attach, read tty and send out CLI commands

[andrius]

My script should attach to the running container, grab tty input and based on content, send some data. (there is some telnet command that could produce various data sets from test device)

How I can do something like in pseudocode below?

container = Docker::Container.get('container-id-or-name')
a = container.attach
while true
  line = a.gets.to_s.chomp.strip
  break if line.empty?
  if line == 'value'
    a.puts "some-data"
  elsif line == '...'
    # ...
  end 
end

Why not use websocket to attach a docker container. I'm using socket to attach, and it works fine.
