Step 1: Launch EC2 (Ubuntu 22.04):

• Provision an EC2 instance on AWS with Ubuntu 22.04.
• Connect to the instance using SSH.

Step 2: Clone the Code:

• Update all the packages and then clone the code.

• Clone your application's code repository onto the EC2 instance:

  git clone https://github.com/N4si/DevSecOps-Project.git

Step 3: Install Docker and Run the App Using a Container:

• Set up Docker on the EC2 instance:

  sudo apt-get update
  sudo apt-get install docker.io -y
  sudo usermod -aG docker $USER  # Replace with your system's username, e.g., 'ubuntu'
  newgrp docker
  sudo chmod 777 /var/run/docker.sock

• Build and run your application using Docker containers:

  docker build -t netflix .
  docker run -d --name netflix -p 8081:80 netflix:latest
  
  #to delete
  docker stop <containerid>
  docker rmi -f netflix

It will show an error cause you need API key

Step 4: Get the API Key:

• Open a web browser and navigate to TMDB (The Movie Database) website.
• Click on "Login" and create an account.
• Once logged in, go to your profile and select "Settings."
• Click on "API" from the left-side panel.
• Create a new API key by clicking "Create" and accepting the terms and conditions.
• Provide the required basic details and click "Submit."
• You will receive your TMDB API key.

Now recreate the Docker image with your api key:

docker build --build-arg TMDB_V3_API_KEY=<your-api-key> -t netflix .

Phase 2: Security

1. Install SonarQube and Trivy:

   • Install SonarQube and Trivy on the EC2 instance to scan for vulnerabilities.

     sonarqube

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

     To access:

     publicIP:9000 (by default username & password is admin)

     To install Trivy:

     sudo apt-get install wget apt-transport-https gnupg lsb-release
     wget -qO - https://aquasecurity.github.io/trivy-repo/deb/public.key | sudo apt-key add -
     echo deb https://aquasecurity.github.io/trivy-repo/deb $(lsb_release -sc) main | sudo tee -a /etc/apt/sources.list.d/trivy.list
     sudo apt-get update
     sudo apt-get install trivy        
     

     to scan image using trivy

     trivy image <imageid>
     

2. Integrate SonarQube and Configure:

   • Integrate SonarQube with your CI/CD pipeline.
   • Configure SonarQube to analyze code for quality and security issues.

Phase 3: CI/CD Setup

1. Install Jenkins for Automation:

   • Install Jenkins on the EC2 instance to automate deployment: Install Java

   sudo apt update
   sudo apt install fontconfig openjdk-17-jre
   java -version
   openjdk version "17.0.8" 2023-07-18
   OpenJDK Runtime Environment (build 17.0.8+7-Debian-1deb12u1)
   OpenJDK 64-Bit Server VM (build 17.0.8+7-Debian-1deb12u1, mixed mode, sharing)
   
   #jenkins
   sudo wget -O /usr/share/keyrings/jenkins-keyring.asc \
   https://pkg.jenkins.io/debian-stable/jenkins.io-2023.key
   echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] \
   https://pkg.jenkins.io/debian-stable binary/ | sudo tee \
   /etc/apt/sources.list.d/jenkins.list > /dev/null
   sudo apt-get update
   sudo apt-get install jenkins
   sudo systemctl start jenkins
   sudo systemctl enable jenkins

   • Access Jenkins in a web browser using the public IP of your EC2 instance.

     publicIp:8080

2. Install Necessary Plugins in Jenkins:

Goto Manage Jenkins →Plugins → Available Plugins →

Install below plugins

1 Eclipse Temurin Installer (Install without restart)

2 SonarQube Scanner (Install without restart)

3 NodeJs Plugin (Install Without restart)

4 Email Extension Plugin

Goto Manage Jenkins → Tools → Install JDK(17) and NodeJs(16)→ Click on Apply and Save

Create the token

Goto Jenkins Dashboard → Manage Jenkins → Credentials → Add Secret Text. It should look like this

After adding sonar token

Click on Apply and Save

The Configure System option is used in Jenkins to configure different server

Global Tool Configuration is used to configure different tools that we install using Plugins

We will install a sonar scanner in the tools.

