Should use a 4GB SD card to minimize the size and time
I used raspbian-buster-lite
Flash the Image to an SD card (using etcher or whatever)
Once flashed remount it and open up the root directory.
Add an empty file named ssh. This will allow you to ssh into it using:
pi@XXX.XXX.XXX.XXX
password: raspberry
If you don't have ethernet available then you'll need to setup wpa_supplicant
Inside the same root diretory add a file named "wpa_supplicant.conf"
Add your wifi connection details:
country=us
update_config=1
network={
scan_ssid=1
ssid="MyNetworkSSID"
psk="Pa55w0rd1234"
}
sudo apt update
sudo apt install -y
apt-transport-https
ca-certificates
curl
gnupg2
software-properties-common
curl -fsSL https://download.docker.com/linux/$(. /etc/os-release; echo "$ID")/gpg | sudo apt-key add -
echo "deb [arch=armhf] https://download.docker.com/linux/$(. /etc/os-release; echo "$ID")
$(lsb_release -cs) stable" |
sudo tee /etc/apt/sources.list.d/docker.list
The aufs package, part of the "recommended" packages, won't install on Buster just yet, because of missing pre-compiled kernel modules.
sudo apt update
sudo apt install -y --no-install-recommends
docker-ce
cgroupfs-mount
sudo usermod -aG docker pi
reboot (or use sudo to run docker for right now)
sudo apt install netcat
sudo apt install -y jq
mkdir /home/pi/.ancilla
To use the wifi docker image we need to disable the main wpa_supplicant.
sudo systemctl mask wpa_supplicant.service
sudo pkill wpa_supplicant
sudo mv /sbin/wpa_supplicant /sbin/no_wpa_supplicant
From Local Device: Copy ancilla.service, ancilla.sh, wificfg.json, config.json to image
scp -r /path/to/ancilla/ancilla.service pi@192.XXX.XXX.XXX:/home/pi/ancilla.service scp -r /path/to/ancilla/ancilla.sh pi@192.XXX.XXX.XXX:/home/pi/ancilla.sh scp -r /path/to/ancilla/.env pi@192.XXX.XXX.XXX:/home/pi/.env
scp -r /path/to/ancilla/ancilla/wificfg.json pi@192.XXX.XXX.XXX:/home/pi/.ancilla/wificfg.json scp -r /path/to/ancilla/ancilla/config.json pi@192.XXX.XXX.XXX:/home/pi/.ancilla/config.json
On Remote:
sudo mv ancilla.service /lib/systemd/system/ancilla.service sudo systemctl enable ancilla sudo systemctl daemon-reload
Make sure you're connected to network first time and then run:
sudo systemctl start ancilla
This will pull down the wifi and ancilla images
validate that both images are running
docker ps
also check to see if ancilla-setup-xxxxx wifi network appeared
If you added wpa_supplicant file then you'll want to remove your creds before creating the image: Edit /etc/wpa_supplicant/wpa_supplicant.conf and delete the network information.
Then we can stop and remove the containers (not the images)
docker stop wifi docker rm wifi docker stop ancilla docker rm ancilla
sudo systemctl stop ancilla (otherwise when we edit the wificfg.json file it will get regenerated)
Update the ssid field in wificfg.json file to be an empty string.
This will allow the ancilla script to generate a new one.
sudo vi /boot/cmdline.txt

sudo chmod +x /etc/init.d/resize2fs_once sudo systemctl enable resize2fs_once
turn off the pi take the sd card and mount it on your computer On Mac can use disk utility Select the external disk you just mounted (select the parent and not the boot partition) Right click on it and select "Image from 'device name'" Change format to cd/dvr and create the image
When finished you can rename it .iso instead of .cdr Then you can use etcher to flash it to another memory card
