In today’s software development landscape, efficiency and automation are paramount. GitHub Actions emerges as a pivotal tool, empowering developers to streamline workflows and enhance collaboration seamlessly. In this guide, we’ll walk through the process of automating the deployment of a TIC TAC TOE game using GitHub Actions, from setting up EC2 instances to integrating SonarQube and deploying to Kubernetes clusters.

Leveraging GitHub Actions for TIC TAC TOE Deployment

GitHub Repository: TIC TAC TOE GitHub Repository

Step 1: Launching an EC2 Instance

Sign in to AWS Management Console: Access the AWS Management Console with your AWS account credentials.
Access EC2 Dashboard: Navigate to the EC2 dashboard.
Launch Instances: Click on "Launch Instances" to initiate the process of launching a new EC2 instance.
Select AMI: Choose "Ubuntu 22.04" as the Amazon Machine Image (AMI) for your instance.
Choose Instance Type: Select "t2.medium" as the instance type in "Step 2."
Configure Instance: Configure instance details, storage, tags, and security group settings according to your requirements.
Review Settings: Review the settings you've configured.
Create or Select Key Pair: Create or select a key pair for secure access to the instance.
Launch Instance: Click "Launch" to launch the instance.
Connect to Instance: Once the instance is launched, connect to it via SSH using the associated key pair.

Associating an IAM Role with an EC2 Instance

Associating an IAM role with an EC2 instance allows the instance to access AWS services securely without the need to store long-term credentials like access keys. Here's how you can associate an IAM role with an EC2 instance:
1. Navigate to IAM Console: Access the AWS IAM (Identity and Access Management) console from the AWS Management Console.
2. Create IAM Role: Click on "Roles" in the IAM dashboard, then click "Create role" to initiate the role creation process.
3. Choose Service: Select "AWS service" as the trusted entity, and then choose "EC2" as the service that will use this role.
4. Add Permissions Policies: Attach necessary permissions policies to the role based on the permissions required by the EC2 instance. For example, you might attach policies like "AmazonS3FullAccess" or custom policies specific to your application needs.
5. Provide Role Name: Enter a descriptive name for the IAM role to easily identify its purpose, such as "tic-tac-toe."
6. Create Role: Once you've configured the role and attached the necessary policies, click on "Create role" to create the IAM role.
7. Assign Role to EC2 Instance: After creating the IAM role, go back to the EC2 dashboard. Select the instance you launched earlier and navigate to "Actions" -> "Security" -> "Modify IAM role."
8. Add Newly Created Role: In the "Modify IAM role" dialog, select the IAM role you created from the dropdown menu. This associates the IAM role with the EC2 instance.
9. Update IAM Role: Click on "Update IAM role" to apply the changes. The EC2 instance is now associated with the IAM role, allowing it to access AWS services securely using the permissions granted to the role.

Step 2: Adding a Self-Hosted Runner to EC2

Access GitHub Settings: Go to GitHub settings and navigate to "Actions" -> "Runners."
Add New Self-Hosted Runner: Click on "New self-hosted runner."
Select Linux and Architecture: Choose "Linux" as the operating system and "X64" as the architecture.
Connect to EC2 Instance: Use SSH to connect to your EC2 instance.
Create Directory: Create a new directory named "actions-runner" and navigate into it.
Download Runner: Download the GitHub Actions runner by running the provided curl command.
Validate Installation: Validate the hash installation to ensure the integrity of the downloaded file.
Extract Installer: Extract the downloaded installer.
Configure Runner: Run the configuration script (config.sh) to configure the runner, providing the GitHub repository URL and a token.
Start Runner: Start the runner by running the run.sh script.

Step 3: Installing Docker and Running SonarQube Container

Connect to EC2 Instance: Connect to your EC2 instance via SSH.
Update Package Repository: Update the package repository using sudo apt-get update.
Install Docker: Install Docker using sudo apt install docker.io.
Add User to Docker Group: Add the current user to the Docker group for running Docker commands without sudo.

