模块Service

ModuleService 简介

K8S 通过 Service ，将运行在一个或一组 Pod 上的网络应用程序公开为网络服务。 模块也支持 Module 相关的 Service ，在模块发布时自动创建一个 service 来服务模块，将安装在一个或一组 Pod 的模块公开为网络服务。 具体见：OperationStrategy.ServiceStrategy

字段解释

OperationStrategy.ServiceStrategy 字段解释如下：

字段解释取值范围
EnableModuleService开启模块servicetrue or false
Port公开的端口1 到 65535
TargetPortpod上要访问的端口1 到 65535

示例

kubectl apply -f sofa-serverless/module-controller/config/samples/module-deployment_v1alpha1_moduledeployment_provider.yaml --namespace yournamespace
