How to deploy golang in gae

Essentially, Golang is a programming language developed by Google to solve practical problems in software development. The language has excellent performance and reliable multi-threading support. Golang's code compilation speed is very fast, and the generated binary files are also very small, which makes Golang one of the preferred languages ​​​​for many developers. If you want to deploy Golang code to the cloud or set up an environment to run on CentOS/Ubuntu, you can use Google's cloud computing platform GAE to deploy Golang.

In this article, we will introduce how to deploy Golang code on GAE and the detailed steps to install the Golang environment on CentOS/Ubuntu.

1. Deploy Golang code on GAE

1. Create a GAE project

First, you need to have a GAE account and create a new project on the console. During the process of creating a new project, you need to provide the name and ID of the project.

2. Create a Golang application

Create a Golang application on your local computer. It is recommended to use the provided SDK to create a local running environment and execute local operations through the commands supported by the SDK.

3. Configure the app.yaml file

After you have created the Golang application, you need to modify the app.yml file according to the project requirements. The purpose of this file is to tell GAE how to configure and run the application. For example:

runtime: go
api_version: go1

In the above code, the runtime and api_version attributes indicate that the application is written in Go and specifies the required API Version.

4. Upload the application

Finally, upload the application to GAE by using the gcloud CLI or management console.

gcloud app deploy app.yaml

5. Test application

The application has been successfully deployed to GAE and can be accessed via the URL in the browser, or via GAE background console to view the status of the application.

2. Install Golang on CentOS/Ubuntu

If you want to run Golang applications on CentOS/Ubuntu, you need to install the Golang runtime environment. The following are the steps to install Golang:

1. Download Golang

Before installing Golang, you first need to download Golang. The latest Golang version can be downloaded from the official website or from the installed software repositories of your Linux distribution. On Ubuntu, you can use the following command to install:

sudo apt-get install golang

2. Set environment variables

After installing Golang, you need to add its binary The path where the file is located to the system path. You can add the following code to the ~/.bashrc or ~/.bash_profile file:

export PATH=$PATH:/usr/local/go/bin

3. Verify installation

To verify whether Golang is installed successfully, you can run the following command:

go version

If the output is similar to "go version go1.12.5 linux/amd64", it means that Golang has been Installed successfully.

4. Writing and running applications

Now that Golang has been successfully installed on Ubuntu, you can start writing and running applications.

Summary

Golang is an efficient programming language with excellent performance and reliable multi-threading support. If you want to deploy Golang applications to the cloud or set up an environment to run on CentOS/Ubuntu, you can deploy Golang applications and install the Golang runtime environment on Ubuntu through GAE. Whether you are developing a new project or looking for alternatives in an old project, you can use Golang to improve development efficiency and code quality.
