In this tutorial, I will show you how to deploy **Golang** app to **Amazon EC2**. You will need an AWS account. [You can signing up for free](http://aws.amazon.com/free).

**1 — Setup EC2 instance**

Once you created you account, open the [AWS Management Console](https://console.aws.amazon.com/) and click on **EC2**:

Then, click on “**Launch Instance**” :

![](https://hackernoon.com/hn-images/0*ov5xrO6cwCpwtrAQ.)

Choose an **AMI** (**Amazon Machine Image**). We are going to choose “**Amazon Linux AMI 2017.03.1 5 (HVM), SSD Volume Type**” . The exact versions may change with time.

_Note_ : There are other Linux **AMI**s that you can use, which have **Go** and other software pre-installed, which you may use as a shortcut later. But for our purposes, if you start with a clean installation and configure everything yourself, you’ll be able to better understand how to administer and maintain your instances in future.

Next, we will choose the hardware configuration for our instance. So we will go with the lowest specs and cheapest configuration “**t2.micro**” which is enough for this tutorial:

Then click on “**Configure Instance Details**”. We left everything as default then click on “**Add Storage**”

Next, click on “**Add Tags**” to assigne a name to our instance:

Click on “**Configure Security Group**“. Then expose the port number your server will be listening on. For this demo, I have made an application which is listening on port 3000, Therefore, I enabled **HTTP port 3000** and I set the **source** column to ‘**Anywhere 0.0.0.0/0**’ .

![](https://hackernoon.com/hn-images/0*8F_EKfremhkeRZJ5.)

The settings above allows access to port **3000** from **anywhere**, and **SSH access** only from **anywhere.**

Now, click on “**Review And Launch**” then “**Launch**“.

When prompted for a **key pair**, you can either choose an existing key pair or create a new key pair. Save the **private key file** in a safe place. You’ll need to connect by **SSH** to your instance later.

When you’re ready, select “**Launch Instances**”:

Your instance is now launching and that may take a few minutes. Click the [**View your instances on the Instances page**](https://console.aws.amazon.com/ec2/home?#s=Instances) link and you will be redirected to your “**My Instances**” page, where you can monitor and configure your EC2 instance:

Wait until the instance state turns to “**running**” then use the **public DNS** to connect to your service via **SSH**.

**2 — Connect to AWS EC2 via SSH**

Now that we have connected to the instance, it’s time to install **Golang**.

**3 — Install Golang on EC2**

Once you’re connected to the instance, use **yum** configuration manager to install **Go**:

> sudo yum update -y

> sudo yum install -y golang

Now you need to set up **Go environment variables** for your project. Commonly you need to set 3 environment variables as **GOROOT**, **GOPATH** and **PATH**

![](https://avatars1.githubusercontent.com/u/10320205?s=400&v=4)

Note: all above commands will set the environment variables for your current session only. To make it permanent add above commands in **‘~/.bash\_profile’** file

At this step you’ve successfully installed and configured go language on your system.

Congratulation ! you have a working EC2 instance with Go.

**4 — The Go Application**

Note: You can skip this step if you have your own Go App ready to be deployed.

Put the following content in a file named “**app.go**” :

Run the app using the following commands:

> go run app.go

Finally, if you point your favorite web browser (not you IE) at your instance’s **public DNS name** you should see :

Congratulation ! you have deployed your first **Go** App to **AWS EC2** instance.

_Note_: In case your app is listening on different port than 3000, you can always add it to the security group assigned to your EC2 instance. Just go to EC2 menu, then click on “**Security groups**”

Click on “**Edit**” and follow the same steps described in **first section** of this tutorial.

**5 — Clean Up your instance**

After you’ve finished with the instance that you created for this tutorial, you should clean up by terminating the instance.
