Since it's been over a year, I forked this project and published an alternative to Galaxy. https://github.com/deekayen/al-agents-ansible-playbooks has a kludge, some updates, and Molecule testing until I can get Alert Logic to publish the GPG key so we can do a proper key import and/or validation task.

Something like this would probably be sufficient for RHEL 8/9:

In tasks/install_agent.yml:

    - name: Import Alert Logic Atlas GPG key.
      ansible.builtin.rpm_key:
        key: "{{ al_agent_gpg_key }}"
        fingerprint: "{{ al_agent_gpg_fingerprint }}"
        state: present
      when:
        - ansible_os_family == "RedHat"

In vars/RedHat.yml:

al_agent_gpg_key: "{{ al_agent_base_url }}/software/al-agent-pkg-key.asc"
al_agent_gpg_fingerprint: '9a2a3e9a817127b121b2b2fb00802f0e0186cc36'
