kubernetes jenkins pipeline优化拉取大仓库性能指定分支+深度

news 来源：原创 2025/6/7 15:35:12

有时候我们历史的git仓库，提交了某个比较大的文件如果不限制 depth ，就会拉取所有的历史提交记录，这样在历史仓库比较大的时候 clone 非常之慢，而实际上我们只需要最新的代码来构建就行了，为了优化性能，我们可以配置指定拉取：

关键配置：

        stage('Check code') {echo("gitCommitId value is: ${gitCommitId}")// sh "sleep 10000"def scmVars = checkout([$class: 'GitSCM',branches: [[name: "${gitCommitId}"]],extensions: [[$class: 'CloneOption', depth: 1, shallow: true, noTags: true, honorRefspec: true, timeout: 3000]],userRemoteConfigs: [[credentialsId: "${gitlabCredential}",url: "${gitlabURL}",refspec: "+refs/heads/${gitCommitId}:refs/remotes/origin/${gitCommitId}"]]])commitHash = scmVars.GIT_COMMIT.take(8)echo("${commitHash}")}

上面的拉取方式只适合拉取分支的，如果还要兼容commitId，需要下面的配置：

// 判断是分支名还是 commit hash
def isCommitHash = gitCommitId ==~ /^[a-f0-9]{7,40}$/def scmVars = checkout([$class: 'GitSCM',branches: [[name: isCommitHash ? "${gitCommitId}" : "origin/${gitCommitId}"]],extensions: [[$class: 'CloneOption', depth: 1, shallow: true, noTags: true, honorRefspec: true, timeout: 3000]],userRemoteConfigs: [[credentialsId: "${gitlabCredential}",url: "${gitlabURL}",refspec: isCommitHash ? "+${gitCommitId}:refs/remotes/origin/target-commit" : "+refs/heads/${gitCommitId}:refs/remotes/origin/${gitCommitId}"]]
])
