Jenkins Delivers Application to Virtual Machine¶

This document focuses on how Jenkins can deliver applications to a virtual machine. The process involves pulling code through the pipeline, testing, compiling, generating a package (such as a jar file), copying the installation package to the specified location on the corresponding server via scp or other tools, and replacing the old version of the package by executing commands or scripts remotely.

Steps¶

Prepare the image for pipeline execution

Since the pipeline needs to copy the package to the server where the application is located, tools such as scp, ansible, and sshpass are required. However, these tools are not installed in the default build image provided by the platform, so manual construction is needed.

Refer to Using Custom Toolchain in Jenkins for installation instructions.
Go to Workbench -> Pipelines -> Credentials, and create a credential of Access Token for the virtual machine

Go to Workbench -> Pipelines -> Pipelines, and create a pipeline

The pipeline steps are: pull code -> code build -> deploy application. Below is an example that omits the code build step:

pipeline {
  agent {
    kubernetes {
      inheritFrom 'base'
      yaml '''
      spec:
        containers:
        - name: ssh
          image: your-custom-tooling-image
          command: 
          - cat
'''
      defaultContainer 'ssh'
    }

  }  
  stages {
    stage('clone') {
      agent none
      steps {
        container('ssh') {
          git(branch: 'main', credentialsId: 'gitsecret1', url: 'https://gitlab.daocloud.cn/***/***.git')
        }

      }
    }

  stages {
    stage('build') {
      agent none
      steps {
        container('ssh') {
          sh 'build command'
        }

      }
    }
    stage('deploy') {
      agent none
      steps {
        container('base') {
          withCredentials([string(credentialsId:'sshpasswd',variable:'sshpasswd')]) {
            sh '''sshpass -p $sshpasswd ssh  -o StrictHostKeyChecking=no root@10.1.5.53 mv -f /usr/share/nginx/html/* /tmp
sshpass -p $sshpasswd scp  -r -o StrictHostKeyChecking=no ./* root@10.1.5.53:/usr/share/nginx/html/
sshpass -p $sshpasswd ssh  -o StrictHostKeyChecking=no root@10.1.5.53 nginx -s reload'''
          }

        }

      }
    }

  }
}

After successful creation, run the pipeline.
