-====== Discover NUCs and add to inventory ======
-Now that you have your [[Stack of NUCs]] all built, updated, and connected to the wireless network, it is time to set them all up in the Ansible inventory so we can start doing things with them.
-Purpose:
-  * Discover local hosts that the Ansible control node can access
-  * Add these hosts to our inventory
-Steps:
-  - power on all the nodes
-  - run the discovery script from the Ansible control node ([[NUC 2]])
-    * <file bash>
-IPs=$(sudo arp-scan --localnet --numeric --quiet --ignoredups | grep -E '([a-f0-9]{2}:){5}[a-f0-9]{2}' | awk '{print $1}')
-for i in $(IPs"); do
-  # set up SSH managment keys
-  ssh-keygen -R $i && ssh-keyscan -H $i >> ~/.ssh/known_hosts
-  # identify hosts ansible can access
-  ssh $i "uname -I" && echo $i
-done
