For running applications in production, Alpine Linux is harmful and should be avoided. Getting a smaller container image is not worth trading mucl for glibc.
To a Docker outsider, to me this implies that Alpine for testing and non-Alpine for production is not harmful. Is that right? Wasn't having a unified environment half the point of using Docker? Doesn't two different base systems just open you up to a load of headaches? If so, then isn't it more of a "Alpine Linux as a Docker base is harmful" situation?
