dockerfile-parse
Parse a Dockerfile into a POJO
install
$ npm install dockerfile-parse
usage
Take this Dockerfile for example:
FROM quarry/monnode
ADD . /srv/app
RUN cd /srv/app && npm install
RUN cd /srv/app && make build
WORKDIR /srv/app
VOLUME /srv/data
ADD /my/source /src/dest
EXPOSE 80
EXPOSE 9989
VOLUME /srv/data2
RUN cd /srv/app && make build2
ENTRYPOINT node index.js
Lets parse it into a JavaScript object to see what it says:
var fs = require('fs')
var parse = require('docker')
var dockerFile = fs.readFileSync(__dirname + '/Dockerfile', 'utf8')
var pojo = parse(dockerFile)
console.dir(pojo)
api
var pojo = parse(dockerFileString)
Return a parsed version of the string that is a Dockerfile contents.
The pojo will have array fields for the following statements:
- add -> {source:'', dest:''}
- expose
- volume
- run
