How to get the installed apt packages with Ansible?

问题

I am trying to list all installed packages on my Debian 7/8/9 machines. There are easy ways dealing with it using apt or dpkg but I could not find a proper way to do this with ansible out of the box.

Is there a nice and smooth way to do this?

For RHEL machines I found this Post: How to get the installed yum packages with Ansible?

It doesn't look like Ansible provides any modules that would support this. You'll have to use shell or command.

- name: Get packages
  shell: dpkg-query -f '${binary:Package}\n' -W
  register: packages

- name: Print packages
  debug:
    msg: "{{ packages.stdout_lines }}"

Since ansible 2.5 you can use the package_facts module: https://docs.ansible.com/ansible/latest/modules/package_facts_module.html

- name: Gather package facts
  package_facts:
    manager: auto

- name: Debug if package is present
  debug:
    msg: 'yes, mypackage is present'
  when: '"mypackage" in ansible_facts.packages'

- name: Debug if package is absent
  debug:
    msg: 'no, mypackage is absent'
  when: '"mypackage" not in ansible_facts.packages'

mind you, you need the ansible-apt module on debian for that (which is kindly provided by https://galaxy.ansible.com/robertdebock/bootstrap).
