Credentials

In order to manage AWS components, authentication credentials need to be available to the node. There are 3 ways to handle this:

explicitly pass credentials parameter to the resource
use the credentials in the ~/.aws/credentials file
let the resource pick up credentials from the IAM role assigned to the instance

Also new resources can now assume an STS role, with support for MFA as well. Instructions are below in the relevant section.

Using resource parameters

In order to pass the credentials to the resource, credentials must be available to the node. There are a number of ways to handle this, such as node attributes applied to the node or via Chef roles/environments.

We recommend storing these in an encrypted databag, and loading them in the recipe where the resources are used.

Example Data Bag:

% knife data bag show aws main
{
  "id": "main",
  "aws_access_key_id": "YOUR_ACCESS_KEY",
  "aws_secret_access_key": "YOUR_SECRET_ACCESS_KEY",
  "aws_session_token": "YOUR_SESSION_TOKEN"
}

This can be loaded in a recipe with:

aws = data_bag_item('aws', 'main')

And to access the values:

aws['aws_access_key_id']
aws['aws_secret_access_key']
aws['aws_session_token']

We'll look at specific usage below.

Using local credentials

If credentials are not supplied via parameters, resources will look for the credentials in the ~/.aws/credentials file:

[default]
aws_access_key_id = ACCESS_KEY_ID
aws_secret_access_key = ACCESS_KEY

Note that this also accepts other profiles if they are supplied via the ENV['AWS_PROFILE'] environment variable.

Using IAM instance role

If your instance has an IAM role, then the credentials can be automatically resolved by the cookbook using Amazon instance metadata API.

You can then omit the resource parameters aws_secret_access_key and aws_access_key.

Of course, the instance role must have the required policies. Here is a sample policy for EBS volume management:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Action": [
        "ec2:AttachVolume",
        "ec2:CreateVolume",
        "ec2:ModifyInstanceAttribute",
        "ec2:ModifyVolumeAttribute",
        "ec2:DescribeVolumeAttribute",
        "ec2:DescribeVolumeStatus",
        "ec2:DescribeVolumes",
        "ec2:DetachVolume",
        "ec2:EnableVolumeIO"
      ],
      "Sid": "Stmt1381536011000",
      "Resource": [
        "*"
      ],
      "Effect": "Allow"
    }
  ]
}

For resource tags:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Action": [
        "ec2:CreateTags",
        "ec2:DescribeTags"
      ],
      "Sid": "Stmt1381536708000",
      "Resource": [
        "*"
      ],
      "Effect": "Allow"
    }
  ]
}

Assuming roles via STS and using MFA

The following is an example of how roles can be assumed using MFA. The following can also be used to assumes roles that do not require MFA, just ensure that the MFA arguments (serial_number and token_code) are omitted.

This assumes you have also stored the cfn_role_arn, and mfa_serial attributes as well, but there are plenty of ways these attributes can be supplied (they could be stored locally in the consuming cookbook, for example).

Note that MFA codes cannot be recycled, hence the importance of creating a single STS session and passing that to resources. If multiple roles need to be assumed using MFA, it is probably prudent that these be broken up into different recipes and chef-client runs.

require 'aws-sdk'
require 'securerandom'

session_id = SecureRandom.hex(8)
sts = ::Aws::AssumeRoleCredentials.new(
  client: ::Aws::STS::Client.new(
    credentials: ::Aws::Credentials.new(
      node['aws']['aws_access_key_id'],
      node['aws']['aws_secret_access_key']
    ),
    region: 'us-east-1'
  ),
  role_arn: node['aws']['cfn_role_arn'],
  role_session_name: session_id,
  serial_number: node['aws']['mfa_serial'],
  token_code: node['aws']['mfa_code']
)

aws_cloudformation_stack 'kitchen-test-stack' do
  action :create
  template_source 'kitchen-test-stack.tpl'
  aws_access_key sts.access_key_id
  aws_secret_access_key sts.secret_access_key
  aws_session_token sts.session_token
end

