如何使用负载均衡器向外界公开 kubernetes 服务

Question

我想使用负载均衡器 IP 向外界公开我的 Prometheus 服务 这是我的清单文件

class Cd_MixedView(UpdateView):
    model = Track
    template_name = 'cd_mixed_view.html'
    form_class = TrackForm
    context_object_name = 'cd_edit'
    
    def get_context_data(self, **kwargs):
        context = super(Cd_MixedView,self).get_context_data(**kwargs)
        cur_track = self.object # no need to get the object again it is already present in `self.object`
        # form is already added to context by super method
        context['cd_info'] = Cd.objects.get(id=cur_track.cd_id.pk)
        return context
    # `post`, `form_valid` and `form_invalid` methods were same as super so no need to write yourself

这是我的服务仪表板

这个 34.66.144.24 是我的预留 IPv4 对于这里有一些 IP 的端点，只要我点击 apiVersion: v1 kind: Service metadata: annotations: kubectl.kubernetes.io/last-applied-configuration: | {"apiVersion":"v1","kind":"Service","metadata":{"annotations":{"prometheus.io/scrape":"true"},"labels":"name":"prometheus","namespace":"istio-system"},"spec":{"ports":[{"name":"http-prometheus","port":9090,"protocol":"TCP"}],"selector":{"app":"prometheus"}}} prometheus.io/scrape: "true" creationTimestamp: "2021-04-20T04:05:35Z" labels: app: prometheus install.operator.istio.io/owning-resource: installed-state install.operator.istio.io/owning-resource-namespace: istio-system release: istio managedFields: - apiVersion: v1 fieldsType: FieldsV1 fieldsV1: f:metadata: f:labels: .: {} f:app: {} f:install.operator.istio.io/owning-resource: {} f:install.operator.istio.io/owning-resource-namespace: {} f:spec: f:ports: .: {} k:{"port":9090,"protocol":"TCP"}: .: {} f:name: {} f:port: {} f:protocol: {} f:targetPort: {} manager: istioctl operation: Update time: "2021-04-20T04:05:35Z" - apiVersion: v1 fieldsType: FieldsV1 fieldsV1: f:spec: f:externalTrafficPolicy: {} f:loadBalancerIP: {} f:type: {} manager: Go-http-client operation: Update time: "2021-04-20T05:46:18Z" name: prometheus namespace: istio-system resourceVersion: "71791" spec: clusterIP: 172.26.232.117 externalTrafficPolicy: Cluster loadBalancerIP: 34.66.144.25 ports: - name: http-prometheus nodePort: 31057 port: 9090 protocol: TCP targetPort: 9090 selector: app: prometheus sessionAffinity: None type: LoadBalancer status: loadBalancer: {} ，它就会说“无法访问该站点
