Check if Azure Instance Metadata Service (IMDS) is Available

This function checks if the Azure Instance Metadata Service (IMDS) is available by attempting to make a request to the IMDS endpoint. The result is cached in an environment variable for future use, saving the need for repeated checks.

Usage

imds_available()

Details

You can also set the IMDS_AVAILABLE environment variable manually to "TRUE" or "FALSE" to override the automatic check, which can be useful for testing or in environments where the check may not work correctly.
