ansible.cfg

[defaults]
# (string) This setting controls how duplicate definitions of dictionary variables (aka hash, map, associative array) are handled in Ansible.
# This does not affect variables whose values are scalars (integers, strings) or arrays.
# **WARNING**, changing this setting is not recommended as this is fragile and makes your content (plays, roles, collections) non portable, leading to continual confusion and misuse. Don't change this setting unless you think you have an absolute need for it.
# We recommend avoiding reusing variable names and relying on the ``combine`` filter and ``vars`` and ``varnames`` lookups to create merged versions of the individual variables. In our experience this is rarely really needed and a sign that too much complexity has been introduced into the data structures and plays.
# For some uses you can also look into custom vars_plugins to merge on input, even substituting the default ``host_group_vars`` that is in charge of parsing the ``host_vars/`` and ``group_vars/`` directories. Most users of this setting are only interested in inventory scope, but the setting itself affects all sources and makes debugging even harder.
# All playbooks and roles in the official examples repos assume the default for this setting.
# Changing the setting to ``merge`` applies across variable sources, but many sources will internally still overwrite the variables. For example ``include_vars`` will dedupe variables internally before updating Ansible, with 'last defined' overwriting previous definitions in same file.
# The Ansible project recommends you **avoid ``merge`` for new projects.**
# It is the intention of the Ansible developers to eventually deprecate and remove this setting, but it is being kept as some users do heavily rely on it. New projects should **avoid 'merge'**.
