I am trying to list all installed packages on my Debian 7 (Wheezy), 8 (Jessie), and 9 (Stretch) 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 can I get the installed YUM packages with Ansible?

Since Ansible 2.5 you can use the package_facts module: ansible.builtin.package_facts module – Package information as facts

- 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 bootstrap).

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 }}"
