Deploy Go Language

This guide covers launching and using Go Language from AWS Marketplace.

Prerequisites

• An AWS account with permission to subscribe to Marketplace products and launch EC2 instances.
• An EC2 key pair for administrative access.

Step 1 — Subscribe & launch

1. On the AWS Marketplace listing, choose Continue to Subscribe → Continue to Configuration → Continue to Launch.
2. Select an instance type and your key pair.
3. Configure the security group (see the ports below) and launch.

Step 2 — Security group / ports

Open port 22 (SSH) restricted to your IP, plus any application ports.

Step 3 — Connect

ssh -i "your-key.pem" ec2-user@<PUBLIC_IP>

If you get a key-permission error: chmod 400 your-key.pem.

Step 4 — Access the application

To verify the installation, follow the below instructions

Step 1. Connect to SSH

• Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.
• In the navigation pane, choose Instances.
• Select the instance and choose Connect.
• Choose SSH Client
• Copy the SSH command and paste it into the terminal.

ssh ec2-user@publicIP -i [Path of key pair file]

If it shows an access denied message run the following command, then run the above command again to connect via ssh.

chmod 400 [Path of key pair file]

Once launched in the Amazon EC2 Service, please connect to the instance via an SSH client using the ec2-user with the key pair associated at launch. Once connected as the ec2-user user, you will be able to sudo to the root user.

Step 2. Verify the installation

Follow the steps to verify the Go installation

1. Login with ssh
2. Type the below command to check the version

go version

You will see the responses as shown below.

How to use Go language in the terminal

1. After connecting with ssh.
2. Run the below command to create a file,

sudo nano helloworld.go

3. After that paste the code in the file given below:

package main
import "fmt"
func main() {
fmt.Printf("Hello World\n")
}

4. Run the below command:

go run helloworld.go

5. If you get the “Hello, world!” in output then your Go Language is working properly.

To monitor and assess application functions

a. Navigate to your Amazon EC2 console and verify that you’re in the correct region.

b. Choose Instances and select your launched instance.

c. Select the server to display your metadata page and choose the Status checks tab at the bottom of the page to review if your status checks passed or failed.
