OpenSergoClient gRPC disconnection: DEADLINE_EXCEEDED #29

Open ruansheng8 opened 1 year ago

ruansheng8 commented 1 year ago

问题描述

部署opensergo-control-plane到K8S后 , 客户端连接成功，也成功加载了并生效了相关配置，超过Deadline限定时间(OpenSergoClient默认10S)后自动断开 Spring Boot 2.5.12，opensergo-java-sdk 0.1.0，Sentinel 2.0.0-alpha，opensergo-control-plane 基于main分支最新代码部署

问题验证

通过 sentinel-demo-opensergo-datasource 进行验证

启动客户端后连接正常（opensergo-control-plane可以看到客户端的连接的日志），且可以正确的获取到opensergo-control-plane中相关CRD配置，通过请求接口验证限流规则也正确的被加载，但是gRPC连接会自动断开，本地启动客户端或者在集群中使用域名opensergo-control-plane.opensergo-system.svc.cluster.local连接都有一样的问题。

2023-03-16 14:30:46.714 ERROR 22976 --- [ault-executor-2] openSergoLogger                          : Fatal error occurred on OpenSergo gRPC ClientObserver

io.grpc.StatusRuntimeException: DEADLINE_EXCEEDED: deadline exceeded after 9.937407200s. [closed=[], committed=[wait_for_ready, buffered_nanos=255123700, remote_addr=/192.168.4.161:10246]]

OpenSergoClient.java 中通过withDeadlineAfter来设置截止时间 , 通过手动将截止时间(withDeadlineAfter)设置为1分钟然后验证功能，期间动态修改相关CRD限流规则 , 功能一切正常(限流规则可以实时生效)，但是1分钟后客户端gRPC连接依然会被自动断开（具体见下面客户端日志）。

    public void start() throws Exception {
        this.requestAndResponseWriter = transportGrpcStub
            .withWaitForReady()
            // The deadline SHOULD be set when waitForReady is enabled
            .withDeadlineAfter(10, TimeUnit.SECONDS)
            .subscribeConfig(new OpenSergoSubscribeClientObserver(configCache, subscribeRegistry));
        // TODO: add state management for the client.
    }
