Picture this: we are creating a YouTube-like platform where users can explore videos and channels. It’s a fantastic project, but managing the development workflow can be complex. That’s where GitLab CI/CD comes in, offering a straightforward and powerful solution to automate your work.

This step-by-step tutorial is for developers and devops enthusiasts looking to make their projects more efficient with CI/CD. By the end, you’ll know how to set up a robust CI/CD pipeline, including automated testing, code quality checks, and secure containerization. Let’s embark on this journey together and see how CI/CD can transform your development experience while building a React YouTube app clone.

Ready? Let’s simplify CI/CD and make your development life easier!

Step 1: Create an API key for Youtube.

Step 2: Create a Repository and push it to GitLab.

Step 3: Launch an Ec2 instance and run Sonarqube on it.

Step 4A: Create a `.gitlab-ci.yml` File.

Step 4B: Add the required variables for the project.

Step 5: Install Gitlab Runner on Ec2.

Step 6: Run the Application on the Docker container.

Step 7: Access the Application on Browser.

### Step 1: Create an API key from Rapid API

Open a new tab in the browser and search for [**rapidapi.com**](http://rapidapi.com/)

It will automatically provide your mail and select a mail to create an account

You will see the page like this and click on signup

Copy API Key as shown in screenshot and save it for further use at the docker stage.

docker build –build-arg REACT\_APP\_RAPID\_API\_KEY=<mark>&lt;API-KEY&gt;</mark> -t ${imageName} .

### Step 2: Create a Repository and push it to GitLab

Go to [GitLab.com](http://gitlab.com/) and login to your account

Click on New Project

![](https://cdn.hashnode.com/res/hashnode/image/upload/v1719234100945/74e47604-2b44-4d63-8e79-62772ca0a13b.avif align="center")

Click on Create Blank Project

![](https://cdn.hashnode.com/res/hashnode/image/upload/v1719234152767/d36594e2-71cf-4f2d-9def-7d2aedeb35e1.avif align="center")

Provide a name for the Project

Keep Visibility to the public

Uncheck the Readme and create the Project

![](https://cdn.hashnode.com/res/hashnode/image/upload/v1719234223172/30cfaf8a-10b9-44dc-84d6-e03e58b65580.avif align="center")

Use the below commands to push code to GitLab

```plaintext
cd existing_folder
git init --initial-branch=main
git remote add origin https://gitlab.com/sgawali/youtubev1.git
git add .
git commit -m "Initial commit"
git push --set-upstream origin main
```

Files pushed to GitLab

### Step 3: Launch an Ec2 instance and run Sonarqube on it

**Log into AWS Console:** Sign in to your AWS account.

**Launch an Instance:**

Choose **“EC2”** from services. Click “Launch Instance.”

**Choose an AMI:** Select an Ubuntu image.

**Choose an Instance Type:** Pick “t2.medium.”

**Key Pair:** Choose an existing key pair or create a new one.

**Configure Security Group:**

Create a new security group. Add rules for HTTP, and HTTPS, and open all ports for learning purposes. Add Storage: Allocate at least 10 GB of storage.

**Launch Instance:** Review and launch the instance.

Access Your Instance: Use SSH to connect to your instance with the private key.

Keep in mind, that opening all ports is not recommended for production environments; it’s just for educational purposes.

![](https://cdn.hashnode.com/res/hashnode/image/upload/v1719238375690/360def43-ade4-4dac-bf7a-aaf7fba37206.avif align="center")

**Connect to Your EC2 Instance and install docker:**

Run the below commands to install the docker

```bash
sudo apt-get update
sudo apt-get install docker.io -y
sudo usermod -aG docker $USER   #my case is ubuntu
newgrp docker
sudo chmod 777 /var/run/docker.sock
```

After the docker installation, we will create a Sonarqube container (Remember to add 9000 ports in the security group).

Run this command on your EC2 instance to create a SonarQube container:

```bash
docker run -d --name sonar -p 9000:9000 sonarqube:lts-community
```

Now copy the IP address of the ec2 instance

```plaintext
<ec2-public-ip:9000>
```

Enter username and password, click on login and change password

```plaintext
username admin
password admin
```
