Jenkins 管道 - 錯誤“由於早期失敗而跳過階段”

Question

我正在 Google Kubernetes Engine 上使用 Jenkins 構建 CD 管道，但在第一次構建時遇到了問題。 如下面的輸出所示，流水線階段被跳過“由於早期的失敗（s）”，我無法識別。

我對詹金斯很陌生，所以希望得到任何幫助。 我還在下面粘貼了 Jenkinsfile。

日志底部清楚地顯示以下消息：

ERROR: Node is not a Kubernetes node:

管道無法啟動 kubernetes 代理，因為主節點（根據日志：“在 /var/jenkins_home/workspace/sample-app_canary 中的 Jenkins 上運行”）不在管理雲部分中設置的 kubernetes 集群中在詹金斯。
