Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

Description

Provides a set of primitives for managing firewalls and associated rules.

PLEASE NOTE - The resource/providers in this cookbook are under heavy development. An attempt is being made to keep the resource simple/stupid by starting with less sophisticated firewall implementations first and refactor/vet the resource definition with each successive provider.

Requirements

Platform

  • Ubuntu

Tested on:

  • Ubuntu 10.04
  • Ubuntu 11.04

Resources/Providers

firewall

Actions

  • :enable: enable the firewall. this will make any rules that have been defined 'active'.
  • :disable: disable the firewall. drop any rules and put the node in an unprotected state.
  • :reset: reset the firewall. drop any rules and puts the node in the default state. Does not enable or disable the firewall.

Attribute Parameters

  • name: name attribute. arbitrary name to uniquely identify this resource

Providers

  • Chef::Provider::Firewall::Ufw
    • platform default: Ubuntu

Examples

# enable platform default firewall
firewall "ufw" do
  action :enable
end

firewall_rule

Actions

  • :allow: the rule should allow incoming traffic.
  • :deny: the rule should deny incoming traffic.
  • :reject: the rule should reject incoming traffic.

Attribute Parameters

  • name: name attribute. arbitrary name to uniquely identify this firewall rule
  • protocol: valid values are: :udp, :tcp. default is all protocols
  • port: incoming port number (ie. 22 to allow inbound SSH)
  • source: ip address or subnet to filter on incoming traffic. default is 0.0.0.0/0 (ie Anywhere)
  • destination: ip address or subnet to filter on outgoing traffic.
  • dest_port: outgoing port number.
  • position: position to insert rule at. if not provided rule is inserted at the end of the rule list.

Providers

  • Chef::Provider::FirewallRule::Ufw
    • platform default: Ubuntu

Examples

# open standard ssh port, enable firewall
firewall_rule "ssh" do
  port 22
  action :allow
  notifies :enable, "firewall[ufw]"
end

# open standard http port to tcp traffic only; insert as first rule
firewall_rule "http" do
  port 80
  protocol :tcp
  position 1
  action :allow
end

firewall "ufw" do
  action :nothing
end
