问题：

Jenkins奴隶未能写信给jarCache

邓才
2023-03-14

背景信息：我有一个Kubernetes集群，有3个linux节点和1个windows节点。从詹金斯大师到特工的一切都在一个由库伯奈斯控制的容器或吊舱里。

我试图将Windows代理（在容器中）连接到Linux主服务器（也在容器中），但在使用hudson.remoting.jnlp将从服务器连接到主服务器时遇到了问题。

以下是该命令的错误：

我尝试匹配master和slave的Java版本，使用最新的Remoting.jar文件并更改协议类型。任何帮助或想法都将被告知

我可以看到一些我建议改变的事情：

  1. 您的启动命令

java-cp c:\slave2.jar hudson.remoting.jnlp.main-headless-tunnel:50000-URL http://:8080-workdir c:\jenkins\agents windows-jnlp-c3c71

错误，java.nio.file.nosuchFileException:\etc\hostname

该文件应该存在于Linux服务器上，而不存在于Windows服务器上的该位置。所以，有些东西在错误的地方寻找东西。

我建议进行以下调整，将Windows从服务器连接到Linux主机：

Manage Jenkins -> Configure Global Security -> Agents

Manage Jenkins -> Manage Nodes -> [YOUR_NODE] -> Configure -> Launch Method

通过Java WebStart选择Launch agent，它将显示您应该使用的命令，您可以向其中添加隧道参数。
