In Ansible, to restrict access for different user groups to various servers, a combination of inventory, roles, and access control mechanisms at the infrastructure and management tool levels are typically used.
Main approaches:
-
Segmentation of inventory by server groups — create different inventory files or groups within a single inventory, for example
[webservers],[dbservers]. -
Using ansible.cfg and environment variables — for each user or group, configure a separate configuration file specifying the inventory and restrictions.
-
Roles and playbooks with restrictions — explicitly specify in playbooks which server groups the task applies to.
-
Access control via version control systems and CI/CD — restrict rights to run certain playbooks or access the inventory.
-
Using Ansible Tower / AWX — these tools provide built-in RBAC (Role-Based Access Control), where you can configure which users or groups can run playbooks on which inventories.
Example inventory structure:
[webservers]
web1.example.com
web2.example.com
[dbservers]
db1.example.com
[webadmins:children]
webservers
[dbadmins:children]
dbservers
Then, in Ansible Tower, you can assign the user group webadmins with access only to the webservers group.
If only CLI is used, different inventories and permissions can be organized at the OS level so that users only have access to their respective inventories.
