How to smoothly deploy Golang applications

With the rapid development of Internet technology, various development languages ​​​​are emerging one after another, and one of the most popular languages ​​​​is Golang. Golang is an efficient programming language developed by Google that allows developers to easily write high-performance applications. However, when we need to deploy these applications, we often encounter many problems, such as how to ensure smooth deployment, how to manage different versions of applications, and so on. This article will talk about how to smoothly deploy Golang applications.

1. Deploying Golang applications

Before deploying Golang applications, we need to ensure that our applications fully comply with the standards of the Golang language. This means we need to use the gofmt tool to format our code, use the golint tool to check the verbosity of the code, and so on. After ensuring that our Golang application complies with the language standards, we can start deploying our application.

Before deploying a Golang application, we need to ensure that we have all the necessary tools and environments ready. This includes:

1. Online Server: We need an online server to host our application.
2. Git: We need to use Git tools to collaboratively develop our applications.
3. Go: We need to install the Golang environment on the server so that our application can be compiled and run.
4. System operation and maintenance tools: We need to use some system operation and maintenance tools to manage the server, such as systemctl, supervisor, etc.

After ensuring that we have these tools and environment ready, we can start deploying our application. For the deployment of Golang applications, we can use different deployment methods, as follows:

1. Direct deployment: We can deploy the application directly to the server and use the ssh tool to connect to the server to run our app. This method is simple and fast, suitable for small applications.
2. Docker deployment: We can use Docker to deploy our applications. This approach allows our applications to run in different environments and allows for better management of our applications.

No matter which method is used, we need to pay attention to the requirements for smooth deployment, which is what we will discuss next.

2. Smooth deployment

The purpose of smooth deployment is to minimize the service interruption of the application without interrupting the use of existing users. To achieve smooth deployment, we need to take the following measures:

1. Before releasing a new version, test the new version: Before releasing the new version to the production environment, we need to test the performance, reliability, etc. of the new version , to ensure that the new version can run properly.
2. Prepare the backup environment: When releasing a new version, we need to back up the production environment so that we can quickly restore to the previous environment if a problem occurs.
3. Use rolling update method: We can use rolling update method to update different parts of the application and gradually introduce the new version into the production environment to avoid large-scale service interruption.

With the above measures, we can ensure smooth deployment of our applications.

3. Deployment Management

After smooth deployment, we need to manage different versions of the application so that we can switch to the previous version at any time. To achieve this, we need to take the following measures:

1. Write deployment scripts: We can write deployment scripts that allow us to quickly deploy different versions of the application and perform rollback operations quickly.
2. Use version controller: We can use version controller to manage our application and record the changes of each version.
3. Real-time monitoring of applications: We need to constantly monitor our applications in order to detect and handle abnormalities in a timely manner.

With the above measures, we can better manage different versions of applications and handle exceptions in a timely manner.

Conclusion

Through this article, we can learn about the deployment and management methods of Golang applications. In order to ensure smooth deployment of the application, we need to test the new version before releasing it and adopt a rolling update method to provide a complete backup mechanism for our application. At the same time, we need to adopt some management measures, such as writing deployment scripts, using version controllers, real-time monitoring of applications, etc., to better manage our applications.
