Install Golang in Docker

Golang (also known as Go) is a programming language developed by Google. Its main features are concise syntax, excellent performance, and strong concurrency capabilities. Golang has good applications in fields such as web development and system programming. Docker is a fast, lightweight container solution. Now, we will introduce how to install Golang in Docker.

Step 1: Get the Ubuntu image from the official Docker repository

First, we need to get the Ubuntu image from the official Docker repository. Enter the following command in the terminal window:

sudo docker pull ubuntu

This will download the Ubuntu image from the official Docker repository.

Step 2: Create a Docker container and get into it

Next, we will create a new Docker container and get into it. Enter the following command in the terminal window:

sudo docker run -it --name mygolang ubuntu /bin/bash

This will create a new Docker container named "mygolang" and mount it in the terminal window of /bin/bash.

Step 3: Install Golang

Now, we can install Golang in the Docker container. Enter the following command in the terminal window:

sudo apt-get update
sudo apt-get install golang

This will install Golang using apt-get.

Step 4: Set the GOROOT and GOPATH environment variables

After installing Golang, we need to set the GOROOT and GOPATH environment variables. GOROOT refers to the installation path of Golang, and GOPATH refers to the path of other projects. Enter the following command in the terminal window:

export GOROOT=/usr/lib/go
export GOPATH=$HOME/work

This will set GOROOT to /usr/lib/go, and GOPATH will point to our working directory.

Step 5: Test Golang installation

Now we can test whether Golang was successfully installed. Enter the following command in the terminal window:

go version

If installed correctly, the version number of Golang will be displayed.

Step 6: Exit the Docker container
