Dockerfile

FROM amazonlinux:1
MAINTAINER William O'Neill

# The Amazon Linux Docker image doesn't contain all of the packages that the EC2
# instance starts with. This script installs the missing packages only when
# building a docker image

# List was generated by comparing the output of
#   docker run -it --rm amazonlinux:latest rpm --queryformat "%{NAME}\n" -qa | sort
# and
#   TODO: a kludged terraform that spins up an EC2 instance
# Note that putting both outputs into a file and running `comm -23 file_a file_b` helps!
