A brief analysis of how to install and configure Golang on Alpine

Alpine is a lightweight, security-oriented Linux operating system. Installing and using Golang on Alpine allows you to complete Golang programming work in a smaller space and maintain higher security. In this article, we will detail how to install and configure Golang on Alpine.

Step 1: Install basic components

Before installing Golang on Alpine, you need to install some basic components, such as build-essential, libc6-dev and git, etc. These tools are necessary for compiling Golang programs. You can install them using the following command:

apk add build-base
apk add git

Step 2: Download the Golang installation package

Visit [golang.org](https://golang.org/dl/) to download what you need Golang Linux version. What we download here is golang version 1.15.1.

wget https://dl.google.com/go/go1.15.1.linux-amd64.tar.gz

Step 3: Install Golang

After downloading, use the following command to decompress the file and install Golang to /usr/local.

tar -zxvf go1.15.1.linux-amd64.tar.gz -C /usr/local

Step 4: Configure environment variables

In order for the system to find Golang, you need to add the Golang installation directory to your system path. You can use the vi editor to open /etc/profile and enter the following content.

export PATH=$PATH:/usr/local/go/bin

Save the file and update the modifications using the following commands.

source /etc/profile

Step 5: Test Golang installation

Finally, we can test whether Golang is installed successfully by creating a simple hello world program. Create a file named hello.go with the following content.

package main

import "fmt"

func main() {
    fmt.Println("Hello, World!")
}

Compile and run the program using the following command:

go run hello.go

If everything goes well, you will see the output of Hello, World message in the terminal.
