SYNOPSIS

$ dfpp Dockerfile.pre > Dockerfile

# Dockerfile Syntax:
INCLUDE ./Dockerfile.inc
INCLUDE http://path/to/Dockerfile.inc
INCLUDE ./Dockerfile.inc http://path/to/Dockerfile.inc

DESCRIPTION

dfpp was written to allow simple pre-processing of Dockerfiles to add capabilities currently unsupported by docker build.

INSTRUCTIONS

INCLUDE [MERGE] [FILTERS] [file|uri] ...

This will inline a file or uri into the Dockerfile being generated.

MERGE

When including multiple Dockerfile snippets this will attempt to merge common instructions. Currently only ENV, LABEL and RUN are merged, otherwise multiple instructions will be repeated. RUN instructions are merged with "&&" while other instructions are merged with a space.
