Ansible on Fedora 45 Automation Complete Guide

Fedora 45 is scheduled for late 2026 and previews kernel 6.16, Python 3.14, GNOME 49, Podman 5.5, OpenSSH 10.0, and dnf5. It is the upstream baseline for RHEL 11 features. This guide covers the Ansible automation patterns that work today on Fedora 45 lab and developer systems.

Ansible-core compatibility

Use ansible-core 2.20 or later. Python 3.14 on managed nodes requires ansible-core ≥ 2.19.

Podman 5.5 with Quadlet

- name: Quadlet rollout on F45
  hosts: fedora45
  become: true
  tasks:
    - name: Drop quadlet
      ansible.builtin.copy:
        dest: /etc/containers/systemd/api.container
        mode: "0644"
        content: |
          [Container]
          Image=quay.io/corp/api:1.4.2
          PublishPort=8443:8443
          Volume=api-data.volume:/var/lib/api
          [Install]
          WantedBy=default.target
    - ansible.builtin.systemd: { daemon_reload: true }
    - ansible.builtin.systemd: { name: api, enabled: true, state: started }

systemd-soft-reboot patching

- name: Soft-reboot patch loop
  hosts: fedora45
  become: true
  tasks:
    - name: Updates
      ansible.builtin.dnf5: { name: "*", state: latest }
    - name: Soft reboot
      ansible.builtin.command: systemctl soft-reboot
      async: 30
      poll: 0
    - name: Wait for SSH
      ansible.builtin.wait_for_connection: { delay: 10, timeout: 120 }

Best practices

• Validate playbooks against Python 3.14 deprecations (python -W error). • Use Quadlet over docker-compose — the unit files survive reboots and integrate with systemctl. • Pin GNOME extension versions if managing developer desktops fleet-wide.

Conclusion

Fedora 45 is a small but meaningful step from F44: kernel 6.16, Podman 5.5, Python 3.14. Ansible playbooks that use dnf5 and Quadlet on F44 work unchanged.

Installing Ansible on Fedora 45

# Install via DNF
sudo dnf install ansible-core -y
# Or the full package
sudo dnf install ansible -y
# Verify
ansible --version

FAQ

What is the difference between Fedora 45 and Fedora 46?

Fedora releases every ~6 months. Fedora 46 includes newer kernel, updated packages, and potentially new default tools. Ansible playbooks generally work across Fedora versions with minimal changes.

Should I use Podman or Docker on Fedora?

Fedora ships Podman by default as a rootless, daemonless container engine. Podman is recommended for Fedora. Use containers.podman.podman_container for Ansible automation.
