Setting up a new Pi from scratch

  1. Download the latest Raspbian Stretch Lite image, and unzip the downloaded file.

  1. Connect the SD card for the Pi to your computer. Unmount the drive if it is mounted automatically, and determine the device path of your SD card using lsblk or a similar tool that shows device names.

    Use the device's name without any partition numbers, so for instance /dev/sdc instead of /dev/sdc2.

    $ export SD_CARD_DEVICE=/dev/??? # Fill in your own device!

  2. Write the downloaded image to your SD card.

    Warning! This step will erase all data on the device that you've chosen. Be very sure that you're using the correct device, and that you don't care about any data left on the target device.

    $ sudo dd if=*-raspbian-stretch-lite.img of=$SD_CARD_DEVICE bs=4M status=progress; sync

  3. Remove the SD card and boot the Pi. You'll need to connect the Pi with an Ethernet cable to run the playbook for the first time, as there won't be any network connections present.

    Log in using the default credentials (pi, raspberry) and execute the following commands:

    $ sudo systemctl enable --now ssh
$ ip addr

    You should now be able to access the Pi over SSH. Adjust the hosts file for the playbook to contain the correct IP.

  4. Open the ansible directory, and retrieve a Github token. This is needed to retrieve the SSH keys.

    $ cd ansible
$ ./scripts/authorize-github.sh
Please enter your Github username:
maartenberg
Please enter an one-time password, if required, else just press enter.

Token saved!

    You can now build the file with authorized keys:

    $ ./scripts/get-authorized-keys.sh

Updating authorized-keys template.
Done!

  5. Execute the playbook using the following command:

    $ cd ansible
$ ./scripts/run-playbook.sh --ask-pass main.yml

    Enter raspberry as the password.

Your Pi is now ready for use! Reboot the Pi using SSH or ansible -i hosts -m reboot all, and your chosen website should open.
