This and a couple of other comments mention nscd, however, unless it's different on other distributions, nscd works via a unix socket. To make it work in containers, you need to explicitly mount it in from the host or run the nscd daemon inside the container. I'd be surprised if @brianwawok was doing that with their non-alpine containers and didn't realize it since it's so explicit That said, I believe Alpine does have a glibc package which only adds a few MB. So @brianwawok can at least still run Alpine for the image size benefits if musl is unimportant to them.
