Jenkins JLNP 代理没有响应

Question

我正在尝试使用 jenkins 和 kubernetesplugin。我使用 kubeadm 在 AWS 中部署了一个 kubernetes 集群，并在 EC2 VM 上安装了 jenkins。

我正在尝试使用 jenkins 中的管道在 kubernetes 集群中启动 Pod 的部署。

但是我总是让代理超时：

我的 pod 正在运行，但从属 pod 没有响应，并且消息指出

JNLP agent port is disabled and agents cannot connect this way

这是我目前的设置

podTemplate(cloud: 'kubernetes', label: 'mypod',containers: [
    containerTemplate(name: 'golang', image: 'golang:1.8.0', ttyEnabled: true, command: 'cat')
  ]) {

    node('mypod') {

        stage('Get a Golang project') {
            git url: 'https://github.com/hashicorp/terraform.git'
            container('golang') {
                stage('Build a Go project') {
                    sh 'echo hello world'
                }
            }
        }

    }
}

slave 通过 JNLP 端口（传入代理的 TCP 端口）上的 JNLP 连接回 Jenkins。如果您将转到管理 > 配置全局安全性；你会看到的；选择固定端口并指定一个值，比如 50000。
