1. clone the Docker/Docker repository on an ARM device `git clone git@github.com:docker/docker.git`
2. change into the checked out repository with `cd docker`
3. execute `make binary` to create a Docker Engine binary for ARM
## Kernel modules
A few libnetwork integration tests require that the kernel be
configured with "dummy" network interface and has the module
loaded. However, the dummy module may be not loaded automatically.
To load the kernel module permanently, run these commands as `root`.
modprobe dummy
echo "dummy" >> /etc/modules
On some systems you also have to sync your kernel modules.
