I have setup too many beaglebone and raspberries for IoT gateways. I did have a nice check list of each step to take, then someone showed me ansible.

So working towards all of that automation.

I don't install ansible on my machine, but instead run it inside a Docker container.

Things go a lot smoother if you have put public keys in place.

ssh-copy-id -i ~/.ssh/id_rsa $NODES

1. Build: docker build -t local/ansible-playbook:latest .
2. Run with: ansible_helper

Currently, if you want to setup a Raspberry Pi without keyboard or monitor do the following:

• Copy image to SD Card
• Mount it
• Add empty file to the SD Card named ssh
• Add a file named wpa_supplicant.conf with the following:

country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
scan_ssid=1
ssid="$your_wifi_ssid"
psk="$your_wifi_password"
}

• There appears to be support for a firstuse.sh script, but it also appears to be undocumented.
• Eject SD Card from computer
• Insert to Raspberry PI
• Boot device
• Wait a minute or three
• ssh [email protected].; default password
• sudo raspi-config
• Change hostname and passwords and resize the filesystem
• Reboot

1. Press ⌘⇧X (or ⌃⇧X if not Mac) to access the advanced options.
2. Check ssh box and WiFi setup and change hostname
3. Write image
