Chef uninitialized constant Chef::Recipe::AWS

Question

My cookbook is not compiling throwing the error uninitialized constant Chef::Recipe::AWS. The chef_gem aws-sdk installed fine, but still doesn't compile when AWS.config(access_key_id: 'key', secret_access_key: 'pass') is called.

chef_gem "aws-sdk"

AWS.config(access_key_id: key, secret_access_key: pass)

rds = AWS::RDS.new

Answer 1

According to the doc from aws-sdk-ruby here and to the code, the class name is Aws and not AWS .

But your main problem here is that you're not including the lib installed by the gem.

add require 'aws-sdk' before trying to call it's class.

To avoid being bitten by a name conflict with the Chef::Recipe namespace call the lib as a top level lib like ::Aws.config(...)

Edit from personnal research: AWS namespace is from the sdk v1, if you really wish to use this one and not the v2 you have to change your recipe to:

chef_gem "aws-sdk-v1"

require 'aws-sdk-v1'
AWS.config(access_key_id: key, secret_access_key: pass)

rds = AWS::RDS.new

Answer 2

You need to provide to aws-sdk gem your aws credentials. As you can read in the gem documentation:

Basic Configuration

You need to provide your AWS security credentials and choose a default region.

AWS.config(access_key_id: '...', secret_access_key: '...', region: 'us-west-2')

You can also specify these values via ENV:

export AWS_ACCESS_KEY_ID='...' export AWS_SECRET_ACCESS_KEY='...' export AWS_REGION='us-west-2'

Edit 'key' and 'pass' with your credentials, and add the aws region you want to use.