Change Docker Socket Permissions: Change permissions of the Docker socket to allow access.

 sudo apt-get update
 sudo apt install docker.io -y
 sudo usermod -aG docker ubuntu
 newgrp docker
 sudo chmod 777 /var/run/docker.sock

Pull SonarQube Image: Pull the SonarQube Docker image from Docker Hub.
```
 docker run -d --name sonar -p 9000:9000 sonarqube:lts-community
```
Run SonarQube Container: Run the SonarQube container in detached mode, exposing port 9000.
Access SonarQube Dashboard: Access the SonarQube dashboard using the EC2 instance's public IP address and port 9000.
```
 <ec2-public-ip:9000>
```

Step 4A: Integrating SonarQube with GitHub Actions

Configure SonarQube Project: Configure a project in SonarQube and generate a token for integration with GitHub Actions.
```
 login admin
 password admin
```
Update your Sonarqube password & This is the Sonarqube dashboard

Step4B: Integrating SonarQube with GitHub Actions

Integrating SonarQube with GitHub Actions allows you to automatically analyze your code for quality and security as part of your continuous integration pipeline.

We already have Sonarqube up and running

On Sonarqube Dashboard click on Manually

Next, provide a name for your project and provide a Branch name and click on setup

On the next page click on With GitHub actions

This will Generate an overview of the Project and provide some instructions to integrate

Let’s Open your GitHub and select your Repository

Now go back to Your Sonarqube Dashboard

Copy SONAR_TOKEN and click on Generate Token

Now go back to GitHub and Paste the copied name for the secret and token

Name: SONAR_TOKEN

Secret: Paste Your Token and click on Add secret

Do same for SONAR_HOST_URL

Now create your Workflow for your Project. In my case, the Netflix project is built using React Js. That’s why I am selecting Other

Now it Generates and workflow for my Project

Go back to GitHub. click on Add file and then create a new file

Go back to the Sonarqube dashboard and copy the file name and content

Here file name (in my case only )
```
 sonar-project.properties
```
The content to add to the file is (copied from the above image)
```
 sonar.projectKey=tic-tac
```

.github/workflows/build.yml  #you can use any name iam using sonar.yml

Copy content and add it to the file

name: Build,Analyze,scan

on:
  push:
    branches:
      - main


jobs:
  build-analyze-scan:
    name: Build
    runs-on: [self-hosted]
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
        with:
          fetch-depth: 0  # Shallow clones should be disabled for a better relevancy of analysis

      - name: Build and analyze with SonarQube
        uses: sonarsource/sonarqube-scan-action@master
        env:
          SONAR_TOKEN: ${{ secrets.SONAR_TOKEN }}
          SONAR_HOST_URL: ${{ secrets.SONAR_HOST_URL }}Copy content and add it to the file

Now workflow is created.

Start again GitHub actions runner from instance

cd actions-runner
./run.sh

Click on Actions now

Go to the Sonarqube dashboard and click on projects and you can see the analysis

Step 6: EKS Provisioning

Clone Repository: Clone the TIC TAC TOE repository onto your EC2 instance.

 git clone https://github.com/VedThavkar/TIC-TAC-TOE
 cd TIC-TAC-TOE
 cd Eks-terraform

Navigate to EKS Terraform Files: Change directory to the EKS Terraform files.

This changes the directory to EKS terraform files
Update S3 Bucket in Backend File: Update the S3 bucket in the backend file for Terraform state storage.
Initialize Terraform: Initialize Terraform using terraform init.
```
 terraform init
```
Validate Configuration: Validate the configuration and syntax of Terraform files using terraform validate.
```
 terraform validate
```
Plan and Apply: Plan and apply the Terraform changes using terraform plan and terraform apply.
```
 terraform plan
 terraform apply
```
It will take 10 minutes to create the cluster

Node group ec2 instance

Now add the remaining steps

Next, install npm dependencies

      - name: NPM Install
        run: npm install # Add your specific npm install command

This step runs npm install to install Node.js dependencies. You can replace this with your specific npm install command.

