Credentials

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

  1. Explicitly set the credentials when using the resources
  2. Use the credentials in the ~/.aws/credentials file
  3. 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 authentication properties aws_secret_access_key and aws_access_key when using the resource.

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 on each resource 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

Resources

  • timeout - connection timeout for EC2 API.
  • snapshots_to_keep - used with action :prune for number of snapshots to maintain.
  • description - used to set the description of an EBS snapshot
  • volume_type - "standard", "io1", or "gp2" ("standard" is magnetic, "io1" is provisioned SSD, "gp2" is general purpose SSD)
  • piops - number of Provisioned IOPS to provision, must be >= 100
  • existing_raid - whether or not to assume the raid was previously assembled on existing volumes (default no)

end

aws_elastic_ip 'Server public IP' do
  ip '34.15.30.11'
  action :associate
end

aws_elastic_lb

elastic_lb handles registering and removing nodes from ELBs. The resource also adds basic support for creating and deleting ELBs. Note that currently this resource is not fully idempotent so it will not update the existing configuration of an ELB.

aws_resource_tag node['ec2']['instance_id'] do
  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
  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_route53_record

Actions:

  • create - Create a Route53 record

  • value String Array - value appropriate to the type.. for type 'A' value would be an IP address in IPv4 format for example.
  • type Required. String DNS record type
  • ttl Integer default: 3600 - time to live, the amount of time in seconds to cache information about the record
  • weight Optional. String. - a value that determines the proportion of DNS queries that will use this record for the response. Valid options are between 0-255. NOT CURRENTLY IMPLEMENTED
  • set_identifier Optional . String. - a value that uniquely identifies record in the group of weighted record sets
  • geo_location String.
  • geo_location_country String
  • geo_location_continent String
  • geo_location_subdivision String

  • overwrite [true, false] default: true
  • alias_target Optional. Hash. - Associated with Amazon 'alias' type records. The hash contents varies depending on the type of target the alias points to.
  • mock [true, false] default: false
  • fail_on_error [true, false] default: false

Examples:

Create a simple record

route53_record "create a record" do
  name  "test"
  value "16.8.4.2"
  type  "A"
  weight "1"
  set_identifier "my-instance-id"
  zone_id "ID VALUE"
  overwrite true
  fail_on_error false
  action :create
end

Delete an existing record. Note that value is still necessary even though we're deleting. This is a limitation in the AWS SDK.

aws_route53_record "delete a record" do
  name  "test"
  value "16.8.4.2"
  type 'A'
  value '123'
  action :delete
end

aws_route53_zone

Actions:

  • create - Create a Route53 zone
  • delete - Remove a Route53 zone

Properties:

  • aws_secret_access_key, aws_access_key and optionally aws_session_token - required, unless using IAM roles for authentication.
  • name Required. String. - name of the zone.
  • description String. - Description shown in the Route53 UI
  • private [true, false]. default: false - Should this be a private zone for use in your VPCs or a Public zone
  • vpc_id String. If creating a Private zone this is the VPC to associate the zone with.

Examples:

aws_route53_zone 'testkitchen.dmz' do
  description 'My super important zone'
  action :create
end

aws_secondary_ip.rb

This feature is available only to instances within VPCs. It allows you to assign multiple private IP addresses to a network interface.

Actions:

  • assign - Assign a private IP to the instance.
  • unassign - Unassign a private IP from the instance.

Properties:

  • aws_secret_access_key, aws_access_key and optionally aws_session_token - required, unless using IAM roles for authentication.
  • ip - the private IP address. - required.
  • interface - the network interface to assign the IP to. If none is given, uses the default interface.
  • timeout - connection timeout for EC2 API.

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.

Properties:

  • aws_secret_access_key, aws_access_key and optionally aws_session_token - required, unless using IAM roles for authentication.
  • region - The AWS region containing the file. Default: The current region of the node when running in AWS or us-east-1 if the node is not in AWS.

Actions:

  • create: Downloads a file from s3
  • create_if_missing: Downloads a file from S3 only if it doesn't exist locally
  • delete: Deletes a local file
  • touch: Touches a local file

Examples:

aws_s3_file '/tmp/foo' do
  bucket 'i_haz_an_s3_buckit'
  remote_path 'path/in/s3/bukket/to/foo'
  region 'us-west-1'
end
aws_s3_file '/tmp/bar' do
  bucket 'i_haz_another_s3_buckit'
  remote_path 'path/in/s3/buckit/to/foo'
  region 'us-east-1'
  requester_pays true
end

aws_s3_bucket

s3_bucket can be used to create or delete S3 buckets. Note that buckets can only be deleted if they are empty unless you specify delete_all_objects true, which will delete EVERYTHING in your bucket first.

Actions:

  • create: Creates the bucket
  • delete: Deletes the bucket

Properties:

  • aws_secret_access_key, aws_access_key and optionally aws_session_token - required, unless using IAM roles for authentication.
  • region - The AWS region containing the bucket. Default: The current region of the node when running in AWS or us-east-1 if the node is not in AWS.
  • versioning - Enable or disable S3 bucket versioning. Default: false
  • delete_all_objects - Used with the :delete action to delete all objects before deleting a bucket. Use with EXTREME CAUTION. default: false (for a reason)

Examples:

aws_s3_bucket 'some-unique-name' do
  aws_access_key aws['aws_access_key_id']
  aws_secret_access_key aws['aws_secret_access_key']
  versioning true
  region 'us-west-1'
  action :create
end
aws_s3_bucket 'another-unique-name' do
  aws_access_key aws['aws_access_key_id']
  aws_secret_access_key aws['aws_secret_access_key']
  region 'us-west-1'
  action :delete
end

aws_secondary_ip

The secondary_ip resource provider allows one to assign/un-assign multiple private secondary IPs on an instance within a 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 as determined by Ohai will be used.

Examples:

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
