Vars and Playbooks
Let's take a look at the group_vars, host_vars, and playbooks folders in the repository.
We'll cover the following
group_vars
The group_vars
folder contains the data models applied to groups of
devices found in the hosts
file. This folder contains YAML files
created to contain data models. group_vars
folder matching the
sample hosts
file is as follows:
group_vars
|
---- ENTERPRISE.yml|
---- CAMPUS.yml
---- CAMPUS-CORE.yml
---- CAMPUS-DISTRIBUTION.yml
---- CAMPUS-ACCESS.yml
---- CAMPUS-ACCESS-3850.yml
---- CAMPUS-ACCESS-3750.yml
---- DATA-CENTER.yml
---- DATA-CENTER-7K.yml
---- DATA-CENTER-5K.yml
---- WAN.yml
---- WAN-ISR.yml
---- WAN-ACCESS.yml
---- DMZ.yml
host_vars
The hosts_vars
, similar to the group_vars
folder, contains the
data models that apply to each device or host in the hosts
file. This folder again contains YAML files. However a file using the device’s hostname is also created per device.
host_vars
folder matching the sample hosts
file is as
follows:
hosts_vars
|
---- CORE.yml
---- DIST01.yml
---- DIST02.yml
---- ACCESS01.yml
---- ACCESS02.yml
---- ACCESS03.yml
---- DC01_7K.yml
---- DC02_7K.yml
---- DC01_5K.yml
---- DC02_5K.yml
---- WANISR01.yml
---- WANACCESS01.yml
---- DMZ01.yml
---- DMZ02.yml
playbooks
The playbooks
folder is required in the Ansible framework. This is
where YAML files that make up Ansible playbooks are stored. It is a good
idea to have some structure, either by platform or function, as well as
another level of folders for network reconnaissance playbooks, tactical
playbooks, and network management playbooks. Think of these as
executables. We can use ansible-playbook
commands to run these playbooks.
