exec streaming does not seem to work

[Intrepidd]

Hi guys,

I'm starting to hack around with this gem and I'm having an issue with streaming the output of a command.

I'd have thought the block passed to the exec command would be called each time some output is available.

Here's the command I'm using :

container.exec(['/bin/bash', '-c', 'ls && sleep 2 && ls && sleep 2 && ls'], chunk_size: 1) { |stream, chunk| puts chunk.size; $stdout.flush  }

The block is effectively called 3 times, outputting the following :

85
85
85

That's great, however it seems that all blocks are executed when the command stops, and not every second for 3 second as I would have liked :

85
* 1 second sleep*
85
* 1 second sleep*
85

Is this normal behavior ? Is there a gotcha I missed ?

Thanks

After some digging this made the trick :

Docker.options = {:chunk_size => 1}

Seems like chunk_size only works with attach, this will do for now. Sorry for the noise.
