Ansible: Raspberry Pi Zero Provisioner

An Ansible provisioner for Raspberry Pi Zero W

1. Install Ansible

More Details: http://docs.ansible.com/ansible/latest/intro_installation.html#latest-releases-via-pip

1. sudo easy_install pip
2. sudo pip install ansible

2. Setup User Variables

In the vars/user.yml file you can copy and overwrite any variables listed in the vars/main.yml file. Most importantly, double check that the ssh key path and wifi connection details are correct for your setup. See all recommended variables below:

Variable	Default	Description
user	Content from cell 1	Content from cell 2
ssh_directory	/home/pi/.ssh	The directory the install will create to store your authorized_key
nvm_version	0.33.2	Version of node version manager
node_version	node	Node version. NVM aliases like node or stable are also accepted.
ssh_key_path	~/.ssh/id_rsa.pub	The path on your LOCAL machine where your public ssh key can be found. This will be copied to the pi as an authorized_key
dont_show_wifi_connections	True	Determines if wifi details will be logged to console during setup
wifi	{ ssid: 'testaddress', password: 'testpass' }	An array of ssid and password combinations. Find available ssid using `sudo iwlist wlan0 scan
apt_packages	git & vim	apt-get packages you would like installed. Each package should be added on its own line (see example below).

Overwrite Example

In var/user.yml

node_version: 8.2.0

wifi:
  - { ssid: 'myactualssid', password: 'mywifipassword' }
  - { ssid: 'anotherwifissid', password: 'anotherpassword' }
  
apt_packages
  - git
  - vim

3. Run the Setup

cd into repository and run make to run the initial install. You will be prompted to enter your ssh password. By default, this should be raspberry. If you already have an ssh key setup or are running a subsequent time, use make setup. Other make commands and manual ansible commands if that's how you roll:

Ansible Command	Make Command	Use
ansible-playbook setup.yml --ask-pass	make or make all	Runs the full playbook. Should be used on the initial setup. For subsequent runs, use make setup so that you aren't prompted for a password.
ansible-playbook setup.yml	make setup	Runs the full install, but does not require a manual ssh password. Will error if run initially.
ansible-playbook setup.yml --tags=wifi	make wifi	Runs only the wifi section of the playbook. Great for quickly adding one or more wifi connections.
