# Integrating GitHub API Calls with Shell Scripts on AWS EC2

### Introduction :

Automation is the most important step in Devops. In this blog , we’ll interact with the GitHub API to read the list of user’s public repositories and created date using shell scripts , running them on an AWS EC2 instance.

## Step-1 : Create an ec-2 instance.

* First login to AWS console.
    
* Search ec2 instance.
    
* Click on launch instance.
    

### Configure ec2 instance :

* Enter a name for your instance.
    
* Select Ubuntu as an operating system.
    
* Select Instance type as per your needs. Ex: t2.micro
    
* Select a key-pair for secure connection.
    
    * If you had a pair select that from dropdown else ,
        
    * click on create new key pair.
        
* Click on launch instance.
    
* Once the instance is ready connect to instance by the below command on linux or if u had windows use MobaXterm.
    
    ```plaintext
    ssh -i /path-to-key-value-pair.pem Ubuntu@ec2-instance-ip-address
    ```
    

## Step-2 : Create a GitHub API token.

* Login to GitHub and open settings tab.
    
* Select Developer Settings available on side bar.
    
* Click on personal access token and then click on tokens classic.
    
* Click on Generate new token for classic and give authentication password.
    
* Select necessary checkboxes to give access and then click on generate token.
    
* **Copy token**.
    

## Step-3 : Create a shell script for GitHub API calls.

* First create a scripting file.
    

```plaintext
vim filename.sh
```

* Write the below code in the filename.sh
    

```bash
#!/bin/bash

api=https://api.github.com #main api of github

list_repo_url=$api/users/$username/repos #entire url formation

echo "username $username" #printing the username given from export command
echo  "url is $list_repo_url" #printing the entire url .

arr=$(curl -L \
  -H "Accept: application/vnd.github+json" \
  -H "Authorization: Bearer $token" \  
  H "X-GitHub-Api-Version: 2022-11-28" \
  $list_repo_url | jq -c '.[]') #sending request and storing the json compact format in array


echo $arr | while ISR= read i ;do
        echo $i | jq -r '"Name : \(.name)     Created at : \(.created_at)"'  #printing repo name and created date.
done;
```

* Save and exit the file.
    

## Step-4 : Executing Script.

* Insert username and token value by export command.
    

```bash
export username=github-username
```

```bash
export token=your-github-api-token
```

* Change permission for file to execute by user.
    

```bash
chmod 777 filename.sh
```

* Execute the script.
    

```bash
/filename.sh
```

### Conclusion :

In this blog, we explored how to integrate the GitHub API with Shell scripts on an AWS EC2 instance, demonstrating a practical approach to automating tasks like fetching repositories data and just displayed name and created-date information.
