How to retry a Jenkins Pipeline stage with an agent condition

Using Jenkins Ask a question
1

in out company we execute parallel test executions when each test gets it’s own node… The nodes are an aws spot type agents, which by policy can be taken by aws and get terminated while in progress. We want to re execute the stages which nodes were terminated by aws and we came across the Pipeline retry step retry-the-body-up-to-n-times step with condition, which can be set to retry a pipeline stage in case agent was interrupted. To use it we need to pass array of Nested Choice of Objects - in my case single object of “agent” i tried to execute the next code with different syntax attempts:

import hudson.model.*
import jenkins.model.*

pipeline {
    agent { label 'aws-fleet-spot-small' }
    stages {
        stage('test parallel') {
            steps {
                script {
                    def stepsForParallel = [:]
                    stepsForParallel["stage1"] = {
                        retry(count: 3, conditions: [agent{ label 'aws-fleet-spot-small' }]){
                            node("aws-fleet-spot-small") {
                                stage("stage1") {
                                    script {
                                        echo ('stage11111')
                                    }
                                }
                            }
                        }
                    }
                    stepsForParallel["stage2"] = {
                        node("aws-fleet-spot-small") {
                            stage("stage2") {
                                script {
                                    echo ('stage2222')
                                }
                            }
                        }
                    }
                    parallel stepsForParallel
                }
            }
        }
    }
}

or

retry(count:3, conditions:[agent])

i also found this stuck overflow thread Retry with condition jenkins pipeline and use the code :

import org.jenkinsci.plugins.workflow.support.steps.AgentErrorCondition
retry(count: 3, conditions: [new AgentErrorCondition()){

or

retry(count:3, conditions: [AgentErrorCondition])

which by the jenkins code, expects ErrorCondition implementing classes arr/list as a value to the conditions key but i get compilation exceptions

Can anyone please suggest me the right syntax or point to a working example?

jenkins

Working example in the buildPlugin library that is used to build Jenkins plugins on ci.jenkins.io:

Thanks for your reply…
i executed → 

import hudson.model.*
import jenkins.model.*

pipeline {
    agent { label 'aws-fleet-spot-small' }

                    stepsForParallel["stage1"] = {
                        retry(count: 3, conditions: [kubernetesAgent(handleNonKubernetes: true)]){

Do i need to use a specific plugin for it ?
I tried to look for kubernetesAgent object doc but couldn’t find it , Can u please point me to “agent” which is another option conditions can receive?

@borik11 This question was asked last year, but I would like to know if you were able to make it work?

@chaleao @borik11 Were you able to figure out the correct syntax for this?

The correct syntax is used very frequently on ci.jenkins.io in buildPlugin. Refer to: line 51 of buildPlugin

The kubernetesAgent step is provided by the kubernetes plugin…

It is documented in the retry step. The Pipeline syntax snippet generator for retry will help you generate the correct syntax.

Unfortunately. I wasn’t able to make it work
