1st time using API with Ansible

Hi everyone
I am trying to use Ansible for the first time with an API. Normally I have learned to manage a specific device with ansible where you are connecting to the device.

I have been following this guide(s) to help provide some automation for oVirt virtualization.
https://www.redhat.com/sysadmin//deployment-ansible-design

https://www.redhat.com/sysadmin/deployment-ansible-automation

https://www.redhat.com/sysadmin/deployment-ansible-playbooks

I have copied what the author did except that I customized it for my environment.
When I try to run the playbook I am getting errors. My first question is what should the host parameter be listed as? Shouldn’t it be the oVirt manager? I see the article author chose to use localhost and I’m not sure why. (perhaps this was a generic placeholder?)

Please see the playbook and resulting run below.

  • name: Create Many VMs
    hosts: localhost
    connection: local
    gather_facts: false
    tasks:

Check if all config files exist

  • name: Check if passwords.yml exists
    stat:
    path: vars/passwords.yml
    register: passwordsfile
  • name: Check if file vms.csv exists
    stat:
    path: vars/vms.csv
    register: vmsfile
  • name: Check if file vmtemplates.csv exists
    stat:
    path: vars/vmtemplates.csv
    register: vmtemplatesfile
  • name: Check if file vmflavours.csv exists
    stat:
    path: vars/vmflavours.csv
    register: vmflavoursfile
  • name: Check if file permissions.csv exists
    stat:
    path: vars/permissions.csv
    register: permissionsfile

Check if there is a missing config file terminates the play

  • name: Terminate the play is any variable file is missing
    fail: msg=“Variable file is missing”
    when: passwordsfile.stat.exists is undefined or vmsfile.stat.exists is undefined or vmtemplatesfile.stat.exists is undefined or vmflavoursfile.stat.exists is undefined or permissionsfile.stat.exists is undefined

Parse Config files

  • name: Parse vms.csv file
    read_csv:
    path: vars/vms.csv
    key: name
    register: vms

All the variables are null, then terminate the play.

  • name: Test variables used to deploy multiple VMs
    fail: msg=“Please enter either site or system”
    when: site is undefined and system is undefined

Iterate Over the first and second plays based upon the non-null variables

  • name: Deploy VMs for certain site
    shell:
    cmd: ansible-playbook -e “vmchoice={{ item.value.name }}” --vault-password-file --vault-password-file /path/to/my/vault-password-file

This seems to supply --vault-password-file twice
