docker-raw-stream

Decode/encode a docker raw stream

npm install docker-raw-stream

Usage

docker raw streams multiplexes stdout/stderr to a single stream

var raw = require('docker-raw-stream')
var request = require('request')
 
var decode = raw.decode()
 
// forward the output to stdio
decode.stdout.pipe(process.stdout)
decode.stderr.pipe(process.stderr)
 
var url = 'http://docker-host:2375/containers/f7f65a63a595/attach?stderr=1&stdout=1&stream=1'
request.post(url).pipe(decode)

You can also use it encode a stream to the docker raw stream format

var encode = raw.encode()
 
// forward stdin to the stdout channel
process.stdin.pipe(encode.stdout)
 
encode.pipe(someWritableStream)

Per default if you end either encode.stdout or encode.stderr the encode stream will end. If you want to have the encode stream be half open use raw.encode({halfOpen:true}). This will require both encode.stdout and encode.stderr to end before the encode stream ends.
