Docker build as a duplex stream. Pipe in a tar stream and pipe out the build output
npm install docker-build
var build = require('docker-build')
var fs = require('fs')
fs.createReadStream('a-tar-file-with-a-dockerfile.tar')
.pipe(build('my-new-image'))
.pipe(process.stdout)The above example will build a docker image from the input tarball and pipe the build output to stdout using docker running locally on port 2375.
var stream = build(tag, [options])options can contain the following:
{
version: 'v1.15', // API version string to use (defaults to 'v1.15')
host: '/var/run/docker.sock', // host to docker
cache: true, // whether or not to use docker fs cache (defaults to true)
quiet: false, // be quiet - defaults to false,
registry: conf, // add a registry config
remove: true, // automatically removes intermediate contaners (defaults to true)
forceremove: false, // always remove intermediate containers, even if the build fails (defaults to false)
buildArgs: { foo: 'bar' }, // Set build-time variables
cpuShares: 0, // CPU shares (relative weight)
cgroupParent: '/cgroup-parent/foobar', // Optional parent cgroup for the container
cpuPeriod: 0, // Limit the CPU CFS (Completely Fair Scheduler) period
cpuQuota: 0, // Limit the CPU CFS (Completely Fair Scheduler) quota
cpusetCpus: 0, // CPUs in which to allow execution (0-3, 0,1)
cpusetMems: 0, // MEMs in which to allow execution (0-3, 0,1)
dockerfile: 'Dockerfile', // Name of the Dockerfile
memory: 0, // Memory limit
memorySwap: 0, // Total memory (memory + swap), '-1' to disable swap
pull: false, // Always attempt to pull a newer version of the image
ulimits: [
{ name: 'core', soft: 0, hard: 0 }, // core file size (blocks)

] // ulimit options
}There is a command line too available as well
$ npm install -g docker-build
$ docker-build --help
Running docker-build some-image-tag will build current working directory
