# Build a docker image for nginx on Ubuntu 14.04LTS.
# Use phusion/baseimage as base image. To make your builds
# reproducible, make sure you lock down to a specific version, not
# to `latest`! See
# https://github.com/phusion/baseimage-docker/blob/master/Changelog.md
# for a list of version numbers.
