Parse a Dockerfile into a POJO
npm install dockerfile-parsedockerfile-parse
================
Parse a Dockerfile into a POJO
``
$ npm install dockerfile-parse
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:
`js
var fs = require('fs')
var parse = require('docker')
var dockerFile = fs.readFileSync(__dirname + '/Dockerfile', 'utf8')
var pojo = parse(dockerFile)
console.dir(pojo)
/*
{
from:'quarry/monnode',
workdir:'/srv/app',
entrypoint:'node index.js',
add:[{
source:'.',
dest:'/srv/app'
}, {
source:'/my/source',
dest:'/src/dest'
}],
expose:[80, 9989],
volume:['/srv/data', '/srv/data2'],
run:[
'cd /srv/app && npm install',
'cd /srv/app && make build',
'cd /srv/app && make build2'
]
}
*/
``
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
