Raspberry Pi 3

This is my repo for testing configurations on my rpi3. So far what this repo will do is use cloud-init on top of Hypriot to setup a Docker swarm with Portainer and Pi-Hole. You'll have a swarm and ad-blocking DNS in less than the time it takes to brew a cup of coffee.

Usage

I would suggest forking this repo so you can make changes to any config files. Or you could use mine, but the key is to remember I have set the address to 192.168.2.2 for the pi in multiple config files and you will have to either go with that or change it. I also use DHCP from the router to set this is a reserved lease.

First you will need to get the amazing Hypriot flash utility:

curl -LO https://github.com/hypriot/flash/releases/download/2.1.1/flash
chmod +x flash
sudo mv flash /usr/local/bin/flash

You can then download and edit the user-data.yml of this repo: wget https://raw.githubusercontent.com/airbornelamb/rpi/master/user-data.yml

You'll particularly want to change the username, ssh authorized keys (from cat ~/.ssh/id_rsa.pub) and timezone.

After that you are ready to flash the SD card

flash \
  --hostname pi.local \
  --userdata ./user-data.yml \
  https://github.com/hypriot/image-builder-rpi/releases/download/v1.9.0/hypriotos-rpi-v1.9.0.img.zip

If all goes well, the pi will boot up and run cloud-init using user-data.yml. It will automatically resize the root partition, create the user, update and install debian packages, clone this repo, initialize a docker swarm, start a portainer stack, and start a pi-hole stack (using pihole-stack.yml) with volumes mounted in the cloned repo at /var/rpi/pihole

You now have two web admin interfaces:

http://192.168.2.2:9000 is running Portainer. You can browse here and create the first admin user.

http://192.168.2.2/admin is running pi-hole. The DNS forwards to cleanbrowsing.org by default and there is no admin password set.
