# ARM support
|
|
|
|
The ARM support should be considered experimental. It will be extended step by step in the coming weeks.
|
|
|
|
Building a Docker Development Image works in the same fashion as for Intel platform (x86-64).
|
|
Currently we have initial support for 32bit ARMv7 devices.
|
|
|
|
To work with the Docker Development Image you have to clone the Docker/Docker repo on a supported device.
|
|
It needs to have a Docker Engine installed to build the Docker Development Image.
|
|
|
|
From the root of the Docker/Docker repo one can use make to execute the following make targets:
|
|
- make validate
|
|
- make binary
|
|
- make build
|
|
- make deb
|
|
- make bundles
|
|
- make default
|
|
- make shell
|
|
- make test-unit
|
|
- make test-integration
|
|
- make
|
|
|
|
The Makefile does include logic to determine on which OS and architecture the Docker Development Image is built.
|
|
Based on OS and architecture it chooses the correct Dockerfile.
|
|
For the ARM 32bit architecture it uses `Dockerfile.armhf`.
|
|
|
|
So for example in order to build a Docker binary one has to:
|
|
1. clone the Docker/Docker repository on an ARM device `git clone https://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.
|
|
|
|
oc-sync-kernel-modules
|
|
depmod
