I'm currently building a role for installing PHP using ansible, and I'm having some difficulty merging dictionaries. I've tried several ways to do so, but I can't get it to work like I want it to:
# A vars file: my_default_values: key = value my_values: my_key = my_value # In a playbook, I create a task to attempt merging the # two dictionaries (which doesn't work): - debug: msg="{{ item.key }} = {{ item.value }}" with_dict: my_default_values + my_values # I have also tried: - debug: msg="{{ item.key }} = {{ item.value }}" with_dict: my_default_values|union(my_values) # I have /some/ success with using j2's update, # but you can't use j2 syntax in "with_dict", it appears. # This works: - debug: msg="{{ my_default_values.update(my_values) }}" # But this doesn't: - debug: msg="{{ item.key }} = {{ item.value }}" with_dict: my_default_values.update(my_values) Is there a way to merge two dictionaries, so I can use it with "with_dict"?

If you have two or more lists of dictionaries and want to combine them into a list of merged dictionaries, where the dictionaries are merged by an attribute, you can use the lists_mergeby filter. The output of the examples in this section use the YAML callback plugin.
You can merge two dictionaries using the | operator. It is a very convenient method to merge dictionaries; however, it is only used in the python 3.9 version or more.
Using | in Python 3.9 In the latest update of python now we can use “|” operator to merge two dictionaries. It is a very convenient method to merge dictionaries.
In Ansible 2.0, there is a Jinja filter, combine, for this:
- debug: msg="{{ item.key }} = {{ item.value }}" with_dict: "{{ my_default_values | combine(my_values) }}" If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
