steps.md

Install HypriotOS

Insert each sd card on a laptop, mine laptop OS is Mac OSX. Download the HypriotOS. Install flash before starting.

$ wget -c  https://downloads.hypriot.com/hypriotos-rpi-v0.8.0.img.zip 
$ flash -n rpi[1-n] hypriotos-rpi-v0.8.0.img.zip

Turn on power of the cluster.

Install Ansible

On Mac do

brew install ansible

We use ansible to verify every machine is on. Firstly define an inventory file like below


[masters]
192.168.1.101

[etcd]
192.168.1.101

[nodes]
192.168.1.102
192.168.1.103
192.168.1.104
192.168.1.105
192.168.1.106
192.168.1.107

$ export ANSIBLE_HOST_KEY_CHECKING=False
$ ansible -k  -u pirate -i inventory all -m shell -a "hostname"

The command line will prompt SSH password:, enter the default password hypriot, we will see all hosts' name.

SSH password: hypriot

192.168.1.105 | SUCCESS | rc=0 >>
rpi5

192.168.1.106 | SUCCESS | rc=0 >>
rpi6

192.168.1.102 | SUCCESS | rc=0 >>
rpi2

192.168.1.103 | SUCCESS | rc=0 >>
rpi3

192.168.1.104 | SUCCESS | rc=0 >>
rpi4

192.168.1.107 | SUCCESS | rc=0 >>
rpi7

192.168.1.101 | SUCCESS | rc=0 >>
rpi1

Here very likely you will run into a MODULE FAILURE, add '-vvvv' on the previous ansible script. You will see it's because HypriotOS by default doesn't install python. You need to write a shell script install it on every machine.

Enable keyless login

$ ansible-playbook -k -u pirate -i inventory cluster.yml  --tags enable-keyless

Build Golang

env GOROOT_BOOTSTRAP=$HOME/go-linux-arm-bootstrap GOOS=linux GOARCH=arm GOARM=7 ./make.bash --no-banner

Compile kubernetes, etcd and fannel

etcd tar ball

./build-etcd v2.3.6

sudo journalctl | grep -i etcd
