How to automatically deploy Git code using Jenkins

Jenkins is a popular open source automation server tool that can be used for continuous integration and continuous deployment of applications. With Jenkins, you can easily automate testing, building and deploying your code. In this article, we will learn how to automatically deploy Git code using Jenkins.

Preparation:

1. Install Jenkins

Install Jenkins on a local or remote server. Installing Jenkins is very simple, just follow the instructions.

2. Install Git plug-in

Open the Jenkins control panel, click "Plug-in Management", search for and install the Git plug-in in "Optional Plug-ins".

3. Configure Git

Configure Git in Jenkins. Git needs to be configured as source control for use by Jenkins. Multiple Git source control can be configured. In the Jenkins panel, click "System Management", select "Global Tool Configuration", and add the path to Git and optional username and password in the "Git" section.

4. Create Jenkins Job

Create a new Job in Jenkins. Click "New Task" in the Jenkins control panel, enter the task name and select "Build a Free Style Software Project".

Practical operation:

1. Configure Git source code control in Jenkins

In Jenkins Job, click "Source Code Management" and select Git as the source Code control system. Fill in the URL and branch information of the Git repository into the corresponding text boxes.

In "Build Trigger", select "Poll SCM" and configure the polling interval so that Jenkins can automatically detect any source code changes within a specific interval.

2. Set build steps

In Jenkins Job, click "Build Steps" and add a "Batch Command" build step for building the code.

In the "Execute Windows Batch" build step, enter the following commands:

git pull
npm install
npm run build

These commands will check out the latest version of the Git repository, install the necessary dependencies, and build the application.

3. Automatically distinguish test steps

In Jenkins Job, click "Build Steps" and add a "Batch Command" build step for executing tests.

In the "Execute Windows Batch" build step, enter the following commands:

npm run test

These commands will run the application's tests and generate a test report.

4. Configure automatic deployment

In the Jenkins Job, click "Post Build Step" and add the "Deploy to Container" build step.

In the "Deploy to Container" build step, fill in the deployment information, including server URL, user name, password, etc.

Click "Save" to save the Jenkins Job configuration.

Now, Jenkins will automatically build and test the application when source code changes. Once the build and test are successful, Jenkins will automatically deploy the application to the specified server.

Conclusion:

Using Jenkins to automatically deploy Git code is a powerful and simple way to save time and effort. Using this process, Jenkins will automatically build, test, and deploy applications, speeding up the iteration and deployment process. Consider integrating this process into your development pipeline for faster, higher-quality code delivery.
