Hi everyone
I am trying to use Ansible for the first time with an API. Normally, I have learned to manage LInux servers with ansible where you are connecting to the device(s) using SSH and an inventory file.
I have been following this guide(s) to help provide some automation for oVirt virtualization.
https://www.redhat.com/sysadmin//deployment-ansible-designhttps://www.redhat.com/sysadmin/deployment-ansible-automationhttps://www.redhat.com/sysadmin/deployment-ansible-playbooksI have generally 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. Can someone explain? I'm still trying to get my head wrapped around it and understand what's happening.
My file structre is as follows:
[student@workstation ansible]$ tree
├── many-vms.yml
└── vars
├── passwords.yml
├── permissions.csv
├── pwfile.txt
├── vmflavours.csv
├── vms.csv
└── vmtemplates.csv
Here is my playbook:
---
