[英]Parallel checkout in declarative Jenkins pipeline on multiple nodes
我正在為從Gitlab觸發的CI構建開發聲明式Jenkins管道。 我現在所擁有的:
// variable definitions
pipeline {
agent none
parameters {
string(defaultValue: 'develop',
description: 'Commit ID or branch name to build',
name: 'branch',
trim: false)
}
stages {
stage('Checkout') {
parallel {
stage ('Windows') {
agent {
label 'build' && 'windows'
}
steps {
script {
def checkout_ext = [[$class: 'CleanCheckout'],
[$class: 'CleanBeforeCheckout']] // calls git clean -fdx and git reset --hard
if (env.gitlabActionType == "MERGE"){
checkout_ext.add([$class: 'PreBuildMerge',
options: [ mergeRemote: "origin",
mergeTarget: "${env.gitlabTargetBranch}"]])
}
}
checkout([
$class: 'GitSCM',
branches: [[name: "${params.branch}"]],
userRemoteConfigs: [[ url: "${git_url}", credentialsId: "${git_credentials_id}" ]],
extensions: checkout_ext
])
}
}
stage('Linux') {
agent {
label 'build' && 'linux'
}
steps {
script {
def checkout_ext = [[$class: 'CleanCheckout'],
[$class: 'CleanBeforeCheckout']] // calls git clean -fdx and git reset --hard
if (env.gitlabActionType == "MERGE"){
checkout_ext.add([$class: 'PreBuildMerge',
options: [ mergeRemote: "origin",
mergeTarget: "${env.gitlabTargetBranch}"]])
}
}
checkout([
$class: 'GitSCM',
branches: [[name: "${params.branch}"]],
userRemoteConfigs: [[ url: "${git_url}", credentialsId: "${git_credentials_id}"]],
extensions: checkout_ext
])
}
}
}
}
}
}
結帳階段有些復雜。 如果gitlabActionType
為MERGE
,則首先嘗試合並到目標分支中,以確保合並請求不會破壞其中的任何內容。
這兩個操作系統的代碼相同。 我想避免代碼重復,但是無法找出正確的語法。
我嘗試將結帳步驟的定義移至全局變量,但出現語法錯誤。
def checkout_step = {
script {
...
}
checkout (... )
}
pipeline {
...
stages {
stage('Checkout') {
parallel {
stage ('Windows') {
agent {
label 'build' && 'windows'
}
steps {
checkout_step
}
}
stage ('Linux') {
agent {
label 'build' && 'linux'
}
steps {
checkout_step
}
}
}
}
}
}
如果添加steps
,則還會出現錯誤:
def checkout_step = steps {
script {
...
}
checkout (... )
}
pipeline {
...
stages {
stage('Checkout') {
parallel {
stage ('Windows') {
agent {
label 'build' && 'windows'
}
checkout_step
}
stage ('Linux') {
agent {
label 'build' && 'linux'
}
checkout_step
}
}
}
}
}
git_url = "git@gitserver.corp.com:group/repo.git"
git_credentials_id = 'aaaaaaa-bbbb-cccc-dddd-eefefefefef'
def checkout_tasks(os_labels) {
tasks = [:]
for (int i = 0; i < os_labels.size(); i++) {
def os = os_labels[i]
tasks["${os}"] = {
node("build && ${os}"){
def checkout_ext = [[$class: 'CleanCheckout'], [$class: 'CleanBeforeCheckout']] // calls git clean -fdx and git reset --hard
if (env.gitlabActionType == "MERGE"){
checkout_ext.add([
$class: 'PreBuildMerge',
options: [
mergeRemote: "origin",
mergeTarget: "${env.gitlabTargetBranch}"
]
])
/* using this extension requires .gitconfig with section [user for Jenkins]
Example
[user]
email = jenkins@builder
name = Jenkins
*/
}
checkout([
$class: 'GitSCM',
branches: [[name: "${params.branch}"]],
userRemoteConfigs: [[
url: "${git_url}",
credentialsId: "${git_credentials_id}"
]],
extensions: checkout_ext
])
}
}
}
return tasks
}
pipeline {
agent none
parameters {
string(defaultValue: 'develop',
description: 'Commit ID or branch name to build',
name: 'branch',
trim: false)
}
stages {
stage('Checkout') {
steps {
script {
def OSes = ["windows", "linux"]
parallel checkout_tasks(OSes)
}
}
}
}
}
聲明不帶def
git_url
和git_credentials_id
也很重要,以便函數可以讀取它們。
