配置遗漏点 #

• 标签不匹配：流水线任务要求使用标签jenkins-eks-pod，但你配置的Pod模板标签是jenkins-non-prod-eks-global-slave，两者完全不一致，导致Jenkins找不到符合要求的代理节点。
• JNLP容器配置错误：日志显示JNLP容器退出码为0，但Jenkins判定为异常终止。你清空了JNLP容器的command和args，默认情况下这个容器需要接收Jenkins主节点的连接参数才能保持运行，空命令会让容器启动后直接退出。
• 缺少必要的连接参数：虽然设置了JENKINS_URL环境变量，但未配置JNLP容器的默认启动参数，导致代理无法与Jenkins主节点建立持久连接，容器启动后立即终止。
