Variables in Jenkins with environment

Credentials in Jenkins

Create Credentials

Manage Jenkins – Manage Credentials – System – Global credentials – Add Credentials

Use Credentials

New Item – Pipeline

Pipeline syntax generator

  • Dashboard – job_name – Pipeline Syntax
  • Sample Step : withCredentials: Bind credentials to variables
  • Bindings Username and password
pipeline {
    agent any
    stages {
        stage('credentials') {
            steps {
                withCredentials([usernamePassword(credentialsId: '5a04e3aa-b4bc-45f5-8a54-bde5363e7906', passwordVariable: 'user_password', usernameVariable: 'user_name')]) {
                    echo user_name
                    echo user_password
                }
            }
        }

Jenkins hide the user credentials, but we can use to access end point using the credentials
