Base Image Structure

project/
   |
   |-- install.d/   # deployed in /scripts on target container
   |      |         # launch on docker image building process
   |      |         # XX-name.sh - low XX are run first
   |      |-- 00-util.sh
   |      |-- 40-fix.sh
   |
   |-- pre-init.d/  # deployed in /scripts on target container
   |      |         # launch on docker container running process
   |      |-- 50-example.sh
   |
   |-- build        # build docker image : ./build [TAG]
   |-- common.sh    # don't modify - sourced by main.sh to execute pre-init.d scripts first
   |-- install.sh   # don't modify - execute install.d scripts on docker building process
   |-- main.sh      # source common.sh then execute entry point instruction
   |-- util.sh      # sourced by common.sh

Extended Image Structure

project/
   |
   |-- install.d/
   |-- pre-init.d/
   |
   |-- build        # same as based image
   |-- main.sh      # source based common.sh then execute entry point instruction

Extended Image Dockerfile

in any case, keep that :

FROM $baseImage

MAINTAINER $author $url

ADD files.tar /scripts

RUN bash /scripts/install.sh

then define only EXPOSE VOLUME & ENV instructions

Building Process

build script archive project files in files.tar then execute the Docker build command.

./build [optionalTag]

no need to worry about pwd, docker repository and image name depends on directory structure. you can keep same build script in any project
