Module: Ohai::Mixin::AlibabaMetadata

Defined in:
lib/ohai/mixin/alibaba_metadata.rb

Overview

This code parses the Alibaba Instance Metadata API to provide details of the running instance.

Note: As of 2021-02-07 there is only one API release so we’re not implementing logic like the ec2 or azure mixins where we have to find the latest supported release
