jenkinsfile

Jenkinsfile

在gitlab所要发布的项目根目录中添加如下文件，当然也可以放到gitlab的其它位置（需在Pipeline script from SCM更改git拉取的位置）：

jenkinsfile内容

创建Pipeline，并使用SCM

点击New Item

输入item name,并点击流水线,最后点OK

在Pipeline里面选择Pipeline script from SCM，并选择自己存放jenkinsfile的git位置，并点击保存

当然，你也可以直接选择pipeline script:

运行Pipeline

点击自己创建的项目,选择Buiild with Parameters：

输入内容(jenkinsfile中已有默认值)，点击build

如果Pipeline使用的g不是scm,而是pipeline script，有一些差别，脚本如下：

pipeline {
    agent {
        node {
            label 'Jenkins_slave'
