Explanation: Because your instance metadata is available from your running instance, you do not need to use the Amazon EC2 console or the AWS CLI. This can be helpful when you're writing
scripts to run from your instance. For example, you can access the local IP address of your instance from instance metadata to manage a connection to an external application.

To view all categories of instance metadata from within a running instance, use the following URI:

http://169.254.169.254/latest/meta-data/
Note that you are not billed for HTTP requests used to retrieve instance metadata and user data.

You can use a tool such as cURL, or if your instance supports it, the GET command; for example:

$ curl http://169.254.169.254/latest/meta-data/
$ GET http://169.254.169.254/latest/meta-data/
You can also download the Instance Metadata Query tool, which allows you to query the instance metadata without having to type out the full URI or category names:

http://aws.amazon.com/code/1825

All metadata is returned as text (content type text/plain). A request for a specific metadata resource returns the appropriate value, or a 404 - Not Found HTTP error code if the
resource is not available.

A request for a general metadata resource (the URI ends with a /) returns a list of available resources, or a 404 - Not Found HTTP error code if there is no such resource. The list
items are on separate lines, terminated by line feeds (ASCII 10).
curl http://169.254.169.254/latest/meta-data/local-hostname
ip-10-251-50-12.ec2.internal
