Jenkins:在全局环境部分使用 withCredentials

问题描述

I have a Jenkins pipeline with multiple stages that all require the same environment variables, I run this like so:

script {
    withCredentials([usernamePassword(credentialsId: 'COMPOSER_REPO_MAGENTO', passwordVariable: 'MAGE_REPO_PASS', usernameVariable: 'MAGE_REPO_USER')]) {
        def composerAuth = """{
            "http-basic": {
                "repo.magento.com": {
                    "username": "${MAGE_REPO_USER}",
                    "password": "${MAGE_REPO_PASS}"
                }
            }
        }""";
        // do some stuff here that uses composerAuth
    }
}

I don't want to have to re-declare composerAuth every time, so I want to store the credentials in a global variable, so I can do something like:

script {
    // do some stuff here that uses global set composerAuth
}

I've tried putting it in the environment section:

environment {
    DOCKER_IMAGE_NAME = "magento2_website_sibo"
    withCredentials([usernamePassword(credentialsId: 'COMPOSER_REPO_MAGENTO', passwordVariable: 'MAGE_REPO_PASS', usernameVariable: 'MAGE_REPO_USER')]) {
        COMPOSER_AUTH = """{
            "http-basic": {
                "repo.magento.com": {
                    "username": "${MAGE_REPO_USER}",
                    "password": "${MAGE_REPO_PASS}"
                }
            }
        }""";
    }
}

But (groovy noob as I am) that doesn't work. So what's the best approach on setting a globally accessible variable with credentials but only have to declare it once?

解决方案

You can use credentials helper method of the environment section. For "Username and passwrd" type of credentials it assigns 2 additional environment variables. Example:

environment {
  MAGE_REPO_CREDENTIALS = credentials('COMPOSER_REPO_MAGENTO')
  COMPOSER_AUTH = """{
      "http-basic": {
          "repo.magento.com": {
              "username": "${env.MAGE_REPO_CREDENTIALS_USR}",
              "password": "${env.MAGE_REPO_CREDENTIALS_PSW}"
          }
      }
  }"""
}
