[Charlotte-pm] Is there an Ansible solution to this deployment process?

[Yanick Champoux]

## Step 5 of ?: install_service.yml

Ansible by default uses the Jinja2 templating system
(pretty similar to Mustache and Handlebars). In your instructions
you have SITENAME that is a per-host variable, so I'll go back to my
inventory file and augment the host configs with it:

```
all:
  hosts:
    'william.charlotte.us':
      ansible_ssh_host: 192.168.0.103
      sitename: william
   children:
    onboarding:
      hosts:
        'yanick.ottawa.ca':
          sitename: yanick
          ansible_ssh_host: 192.168.0.101
          ansible_ssh_user: yanick
```

I'll assume that `cv.service` is a template (that I'll rename
`cv.service.jinja2`) that might have some tweaks for the
different installs.

So let's do this:

```
# in roles/onboard/tasks/install_service.yml

- name: install service script
  # become means "become the super-user"
  become: yes
  template:
    src: ../files/cv.service.jinja2
    dest: /etc/systemd/system/cv.service
    mode: '644'
   

- name: ensure the service is running
  service:
    name: cv
    enabled: yes
    state: started

```
