How to solve truncated docker output in Mac OS X using boot2docker

If you are using docker on Mac OS X using boot2docker (http://docs.docker.io/installation/mac/), you may see truncated output from docker run, and also may have noticed that docker attach does not work properly, producing only some output and then exiting. This bug is documented here: https://github.com/boot2docker/boot2docker/issues/150, where I also found the following workaround. Documenting it here in case anyone finds it useful:

Instead of using the default value of DOCKER_HOST provided by boot2docker up, establish the docker connection through an ssh tunnel:

    $ boot2docker ssh -L 14243:127.0.0.1:4243 -N
    docker@localhost's password: <type password>
    [press Ctrl-z to suspend the command]
    $ bg
    $ export DOCKER_HOST=localhost:14243

Now all docker connections will go through the ssh tunnel instead of through VirtualBox port forwarding, and things will work fine.
