Dockerfile

#
# Docker file for CUBE image
#
# Build production image:
#
#   docker build -t <name> .
#
# For example if building a local production image:
#
#   docker build -t local/chris .
#
# Build development image:
#
#   docker build --build-arg ENVIRONMENT=local -t <name>:<tag> .
#
# For example if building a local development image:
#
#   docker build --build-arg ENVIRONMENT=local -t local/chris:dev .
#
# In the case of a proxy (located at say proxy.tch.harvard.edu:3128), do:
#
#    export PROXY="http://proxy.tch.harvard.edu:3128"
#
# then add to any of the previous build commands:
#
#    --build-arg http_proxy=${PROXY}
#
# For example if building a local development image:
#
# docker build --build-arg http_proxy=${PROXY} --build-arg ENVIRONMENT=local -t local/chris:dev .
