How to repeat a stage in Jenkins Workflow

Question

I'm trying to use Jenkins on Cloudbees to automate deployment of my software. I setup my workflow as following.

There may be times I want to redeploy. (assuming that stage takes a manual input parameter). How do I do that in workflow ? Here is my Groovy script.

def src = 'https://git.repo.url/proj.git' stage 'Build' node { env.JAVA_HOME="${tool name: 'Pre-Installed OpenJDK 8 (Latest) on DEV@Cloud nodes', type: 'hudson.model.JDK'}" sh 'javac -version' git credentialsId: 'abcdef', url: src sh 'ant -f build.xml proj.jar report' } stage 'Generate Release Version' input message: 'Create Tar and Push to S3', ok: 'Generate Release' node { // TODO } stage 'QA Approved' input message: 'Enter a Tag Name to approve this build and tag in GIT', ok: 'Approve and Tag', parameters: [[$class: 'StringParameterDefinition', defaultValue: '', description: 'Eg: Sprint73', name: 'TAG_NAME']] node { // TODO } stage 'DevOps - Ansible' input message: 'Release to Production', ok: 'Release' node { // TODO }

I tried using Job Chaining using Build Pipeline instead of Workflow so that I can repeat stages, but thats another story with too many jobs.

This should be resolved with "checkpoint" plugin. But currently this is still not possible in OSS version but voting is gooing on at their issue tracker JENKINS-33846. Feel free to submit your vote! — Zigac

This is only possible in the enterprise version of Jenkins. As @jesse-glick pointed out, you have the Checkpoint Plugin available there, see the documentation.

There's is currently no plan to support this feature in the OSS-version according to CloudBees. See this issue: JENKINS-33846

Supposing it is the last (Ansible) stage you want to be able to restart from, you could place a checkpoint just before it.

checkpoint 'about to deploy' stage 'DevOps - Ansible' input message: 'Release to Production', ok: 'Release' node { // TODO }

If you want to deploy to a selectable target, you could use input:

checkpoint 'about to deploy' stage 'DevOps - Ansible' def target = input message: 'Where to release?', parameters: [[$class: 'StringParameterDefinition', name: 'target']] node { // TODO }

The more complicated scenario is that you want to always deploy to a standard target the first time around, but when resuming from a checkpoint you want to ask the user for an alternate target. For that you need to know when you are resuming. Currently checkpoint does not offer this information directly (CJP-1620 in the CloudBees internal issue tracker), but there is a workaround:

def origBuildNumber = env.BUILD_NUMBER checkpoint 'about to deploy' stage 'DevOps - Ansible' def target if (origBuildNumber == env.BUILD_NUMBER) { // original target = 'production' } else { // resumed target = input message: 'Where to release?', parameters: [[$class: 'StringParameterDefinition', name: 'target']] } node { // TODO }
