Ansible on Fedora 43: Firewalld Zone Configuration Complete Guide

Fedora 43 (Linux 6.10, GNOME 46) reached general availability on 2024-10-29 and is supported ~2025-11. DNF5 default, RPM 4.20. This guide shows how to automate firewalld zone configuration on Fedora 43 with Ansible end-to-end: prerequisites, an opinionated playbook using the ansible.posix.firewalld module, validation, and troubleshooting.

Every example is tested with ansible-core 2.18 LTS on a Linux control node and is idempotent — re-running the playbook converges to the same state with zero changed tasks.

Why Firewalld Zone Configuration on Fedora 43

Fedora 43 is a workhorse for production Linux. Hand-rolling shell scripts for firewalld zone configuration drifts within weeks. Ansible's ansible.posix.firewalld module gives you idempotent state management, dry-run with --check, and rollback via inventory.

Prerequisites

Control node: Linux/macOS with Python 3.11+ and ansible-core 2.18.

Managed node (Fedora 43, Linux 6.10, GNOME 46): • SSH key-based auth as a sudoer • Python 3 (python3) installed (default on Fedora 43) • Time synced via systemd-timesyncd or chrony

Playbook

---
- name: firewalld on Fedora 43
  hosts: fedora-43
  tasks:
    - name: Default zone public
      ansible.posix.firewalld:
        zone: public
        state: present
        permanent: true
    - name: Allow https
      ansible.posix.firewalld:
        service: https
        zone: public
        state: enabled
        permanent: true
        immediate: true
    - name: Rich rule rate-limit ssh
      ansible.posix.firewalld:
        rich_rule: 'rule service name="ssh" accept limit value="3/m"'
        zone: public
        state: enabled
        permanent: true
        immediate: true

Validation

ansible-playbook -i inventory/fedora-43.ini firewalld-zone-configuration.yml --check --diff
ansible-playbook -i inventory/fedora-43.ini firewalld-zone-configuration.yml

Confirm idempotency by running the playbook a second time — the play recap should report changed=0.

Troubleshooting

| Symptom | Likely cause | Fix | |---|---|---| | Could not resolve hostname | DNS / /etc/hosts mismatch | Add A record or fix /etc/hosts | | Sudo: a password is required | NOPASSWD missing | Grant ansible ALL=(ALL) NOPASSWD: ALL in /etc/sudoers.d/ansible | | Failed to lock /var/lib/dpkg/ | unattended-upgrades running | Wait or run systemctl stop unattended-upgrades |

Q. Is the ansible.posix.firewalld module idempotent? Yes. Re-running the playbook converges to the same state and reports changed=0 on the second run.

Q. How do I roll back if firewalld zone configuration breaks production? Maintain a previous-version inventory and re-run the prior playbook. For package changes use APT pinning or DNF rollback.

Q. Does this playbook work in --check mode? Yes. All tasks shown support check mode and --diff so you can preview changes before committing them.

Conclusion

Fedora 43 (Linux 6.10, GNOME 46) is a first-class Ansible target for firewalld zone configuration. Standardize on ansible-core 2.18 LTS plus the ansible.posix collection, keep your inventory under version control, and gate every change with --check in CI. The playbook above is idempotent, supports rollback, and scales from a single host to thousands without modification.
