Pi: Setup Walkthrough

Script [approx 40m for 4 Pis]

UPDATE: Can follow this instead of etcher: https://ubuntu.com/tutorials/how-to-install-ubuntu-on-your-raspberry-pi#2-prepare-the-sd-card

1. Etcher.io: burn image [approx 2m 30s]
2. Save Empty ssh file on /boot
3. Login: ssh pi@raspberrypi, password raspberry
4. Run Setup script: bash -c "$(wget -O - https://raw.githubusercontent.com/piarmy/piarmy-scripts/master/setup/deviceSetup.sh)" [approx 6m]
5. Update password
6. Name host: piarmy0[n]
7. Copy ssh key to Github when prompted
8. After script completes, run sudo smbpasswd -a pi , entering same password as above when prompted
9. Reboot: sudo reboot
10. Check: docker info

Post Setup config

Clone piarmy-scripts

1. cd /home/pi/projects && git clone git@github.com:piarmy/piarmy-scripts.git && cd piarmy-scripts

Copy keys accross all pis

Run this from piarmy01 (or whatever the manager node will be)

1. cd /home/pi/projects/piarmy-scripts/setup
2. Edit copy keys script: nano piarmyCopyKeys.sh (change password variable)
3. Run copy keys script: . piarmyCopyKeys.sh
4. Run script on remote nodes:

ssh pi@piarmy02 'bash -s' < piarmyCopyKeys.sh && \
  ssh pi@piarmy03 'bash -s' < piarmyCopyKeys.sh && \
  ssh pi@piarmy04 'bash -s' < piarmyCopyKeys.sh

USB mounting (optional)

Follow these steps if you have USB drives in your Pis.

ssh into each pi and format drive to EXT4: sudo mkfs.ext4 /dev/sda1 -L minio

From manager node, run:

cd /home/pi/projects/piarmy-scripts/setup && \
  . automount_usb.sh && \
  ssh pi@piarmy04 'bash -s' < automount_usb.sh && \
  ssh pi@piarmy04 'bash -s' < automount_usb.sh && \
  ssh pi@piarmy04 'bash -s' < automount_usb.sh

Git config

Replace: YOUR_EMAIL and YOUR_NAME with the proper values below and run command:

git config --global user.email "YOUR_EMAIL" && git config --global user.name "YOUR_NAME" && git config -l && \
  ssh pi@piarmy02 "git config --global user.email 'YOUR_EMAIL' && git config --global user.name 'YOUR_NAME' && git config -l" && \
  ssh pi@piarmy03 "git config --global user.email 'YOUR_EMAIL' && git config --global user.name 'YOUR_NAME' && git config -l" && \
  ssh pi@piarmy04 "git config --global user.email 'YOUR_EMAIL' && git config --global user.name 'YOUR_NAME' && git config -l"

Clone other project repos

cd /home/pi/images  && \
  git clone git@github.com:piarmy/piarmy-collector.git && \
  git clone git@github.com:piarmy/piarmy-webserver.git && \
  git clone git@github.com:piarmy/piarmy-lambda.git

Swarm Setup

1. cd /home/pi/projects/piarmy-scripts/swarm
2. Run Swarm init script: . piarmy-swarm-init.sh
3. Check: docker node ls

Should produce something similar:
