jenkins kubernetes 插件在循环中运行 Pod，并且永远不会构建作业

Question

我正在使用 jenkins kubernetes 插件。配置它并测试如下示例管道代码:

podTemplate(containers: [
        containerTemplate(name: 'ssh-client', image: 'kroniak/ssh-client:3.6', ttyEnabled: true, command: 'cat')
]) {
    node(POD_LABEL) {
        stage('container log') {
            container('ssh-client') {
                sshagent (credentials: ['ContainerExecDecoratorPipelineTest-sshagent']) {
                    sh 'env'
                    sh 'ssh-add -L'
                    sh 'ssh -vT -o "StrictHostKeyChecking=no" git@github.com'
                }
            }
        }
    }
}

在构建过程中，我可以检查我的 kubernetes 集群并注意到 pod 正在创建但也在几秒钟后终止。它不断地无限发生。我什至检查了所有其他示例管道。 Jenkins 中的控制台输出显示:

Answer 1

kubectl logs <jenkins-pod> --namespace=<jenkins-namespace>是开始调试问题的一个很好的起点。
当您在 Manage Jenkins -> Configure System -> Cloud -> Kubernetes Cloud Details 下定义您的 Kubernetes 集群时, Jenkins URL 是否与 kubectl describe service jenkins 中的端点地址匹配?
端点地址必须与 Kubernetes 云详细信息中的 Jenkins URL 匹配

kubectl describe service jenkins -n jenkins | grep Endpoint
