ansible - example of looping yum packages with different setting for one of them

old.yml

- name: Install the required rpms
  yum: name={{ item }} state=latest
  with_items:
      - wget
      - git
      - net-tools
      - bind-utils
      - iptables-services
      - bridge-utils
      - bash-completion
      - docker
      - python-httplib2  => ignore checking package signature

possible_untested.yml

- name: Install the required rpms
  yum: 
    name: "{{ (item is mapping)|ternary(item.name, item) }}"
    gpcheck: "{{ (item is mapping)|ternary(item.gpgcheck, default(omit)) }}"
    state: latest
  with_items:
    - wget
    - git
    - net-tools
    - bind-utils
    - iptables-services
    - bridge-utils
    - bash-completion
    - docker
    - { name: python-httplib2, gpgcheck: no }

suggested.yml

- name: Install the required rpms
  yum: 
    name: "{{ item.name }}"
    gpcheck: "{{ item.gpgcheck|default(omit) }}"
    state: latest
  with_items:
    - { name: wget }
    - { name: git }
    - { name: net-tools }
    - { name: bind-utils }
    - { name: iptables-services }
    - { name: bridge-utils }
    - { name: bash-completion }
    - { name: docker }
    - { name: python-httplib2, gpgcheck: no }

Are you sure it works ??Would you mind giving me some hints? Here is my test,
$ ansible-playbook test8.yml
/usr/lib/python2.7/site-packages/cryptography/init.py:39: CryptographyDeprecationWarning: Python 2 is no longer supported by the Python core team. Support for it is now deprecated in cryptography, and will be removed in a future release.

Hello, these examples were for ansible pre loop: syntax and yes the suggested approach should definitely work. The untested one, well, it was untested but in theory it should be possible. Your error item is undefined implies that your task is not configured correctly to loop - check your ansible version, check the loop docs, and make sure your indentation is correct - it looks to me like your yum module keys are not indented correctly.
