Never understood the whole alpine thing. I would say most sysadmins doing docker stuff do not understand the concept of what is a libc and its variants to understand the consequences of their choices. Hell I work in embedded and have worked with ulibc or musl and have been bitten quite hard. Some calls not working as expected are loads of fun. All for a few MB, when it could be done just using a proper small base image like has been suggested above.
