YUM timeout

Could not retrieve mirrorlist http://repo.us-west-2.amazonaws.com/latest/main/mirror.list error was
    amazon-ebs: 12: Timeout on http://repo.us-west-2.amazonaws.com/latest/main/mirror.list: (28, 'Connection timed out after 10001 milliseconds')

First get the Interface mac address, then use that to run the full command

INTERFACE=$(curl --silent http://169.254.169.254/latest/meta-data/network/interfaces/macs/)
SUBNET_ID=$(curl --silent http://169.254.169.254/latest/meta-data/network/interfaces/macs/${INTERFACE}/subnet-id)
VPC_ID=$(curl --silent http://169.254.169.254/latest/meta-data/network/interfaces/macs/${INTERFACE}/vpc-id)

echo SUBNET_ID

	# This code deletes buckets on AWS S3.
	# It is designed to be run on a local machine with credentials for an AWS account that has the
	# necessary permissions to delete buckets.
	# It will delete the contents of the buckets before deleting the bucket itself.
	# It will not attempt to delete a bucket that does not exist.

	# BUCKETS is a list of bucket names that should be deleted. If a bucket in the list does not
	# exist, it will be skipped.

	Usage example:

	Send memory usage metrics to Amazon CloudWatch

	This is intended to run on an Amazon EC2 instance and requires an IAM
	role allowing to write CloudWatch metrics. Alternatively, you can create
	a boto credentials file and rely on it instead.

	Original idea based on https://github.com/colinbjohnson/aws-missing-tools
