build-dep support in dnf module

[keszybz]

ISSUE TYPE

• Feature Idea

COMPONENT NAME

module/dnf

SUMMARY

It'd be great if the dnf module supported build-dep installation like the apt module does (see 'build-dep' in description of state on http://docs.ansible.com/ansible/latest/apt_module.html).

Note that the absence of this feature also keeps the generic package layer from supporting build dependency installation, making it markedly less useful for setting up build servers.

Interim workaround for anyone else looking for the cross-platform functionality:

    - name: Install the build dependencies for OpenSSL and Python3 (Debian etc)
      apt:
        pkg: openssl, python3
        state: build-dep
      become: yes
      when: ansible_pkg_mgr == 'apt'

    - name: Install the build dependencies for OpenSSL and Python3 (Fedora etc)
      command:
        dnf builddep -y openssl python3
      args:
        warn: false
      register: dnf_result
      become: yes
      when: ansible_pkg_mgr == 'dnf'
      changed_when: '"Nothing to do" not in dnf_result.stdout'

Edit: improved dnf workaround to use the "Nothing to do" output to detect when nothing actually changed on the system.

Hi!

Thank you very much for your submission to Ansible. It sincerely means a lot to us that you've taken the time to contribute.

Per recent announcements at AnsibleFest Atlanta 2019, going forward we are no longer accepting new one off modules/plugins, or modules/plugins that create a new category.

However, we recommend looking into providing this functionality through Ansible Galaxy via Ansible Collections. You can find more information about collections at https://docs.ansible.co
m/ansible/devel/dev_guide/developing_collections.html.

Thank you once again for this and your interest in Ansible!

If you have further questions please stop by IRC or the mailing list:
