Kubernetes Jenkins插件 - 奴隶总是离线

Question

我正在尝试使用Jenkins/Kubernetes插件与Jenkins协调docker奴隶.

我正在使用这个插件:https: //github.com/jenkinsci/kubernetes-plugin

我的问题是所有从站都处于脱机状态,因此作业无法执行:

我在使用minikube的本地盒子上以及由我们的ops组托管的K8群集上尝试了这个.我已经尝试了Jenkins 1.9和Jenkins 2.我总是得到相同的结果.屏幕截图来自Jenkins 1.642.4,K8 v1.2.0

这是我的配置...请注意,当我点击"测试连接"时,我获得了成功.另请注意,我不需要任何凭据(这是我可以看到的唯一区别与记录的示例).

Jenkins日志反复显示以下内容:

    Waiting for slave to connect (11/100): docker-6b55f1b7fafce

我跑的时候kubectl get events看到这个:

有任何想法吗？

更新:csanchez建议的更多日志信息

 ?  docker git:(master) ? kubectl get pods --namespace default -o wide
NAME                   READY     STATUS    RESTARTS   AGE       NODE

?  docker git:(master) ? kubectl log docker-6bafbac10b392

我将不得不看看这个端口50000用于什么？

Answer 1

您需要公开端口 8080 和 50000，如插件示例配置中所述https://github.com/jenkinsci/kubernetes-plugin/blob/master/src/main/kubernetes/jenkins.yml