      - name: Install Trivy
        run: |
          # Scanning files
          trivy fs . > trivyfs.txt

This step runs Trivy to scan files. It scans the current directory (denoted by .) and redirects the output to a file named trivyfs.txt.

Go to docker hub and click on your profile –> Account settings –> security –> New access token.

It asks for a name Provide a name and click on generate token.

Copy the token save it in a safe place, and close.

Now go to the github setting and add token in repository secrets.

      - name: Docker build and push
        run: |
          # Run commands to build and push Docker images
          docker build -t tic-tac-toe .
          docker tag tic-tac-toe vedantthavkar/tic-tac-toe:latest
          docker login -u ${{ secrets.DOCKERHUB_USERNAME }} -p ${{ secrets.DOCKERHUB_TOKEN }}
          docker push vedantthavkar/tic-tac-toe:latest
        env:
          DOCKER_CLI_ACI: 1

This step builds a Docker image with specific build arguments and tags it. It also logs in to Docker Hub using the provided credentials stored in secrets and pushes the Docker image.

Image is pushed to Dockerhub

Deploy

  deploy:
    needs: build-analyze-scan
    runs-on: self-hosted # Use your self-hosted runner label here

This section defines another job named “deploy.” It specifies that this job depends on the successful completion of the “build-analyze-scan” job. It also runs on a self-hosted runner. You should replace self-hosted with the label of your self-hosted runner.

    steps:
      - name: Pull the Docker image
        run: docker pull vedantthavkar/tic-tac-toe:latest

This step pulls the Docker image from Docker Hub, specified by sevenajay/tic-tac-toe:latest, which was built and pushed in the previous “build-analyze-scan” job

      - name: Trivy image scan
        run: trivy image svedantthavkar/tic-tac-toe:latest # Add Trivy scan command here

This step runs Trivy to scan the Docker image tagged as sevenajay/tic-tac-toe:latest. You should add the Trivy scan command here.

      - name: Run the container
        run: docker run -d --name ticgame -p 3000:3000 vedantthavkar/tic-tac-toe:latest

This step runs a Docker container named “ticgame” in detached mode (-d). It maps port 3000 on the host to port 3000 in the container. It uses the Docker image tagged as vedantthavkar/tic-tac-toe:latest.

Open Port in Security Group: Open port in the security group for the Node group instance.
Access TIC TAC TOE: Copy the external IP and paste it into the browser to access the TIC TAC TOE game.
```
 <ec2-ip:3000>
```
Deploy to EKS
```
       - name: Update kubeconfig
         run: aws eks --region <cluster-region> update-kubeconfig --name <cluster-name>
```
This step updates the kubeconfig to configure kubectl to work with an Amazon EKS cluster in the region with the name of your cluster.
```
       - name: Deploy to EKS
         run: kubectl apply -f deployment-service.yml
```
This step deploys Kubernetes resources defined in the deployment-service.yml file to the Amazon EKS cluster using kubectl apply.

SLACK

Go to your Slack channel, if you don’t have create one
1. click on your name
2. Select Settings and Administration
3. Click on Manage Apps
4. It will open a new tab, select build now
5. Select from scratch
6. Provide a name for the app and select workspace and create
7. Select Incoming webhooks
8. Set incoming webhooks to on
9. Click on Add New webhook to workspace
10. Select Your channel that created for notifications and allow
11. It will generate a webhook URL copy it
12. Comeback to github and add it the repository secrets.
  
  Add the below code to the workflow and commit and the workflow will start.
```
      - name: Send a Slack Notification
        if: always()
        uses: act10ns/slack@v1
        with:
          status: ${{ job.status }}
          steps: ${{ toJson(steps) }}
          channel: '#git'
        env:
          SLACK_WEBHOOK_URL: ${{ secrets.SLACK_WEBHOOK_URL }}
```

This step sends a Slack notification. It uses the act10ns/slack action and is configured to run “always,” which means it runs regardless of the job status. It sends the notification to the specified Slack channel using the webhook URL stored in secrets.
