使用凭证参数在多分支管道作业中从Jenkins凭证管理器读取问题难以解决

问题描述

我有一个詹金斯多分支管道作业，该作业使用Jenkinsfile中的秘密值:

I have a Jenkins multi branch pipeline job that uses a secret value in Jenkinsfile:

pipeline {
  agent any
  stages {
    stage('Test') {
      steps {
        echo "DOCKER_REGISTRY_USER is ${env.DOCKER_REGISTRY_USER_NSV}"
      }
    }
  }
}

机密值作为ID为DOCKER_REGISTRY_USER_NSV的机密文本存储在凭据管理器中:

The secret value is stored in Credentials Manager as secret text with the ID DOCKER_REGISTRY_USER_NSV:

如上所述，我正在尝试在Jenkinsfile中读取此值，但是我得到以下输出，为我的秘密打印出值null:

I'm trying to read this value in Jenkinsfile as shown above but I get the following output that prints out the value null for my secret:

[Pipeline] }
[Pipeline] // stage
[Pipeline] withEnv
[Pipeline] {
[Pipeline] stage
[Pipeline] { (Test)
[Pipeline] echo
DOCKER_REGISTRY_USER is null
[Pipeline] sh

我还尝试像这样在管道中引用机密文本:

I also tried referencing the secret text in my pipeline like this:

echo "DOCKER_REGISTRY_USER is ${DOCKER_REGISTRY_USER_NSV}"

但是运行Jenkins作业时出现此错误:

But then I get this error when running the Jenkins job:

groovy.lang.MissingPropertyException: No such property: DOCKER_REGISTRY_USER_NSV for class: groovy.lang.Binding
    at groovy.lang.Binding.getVariable(Binding.java:63)
    at org.jenkinsci.plugins.scriptsecurity.sandbox.groovy.SandboxInterceptor.onGetProperty(SandboxInterceptor.java:264)

我认为我需要将该凭证绑定到该工作，但是我看不到针对多分支管道工作(如Freestyle或Pipeline作业)执行此操作的选项.

I think I need to bind that credential to the job but I don't see an option to do that for a Multi-Branch Pipeline job, the way you can for a Freestyle or Pipeline job.

如何在多分支管道作业中使用秘密凭证?

How can I use a secret credential in a Multi Branch Pipeline job?

推荐答案

您可以使用 credentials()辅助方法来存档您的目的.

You can use credentials() helper method to archive your purpose.

pipeline {
    agent any

    environment {
        DOCKER_REGISTRY_USER = credentials('DOCKER_REGISTRY_USER_NSV') 
                               // put the ID of credential as credentials()'s parameter.
    }

    stages {

        stage('Test') {
            steps {
                echo "DOCKER_REGISTRY_USER is ${DOCKER_REGISTRY_USER}"
            }
        }
   }

}
