As part of OPNFV integration we need to validate running ONAP on ARM processor cores. My only experience with ARM is during iOS development or on Broadcom chips. We will run on the Broadcom chips to start. Note that this is pure experimentation - in that the granularity of the v3 boards is only 1Gb - which will not run most of our pods properly.

Bare Metal Setup
Flash Raspian to all the SD cards
Enable ssh, wireless, rename host
sudo nano /etc/wpa_supplicant//wpa_supplicant.conf
Docker Setup
curl -sSL https://get.docker.com | sh
sudo usermod -aG docker pi
Note: Docker 17.11.0-ce requires memory control groups - either downgrade to 17.09.0-ce or adjust /boot/cmdline.txt
