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

4. Add script to ~

nano shutdown-script.sh && chmod +x $_

5. Copy paste the script it from here

6. Reboot
   sudo reboot
