An Istio annotation is applied to the wrong kind of resource.
IST0108: UnknownAnnotation
An Istio annotation is not recognized for any kind of resource
IST0109: ConflictingMeshGatewayVirtualServiceHosts
Conflicting hosts on VirtualServices associated with mesh gateway
IST0110: ConflictingSidecarWorkloadSelectors
A Sidecar resource selects the same workloads as another Sidecar resource
IST0111: MultipleSidecarsWithoutWorkloadSelectors

A VirtualService routes to a service with more than one port exposed, but does not specify which to use.
IST0113: MTLSPolicyConflict
A DestinationRule and Policy are in conflict with regards to mTLS.
IST0116: DeploymentAssociatedToMultipleServices
The resulting pods of a service mesh deployment can't be associated with multiple services using the same port but different protocols.
IST0117: DeploymentRequiresServiceAssociated
The resulting pods of a service mesh deployment must be associated with at least one service.
IST0118: PortNameIsNotUnderNamingConvention
Port name is not under naming convention. Protocol detection is applied to the port.

A service registry in Mesh Networks is unknown
IST0127: NoMatchingWorkloadsFound
There aren't workloads matching the resource labels
IST0128: NoServerCertificateVerificationDestinationLevel
No caCertificates are set in DestinationRule, this results in no verification of presented server certificate.
IST0129: NoServerCertificateVerificationPortLevel
No caCertificates are set in DestinationRule, this results in no verification of presented server certificate for traffic to a given port.
IST0130: VirtualServiceUnreachableRule

Virtual service using JWT claim based routing without request authentication.
IST0150: ExternalNameServiceTypeInvalidPortName
Proxy may prevent tcp named ports and unmatched traffic for ports serving TCP protocol from being forwarded correctly for ExternalName services.
IST0151: EnvoyFilterUsesRelativeOperation
This EnvoyFilter does not have a priority and has a relative patch operation set which can cause the EnvoyFilter not to be applied. Using the INSERT_FIRST or ADD option or setting the priority may help in ensuring the EnvoyFilter is applied correctly.
IST0152: EnvoyFilterUsesReplaceOperationIncorrectly
The REPLACE operation is only valid for HTTP_FILTER and NETWORK_FILTER.
IST0153: EnvoyFilterUsesAddOperationIncorrectly
The ADD operation will be ignored when applyTo is set to ROUTE_CONFIGURATION, or HTTP_ROUTE.
IST0154: EnvoyFilterUsesRemoveOperationIncorrectly
The REMOVE operation will be ignored when applyTo is set to ROUTE_CONFIGURATION, or HTTP_ROUTE.
IST0155: EnvoyFilterUsesRelativeOperationWithProxyVersion
This EnvoyFilter does not have a priority and has a relative patch operation (NSTERT_BEFORE/AFTER, REPLACE, MERGE, DELETE) and proxyVersion set which can cause the EnvoyFilter not to be applied during an upgrade. Using the INSERT_FIRST or ADD option or setting the priority may help in ensuring the EnvoyFilter is applied correctly.
