Lab: Deploying with Multi Stage Pipeline

CI/CD Jenkins
#1

Could someone please help me understand what is wrong in the jenkinsfile? Also, as per the solution I am supposed to just use sh 'git pull' which doesnt seem to work as well. As far as I understand I need to somehow get the git credentials also in the jenkinsfile, but I assume it is being handled already by the lab environment.

figured out the issue. Jenkinsfile syntax was incorrect. Missing / in customWorkspace. Yet I am unable to understand how the git pull works without providing a credential?

Corrected Jenkinsfile:

pipeline {
  agent none

  stages {
    // DEV
    stage('Build Dev') {
      agent {
        label {
          label 'dev'
          customWorkspace "/opt/go-app"
        }
      }
      steps {
        sh 'git pull http://git-server:3000/bob/go-app.git dev'
      }
    }
    stage('Test Dev') {
      agent {
        label {
          label 'dev'
          customWorkspace "/opt/go-app"
        }
      }
      steps {
        sh 'go test ./...'
      }
    }

    stage('Deploy Dev') {
      agent {
        label {
          label 'dev'
          customWorkspace "/opt/go-app"
        }
      }
      steps {
        script {
          withEnv(['JENKINS_NODE_COOKIE=do_not_kill']) {
            sh 'go run main.go &'
          }
        }
      }
    }
    // PROD
    stage('Build Prod') {
      agent {
        label {
          label 'prod'
          customWorkspace "/opt/go-app"
        }
      }
      steps {
        sh 'git pull http://git-server:3000/bob/go-app.git master'
      }
    }
    stage('Test Prod') {
      agent {
        label {
          label 'prod'
          customWorkspace "/opt/go-app"
        }
      }
      steps {
        sh 'go test ./...'
      }
    }

    stage('Deploy Prod') {
      agent {
        label {
          label 'prod'
          customWorkspace "/opt/go-app"
        }
      }
      steps {
        script {
          withEnv(['JENKINS_NODE_COOKIE=do_not_kill']) {
            sh 'go run main.go &'
          }
        }
      }
    }
  }
}

It will be because there is already an initialized git repo in /opt/go-app and the credentials must already be present in the jenkins server.

The original error is because opt/go-app is a directory relative to the working directory of the build agent (which isn’t /) and that directory more than likely doesn’t exist, let alone being an initialized repo directory.
