-====== Ansible - CMOS ======
-In our previous step we [[stack - ansible update|updated Ubuntu]]
-Now we are going to create and run an Ansible playbook to check the CMOS battery health on the nodes. Using /proc/driver/rtc instead of lm-sensors and sensors because it doesn't show the CMOS battery health.
-Purpose:
-  * Demonstrate a simple lineinfile checker
-  * Check for any CMOS batteries that need to be replaced
-====== Step 1 - Log in to Ansible Control Node ======
-From NUC 1, log in to the Ansible control node, NUC 2.
-Steps:
-  - Create file /home/ansible/my-project/cmos-check.yml
-    * <file yaml cmos-check.yml>
----
-- hosts: nodes
-  become: true
-  become_user: root
-  tasks:
-    - name: CMOS battery health
-      lineinfile:
-        path: /proc/drive/rtc
-        line: "batt_status	: okay"
-        status: present
-      check_mode: true
-      register: cmos_battery_ok
-    - name Set hardware clock
-      - command: hwclock -w

-  - Test the playbook
-    * ''ansible-playbook -i hosts cmos-check.yml''
