[英]Jenkins multibranch pipeline triggers pipeline on unrelated branches
我在使用 JenkinsFile 和 GIT 插件時遇到了 Jenkins 多分支管道問題。
問題是每次推送到暫存分支也會觸發 master 的管道。 所需的行為是推送到登台分支僅觸發用於登台的管道,而推送到主分支僅觸發主管道
這是我的 JenkinsFile
#!/usr/bin/env bash
pipeline {
agent any
triggers {
pollSCM('*/1 * * * *')
}
environment {
GCLOUD_PATH="/var/jenkins_home/GoogleCloudSDK/google-cloud-sdk/bin"
}
stages {
stage('Git Checkout'){
steps{
// Clean Workspace
cleanWs()
// Get source from Git
git branch: 'staging',
credentialsId: ****',
url: 'git@github.com:***/****.git'
}
}
stage('Update Staging') {
when {
branch 'staging'
}
environment{
INSTANCE="***"
}
steps {
sshagent(credentials : ['****']) {
sh 'ssh -tt -o StrictHostKeyChecking=no jenkins@"${INSTANCE}" sudo /opt/webapps/****/deploy.sh firstinstance'
}
}
}
stage('Update Production') {
when {
branch 'master'
}
environment{
gzone="us-central1-a"
}
steps {
sh '''
#!/bin/bash
echo "${BRANCH_NAME}"
export instances=$("${GCLOUD_PATH}"/gcloud compute instances list --filter="status:(running) AND tags.items=web" --format="value(name)")
FIRST=1
for instance in ${instances}
do
echo "### Running Instance: ${instance} ###"
if [[ $FIRST == 1 ]]; then
echo "first instance"
${GCLOUD_PATH}/gcloud compute ssh jenkins@${instance} --zone ${gzone} '--ssh-flag=-tt -i /root/.ssh/id_rsa -o StrictHostKeyChecking=no' --command="echo first"
else
${GCLOUD_PATH}/gcloud compute ssh jenkins@${instance} --zone ${gzone} '--ssh-flag=-tt -i /root/.ssh/id_rsa -o StrictHostKeyChecking=no' --command="sudo uptime"
fi
FIRST=0
done
'''
}
}
}
post {
success {
cleanWs()
}
}
}
我將分享一些日志:這是 master 分支的日志

這是 master 分支的日志,但只有 staging 有一個新的提交:

即使主分支上的頭部沒有更改,請注意“發現更改”
詹金斯版。 2.190.1 Git 插件 4.0.0 版 Git 客戶端插件 2.9.0 版
我使用這個插件 - https://github.com/lachie83/jenkins-pipeline ,它對我來說很好用。 每個分支都需要單獨的 if 塊,然后是其中的 stage 塊。 下面的例子:
#!/usr/bin/groovy
@Library('https://github.com/lachie83/jenkins-pipeline@master')
def pipeline = new io.estrado.Pipeline()
def cloud = pipeline.getCloud(env.BRANCH_NAME)
def label = pipeline.getPodLabel(cloud)
// deploy only the staging branch
if (env.BRANCH_NAME == 'staging') {
stage ('deploy to k8s staging') {
//Deploy to staging
}
}
// deploy only the master branch
if (env.BRANCH_NAME == 'master') {
stage ('deploy to k8s production') {
//Deploy to production
}
}
我認為您的 Jenkinsfile 中有一些邏輯上的遺漏。 按照目前的情況,您可以輪詢 SCM 以了解更改。 如果檢測到任何更改,第一階段“Git Checkout”將檢出暫存分支(始終)。 然后你有另一個階段,如果分支是“暫存”(它是這樣,因為它是硬編碼來檢查上面的那個分支)等等。這將是首先要修復的 - 如果檢測到 SCM 更改,檢查正確的分支. 如何 - 有幾個選項。 我通常在“選項”中使用“skipDefaultCheckout()”,並在我的第一個管道階段使用顯式結帳:
steps {
sshagent(['github-creds']) {
git branch: "${env.BRANCH_NAME}", credentialsId: 'github-creds', url: 'git@github.com:x/y.git'
}
}
第二件事是您嘗試將兩個不同的分支處理壓縮到一個 Jenkinsfile 中。 這不是應該做的。 Jenkins 將使用來自給定分支的 Jenkinsfile - 只需確保暫存上的 Jenkinsfile 包含您希望它包含的內容,與 master 上的 Jenkinsfile 相同。
希望能幫助到你。
