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

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

Create the file /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
    - name: Reboot
      reboot:

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

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

ansible-playbook removefah.yml

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

Cyber security students may want to deploy hashtopolis in the Lab. This deploys a distributed hashcat cluster for brute forcing password hashes.
