Get output of #attach in sequential order about docker-api HOT 6 CLOSED

I think it is possible to change docker-api to returns a concatenated string in the order returned in the response from docker. But the order in which docker will return data is probably not that deterministic as the there is no concept of "order" between file descriptors.

@wader Yes, now that I think about it I can see why I never should have even cared about stdout and stderr coming in at the "right" order.

But if I do something like container.attach[0].join, that'll get me stdout in the order it was outputted to, right?

(Closing this issue as it's not an issue at all.)

Yeah that should work fine and be in correct order

@wader Thanks!

Since attach takes a block, the block will be yielded which stream it came from and the data from that stream.

data = ""
container.attach do |stream, msg|
  data << msg
end
puts data

This might be in the order you want? As @wader said though, who knows how Docker deals with it.

@tlunter I think I'll stick with getting stdout and stderr separately, that seems like the "proper" way to do it.

Thanks for the help.