When running the cookbook, ensure that an attribute JSON is passed that supplies the MFA code. Example using chef-zero:

echo '{ "aws": { "mfa_code": "123456" } }' > mfa.json && chef-client -z -o 'recipe[aws_test]' -j mfa.json

Running outside of an AWS instance

region can be specified if the cookbook is being run outside of an AWS instance. This can prevent some kinds of failures that happen when resources try to detect region.

aws_cloudformation_stack 'kitchen-test-stack' do
  action :create
  template_source 'kitchen-test-stack.tpl'
  region 'us-east-1'
end

Recipes

default.rb

This recipe is empty and should not be included on a node run_list

ec2_hints.rb

This recipe is used to setup the EC2 hints for Ohai in the case that an instance is not created using knife-ec2. When using recent Chef 12 releases this is no longer necessary as Ohai detects EC2 without hint files.

Properties:

aws_secret_access_key, aws_access_key and optionally aws_session_token - passed to Opscode::AWS:Ec2 to authenticate, required, unless using IAM roles for authentication.

aws_ebs_volume

The resource only handles manipulating the EBS volume, additional resources need to be created in the recipe to manage the attached volume as a filesystem or logical volume.

aws_ebs_volume 'db_ebs_volume' do
  aws_access_key aws['aws_access_key_id']
  aws_secret_access_key aws['aws_secret_access_key']
  size 50
  device '/dev/sdi'
  action [:create, :attach]
end

This will create a 50G volume, attach it to the instance as /dev/sdi.

aws_ebs_volume 'db_ebs_volume_from_snapshot' do
  aws_access_key aws['aws_access_key_id']
  aws_secret_access_key aws['aws_secret_access_key']
  size 50
  device '/dev/sdi'
  snapshot_id 'snap-ABCDEFGH'
  action [:create, :attach]
end

This will create a new 50G volume from the snapshot ID provided and attach it as /dev/sdi.

aws_elastic_ip

The elastic_ip resource provider does not support allocating new IPs. This must be done before running a recipe that uses the resource. After allocating a new Elastic IP, we recommend storing it in a databag and loading the item in the recipe.

Example:

aws_elastic_ip 'eip_load_balancer_production' do
  aws_access_key aws['aws_access_key_id']
  aws_secret_access_key aws['aws_secret_access_key']
  ip ip_info['public_ip']
  action :associate
end

aws_elastic_lb

elastic_lb functions similarly to elastic_ip. Make sure that you've created the ELB and enabled your instances' availability zones prior to using this provider.

Example:

To register the node in the 'QA' ELB:

aws_elastic_lb 'elb_qa' do
  aws_access_key aws['aws_access_key_id']
  aws_secret_access_key aws['aws_secret_access_key']
  name 'QA'
  action :register
end

aws_resource_tag

resource_tag can be used to manipulate the tags assigned to one or more AWS resources, i.e. ec2 instances, EBS volumes or EBS volume snapshots.

Examples:

Assigning tags to a node to reflect its role and environment:

aws_resource_tag node['ec2']['instance_id'] do
  aws_access_key aws['aws_access_key_id']
  aws_secret_access_key aws['aws_secret_access_key']
  tags('Name' => 'www.example.com app server',
       'Environment' => node.chef_environment)
  action :update
end

Assigning a set of tags to multiple resources, e.g. ebs volumes in a disk set:

aws_resource_tag 'my awesome raid set' do
  aws_access_key aws['aws_access_key_id']
  aws_secret_access_key aws['aws_secret_access_key']
  resource_id ['vol-d0518cb2', 'vol-fad31a9a', 'vol-fb106a9f', 'vol-74ed3b14']
  tags('Name' => 'My awesome RAID disk set',
       'Environment' => node.chef_environment)
end

aws_resource_tag 'db_ebs_volume' do
  resource_id lazy { node['aws']['ebs_volume']['db_ebs_volume']['volume_id'] }
  tags ({ 'Service' => 'Frontend' })
end

aws_s3_file

s3_file can be used to download a file from s3 that requires aws authorization. This is a wrapper around the core chef remote_file resource and supports the same resource attributes as remote_file. See [remote_file Chef Docs] (https://docs.chef.io/resource_remote_file.html) for a complete list of available attributes.

