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.

Purpose:

• Demonstrate stopping an installed service workload

Example of the file we are writing

example.yml

- hosts: localhost
  gather_facts: false
  vars:
    stop_services:
      - fah.service
  tasks:
    - service_facts:

    - name: stop and disable a service
      service:
        name: "{{ item }}"
        state: stopped
        enabled: false
      when: "item in service_names"
      loop: "{{ stop_services }}"
      vars:
        service_names: "{{ services|dict2items|map(attribute='value.name')|list }}"
    - name: remove apt package
      apt:
        pkg: fah
        state: absent

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