jenkins-pipeline - Jenkinsfile 的 sshagent 块内的 Shell 变量

问题描述

我有这个 sshagent 代码块：

            sshagent(['ssh_key.hashed']) {
              sh """
              ssh -o StrictHostKeyChecking=no -l user example.com <<EOF
              today=`date +%Y-%m-%d`
              drush -r /var/www/html/example.com sql-dump --gzip > /var/www/html/example.com/backups/example_prodDB-jenkins-${today}.sql.gz
              EOF
              """.stripIndent()
            }

如您所见，真正的目的是获取 drupal 数据库的 db 转储。现在，如果在常规 shell 脚本上使用，它将起作用。

我需要这样写，因为我将$today在另一行代码中重用 shell 变量。

在 jenkinsfile 中，它似乎被解释为基于错误的 groovy 变量：

解决方案

经过大量的在线搜索和反复试验，发现这个有用的参考https://code-maven.com/jenkins-pipeline-environment-variables

我不知道这是否是正确的方法，但它有效。

所以总而言之，我必须添加一个环境变量并在我的“sshagent”中添加使用它

发布有效的示例 Jenkinsfile。

pipeline {
   agent any

   stages {
      stage('Dump Prod DB') {
           environment {
               today = sh(script: 'date +%Y-%m-%d', , returnStdout: true).trim()
           }
         steps {
            sshagent(['promet_key.hashed']) {
              sh """
              ssh -o StrictHostKeyChecking=no -l user example.com <<EOF
              drush -r /var/www/html/example.com sql-dump --gzip > /var/www/html/example.com/backups/example_prodDB-jenkins-${today}.sql.gz
              EOF
              """.stripIndent()
            }
         }
      }
   }
}
