如何通过Jenkins构建/post构建步骤在Kubernetes上运行应用程序

Question

我试着寻找一个Jenkins插件(比如AWS codeDeploy)，这样我就可以将我的应用程序部署到Kubernetes集群中。到目前为止，我已经成功地将它推到了Docker注册中心，并添加了一些命令行构建步骤来部署到Kubernetes。看CloudBees公告这似乎是可能的

安装Kubernetes插件给我带来了错误.如果有帮助的话，我可以附上截图.而且，这个插件似乎允许您在Docker容器中运行奴隶，而不是部署您自己的应用程序。

在查看了这段视频之后，我似乎可以使用withKubernetes工作流阶段来完成这一任务。

但是，将该行添加到工作流脚本会导致以下错误

java.lang.NoSuchMethodError: No such DSL method withKubernetes found among [archive, bat, build, catchError, checkout, dir, dockerFingerprintFrom, dockerFingerprintRun, echo, error, fileExists, git, input, load, mail, node, parallel, publishHTML, pwd, readFile, retry, sh, sleep, stage, stash, step, svn, timeout, tool, unarchive, unstash, waitUntil, withDockerContainer, withDockerRegistry, withDockerServer, withEnv, wrap, writeFile, ws]

到目前为止，Jenkins Kubernetes插件只能在Kubernetes集群中动态地运行奴隶。

从Jenkins到Kubernetes没有太多的部署，也许这篇文章基于Fabric8和Jenkins的OpenShift连续输送管道能帮上忙
