1466686 - AWS provisioner worker status page lists inaccurate instance types

Status: RESOLVED DUPLICATE of bug 1453649

(Taskcluster :: UI, enhancement)

Description

[Gregory Szorc [:gps]]

The "Status" tab at e.g. https://tools.taskcluster.net/aws-provisioner/gecko-3-b-linux/ can list inaccurate EC2 instance types after you've updated a worker definition. As a concrete example, I've added c5d instance types to worker definitions, seen c5d instances advertised in the status tab, and opened the AWS web console only to not find a single c5d instance type instance!

Poking at the JSON API responses, I /think/ we may have code assuming that integer offsets align between the order instance types are defined in the worker definition and what is returned by an API. e.g. if you insert a new instance type - say c5d.4xlarge - as the first type in the worker definition, workers associated with offset 0 are now listed as c5d.4xlarge instance types in the "Status" tab.

This is a bit annoying when changing worker type definitions because you can't tell what EC2 instance types are actually provisioned. I have to resort to using the AWS web console to obtain this information.

You'll note that *all* of the numbers in the status page are zero.
