Hello World

As the first step for Golang learning, a hello world application is expected.

The needed files for this project are a Dockerfile and a simple golang sample.

How to run

You can build the application on local or either use docker to ease the process. Here, we will only cover the Dockerfile-through process.

Place yourself on the terminal, at the same level as this directory, and run:

docker build -t <simple project name> .
docker run <simple project name>

Reference Index

For this mini-project we need fmt package, which implements formatted I/O functions analogous to C's printf and scanf. The format 'verbs' are derived from C's but are simpler. This way we will handle output for our Hello World.

To import this package we simply do the following [Ref. 1]:

import "fmt"

We also use our main function for printing our text through the fmt.Println function [Ref. 2].

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