Expand description

The two calls outside the MicroVMs API that ensure_image makes: the caller’s account, for the image ARN, and the artifact upload (#221, IMAGE-8).

BuildServices is the port. Sandbox::with_build_services takes one, a test records the calls and answers them, and production gets SignedBuildServices (in microvms-edges, re-exported as microvms_core::control::SignedBuildServices) through the plane’s adapters on the first ensure_image. The account comes from STS because GetMicrovmImage takes an ARN and the service rejects a bare name; GetCallerIdentity answers the account for any identity and needs no permission to make.
