how to read json file using ansible

In case if you need to read a JSON formatted text and store it as a variable, it can be also handled by include_vars .

- hosts: localhost
  tasks:
    - include_vars:
        file: variable-file.json
        name: variable

    - debug: var=variable

You have to add a from_json jinja2 filter after the lookup:

version_file: "{{ lookup('file','/home/shasha/devOps/tests/packageFile.json') | from_json }}"
