配置Jenkins連線kubernetes模板

如果跑java 的流水線工程，顯示Jenkins從業務節點pending狀態，如果是排程出現cpu或者記憶體大小資源問題，可以到Jenkins "配置">"configure cloud" > "kubernetes" > "Template" > "java模板" 中修改resource的大小，使其可以分配

進入Jenkins配置->修改Configure Cloud模板

配置一個kubernetes節點

增加Pod Template配置

在最下面增加pod template配置，當前主要增加了預設的Jenkins-slave節點、Jenkins-slave-Java節點、Jenkins-slave-golang1.15節點、Jenkins-slave-python3.7節點、Jenkins-slave-nodejs12節點的模板。

分解顯示--> base Template

分解顯示--> Java Template

分解顯示--> golang1.15 Template

分解顯示--> nodejs12 Template

分解顯示--> Python 3.7 Template

以上就是Jenkins web 頁面連線kubernetes的配置，主要是連線Jenkins之後使其自動拉起Jenkins-slave元件。

附上釋出Java的Jenkinsfile檔案

Jenkinsfile檔案如下
