Table 1. General Docker Commands
Simple Ad-Hoc Command	`ansible all -m ping`
Specify specfic host, note `,`	`ansible all 192.9.200.1, -m ping`
Specify inventory file	`ansible all -i inventory -m ping`
Pass arguments to module	`ansible web -m yum -a "name=httpd state=present`

Common options

-m module name, e.g. yum
-i inventory source
- -i hosts read inventory from file hosts
- -i inventory/ec2.py execute dynamic inventory script

Table 2. Ansible Playbook Comamands
Simple A`ansible-playbook` Command	`ansible-playbook main.yml`
Simple A`ansible-playbook` Command	`ansible-playbook main.yml`
`ansible all 192.9.200.1, -m ping`	Specify inventory file
`ansible all -i inventory -m ping`	Pass arguments to module

`ansible.cfg` files

Precedence

Sample ansible.cfg with callbacks enabled

[defaults]
inventory               = inventory
stdout_callback         = default
bin_ansible_callbacks   = True
callback_whitelist      = yaml, timer, profile_tasks

[ssh_connection]
ssh_args                = -F ./ssh.cfg (1)

All ssh configuration encapsulated in ssh.cfg file

In-Memory Inventory Examples

A common pattern in cloud, VM, or Container creation is to create the objects (e.g. using say ec2 module) then

Get instance facts

Call add-host with instance facts register

name: Fetch Instance Info          (1)
  os_server_facts:
   cloud: ospcloud
   region_name: RegionOne
  register: result

- name: Add host                   (2)
  add_host:
    name: "{{ item.public_v4 }}"
    group: "{{ item.metadata.group }}"
  loop: "{{ result.ansible_facts.openstack_servers }}"
