Creo mi propio archivo docker con lo siguiente, y todo funciona bien:

 FROM ubuntu:latest apt-get update && apt-get upgrade -y RUN apt-get -y install libxml2-dev libxslt1-dev python-dev build-essential libssl-dev libffi-dev libxml2-dev libxslt1-dev zlib1g-dev python-pip python-setuptools python2.7 git tox

Ahora trato de cambiar a FROM alpine:3.3 , así que escribí lo siguiente

 FROM alpine:3.3 RUN apk add --no-cache libxml2-dev libxslt1-dev python-dev build-essential libssl-dev libffi-dev libxml2-dev libxslt1-dev zlib1g-dev python-pip python-setuptools python2.7 git tox

Pero me da lo siguiente:

 fetch http://dl-cdn.alpinelinux.org/alpine/v3.3/community/x86_64/APKINDEX.tar.gz ERROR: unsatisfiable constraints: build-essential (missing): required by: world[build-essential] libssl-dev (missing): required by: world[libssl-dev] libxslt1-dev (missing): required by: world[libxslt1-dev] python-pip (missing): required by: world[python-pip] python-setuptools (missing): required by: world[python-setuptools] python2.7 (missing): required by: world[python2.7] tox (missing): required by: world[tox] zlib1g-dev (missing): required by: world[zlib1g-dev]

cual puede ser la razon?
