From NUC 1, log in to the Ansible control node, NUC 2.

In our previous step we set up FAH on our Stack of NUCs.

Now we are going to disable the service and uninstall it.

Purpose:

• Demonstrate stopping and removing an installed service workload

Steps:

1. ansible-playbook removefah.yml (/home/ansible/my-project/fah/removefah.yml)

   • removefah.yml

     ---
     - hosts: all
       become: true
       become_user: root
       tasks:
         - name: Stop and disable FAHClient.service
           ansible.builtin.service:
             name: FAHClient.service
             state: stopped
             enabled: false
         - name: Remove fahclient package
           apt:
             name: fahclient
             state: absent
             clean: true
             purge: true

2. ansible-playbook reboot.yml (/home/ansible/my-project/fah/reboot.yml)

   • ---
     - hosts: all
       become: true
       become_user: root
       tasks:
         - name: Reboot
           reboot:

Now that we have removed the CPU-hungry FAH service, we go next to installing Kubernetes
