AWS Outpost ID retrieval

Hi,

From Outposts FAQ: https://aws.amazon.com/outposts/rack/faqs/

Q: How does AWS maintain AWS Outposts rack infrastructure?

When your Outpost is installed and is visible in the AWS Management Console, 
AWS will monitor it as part of the public Region and will automatically execute 
software upgrades and patches.

If there is a need to perform physical maintenance, AWS will reach out to schedule 
a time to visit your site. AWS may replace a given module as appropriate but will 
not perform any host or network switch servicing on customer premises.

So, you should it your rack in the region : https://us-west-2.console.aws.amazon.com/outposts/home?region=us-west-2#Home. (change with your own region)

About id of rack, etc. From same faq:

Q: What type of control plane information flows back to the parent AWS Region?
As an example, information about instance health, instance activity (launched, 
stopped), and the underlying hypervisor system may be sent back to the parent 
AWS Region. This information enables AWS to provide alerting on instance health 
and capacity, and apply patches and updates to the Outpost. Your team does not 
need to implement your own tooling to manage these elements, or to actively push 
security updates and patches for your Outpost. For S3 on Outposts, certain data 
management and telemetry data, such as bucket names and metrics, may be stored 
in the AWS Region for reporting and management. When disconnected, this information 
cannot be sent back to the parent Region.

Best,

Didier
