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:


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:

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": [
      "Sid": "Stmt1381536011000",
      "Resource": [
      "Effect": "Allow"

For resource tags:

  "Version": "2012-10-17",
  "Statement": [
      "Action": [
      "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 =
    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

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'

aws_ebs_volume 'db_ebs_volume' do
  size 50
  device '/dev/sdi'
  action [:create, :attach]

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

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

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


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.

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.


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

aws Cookbook CHANGELOG

This file is used to list changes made in each version of the aws cookbook.

7.0.0 (2017-06-15)

  • The route53_record resource from the route53 resource has been moved into this cookbook. The resource is now named aws_route53_record, but can be referenced by the old name: route53_record. The resource now accepts all authentication methods supported by this cookbook and a new zone_name property can be used in place of the zone_id property so you now only need to know the name of the zone the record is placed into.
  • Added a new aws_route53_zone resource for adding zones to Route53
  • Added new aws_s3_bucket resource. This is a very simple resource at the moment, but it lays the groundwork for a more complex resource for adding buckets with ACLs and other features
  • Converted all resources except for dynamodb_table to be custom resources. Logging and converging of resources has been updated and code has been cleaned up
  • Simplified the cookbook libraries by collapsing most of the libraries into the individual resources. For the most part these just added unnecessary complexity to the cookbook
  • Reworked how aws region information is determined and how the connection to AWS is initialized to work with some the new resources and the existing route53 resources
  • Moved the libraries from the Opscode::Aws namespace to the AwsCookbook namespace.
  • Large scale readme cleanup. There were multiple resources missing and some resources documented in 2 places. The documentation for resources is now ordered alphabetically and contains all actions and properties.
  • Updated elastic_ip resource to reload ohai after changes so ohai data reflects the current node state
  • Remove storage of IP information on the node when using the elastic_ip resource. This is a bad practice in general as node data can be changed or deleted by users or chef itself. This is potentially a breaking change for users that relied on this behavior.
  • Updated resource_tag to properly support why-run mode

6.1.1 (2017-06-05)

  • Resolve frozen string warning on Chef 13 in the s3_file rsource
  • Resolve useless assignment cookstyle warning in the EC2 library
  • Make the ELB deletion messaging consistent with the create messaging

6.1.0 (2017-05-01)

  • Converted aws_cloudwath and aws_elb to custom resources with code cleanup
  • Add create/delete actions to the aws_elb resource. This resource is currently not able to update the state of the ELB and does not setup health checks. It's mostly used to allow us to test the existing attach/detach actions, but it will be expanded in the future to allow for full ELB management
  • Cleanup of the EC2 helper and removal of a few unnecessary helpers

6.0.0 (2017-04-27)

  • Resolve deprecation warning in the chefspecs
  • Remove the EBS Raid resource, which did not work on modern EC2 instance types and only worked on select Linux systems. We highly recommend users utilize provisioned IOPS on EBS volumes as they offer far greater reliability. If that's not an option you may want to pin to the 5.X release of this cookbook.
  • Remove the ec2_hints recipe as newer Chef releases auto detect EC2 and don't require hints to be applied
  • Use Chef's gem install in the metadata to handle gem installation. This increases the minimum required Chef release to 12.9
  • Convert instance_monitoring to a custom resource with improved logging and converge notification
  • Consider pending to be enabled as well within instance_monitoring to avoid enabling again

5.0.1 (2017-04-18)

  • Fix for Issue #283 (error on aws_resource_tag): Updated deprecated Chef::Resource call with valid Chef::ResourceResolver drop-in

5.0.0 (2017-04-11)

  • Calculate the presigned url after the md5 check as it may timeout when the existing file is very large
  • Update testing for Chef 13 and use local delivery
  • Update apache2 license string
  • Require the latest ohai cookbook which fixes Chef 13 compatibility. With this change this cookbook now requires Chef 12.6 or later

4.2.2 (2017-02-24)

  • Let the API decide what the default volume type is for EBS volumes. This doesn't actually change anything at the moment, but keeps us up to date with the defaults of the aws-sdk

4.2.1 (2017-02-24)

  • Tweaks to the readme for clarity
  • Remove Ubuntu 12.04 and openSUSE 13.2 from Test Kitchen matrix as these are both on the way to EOL
  • Remove the sensitive, retries, and retry_delay from the s3_file resource for Chef 13 compatibility since chef itself defines these

4.2.0 (2017-01-21)

  • README: Add ec2:ModifyInstanceAttribute to sample IAM policy (fixes #241)
  • Added a new resource for managing CloudWatch alarms

4.1.3 (2016-11-01)

  • Dont declare region twice in S3_file

  • Use alias_method to cleanup backwards compatibility in s3_file

4.1.0 (2016-09-19)

  • Pass through retry_delay to remote_file
  • Require ohai 4.0+ cookbook and use new compile_time method for ohai_hint resource
  • Remove Chef 11 compatibility code in the aws-sdk gem install

4.0.0 (2016-09-15)

  • Testing updates
  • Require Chef 12.1 or later
  • Use node.normal instead of node.set to avoid deprecation notices
  • Warn in the logs if the default recipe is included
  • Remove the ohai reload on every run in the hint recipe
  • Remove chef 11 compat in the metadata

3.4.1 (2016-08-09)

  • Modified find_snapshot_id method to make it work as intended
  • Testing framework updates

v3.4.0 (2016-06-30)

  • Added retries property to s3_file
  • Switched docker based test kitchen testing to kitchen-dokken
  • Added chef_version support metadata

v3.3.3 (2016-05-10)

  • Add support for new ebs volume types: sc1 st1

v3.3.2 (2016-04-13)

  • Resolved no method error when using the elb resource
  • Fixed a bug in the md5 check in the s3_file resource

v3.3.1 (2016-03-25)

  • Only install the aws-sdk gem at compile_time if chef-client supports that

v3.3.0 (2016-03-25)

  • The AWS gem is now automatically installed as needed by the providers
  • Added ChefSpec matchers for: cloudformation_stack, dynamodb_table, elastic_lb, iam_*, kinetic_stream, scondary_ip.

v3.2.0 (2016-03-23)

  • Add the :delete action to the ebs_volume provider

v3.1.0 (2016-03-22)

  • Added the sensitive attribute to the s3_file provider
  • s3_file provider now compares md5sums of local files against those in S3 to determine if the file should be downloaded during the chef-client run
  • s3_file provider now properly handles region by defaulting to us-east-1 unless a region is provided in the resource
  • An inspec test suite has been added for the s3_file provider
  • s3 connection objects are no longer stored in a per-region hash as this is longer necessary with the changes to how connection objects are stored
  • The region method in the S3 module has been removed as it wasn't being used after region handling refactoring in the 3.0 release

v3.0.0 (2016-03-20)

Breaking changes:

  • Removed the ability to use databags for credentials with the ebs_raid provider. You must now pass the credentials in via the resource, @tas50
  • #218 Remove support for Chef < 11.6.0, @tas50
  • Switched to Ohai to gather information on the AWS instance instead of direct AWS metadata calls. This also removes the node['region'] attribute, which is no longer necessary. If you would like to mock the region for some reason in local testing set node['ec2']['placement_availability_zone'] to the AZ, as this is used to determine the region, @tas50
  • aws-sdk gem is no longer loaded in default recipe
