Each variable in the name is expanded to create a cartesian product of all possible layer combinations. - The C(parents) are a list of parent groups that the host belongs to. Each C(parent) item contains a C(name) key, again expanded from the template, and an optional C(parents) key that lists its parents. - Parents can also contain C(vars), which is a dictionary of vars that is then always set for that variable. This can provide easy access to the group name. E.g set an C(application) variable that is set to the value of the C(application) layer name. layers: description: - A dictionary of layers, with the key being the layer name, used as a variable name in the C(host) C(name) and C(parents) keys. Each layer value is a list of possible values for that layer. a # inventory.config file in YAML format # remember to enable this inventory plugin in the ansible.cfg before using # View the output using `ansible-inventory -i inventory.config --list` plugin: ansible.builtin.generator hosts: name: "{{ operation }}_{{ application }}_{{ environment }}_runner" parents: - name: "{{ operation }}_{{ application }}_{{ environment }}" parents: - name: "{{ operation }}_{{ application }}" parents: - name: "{{ operation }}" - name: "{{ application }}" - name: "{{ application }}_{{ environment }}" parents: - name: "{{ application }}" vars: application: "{{ application }}" - name: "{{ environment }}" vars: environment: "{{ environment }}" - name: runner layers: operation: - build - launch environment: - dev - test - prod application: - web - api N)product) constants)AnsibleParserError)BaseInventoryPlugincHeZdZdZdZfdZfdZdZdZdfd Z xZ S) InventoryModulez> constructs groups and vars using Jinja2 template expressions generatorc*tt| yN)superr __init__)self __class__s S/home/dcms/DCMS/lib/python3.12/site-packages/ansible/plugins/inventory/generator.pyrzInventoryModule.__init__Ws ot-/cd}tt| |rrYs9# >" H "-94a)4ar
