Using Jenkins for continuous integration and automated deployment in Beego

In modern software development, continuous integration and automated deployment have become key development and operation and maintenance practices. When you use the Beego framework to develop web applications, how to perform continuous integration and automated deployment through Jenkins?

This article will introduce you to how to use Jenkins in Beego to achieve continuous integration and automated deployment.

Step One: Install Jenkins

First, you need to install Jenkins on your system. You can download and install the version suitable for your system from the official Jenkins website https://jenkins.io. After installing and starting Jenkins, you can visit http://localhost:8080/ in the browser to access the Jenkins web interface.

Step 2: Create a Jenkins Job

Creating a Job in Jenkins is very simple. Enter the main Jenkins page, click the "New Task" button on the left, and then enter the project name in the pop-up page. Next, you can choose to use a source code management tool to manage your source code. In this example we use Git. In order to use Git, you need to install Git on your system and add your project repository to your system.

After creating the Job, choose to add a "Build Step". In this example, we select a "Shell Command" build step to execute a script:

#!/bin/bash
cd $WORKSPACE
go build main.go

The purpose of this script is to build the application main.go in the project workspace. Please make sure the Go language is installed on your system.

Step 3: Set up automated deployment

In order to set up automated deployment, we need to install the SSH plug-in in Jenkins. In the left menu of the Jenkins main interface, select "Plug-in Management", search for "SSH Plug-in" in the search box, and install it.

Next, in the created Job page, select the "Post Build Steps" tab and select the "Send build artifacts over SSH" build step. In this step, you need to configure the SSH server and SCP plug-in to automatically upload the built binary file:

1. Configure SSH server

• Hostname: fill in the server IP Or domain name
• Username: Server login username
• Remote directory: Remote file directory path

2. Configure SCP plug-in

• Source files: The path of the completed file, such as $WORKSPACE/main
• Remove prefix: The project path prefix that needs to be removed. In the Linux system, if your project directory structure is /home/user/myproject, then you need to remove the "/home/user/" prefix and just fill in "myproject".
• Exec command: Remote command to execute. Here we use the ssh command to start the application.

cd /path/to/remote/directory
./main &

After completing these configurations, your Jenkins Job is set up. Whenever new code is pushed to the Git repository, Jenkins will automatically fetch the latest code from Git and build the application. Once the build is complete, Jenkins will automatically use the SSH plugin to upload the binary file to the server and start the application on the server.

In this article, we introduce how to use Jenkins to implement continuous integration and automated deployment of Beego applications. This will make your application development more efficient and save a lot of energy in your operation and maintenance work.
