带有嵌入式码头服务器的 Jersey 应用程序；日志不显示在 kubernetes

如何解决带有嵌入式码头服务器的 Jersey 应用程序；日志不显示在 kubernetes

我正在开发一个在嵌入式 Jetty 服务器上运行的 Jersey 应用程序：

AuthServiceApplication.kt

@JvmStatic
fun main(args: Array<String>) {
    try {
        val application = AuthServiceApplication()
        application.run()
    } catch (e: Exception) {
        LOGGER.error("Application execution failed",e)
    }
}

fun run() {
    val uri = UriBuilder
            .fromUri(parameters.serverHost)
            .port(parameters.serverPort)
            .build()

    val server = JettyHttpContainerFactory.createServer(uri,this)
    try {
        LOGGER.info("Started listening on {}:{}",uri.host,uri.port)
        server.join()
    } finally {
        server.destroy()
    }
}

我在 resources/logback.xml

中按如下方式配置了日志记录

<configuration>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>

    <root level="info">
        <appender-ref ref="STDOUT" />
    </root>
</configuration>

我使用的是 1.2.3 版的 logback：

// Logging
implementation("ch.qos.logback:logback-classic:1.2.3")
implementation("ch.qos.logback:logback-core:1.2.3")
implementation("org.slf4j:slf4j-log4j12:1.7.30")

我已经通过以下配置设法让这个应用程序在 Kubernetes 集群中运行：

apiVersion: apps/v1
kind: Deployment
metadata:
  namespace: sm
  name: auth-service
spec:
  selector:
    matchLabels:
      app: auth-service
  template:
    metadata:
      labels:
        app: auth-service
    spec:
      containers:
        - name: auth-service
          image: <URL>
          ports:
            - containerPort: 8082
---
apiVersion: v1
kind: Service
metadata:
  namespace: sm
  name: auth-service
spec:
  selector:
    app: auth-service
  ports:
    - port: 80
      targetPort: 8082
  type: ClusterIP

问题是当我尝试运行应用程序时，它失败了，我看到的唯一日志是：

Mar 25,2021 7:58:30 PM java.util.prefs.FileSystemPreferences$1 run
INFO: Created user preferences directory.
|  Welcome to JShell -- Version 13.0.2
|  For an introduction type: /help intro

jshell> %  

描述 pod 也没有提供太多帮助：

Events:

  ----     ------     ----               ----               -------

我想弄清楚为什么日志没有显示出来。它们在本地和 docker 容器中工作正常，但它们不会出现在 Kuberntes 集群中。我真的很感激帮助解决这个问题。
