How to run your app on Kubernetes through a Jenkins build/post build step - plugins

Question

I tried looking for a Jenkins plugin (like AWS codeDeploy) so that I could deploy my application to a Kubernetes cluster. So far, I have been successful at pushing it to a Docker registry and adding some command line build steps to deploy to Kubernetes.
Looking at the CloudBees announcement this seems possible
Installing the Kubernetes plugin gave me errors...I can attach a screenshot if that helps ...
Also it seems like this plugin allows you to run slaves in Docker containers not deploy your own app.
After looking at this video
, it seemed I could accomplish this
using the withKubernetes workflow stage...
However adding that line to my workflow script gives me the following error
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]

Answer 1

The Jenkins Kubernetes plugin is (so far) only to run slaves dynamically in a Kubernetes cluster
There's not a lot about deploying from Jenkins to Kubernetes, maybe this post Continuous Delivery Pipelines with Fabric8 and Jenkins on OpenShift helps
