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

pi@pi0:~ $ docker run hello-world Status: Downloaded newer image for hello-world:latest docker: Error response from daemon: cgroups: memory cgroup not supported on this system: unknown. ERRO[0007] error waiting for container: context canceled pi@pi0:~ $ docker version Client: Version: 17.11.0-ce OS/Arch: linux/arm pi@pi0:~ $ sudo apt install docker-ce=17.09.0~ce-0~raspbian pi@pi0:~ $ docker run hello-world Hello from Docker! pi@pi0:~ $ sudo nano /boot/cmdline.txt pi@pi0:~ $ cat /boot/cmdline.txt # add to the end of first line: cgroup_enable=memory cgroup_memory=1 # reboot
