我对这两个感到困惑。两者都是在启用了 Istio 插件的 GKE 集群上配置的,两者都是 LoadBalancer 类型,但它们位于不同的命名空间中。他们的用例可能是什么?
gke-system命名空间
vagrant@ubuntu-xenial:~/cloud_donws/iac$ kubectl get svc -n gke-system
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
cluster-local-gateway ClusterIP 10.53.0.76 <none> 15020/TCP,80/TCP,443/TCP 11h
istio-ingress LoadBalancer 10.53.23.203 35.x.113.x 15020:31917/TCP,80:30102/TCP,443:31494/TCP 11h
istio-pilot ClusterIP 10.53.20.61 <none> 15010/TCP,15011/TCP,8080/TCP,15014/TCP 11h
istio 系统命名空间
vagrant@ubuntu-xenial:~/cloud_donws/iac$ kubectl get svc -n istio-system
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
istio-citadel ClusterIP 10.53.19.175 <none> 8060/TCP,15014/TCP 11h
istio-galley ClusterIP 10.53.26.27 <none> 443/TCP,15014/TCP,9901/TCP 11h
istio-ingressgateway LoadBalancer 10.53.27.245 x.197.x.218 15020:31856/TCP,80:31966/TCP,443:30142/TCP,31400:30876/TCP,15029:30354/TCP,15030:32017/TCP,15031:32425/TCP,15032:32647/TCP,15443:31390/TCP 11h
istio-pilot ClusterIP 10.53.11.103 <none> 15010/TCP,15011/TCP,8080/TCP,15014/TCP 11h
istio-policy ClusterIP 10.53.0.53 <none> 9091/TCP,15004/TCP,15014/TCP 11h
istio-sidecar-injector ClusterIP 10.53.4.58 <none> 443/TCP 11h
istio-telemetry ClusterIP 10.53.3.170 <none> 9091/TCP,15004/TCP,15014/TCP,42422/TCP 11h
promsd ClusterIP 10.53.15.102 <none> 9090/TCP 11h
就像谷歌的这个例子:
它指向istio-ingress.gke-system.svc.cluster.local而不是istio-ingressgateway.istio-system.svc.cluster.local
