Ansible. override single dictionary key

In Ansible, you can override a single key within a dictionary by using the combine filter with a dictionary containing only the key you want to override. Here's how you can achieve this:

Let's say you have an original dictionary like this:

original_dict: key1: value1 key2: value2 key3: value3

And you want to override key2 with a new value:

- name: Override a single key in a dictionary hosts: localhost tasks: - name: Define the override dictionary set_fact: override_dict: key2: new_value2 - name: Combine the dictionaries to override a single key set_fact: combined_dict: "{{ original_dict | combine(override_dict) }}" - debug: var: combined_dict

In this example, the set_fact task defines the override_dict with only the key you want to override. Then, the combine filter is used to merge the original dictionary with the override_dict, effectively overriding the specified key.

After running this playbook, the combined_dict variable will contain the updated dictionary with the overridden value:

combined_dict: key1: value1 key2: new_value2 key3: value3

This approach allows you to update a single key within a dictionary while keeping the rest of the dictionary unchanged.
