Let us enter the proxy VM and start exploring different networking options. Vagrant ssh proxy cd /vagrant/articles/dns The dns directory contains all the code we’ll need throughout this article.

For those looking at this thread who are running Docker 1.8 or newer, the syntax from Andy's and Muneeb's comments no longer work (the theory is the same), since boot2docker has been deprecated and replaced with docker-machine and the docker VM name changed [1]. Forwarding a single port Mac -> VM -> container If you just want to forward port 80 inside a container using the default network options to port 8080 on your Mac, do this: a) Expose port 80 either with an EXPOSE 80 in the Dockerfile or --expose=80 in docker run. Add /udp for UDP ports. B) Map the ports from the container to the VM with -p 8080:80 in docker run. Add /udp for UDP ports. C) Tell the docker VM (now called 'default') to add a NAT mapping between port 8080 on the VM and port 8080 on your Mac: VBoxManage controlvm default natpf1 'port8080,tcp,,8080,,8080'. The first port is on your Mac; the second port is on the VM.
To delete the rule use VBoxManage controlvm default natpf1 delete port8080. Note: VBoxManage controlvm changes a running VM, modifyvm changes a VM that is stopped.
Getting the IP address of your docker VM New syntax is docker-machine ip default (default is the name of docker VM).
