1658785 - AWS API errors when provisioning comm-* Decision workers

Status: RESOLVED FIXED

(Release Engineering :: Firefox-CI Administration, defect)

Description

[Rob Lemley [:rjl]]

The error reported in Taskcluster is:
Error calling AWS API: The requested configuration is currently not supported. Please check the documentation for supported configurations.

This is a worker for comm-1/decision.
https://hg.mozilla.org/ci/ci-configuration/file/tip/worker-pools.yml#l348
Most likely one of the listed instance types isn't available in one of the listed regions

I'm thinking that it's this: https://hg.mozilla.org/ci/ci-configuration/file/tip/worker-pools.yml#l387

    - instanceType: c5ad.xlarge
      capacityPerInstance: 2
      worker-config:
        capacityManagement: {diskspaceThreshold: 30000000000}

c5ad is not listed at https://aws.amazon.com/ec2/instance-types/c5/. I've seen some references to c5ad elsewhere "coming soon". m5ad are listed in the docs.
I'll submit a patch to remove that type.

I'm not able to find this class listed in the current ec2 docs:

I haven't seen the errors since this deployed.
