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 onto an sdcard or ssd

2. Create an empty SSH file in the boot partition

3. Create a file called wpa_supplicant.conf in the boot partition with the contents

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=RO

network={
  ssid="Unimatrix"
  psk="<SECRET_PASS_HERE>"
}

4. SSH into your device (default password is raspberry)
   ssh pi@raspberrypi

5. Update software / firmware

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

6. Change default password and timezone
   sudo raspi-config

7. Reboot
   sudo reboot

Overclock

1. Open the config file
   sudo nano /boot/config.txt

2. Uncomment and add the following lines

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. Reboot
   sudo reboot

4. Test docker installation
   docker run hello-world

5. Install dependencies for docker-compose

sudo apt install -y libffi-dev libssl-dev && \
sudo apt install -y python3 python3-pip

6. Install docker-compose
   sudo pip3 install 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 ~

touch shutdown-script.sh && \
chmod +x shutdown-script.sh && \
nano shutdown-script.sh

5. Copy paste the script it from here

6. Reboot
   sudo reboot
