The point of the alpine image is to be as small as possible. Adding bash makes the image go from 70.7MB to 74.5MB. And nothing prevents you from adding it to your own image.

/cc @nodejs/docker thoughts?

Looks like I can still use

docker run -it node:alpine /bin/sh

But during this time I find envinfo can't run on node:alpine tabrindle/envinfo#81. Anything I am missing ?

Let's keep it small.
