dubbo - Jenkins部署 - 《kubernetes》

给jenkins配置maven环境

这里装完后发现2.190.3版本太老好多依赖插件报错
所以用2.204.1的底包又重新打了一版镜像
这里遇到一个小坑 apply后Jenkins的版本还是2.190.3 最后发现是node节点上的镜像没有自动更新这和deployment里面的pull镜像策略有关imagePullPolicy: IfNotPresent

这里的账户密码在spinnaker的deployment文件里面有用到

这个url是 Jenkins URL变量的值所以我填了内网的域名
但是进去之后报错
参考这个修改一下 https://blog.csdn.net/fxy0325/article/details/88131947
