<!-- If you need to report a security issue please visit https://github.com/apache/dubbo/security/policy --> - [ ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate. ### Environment * Dubbo version: 3.0.6 * Operating System version: windows10 * Java version: 1.8 ### Steps to reproduce this issue 1. 配置dubbo参数，启动qos ``` dubbo: application: qos-port: 22222 qos-enable: true qos-accept-foreign-ip: true ``` 2. k8s集群配置readiness探针 ``` livenessProbe: failureThreshold: 20 httpGet: path: /live port: 22222 scheme: HTTP periodSeconds: 5 successThreshold: 1 timeoutSeconds: 1 readinessProbe: failureThreshold: 20 httpGet: path: /ready port: 22222 scheme: HTTP periodSeconds: 5 successThreshold: 1 timeoutSeconds: 1 startupProbe: failureThreshold: 20 httpGet: path: /startup port: 22222 scheme: HTTP initialDelaySeconds: 30 periodSeconds: 5 successThreshold: 1 timeoutSeconds: 1 ``` 3.容器中，使用命令行测试readiness探针返回值，永远为false ``` curl http://127.0.0.1:22222/live false ``` 5.通过跟踪代码，发现DeployerReadinessProbe的frameworkModel.getAllApplicationModels()中，存在一个modelName为"DUBBO_INTERNAL_APPLICATION"的项目，该项目的启动状态恒为false。 ``` package org.apache.dubbo.qos.probe.impl; import org.apache.dubbo.common.extension.Activate; import org.apache.dubbo.qos.probe.ReadinessProbe; import org.apache.dubbo.rpc.model.ApplicationModel; import org.apache.dubbo.rpc.model.FrameworkModel; import org.apache.dubbo.rpc.model.ModuleModel; import java.util.List; @Activate public class DeployerReadinessProbe implements ReadinessProbe { private FrameworkModel frameworkModel; public DeployerReadinessProbe(FrameworkModel frameworkModel) { this.frameworkModel = frameworkModel; } @Override public boolean check() { if (this.frameworkModel == null) { this.frameworkModel = FrameworkModel.defaultModel(); } List<ApplicationModel> applicationModels = frameworkModel.getAllApplicationModels(); for (ApplicationModel applicationModel : applicationModels) { for (ModuleModel moduleModel : applicationModel.getModuleModels()) { // bugfix 不判断 DUBBO_INTERNAL_APPLICATION 的 isStarted 状态 if ("DUBBO_INTERNAL_APPLICATION".equals(applicationModel.getModelName())) { continue; } if (!moduleModel.getDeployer().isStarted()) { return false; } } } return true; } } ``` 目前，项目中是通过跳过该项目状态检测的方法跳过此bug，现求助社区，寻求权威的解决方法： -- This is an automated message from the Apache Git Service.
