Well, this will be a really quick and straight-forward post about Ansible. 😀
You can save changes made of the iptables rules either directly from the command line or with a playbook. (Check my post on how to do that: “How we manage IPtables – now and then”.)
In order for the saved rules to be loaded automatically on boot we need: iptables-persistent package to be installed.
We can do that, pretty simple with an Ansible playbook:
- name: Install IPtables-persistent
apt:
name:
- iptables-persistent
update_cache: yes
state: present
With the task above, we can be sure that the iptables-persistent package, will be installed. You can check the Ansible documentation on what other choices you have with the parameter: state. One of the others parameters of the apt module is :
update_cache: yes
which is equivalent of
apt-get update
This can also be run as a separate task.
That was it. 🙂
