Ansible Dynamic Inventory for MySQL

Ansible Dynamic Inventory for MySQL

This is a Dynamic Inventory for Ansible to be used together with MySQL.

It was written because we maintain a lot of servers and static inventory files did not meet our demand, and we like MySQL.

Usage

Simply call the script like the following

ansible-playbook -i mysql.py
# or
ansible -i mysql.py

Limitations also work

ansible-playbook -i mysql.py --limit foo.bar.com
ansible-playbook -i mysql.py --limit groupFoo

Setup

I won't explain the process of installing a database or creating the tables, see tables.sql for the required MySQL structure.

Once setup rename mysql.ini.dist to mysql.ini to suit your needs, if you don't want to use caching just put it on 0.

Groups

In the table group you create the groups you need and their variables,

Hosts

In the table host under host you place the IP/DNS for the system.

Facts

Under hostname you can fill in a value, this will be presented as a variable inventory_hostname during the play. You can modify the name of this Fact variable by changing the facts_hostname_var variable in my mysql.ini.

Relation between Hosts and Groups

The table hostgroups maps the relation between host and group using two FOREIGN KEYS.

Children

Groups can have other groups as children, use the table childgroups.

Note on Variables

This applies to host and group respectively. If no variables are needed either NULL it (actual MySQL NULL not the string) or use {}.
