You can use vagrant-proxy docker support for docker hosts on ubuntu, RHEL(6,7), CoreOS, boot2docker and so on.

It is easy to use. Install vagrant-proxyconf, then add your proxy configuration to Vagrantfile. If you already use vagrant-proxyconf, you don't need extra configuration for vagrant-proxy docker support.
