Please see TESTING_AGAINST_AWS.md for details on how to setup the needed AWS accounts to perform testing.

Follow these instructions carefully.

1. Create an AWS account. Make a note of the account email and root password in a secure secret storage system.
2. Create an IAM user named test-fixture-maker.

• Enable programmatic access (to generate an access key)
• Note the access key and secret key ID that are generated.

3. Create an IAM Group named test-fixture-maker-group.

• Direct-attach the policy AdministratorAccess
• Add user test-fixture-maker to the group

4. Set the required env variables.

• AWS Credentials

AWS_ACCESS_KEY_ID         - The AWS Access Key that is to be used (default: none)
AWS_SECRET_ACCESS_KEY     - The AWS Secret Access Key that is to be used (default: none)

• TF_VAR_ prevents credentials from being populated on terrafrom logs

TF_VAR_aws_ssh_key_id     - The value is the name of the AWS key pair you want to use (default: none) (hide from logs)
TF_VAR_aws_access_key     - The AWS Access Key that is to be used (default: none) (hide from logs)
TF_VAR_aws_secret_key     - The AWS Secret Access Key that is to be used (default: none) (hide from logs)

Build/Verify

Run Test kitchen

a. bundle exec kitchen list
b. bundle exec kitchen create cis-setup
c. bundle exec kitchen converge cis-setup
d. bundle exec kitchen verify cis-setup
e. bundle exec kitchen destroy cis-setup

Known Issues

1. AWS Simple Queue Service takes a few minutes to build, so please wait a few minutes before running kitchen verify.

2. Known Terrafrom bug that affects Managed policy attachment shows up on a second kitchen converge or kitchen destroy. https://github.com/hashicorp/terraform/issues/5979 . Please converge or destroy again to get past the error.
