Resource Annotations

This page presents the various resource annotations that Istio supports to control its behavior.

Annotation Name	Feature Status	Resource Types	Description
`galley.istio.io/analyze-suppress`	Alpha	[Any]	A comma separated list of configuration analysis message codes to suppress when Istio analyzers are run. For example, to suppress reporting of IST0103 (PodMissingProxy) and IST0108 (UnknownAnnotation) on a resource, apply the annotation ‘galley.istio.io/analyze-suppress=IST0108,IST0103’. If the value is ‘‘, then all configuration analysis messages are suppressed.
