raspberry ready

The script I use when my raspberry pi turns on.

Setup (headless)

  1. Install Raspberry Pi Imager from here and flash the latest lite version with the following settings:

    • hostname: raspberrypi
    • username & password: pi / pass
    • no wlan
    • locale: Europe/Bucharest, keyboard: us
    • enable ssh with password authentication

  2. SSH into your device ssh pi@raspberrypi

  3. Update software / firmware

    sudo apt update && \
sudo apt full-upgrade -y && \
sudo apt autoremove && \
sudo apt clean

  4. Reboot sudo reboot

Overclock

  1. Open the config file sudo nano /boot/firmware/config.txt and add the following: 
    over_voltage=6
arm_freq=2000

Instalation

  1. Install docker curl -sSL https://get.docker.com | sh
  2. Add permission to pi user to run docker commands sudo usermod -aG docker pi
  3. Test docker installation docker run hello-world
  4. Install docker-compose (check for latest version here) 
    sudo curl -L https://github.com/docker/compose/releases/download/v2.26.1/docker-compose-`uname -s`-`uname -m` > docker-compose && \
sudo mv docker-compose /usr/bin/ && \
sudo chown root: /usr/bin/docker-compose && \
sudo chmod +x /usr/bin/docker-compose

Run on startup

  1. Symlink /etc/rc.local to ~
    ln -s /etc/rc.local startup

  2. Open startup
    sudo nano startup

  3. Before exit add scripts (important: the --privileged flag is needed in order to access the GPIO from the container)

# Run ready scripts
sudo /home/pi/./shutdown-script.sh &
docker run --privileged --rm --name ready -d -v /var/run/shutdown_signal:/shutdown_signal highstrike/raspberry-ready:v1.0.8
  1. Add script to ~
nano shutdown-script.sh && chmod +x $_

  1. Copy paste the script it from here

  2. Reboot
    sudo reboot
