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

10/16/2015

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 http://blog.cloudbees.com/2015/07/orchestrating-deployments-with-jenkins.html

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 https://www.youtube.com/watch?v=PFCSSiT-UUQ , 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] at org.jenkinsci.plugins.workflow.cps.DSL.invokeMethod(DSL.java:107) at org.jenkinsci.plugins.workflow.cps.CpsScript.invokeMethod(CpsScript.java:112) at groovy.lang.GroovyObject$invokeMethod.call(Unknown Source) at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:42) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:108) at org.kohsuke.groovy.sandbox.impl.Checker$1.call(Checker.java:151) at org.kohsuke.groovy.sandbox.GroovyInterceptor.onMethodCall(GroovyInterceptor.java:21) at org.jenkinsci.plugins.scriptsecurity.sandbox.groovy.SandboxInterceptor.onMethodCall(SandboxInterceptor.java:75) at org.kohsuke.groovy.sandbox.impl.Checker$1.call(Checker.java:149) at org.kohsuke.groovy.sandbox.impl.Checker.checkedCall(Checker.java:146) at org.kohsuke.groovy.sandbox.impl.Checker.checkedCall(Checker.java:123) at com.cloudbees.groovy.cps.sandbox.SandboxInvoker.methodCall(SandboxInvoker.java:15) at WorkflowScript.run(WorkflowScript:17) at Unknown.Unknown(Unknown) at cps.transform(Native Method) at com.cloudbees.groovy.cps.impl.ContinuationGroup.methodCall(ContinuationGroup.java:69) at com.cloudbees.groovy.cps.impl.FunctionCallBlock$ContinuationImpl.dispatchOrArg(FunctionCallBlock.java:106) at com.cloudbees.groovy.cps.impl.FunctionCallBlock$ContinuationImpl.fixArg(FunctionCallBlock.java:79) at sun.reflect.GeneratedMethodAccessor290.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at com.cloudbees.groovy.cps.impl.ContinuationPtr$ContinuationImpl.receive(ContinuationPtr.java:72) at com.cloudbees.groovy.cps.impl.ClosureBlock.eval(ClosureBlock.java:40) at com.cloudbees.groovy.cps.Next.step(Next.java:58) at com.cloudbees.groovy.cps.Continuable.run0(Continuable.java:145) at org.jenkinsci.plugins.workflow.cps.SandboxContinuable.access$001(SandboxContinuable.java:19) at org.jenkinsci.plugins.workflow.cps.SandboxContinuable$1.call(SandboxContinuable.java:33) at org.jenkinsci.plugins.workflow.cps.SandboxContinuable$1.call(SandboxContinuable.java:30) at org.jenkinsci.plugins.scriptsecurity.sandbox.groovy.GroovySandbox.runInSandbox(GroovySandbox.java:106) at org.jenkinsci.plugins.workflow.cps.SandboxContinuable.run0(SandboxContinuable.java:30) at org.jenkinsci.plugins.workflow.cps.CpsThread.runNextChunk(CpsThread.java:164) at org.jenkinsci.plugins.workflow.cps.CpsThreadGroup.run(CpsThreadGroup.java:271) at org.jenkinsci.plugins.workflow.cps.CpsThreadGroup.access$000(CpsThreadGroup.java:71) at org.jenkinsci.plugins.workflow.cps.CpsThreadGroup$2.call(CpsThreadGroup.java:180) at org.jenkinsci.plugins.workflow.cps.CpsThreadGroup$2.call(CpsThreadGroup.java:178) at org.jenkinsci.plugins.workflow.cps.CpsVmExecutorService$2.call(CpsVmExecutorService.java:47) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at hudson.remoting.SingleLaneExecutorService$1.run(SingleLaneExecutorService.java:112) at jenkins.util.ContextResettingExecutorService$1.run(ContextResettingExecutorService.java:28) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745)

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
