This image is based on Alpine Linux image, which is only a 5MB image, and contains glibc to enable proprietary projects compiled against glibc (e.g. OracleJDK, Anaconda) work on Alpine.
This image includes some quirks to make glibc work side by side with musl libc (default in Apline Linux). glibc packages for Alpine Linux are prepared by Andy Shinn and the releases are published in andyshinn/alpine-pkg-glibc github repo.
This image is intended to be a base image for your projects, so you may use it like this:
FROM catenae/alpine-glibc
COPY ./my_app /usr/local/bin/my_app$ docker build -t my_app .
