== Ansible module ping host ==
 * ping/test connectivity, create inventory file, and run module ping. {{{
vi inventory.file
[mygrp]
myserver

ansible mygrp -i inventory.file -m ping
}}}
 * Ansible module setup return facts about a host {{{
ansible myserver -i inventory.file -m setup

#Note: add "--tree /tmp/facts" to get facts from multiple servers in groupe, indexed by host
cat /tmp/facts/* | jq '.ansible_facts | .ansible_fqdn + ", " + .ansible_distribution + ", python:"+.ansible_python_version +", IP:" + ( .ansible_all_ipv4_addresses   | join(",")  ) '

#or

== Ansible error's ==
 * 2020-09 [WARNING]: Unable to parse <file> as an inventory source
   * Debug with  {{{
ansible --list-hosts all -i <file> -vvv
}}}
     * error seen "Skipping due to inventory source not existing or not being readable by the current user"  
     * Apparently ansible tries to parse inventory files with different plugins, ini, yaml, etc.

 * 2021-10 "sudo: sorry, you must have a tty to run sudo"
   * Was caused by /etc/ssh/sshd.conf setting {{{ Defaults    requiretty }}}
   * Fix by adding {{{ Defaults:User1,UserX    !requiretty }}}
