Ansible dynamic inventory is a feature in Ansible that allows you to generate inventory (host and group information) dynamically rather than statically defining it in a static inventory file. This dynamic approach is particularly useful in dynamic and cloud-based environments where the number and state of hosts can change frequently.
Inventory Sources: Ansible dynamic inventory sources are scripts or plugins that generate inventory data dynamically. These sources can fetch information from various sources like cloud providers, databases, or external systems.
Available sources:
Dynamic Generation: When you run Ansible commands or playbooks, Ansible executes the inventory source(s) to gather the current host and group information. This information is generated on the fly based on the current state of your infrastructure.
Flexible Configuration: Ansible allows you to configure dynamic inventory sources in your Ansible configuration files (ansible.cfg) or specify them on the command line using the -i option.
Dynamic inventory in Ansible is a powerful feature for managing infrastructure in dynamic and cloud-native environments, making it easier to automate configuration management and orchestration tasks.
