How to use docker-py (official docker client) to start a bash shell?
Question: I'm trying to use docker-py to run a docker container and drop me into a bash
shell in that container. I get as far as running the container (I can see it
with `docker ps`, and I can attach to it just fine with the native docker
client), but when I use `attach()` from the official Python library, it just
gives me an empty string in response. How do I attach to my bash shell?

    
    
    >>> import docker
    >>> c = docker.Client()
    >>> container = c.create_container(image='d11wtq/python:2.7.7', command='/bin/bash', stdin_open=True, tty=True, name='docker-test')
    >>> container
    {u'Id': u'dd87e4ec75496d8369e0e526f343492f7903a0a45042d312b37859a81e575303', u'Warnings': None}
    >>> c.start(container)
    >>> c.attach(container)
    ''
    


Answer: I ended up releasing a library for this: <https://github.com/d11wtq/dockerpty>

    
    
    import docker
    import dockerpty
    
    client = docker.Client()
    container = client.create_container(
        image='busybox:latest',
        stdin_open=True,
        tty=True,
        command='/bin/sh',
    )
    client.start(container)
    
    dockerpty.PseudoTerminal(client, container).start()
