Extending the previous YAML inventory to include what, when, and where would look like: You can see that one.example.com exists in the dbservers, east, and prod groups. The inventories I'm a freelance frontend Drupal dev and my tech stack is typical (sprawling) … Default to the dynamic inventory.

Once your inventory is defined, you use patterns to select the hosts or groups you want Ansible to run against. separate environments, like staging and production, at the same time for a specific action. Aggregating inventory sources with a directory. are merged in ASCII order according to the filenames so the result can An alias declared in inventory file can be used in the same way as a host. their location.
