-====== Stack of NUCs ======
-The mission in this Lab is to create genuine hands-on experience for technology learners using the learner-friendly NUC PCs.
-Mission:
-  * Auto install Ubuntu servers
-  * Install and use Ansible to manage our servers
-  * Install and run a FAH protein folding cluster
-  * Install a Kubernetes cluster
-Materials:
-  * Wireless router providing DHCP and internet access
-  * NUCs
-    * 4 minimum for the Kubernetes portion; 5 recommended, or more are recommended for testing Kubernetes resiliency
-    * wifi cards to make it easier to run large stacks of NUCs
-    * D34010WYK was used to Lab testing as they are readily available; I used 8GB RAM and 32GB or greater mSATA SSDs
-  * USB sticks
-    * 3 USB sticks, 8GB or more each
-    * Using a pair of sticks for booting and one more for firmware upgrades
-More projects:
-  * Trying running different workloads on your Stack of NUCs
-  * If you are interested in testing Kubernetes, there are some good tutorials on running Kubernetes all on one NUC using LXD to virtualize all the nodes.

-====== Project Overview ======
-Before starting the Lab, you might review [[Preparing NUCs for Labs]]. The will help you prepare all the NUCs for use.
-===== Set Up NUC 1 =====
-[[Stack - NUC 1|NUC 1]] - install Ubuntu desktop on the first build
-  * install Ubuntu and packages on [[Stack - NUC 1|NUC 1]]
-  * create the modified ISO for USB installation of remaining NUCs
-  * create the CIDATA USB stick
-  * create the firmware upgrade USB stick
-  * create SSH management keys
-===== Set Up NUC 2 =====
-[[Stack - NUC 2|NUC 2]] - install Ubuntu on Ansible control node
-  * automatic install of Ubuntu
-  * configure as Ansible control node
-===== Set Up NUC 3 and Remaining NUCs =====
-[[Stack - NUC 3|NUC 3]] - Build remaining NUCs starting with NUC 3
-  * automatic install of Ubuntu
-  * configure as Ansible node
-  * repeat for as many nodes as desired
-===== Discover NUCs and add to Inventory =====
-[[Stack - Discover and Add to Inventory|Discover and Add to Inventory]] - Discover the worker nodes you built and add them to Ansible's inventory.
-===== First Ansible Playbook - Update =====
-[[Stack - Ansible - Update|Ansible - Update]] - update Ubuntu packages on all the NUCs in the stack
-===== Second Ansible Playbook - CMOS Battery Health and Clock Setting =====
-[[Stack - Ansible - CMOS|Ansible - CMOS]] - use Ansible to check the CMOS battery and update the hardware clock on the RTC (real time click) chip
-===== Installing FAH with Ansible =====
-[[FAH Installation]] - install Folding at Home on our [[Stack of NUCs]] and donate CPU time towards a good cause.
-===== Removing FAH with Ansible =====
-[[FAH Removal]] - it's time to remove Folding at Home so we can continue to the next demonstration.
-===== Installing Kubernetes with Ansible =====
-[[Install Kubernetes]] - we will install Kubernetes using Ansible.
-===== Demonstrating a Web App on Kubernetes =====
-[[stack_-_demonstrate_app_on_k8s|Demonstrate App on k8s]] - demonstrate running a web app on the Kubernetes cluster.
-===== Install HA Proxy =====
-[[stack - install haproxy|Install HAProxy]] - demonstrate using HA proxy to load balance across the pods.
-===== Next Step =====
-Let's get started with building our first NUC, [[Stack - NUC 1|NUC 1]]!