Example:

aws_s3_file '/tmp/foo' do
  bucket 'i_haz_an_s3_buckit'
  remote_path 'path/in/s3/bukket/to/foo'
  aws_access_key aws['aws_access_key_id']
  aws_secret_access_key aws['aws_secret_access_key']
  region 'us-west-1'
end

aws_secondary_ip

The secondary_ip resource provider allows one to assign/un-assign multiple private secondary IPs on an instance in EC2-VPC. The number of secondary IP addresses that you can assign to an instance varies by instance type. If no ip address is provided on assign, a random one from within the subnet will be assigned. If no interface is provided, the default interface (which is pulled from Ohai) will be used.

Example:

aws_secondary_ip "assign_additional_ip" do
  aws_access_key aws['aws_access_key_id']
  aws_secret_access_key aws['aws_secret_access_key']
  ip ip_info['private_ip']
  interface 'eth0'
  action :assign
end

aws_cloudformation_stack

Manage CloudFormation stacks.

Actions:

create: Creates the stack, or updates it if it already exists.
delete: Begins the deletion process for the stack.

Properties:

template_source: Required - the location of the CloudFormation template file. The file should be stored in the files directory in the cookbook.
parameters: An array of parameter_key and parameter_value pairs for parameters in the template. Follow the syntax in the example above.
disable_rollback: Set this to true if you want stack rollback to be disabled if creation of the stack fails. Default: false
stack_policy_body: Optionally define a stack policy to apply to the stack, mainly used in protecting stack resources after they are created. For more information, see Prevent Updates to Stack Resources in the CloudFormation user guide.
iam_capability: Set to true to allow the CloudFormation template to create IAM resources. This is the equivalent of setting CAPABILITY_IAM When using the SDK or CLI. Default: false

Example:

aws_cloudformation_stack 'example-stack' do
  region 'us-east-1'
  template_source 'example-stack.tpl'

  parameters ([
    {
      :parameter_key => 'KeyPair',
      :parameter_value => 'user@host'
    },
    {
      :parameter_key => 'SSHAllowIPAddress',
      :parameter_value => '127.0.0.1/32'
    }
  ])
end

aws_dynamodb_table

Use this resource to create and delete DynamoDB tables. This includes the ability to add global secondary indexes to existing tables.

Actions:

create: Creates the table. Will update the following if the table exists:
- global_secondary_indexes: Will remove non-existent indexes, add new ones, and update throughput for existing ones. All attributes need to be present in attribute_definitions. No effect if the resource is omitted.
- stream_specification: Will update as shown. No effect is the resource is omitted.
- provisioned_throughput: Will update as shown.
delete: Deletes the index.

Properties:

attribute_definitions: Required. Attributes to create for the table. Mainly this is used to specify attributes that are used in keys, as otherwise one can add any attribute they want to a DynamoDB table.
key_schema: Required. Used to create the primary key for the table. Attributes need to be present in attribute_definitions.
local_secondary_indexes: Used to create any local secondary indexes for the table. Attributes need to be present in attribute_definitions.
global_secondary_indexes: Used to create any global secondary indexes. Can be done to an existing table. Attributes need to be present in
attribute_definitions.
provisioned_throughput: Define the throughput for this table.
stream_specification: Specify if there should be a stream for this table.

Several of the attributes shown here take parameters as shown in the AWS Ruby SDK Documentation. Also, the AWS DynamoDB Documentation may be of further help as well.
