writing to stdin

[jaredly]

If this is currently supported by dockerode, could you include a test / example of attaching to a container's stdin? And if it's not supported, what are the chances of that happening?

Thanks!

Check the "duplex" branch :)
But it needs to be tested.

Basically it uses a duplex stream encapsulating req and res. It was hacked in 5 mins.
Right now it is failling the test suite on image building and creation.

I will probably look into it this weekend, since I also need it for other issue. #2

cool. Right now I'm going with manual websockets. Unfortunately I can't get
websockets working w/ unix sockets :( but local tcp works great.

Yeah I've the same problem in here with ws and unixsocket.
I've open an issue websockets/ws#236 on their repo about this.

unfortunately, I think there's a docker issue too:

Would very much like to be able to do this as well. Could you also provide docks on consuming regular stdout streams? I'm having trouble passing in a duplex stream and getting output.

stdin attach via remote api is still in a limbo right now, till I figure out how to do it.

Could you detail your second question?

You can easily attach and separate stderr and stdout, example:
container.attach({stream: true, stdout: true, stderr: true, tty: false}, function(err, stream) {
container.modem.demuxStream(stream, process.stdout, process.stderr);
});

I figured out my issue - I'm a total stream novice, and didn't realize I needed to override stream._write to get any output.

[apocas]

No problem :)
BTW, Passthrough stream from streams2 is cool for that, since you don't need to override a lot of stuff :)

Regarding stdin attach a lot of people is having issues with it via plain remote api.
Via websockets theres the issue you read above.

So right now it's in limbo.

Fixed in #38

Awesome!
