Dockerfile-guru

The project aims to allow you to import external Dockerfiles.

getting started

you need to have a Dockerfile.template file in the current directory. For example, I have this Dockerfile:

IMPORT ../Dockerfile.master
IMPORT ../Documents/Dockerfile.master
EXPOSE 3000
CMD [ "npm", "start" ]

as you can see, we are importing other Dockerfiles using the import statement. After running dfg, you will see the Dockerfile generated with the external Dockerfiles included, as so:

FROM node:wheezy

# Create app directory
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

# Install app dependencies
COPY package.json /usr/src/app/
RUN apt-get update
RUN apt-get install -y build-essential g++
RUN npm install -g gulp
RUN npm install
RUN npm rebuild node-sass

# Bundle app source
COPY . /usr/src/app

#this is another master
#first line is where the master lives
EXPOSE 3000
CMD [ "npm", "start" ]

Installing

npm install -g dockerfile-guru

and run dfg to generate the Dockerfile.

Running the tests

npm test
