本程序說明如何在 Apigee 混合式安裝中新增其他 Cloud Service Mesh 閘道。
安裝其他 Cloud Service Mesh 閘道
在 Cloud Service Mesh overlay.yaml
檔案中,您可以按照以下類似的模式新增更多入口閘道。請注意,spec.components[].label
和 spec.components[].k8s.service.selector
元素可讓您將命名入口網關與特定虛擬主機建立關聯,如「將入口網關指定為虛擬主機」一文所述。
apiVersion: install.istio.io/v1alpha1 kind: IstioOperator spec: profile: asm-gcp # hub: gcr.io/gke-release/asm # {"$ref":"#/definitions/io.k8s.cli.setters.anthos.servicemesh.hub"} components: ingressGateways: - name: istio-ingressgateway-dairy enabled: true label: app: istio-ingressgateway ingress_name: dairy k8s: service: selector: app: istio-ingressgateway ingress_name: dairy type: LoadBalancer ports: - name: status-port port: 15021 - name: http2 port: 80 targetPort: 8080 - name: https port: 443 targetPort: 8443 hpaSpec: minReplicas: 1 maxReplicas: 10 - name: istio-ingressgateway-vegetables enabled: true label: app: istio-ingressgateway ingress_name: vegetables k8s: service: selector: app: istio-ingressgateway ingress_name: vegetables ports: - name: http2 port: 80 targetPort: 8080 - name: status-port port: 15020 - name: https port: 443 targetPort: 8443 hpaSpec: minReplicas: 1 maxReplicas: 10 resources: requests: cpu: 300m memory: 128Mi
請按照 Cloud Service Mesh 說明文件 (適用於您的平台) 套用變更。
將 Cloud Service Mesh/istio ingress 指定為虛擬主機
您可以在覆寫檔案中,將標示為 Cloud Service Mesh/istio 的入口網頁閘道指定為特定虛擬主機。這項設定會指定 Apigee 會套用虛擬主機設定的入口閘道。在以下範例中,系統會將導向虛擬主機 milk-vh
的流量經由標示為 dairy
的輸入端導向,而導向其他兩個虛擬主機的流量則會經由 vegetables
輸入端導向。如安裝其他 Apigee Ingress Gateway 閘道一文所述,Ingress 必須正確標示。
virtualhosts: - name: milk-vh sslCertPath: cert-milk.crt sslKeyPath: cert-milk.key selector: app: istio-ingressgateway ingress_name: dairy - name: carrots-vh sslCertPath: cert-carrots.crt sslKeyPath: cert-carrots.key selector: app: istio-ingressgateway ingress_name: vegetables - name: ginger-vh sslCertPath: cert-ginger.crt sslKeyPath: cert-ginger.key selector: app: apigee-ingressgateway ingress_name: vegetables
