I have a kubernetes cluster running with calico network plugin, some
services in this cluster still need to connect to services outside of this
cluster.
Suppose one of these outside service is running on multiple
nodes:192.168.10.35:9000, 192.168.10.36:9000, then I create one service
without selector and enpoints pointed to this outside service, these are
the manifests files:
apiVersion: v1
kind: Service
metadata:
name: no-selector-service
spec:
ports:
- protocol: TCP
port: 9000
targetPort: 9000
---
apiVersion: v1
kind: Endpoints
metadata:
name: no-selector-service
subsets:
- addresses:
- ip: 192.168.10.35
ports:
- port: 9000
- addresses:
- ip: 192.168.10.36
ports:
- port: 9000
I am wondering how to do health check on service no-selector-service sort
of like haproxy health check do, for example do not send traffic to
192.168.10.35:9000 if 192.168.10.35:9000 is not responding?
