Hi Team,
I am getting an error while running the Jenkins file tp build and push the docker image into docker hub .
you can reveiw my code github : https://github.com/iakshaykr/webapp.git (using jenkins_pipe branch not master branch )
Jenkinsfile : 
pipeline {
    environment {
        registry= "iakshaykr/webapp"
        registryCredential= 'dockerhub'
    }
    agent { dockerfile true }
    stages {
        stage('Bilding image') {
            steps {
             script {
                 docker.build registry + ":$BUILD_NUMBER"
              }
            }
        }
    }
}
