# Quick Deployment

[![GitHub logo](/assets/github_logo.png "peach-config GitHub repository")](https://github.com/peachcloud/peach-config)

The instructions, configuration files and scripts referred to in this section can all be found in the [peach-config repo](https://github.com/peachcloud/peach-config).

## Prerequisite Steps

Download the latest Debian Buster preview image for RPi3 and flash it to an SD card.

Note: Be sure to use the correct device location in the `dd` command, otherwise you risk wiping another connected USB device. `sudo dmesg | tail` can be run after plugging in the SD card to determine the correct device location:

```bash
wget https://raspi.debian.net/verified/20200831_raspi_3.img.xz
xzcat 20200831_raspi_3.img.xz | sudo dd of=/dev/mmcblk0 bs=64k oflag=dsync status=progress
```

On Mac OS, use the following command to flash the SD card:

`xzcat 20200831_raspi_3.img.xz | sudo dd of=/dev/sdcarddisc`

Alternatively, use [Etcher](https://www.balena.io/etcher/).

Note: if the above image link stops working, you can find the complete list of Raspberry Pi Debian images [here](https://raspi.debian.net/tested-images/).

## Setup

Quick setup commands to connect to a local WiFi network over the `wlan0` interface (assuming `eth0` connection is not possible):

```bash
# username
root
# password (by default raspberry debian requires no password, so we set the password for root here)
passwd
# set interface up (run command twice if you receive 'link is not ready' error on first try)
ip link set wlan0 up
# append ssid and password for wifi access point
wpa_passphrase <SSID> <PASS> > /etc/wpa_supplicant/wpa_supplicant.conf
# open wpa_supplicant.conf
nano /etc/wpa_supplicant/wpa_supplicant.conf
```

[ Add the following two lines to top of file ]

```plaintext
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wpactrl-user
update_config=1
```

[ Save and exit ]

```bash
# open network interfaces config
nano /etc/network/interfaces
```

[ Add the following lines to the file ]

```plaintext
auto lo
iface lo inet loopback

allow-hotplug wlan0
auto wlan0
iface wlan0 inet dhcp
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
```

[ Save and exit ]

`reboot now`

[ Pi should now be connected to the WiFi network ]

## Scripts

The `setup_dev_env.py` script can be executed once your Pi is internet-connected and `git` and `python` have been installed. It takes a `<USER>` argument to create a new system user. You will be prompted to enter a password for your newly created user. The script will install system requirements and copy configuration files relating to networking, I2C and RTC.
The i2c and rtc flags are optional and can be removed for installation without the peripheral hardware.

_TODO: Add flags to (de)select Rust install & config. Flags should also be added which allow the installer to choose between development environment and release environment configuration._

```bash
apt update
apt install git python
git clone https://github.com/peachcloud/peach-config.git
cd peach-config
python scripts/setup_dev_env.py --i2c --rtc ds3231 <USER>
```
