Actions

Attribute Parameters

Usage Examples

# Provide all credential information to download file and store it to /tmp/testfile
cloudcli_aws_s3_file '/tmp/testfile' do
  aws_access_key_id 'YOUR_ACCESS_KEY_ID'
  aws_secret_access_key 'YOUR_SECRET_ACCESS_KEY'
  region 'us-west-2'
  bucket 'my-test-bucket'
  key 'my_large_file.gz'
  checksum '37f9405a23d1e53082dbe9ea0ef19ec8791c778a6ecd0b02a6c1af2cf9bd4847'
  timeout 1200
  owner 'testuser'
  group 'testgroup'
  mode '0644'
end

# Do not pass any credentials to provider because our instance is on EC2 and uses an IAM Profile
cloudcli_aws_s3_file '/tmp/testfile' do
  bucket 'my-test-bucket'
  key 'my_large_file.gz'
end

cloudcli_aws_credentials

This resource allows you to setup credential files for aws-cli. The resource is designed to only write out the credentials file once. Because of this, you can write multiple profiles for the same credentials file with multiple calls to this resource. Take a look at the examples section for an example of this behavior.

Usage Examples

# Standard configuration setting access key, secret key and region
cloudcli_aws_credentials '/etc/aws/credentials' do
  owner 'testuser'
  group 'testuser'
  mode 0600
  credential_params(
    aws_access_key_id: 'ASDASDASKD123',
    aws_secret_access_key: 'TESTPASS12345',
    region: 'us-west-2'
  )
end

cloudcli_aws_credentials '/etc/aws/credentials' do
  owner 'testuser'
  group 'testuser'
  profile 'primary'
  mode 0600
  credential_params(
    aws_access_key_id: 'ASDASDASKD123',
    aws_secret_access_key: 'TESTPASS12345',
    region: 'us-west-2'
  )
end

# Creating a cross-account role profile named secondary in the same credentials file
# as the `primary` profile defined above.
cloudcli_aws_credentials '/etc/aws/credentials' do
  owner 'root'
  group 'root'
  mode 0660
  profile 'secondary'
  credential_params(
    region: 'eu-west-2',
    role_arn: 'arn:aws:iam::123456789012:role/testingchef'
  )
end

# Configuring S3 threading parameters
s3_config = <<EOF

  max_queue_size=10000
  multipart_threshold=64MB
  multipart_chunksize=16MB
EOF

cloudcli_aws_credentials '/home/testuser/.aws/credentials' do
  owner 'testuser'
  group 'testuser'
  mode 0600

    aws_access_key_id: 'TEST123',
    aws_secret_access_key: 'SECRETKEY!',
    s3: s3_config
  )
end

Testing

In order to run the integration tests for this cookbook, you must have a valid AWS account and go through a few setup steps. Please note, you may incur AWS fees when executing the kitchen integration tests.

Local Configuration

The testing suites are setup to use environment variables to pass in end user specific information.

Variables used by .kitchen.yml

These variables are used to setup the test_get and profile_test_get (kitchen-ec2 only) suites. Kitchen will setup proper node attributes based on these variables. See the .kitchen.yml file for information on which variables are set.

export TEST_AWS_ACCESS_KEY_ID=
export TEST_AWS_SECRET_ACCESS_KEY=
export TEST_AWS_REGION=
export TEST_BUCKET=
export TEST_KEY=
export TEST_CHECKSUM=

Variables used by .kitchen.ec2.yml

The .kitchen.ec2.yml file is used to test within EC2. In order to use it, you must configure proper AWS security credentials as well as a few other settings. Take a look at .kitchen.ec2.yml to see which specific kitchen-ec2 variables are set from these environment variables.

export AWS_ACCESS_KEY_ID=
export AWS_SECRET_ACCESS_KEY=
export AWS_KEYPAIR_NAME=
export AWS_REGION=
export AWS_SUBNET_ID=
export AWS_AVAILABILITY_ZONE=
export EC2_SSH_KEY_PATH=
export AWS_IAM_PROFILE=
export AWS_UBUNTU_1404_AMI=
export AWS_AMAZON_AMI=

AWS Configuration

test_get suite dependencies

The following items need to be setup properly in order to use the test_get suite.

• AWS S3 Bucket containing a test file
• AWS IAM Account with at least GetObject access to the bucket setup in the previous step
• AWS IAM Account API keys for the account setup in the previous step

profile_test_get suite dependencies

The following items need to be setup properly in order to use the profile_test_get suite.

• AWS S3 Bucket containing a test file
• AWS IAM Role/Profile with at least GetObject access to the bucket setup in the previous step
• AWS IAM Account API Keys for an account with enough access to run an EC2 instance

Executing the integration tests

The test_get suite will download the file by providing the credentials configured via the environment. Those files will then be verified against the checksum you set via TEST_CHECKSUM. If the checksum does not match the downloaded file, the tests will fail.

Note: kitchen-ec2 profile support is waiting for a release. If you would like to test with IAM profiles, you will need to build the kitchen-ec2 gem from source.

The profile_test_get suite is only available when using the kitchen-ec2 driver. The .kitchen.cloud.yml file is configured to use the kitchen-ec2 driver. To enable this file, set the KITCHEN_LOCAL_YAML environment variable to the path for the .kitchen.cloud.yml file.
