ServiceEntryAddressesRequired
This message occurs when a ServiceEntry with the protocol
field not set, or set to TCP
, doesn’t have addresses
defined.
Example
You will receive this message:
Warning [IST0134] (ServiceEntry service-entry.default serviceentry.yaml:13) ServiceEntry addresses are required for this protocol.
when your cluster has the following ServiceEntry with unset protocol and missing addresses:
apiVersion: networking.istio.io/v1alpha3
kind: ServiceEntry
metadata:
name: service-entry
namespace: default
spec:
hosts:
- 'istio.io'
exportTo:
- "."
ports:
- number: 443
name: https
location: MESH_EXTERNAL
resolution: DNS
another example of this analyzer is when you have a ServiceEntry with TCP protocol and missing addresses:
apiVersion: networking.istio.io/v1alpha3
kind: ServiceEntry
metadata:
name: service-entry
namespace: default
spec:
hosts:
- 'istio.io'
exportTo:
- "."
ports:
- number: 443
name: https
protocol: TCP
location: MESH_EXTERNAL
resolution: DNS
How to resolve
Make sure to set addresses
in your ServiceEntry when protocol
is not set, or set to TCP. If addresses
is not set, all traffic on the port defined in the ServiceEntry is matched, regardless of the host.
