aws_info

AwsInfo

A gem to provide an easy way to load the AWS information from a given AWS instance. Automatically detect server IP, Region, Availability Zone, etc. as well as instance tags.

Under the hood this gem uses the aws meta data lookup url for instance information: http://169.254.169.254/latest/dynamic/instance-identity/document

And it uses aws describe tags command on the aws server to get a list of tags: "aws ec2 describe-tags ..."
