ansible Ansible group variables Group variables with static inventory
Example
It is suggested that you define groups based on purpose of the host (roles) and also geography or datacenter location (if applicable):
File inventory/production
[rogue-server]
192.168.1.1
[atlanta-webservers]
www-atl-1.example.com
www-atl-2.example.com
[boston-webservers]
www-bos-1.example.com
www-bos-2.example.com
[atlanta-dbservers]
db-atl-1.example.com
db-atl-2.example.com
[boston-dbservers]
db-bos-1.example.com
# webservers in all geos
[webservers:children]
atlanta-webservers
boston-webservers
# dbservers in all geos
[dbservers:children]
atlanta-dbservers
boston-dbservers
# everything in the atlanta geo
[atlanta:children]
atlanta-webservers
atlanta-dbservers
# everything in the boston geo
[boston:children]
boston-webservers
boston-dbservers
File group_vars/all
---
apache_port: 80
File group_vars/atlanta-webservers
---
apache_port: 1080
File group_vars/boston-webservers
---
apache_port: 8080
File host_vars/www-bos-2.example.com
---
apache_port: 8111
After running ansible-playbook -i inventory/hosts install-apache.yml (hosts in the playbook would be hosts: all)
The ports would be
| Address | Port |
|---|---|
192.168.1.1 | 80 |
www-atl-1.example.com | 1080 |
www-atl-2.example.com | 1080 |
www-bos-1.example.com | 8080 |
www-bos-2.example.com | 8111 |
