Docker-in-Docker driver for Docker Machine

Usage

To build and install, make sure you have a Go 1.6 environment and Docker Machine greater than or equal to 0.5.1. Currently, a godep restore is also needed if the deps do not resolve correctly for you.

Then, just run:

$ make && make install

You need to also ensure that you have built and run the image which gets used to spawn the dind containers:

$ cd image && make && cd -

(Ideally this should be pulled automatically, but this hasn't been added to the driver yet; I would be happy to accept such a change as a patch).

After that, configure your Docker client to talk to a daemon instance (e.g. eval $(docker-machine env)) and run the create:

$ docker-machine create -d dind my-first-dind

Creation is pretty speedy because waiting for the machines to boot is usually the most time-consuming part of the create process, but has definitely highlighted some existing issues with the provisioning and ideally could be faster.

Some features, such as Swarm support, will not work properly unless you are creating with --dind-host set to unix:///var/run/docker.sock (the default on Linux). This is because if --dind-host is set to use the socket, the ip command will return the container's IP on the docker0, and consequently these operations will work similarly to how operating on a public IPv4 address does in the standard Machine cloud provider model. If --dind-host is a remote host (e.g. boot2docker), the Docker URL provided for connection will be based on an arbitrary high port NATed from the container to the host's IP address.
