Magic
These variables cannot be set directly by the user; Ansible will always override them to reflect internal state.

ansible_check_mode
Boolean that indicates if we are in check mode or not

ansible_dependent_role_names

The names of the roles currently imported into the current play as dependencies of other plays

ansible_diff_mode

Boolean that indicates if we are in diff mode or not

ansible_forks

Integer reflecting the number of maximum forks available to this run

ansible_inventory_sources

List of sources used as inventory

ansible_limit

Contents of the --limit CLI option for the current execution of Ansible

ansible_loop

A dictionary/map containing extended loop information when enabled via loop_control.extended

ansible_loop_var

The name of the value provided to loop_control.loop_var. Added in 2.8

ansible_index_var

The name of the value provided to loop_control.index_var. Added in 2.9

ansible_parent_role_names

When the current role is being executed by means of an include_role or import_role action, this variable contains a list of all parent roles, with the most recent role (i.e. the role that included/imported this role) being the first item in the list. When multiple inclusions occur, this list lists the last role (i.e. the role that included this role) as the first item in the list. It is also possible that a specific role exists more than once in this list.
For example: When role A includes role B, inside role B, ansible_parent_role_names will equal to ['A']. If role B then includes role C, the list becomes ['B', 'A'].

ansible_parent_role_paths

When the current role is being executed by means of an include_role or import_role action, this variable contains a list of all parent roles, with the most recent role (i.e. the role that included/imported this role) being the first item in the list. Please refer to ansible_parent_role_names for the order of items in this list.

ansible_play_batch

ansible_playbook_python

ansible_role_names
