firewall

Manage firewall ports on all (known) Linux operating systems.

Example Playbook

This example is taken from molecule/resources/playbook.yml:

---
- name: Converge
  hosts: all
  become: yes
  gather_facts: yes

  roles:
    - robertdebock.firewall

The machine you are running this on, may need to be prepared.

---
- name: Prepare
  hosts: all
  gather_facts: no
  become: yes

  roles:
    - robertdebock.bootstrap

Also see a full explanation and example on how to use these roles.

Role Variables

These variables are set in defaults/main.yml:

---
# defaults file for firewall

# A list of service to allow traffic to.
firewall_services:
  - name: ssh

# A bit more difficult example:
# firewall_services:
#   - name: ssh
#   - name: https
#   - name: 5353
#     proto: udp

Testing

Unit tests are done on every commit, pull request, release and periodically.

If you find issues, please register them in GitHub

Testing is done using Tox and Molecule:

Tox tests multiple ansible versions. Molecule tests multiple distributions.

To test using the defaults (any installed ansible version, namespace: robertdebock, image: fedora, tag: latest):

molecule test

# Or select a specific image:
image=ubuntu molecule test
# Or select a specific image and a specific tag:
image="debian" tag="stable" tox

Or you can test multiple versions of Ansible, and select images: Tox allows multiple versions of Ansible to be tested. To run the default (namespace: robertdebock, image: fedora, tag: latest) tests:

tox

# To run CentOS (namespace: `robertdebock`, tag: `latest`)
image="centos" tox
# Or customize more:
image="debian" tag="stable" tox
