> Hello,
>
> My Jenkins is running in a kubernetes cluster and all pipelines run in pod.
> I'd like to limit the number of pipelines running in parallel: I'd like an
> executor limitation like we have when we were running all pipelines in
> master.
>
> I'm using lockable resources plugin.
> My expecting implementation was something like:
> pipeline {
> agent {
> kubernetes {
> label 'test-lock'
> yaml libraryResource('my-pod.yaml')
> }
> }
> options {
> lock(label: 'forge-executor', quantity: 1, variable:
> 'forgeExecutor')
> }
> stages {
> stage('echo') {
> steps {
> echo "OK"
> script {
> def outcome = input message: 'Please select',
> parameters: [
> [name: 'myChoice', description: 'My choice',
> choices: 'Choice 1\nChoice 2\nChoice 3', $class:
> 'ChoiceParameterDefinition']
> ]
> }
> }

> OK, the pipeline doesn't execute any stages if it cannot lock, but
> Kubernetes resources are used.
>
> I try to add when block with beforeAgent option in, but when block is only
> allowed at stage level.
> So I found a workaround: don't set any main agent and have one top stage
> with when condition:
> pipeline {
> agent none
> stages {
> stage('lock') {
> agent {
> kubernetes {
> label 'test-lock'
> yaml libraryResource('my-pod.yaml')
> }
> }
> when {
> beforeAgent true
> equals(expected: true, actual:true)
> }
> options {
> lock(label: 'forge-executor', quantity: 1, variable:
> 'forgeExecutor')
> }
> stages {
> stage('echo') {
> steps {
> echo "OK"
> script {
> def outcome = input message: 'Please select',
> parameters: [
> [name: 'myChoice', description: 'My
> choice', choices: 'Choice 1\nChoice 2\nChoice 3', $class:
> 'ChoiceParameterDefinition']
> ]
> }
> }
> }

> Where will I submit the issue? In lock plugin? in kubernets plugin? or in
> a core project?
