A glibc binary package builder in Docker. Produces a glibc binary package that can be imported into a rootfs to run applications dynamically linked against glibc.

Build a glibc package based on version 2.27 with a prefix of /usr/glibc-compat:

docker run --rm -e STDOUT=1 sgerrand/glibc-builder 2.27 /usr/glibc-compat > glibc-bin.tar.gz

You can also keep the container around and copy out the resulting file:

docker run --name glibc-binary sgerrand/glibc-builder 2.27 /usr/glibc-compat
docker cp glibc-binary:/glibc-bin-2.27.tar.gz ./
docker rm glibc-binary
