Jenkins Slave 打印消息 Cannot contact slave-host: java.io.IOException: Remote call on Channel to /10.0.2.2 failed

Question

我有 Jenkins 2 Master 和 Jenkins 2 Slave。当我开始构建时，它是成功的，但是当我检查构建控制台时，我可以看到多行消息如下：

Cannot contact slave-host: java.io.IOException: Remote call on Channel to /10.0.2.2 failed

配置如下：

詹金斯大师 - Docker

java version "1.8.0_92"
Java(TM) SE Runtime Environment (build 1.8.0_92-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.92-b14, mixed mode)

Jenkins 奴隶 - 运行 Oracle Linux

java version "1.8.0_112"
Java(TM) SE Runtime Environment (build 1.8.0_112-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.112-b15, mixed mode)

执行 shell 命令时会抛出错误消息。

Jenkins 文件的一部分

stage("deploy") {
  node("slave-host") {
    step([$class: 'WsCleanup'])
      app_home = "/apps/tomcat"
      tomcat_home = "tomcat-server"
      id = 'package'
      sh "${app_home}/${tomcat_home}/bin/shutdown.sh &"
      unstash id
      sh "unzip *.zip"
      sh "cp *.war ${app_home}/wars"
  }
}

我是不是做错了什么？

Answer 1

this Jenkins ticket reported that they were able to get rid of the error by downgrading the "Pipeline: Nodes and Processes" plugin in Jenkins to 2.8 - available from here 中的一个用户。通过这样做，我也能够摆脱这个问题。不幸的是，我安装的许多其他插件都依赖于 2.10 版。我不热衷于对所有这些进行后调，所以我想我将不得不忍受这个烦恼，直到插件维护者提供正式修复为止。希望那会很快。
