Raspberry Pi OS Setup¶

These steps provide the initial configuration for a Raspberry Pi that will be managed by Ansible.

Raspberry Pi OS setup¶

Flash Raspberry Pi OS Lite (64-bit) to an SSD connected over USB using Raspberry Pi Imager.
Select the cog icon to open the advanced options and configure the following settings:
Set the hostname to the hostname of the host to be deployed.
Enable SSH and allow public key authentication only. Enter the public key that will be used to connect to the host.
Set a username and password.
Set the locale settings as appropriate.
Disable telemetry.
Connect the SSD to the Raspberry Pi over USB and boot it.
Find the Raspberry Pi's IP address by scanning the local network:
```
sudo nmap -sn 192.168.0.1/24
```
SSH to the Raspberry Pi using the configured username and hostname or IP address:
```
ssh <username>@<hostname>
```
Note

If hostname resolution does not work, use the Raspberry Pi's IP address or resolve the hostname. You may need to restart the mDNS service on macOS:
```
sudo killall -HUP mDNSResponder
```

Run the following commands on the Raspberry Pi to configure its static network address and update the system:

# Network configuration
INTERFACE="eth0"
IP_ADDRESS="192.168.0.2/24"
GATEWAY="192.168.0.1"
DNS_SERVERS="45.90.28.138,45.90.30.138"

# Set the static IP address
sudo nmcli connection modify "${INTERFACE}" \
  ipv4.method manual \
  ipv4.addresses "${IP_ADDRESS}" \
  ipv4.gateway "${GATEWAY}" \
  ipv4.dns "${DNS_SERVERS}" \
  connection.autoconnect yes

# Apply the network configuration
sudo nmcli connection up "${INTERFACE}"

# Update the system
sudo apt-get update
sudo apt-get upgrade -y
sudo reboot
