Kubernetes Gateway API¶
本示例演示如何使用 DSM 部署支持的 httpbin 服务，并通过 Gateway API 进行访问。
先决条件¶
默认情况下不会安装 Gateway API。如果 Gateway API CRD 不存在，请安装：
kubectl get crd gateways.gateway.networking.k8s.io &> /dev/null || \
{ kubectl kustomize "github.com/kubernetes-sigs/gateway-api/config/crd?ref=v1.4.0" | kubectl apply -f -; }
创建服务¶
kubectl create -f https://raw.githubusercontent.com/apache/dubbo-kubernetes/master/samples/httpbin/httpbin.yaml
创建网关¶
kubectl create namespace dubbo-ingress
kubectl apply -f - <<EOF
apiVersion: gateway.networking.k8s.io/v1
kind: Gateway
metadata:

namespace: dubbo-ingress

测试服务¶
NODE_IP=$(kubectl get nodes -o jsonpath='{.items[0].status.addresses[?(@.type=="InternalIP")].address}')
SVC_PORT=$(kubectl get svc gateway-dubbo -n dubbo-ingress -o jsonpath='{.spec.ports[?(@.port==80)].nodePort}')
curl -s -I -HHost:httpbin.example.com "http://$NODE_IP:$SVC_PORT/get"
