aws_security

Description

This cookbook provides libraries, resource and providers to config and manage Amazon EC2 Security Groups

Requirements

Testing Gems

• berkshelf
• test-kitchen
• kitchen-vagrant
• chefspec
• rspec_junit_formatter

Recipes

default

This recipe contains no resources as the fog-aws gem is now automatically installed by the resources as necessary.

Attributes

default['build-essential']['compile_time'] = true This must be set to true to ensure development tools are installed before the chef_gem 'fog-aws' is installed

default['aws_security']['encrypted_data_bag'] = nil Name of the data bag to search for your AWS credentials

default['aws_security']['aws_access_key_id'] = nil default['aws_security']['aws_secret_access_key'] = nil If these are defined, they will be used by default for the LWRPs

LWRPs

• aws_secret_access_key - required if aws_access_key_id is specified
• description - required
• vpcid - optional
• region - optional (defaults to 'us-east-1')

Usage

aws_security_group 'Example' do
  description "Example Security Group"
  aws_access_key_id node['aws_security']['aws_access_key_id']
  aws_secret_access_key node['aws_security']['aws_secret_access_key']
  region 'us-west-2'
end

aws_security_group_rule

• aws_secret_access_key - required
• groupname - optional
• description - optional
• vpcid - optional
• region - optional (defaults to 'us-east-1')
• groupid - optional
• groupname - optional
• cidr_ip - optional
• group - optional
• owner - optional
• ip_protocol - optional, (must be one of the following [-1,udp,tcp,icmp])
• port_range - optional (port..port)
• from_port - optional
• to_port - optional

Usage

The following will create a rule in security group Example in region us-west-2 to allow 192.168.1.1 access to port 80

aws_security_group_rule 'example1' do
  description "Example Rule 1"
  aws_access_key_id node['aws_security']['aws_access_key_id']
  aws_secret_access_key node['aws_security']['aws_secret_access_key']
  cidr_ip "192.168.1.1/32"
  groupname "Example"
  region 'us-west-2'
  port_range "80..80"
  ip_protocol 'tcp'
end

The following will create a rule in security group Example in region us-west-2 to allow a security group with the id of sg-3b5a6ffe to allow access to port 80

aws_security_group_rule 'exmaple2' do
  description "Example Rule 2"
  aws_access_key_id node['aws_security']['aws_access_key_id']
  aws_secret_access_key node['aws_security']['aws_secret_access_key']
  group "sg-3b5a6ffe"
  groupname "Example"
  region 'us-west-2'
  port_range "80..80"
  ip_protocol 'tcp'
end

The following will create a rule in security group Example in region us-east-1 to allow 10.0.0.0/24 all access

aws_security_group_rule 'example3' do
  description "Example Rule 3"
  aws_access_key_id node['aws_security']['aws_access_key_id']
  aws_secret_access_key node['aws_security']['aws_secret_access_key']
  cidr_ip "10.0.0.0/24"
  groupname "Example"
  ip_protocol '-1'
end

TODO

• Egress rules
• Apply security groups to instances, elbs, vpcs, etc

AWS Credentials for testing

The default testing recipe will look for a encrypted data bag item aws_keys in the data bag defined by node['aws_security']['encrypted_data_bag'] with the following keys:

• aws_access_key_id
• aws_secret_access_key

E.G.

{
    "id": "aws_keys",
    "aws_access_key_id": "YOUR_ACCESS_KEY",
    "aws_secret_access_key": "YOUR_SECRET_ACCESS_KEY"
}
