, only compile ior.el8
