Sets up iptables to use a script to maintain firewall rules. However this cookbook may be deprecated or heavily modified in favor of the general firewall cookbook, see Roadmap.
- [COOK-652] - create a firewall cookbook
- [COOK-688] - create iptables providers for all resources
The default recipe will install iptables and provides a perl script
/usr/sbin/rebuild-iptables) to manage rebuilding
firewall rules from files dropped off in
See Roadmap for plans to replace the definition with LWRPs.
The definition drops off a template in
/etc/iptables.d after the
name parameter. The rule will get added to the local system firewall
through notifying the
rebuild-iptables script. See Examples below.
Ensure that the system is set up to use the definition and rebuild
recipe[iptables]. Then create templates with the
firewall rules in the cookbook where the definition will be used. See
To enable port 80, e.g. in an
httpd cookbook, create the following
# Port 80 for http -A FWR -p tcp -m tcp --dport 80 -j ACCEPT
This would go in the cookbook,
httpd/templates/default/http.erb. Then to use it in