Create a Jenkins webhook

1. Configure CI/CD Pipeline in Jenkins:

• Create a CI/CD pipeline in Jenkins to automate your application deployment.

pipeline {
    agent any
    tools {
        jdk 'jdk17'
        nodejs 'node16'
    }
    environment {
        SCANNER_HOME = tool 'sonar-scanner'
    }
    stages {
        stage('clean workspace') {
            steps {
                cleanWs()
            }
        }
        stage('Checkout from Git') {
            steps {
                git branch: 'main', url: 'https://github.com/N4si/DevSecOps-Project.git'
            }
        }
        stage("Sonarqube Analysis") {
            steps {
                withSonarQubeEnv('sonar-server') {
                    sh '''$SCANNER_HOME/bin/sonar-scanner -Dsonar.projectName=Netflix \
                    -Dsonar.projectKey=Netflix'''
                }
            }
        }
        stage("quality gate") {
            steps {
                script {
                    waitForQualityGate abortPipeline: false, credentialsId: 'Sonar-token'
                }
            }
        }
        stage('Install Dependencies') {
            steps {
                sh "npm install"
            }
        }
    }
}

Certainly, here are the instructions without step numbers:

            }
        }
    }
}


If you get docker login failed errorr

sudo su
sudo usermod -aG docker jenkins
sudo systemctl restart jenkins

Phase 4: Monitoring

1. Install Prometheus and Grafana:

   Set up Prometheus and Grafana to monitor your application.

   Installing Prometheus:

   First, create a dedicated Linux user for Prometheus and download Prometheus:

   sudo useradd --system --no-create-home --shell /bin/false prometheus
   wget https://github.com/prometheus/prometheus/releases/download/v2.47.1/prometheus-2.47.1.linux-amd64.tar.gz

   Extract Prometheus files, move them, and create directories:

   tar -xvf prometheus-2.47.1.linux-amd64.tar.gz
   cd prometheus-2.47.1.linux-amd64/
   sudo mkdir -p /data /etc/prometheus
   sudo mv prometheus promtool /usr/local/bin/
   sudo mv consoles/ console_libraries/ /etc/prometheus/
   sudo mv prometheus.yml /etc/prometheus/prometheus.yml

   Set ownership for directories:

   sudo chown -R prometheus:prometheus /etc/prometheus/ /data/

   Create a systemd unit configuration file for Prometheus:

   sudo nano /etc/systemd/system/prometheus.service

   Add the following content to the prometheus.service file:

   [Unit]
   Description=Prometheus
   Wants=network-online.target
   After=network-online.target
   
   StartLimitIntervalSec=500
   StartLimitBurst=5
   
   [Service]
   User=prometheus
   Group=prometheus
   Type=simple
   Restart=on-failure
   RestartSec=5s
   ExecStart=/usr/local/bin/prometheus \
     --config.file=/etc/prometheus/prometheus.yml \
     --storage.tsdb.path=/data \
     --web.console.templates=/etc/prometheus/consoles \
     --web.console.libraries=/etc/prometheus/console_libraries \
     --web.listen-address=0.0.0.0:9090 \
     --web.enable-lifecycle
   
   [Install]
   WantedBy=multi-user.target
   

   Here's a brief explanation of the key parts in this prometheus.service file:

   • User and Group specify the Linux user and group under which Prometheus will run.

   • ExecStart is where you specify the Prometheus binary path, the location of the configuration file (prometheus.yml), the storage directory, and other settings.

   • web.listen-address configures Prometheus to listen on all network interfaces on port 9090.

   • web.enable-lifecycle allows for management of Prometheus through API calls.

   Enable and start Prometheus:

   sudo systemctl enable prometheus
   sudo systemctl start prometheus

   Verify Prometheus's status:

   sudo systemctl status prometheus

   You can access Prometheus in a web browser using your server's IP and port 9090:

   http://<your-server-ip>:9090

   Installing Node Exporter:

   Create a system user for Node Exporter and download Node Exporter:

   sudo useradd --system --no-create-home --shell /bin/false node_exporter
   wget https://github.com/prometheus/node_exporter/releases/download/v1.6.1/node_exporter-1.6.1.linux-amd64.tar.gz

   Extract Node Exporter files, move the binary, and clean up:

   tar -xvf node_exporter-1.6.1.linux-amd64.tar.gz
   sudo mv node_exporter-1.6.1.linux-amd64/node_exporter /usr/local/bin/
   rm -rf node_exporter*

   Create a systemd unit configuration file for Node Exporter:

   sudo nano /etc/systemd/system/node_exporter.service

   Add the following content to the node_exporter.service file:

   [Unit]
   Description=Node Exporter
   Wants=network-online.target
   After=network-online.target
   
   StartLimitIntervalSec=500
   StartLimitBurst=5
   
   [Service]
   User=node_exporter
   Group=node_exporter
   Type=simple
   Restart=on-failure
   RestartSec=5s
   ExecStart=/usr/local/bin/node_exporter --collector.logind
   
   [Install]
   WantedBy=multi-user.target
   

   Replace --collector.logind with any additional flags as needed.

   Enable and start Node Exporter:

   sudo systemctl enable node_exporter
   sudo systemctl start node_exporter

   Verify the Node Exporter's status:

   sudo systemctl status node_exporter

   You can access Node Exporter metrics in Prometheus.

2. Configure Prometheus Plugin Integration:

   Integrate Jenkins with Prometheus to monitor the CI/CD pipeline.

   Prometheus Configuration:

   To configure Prometheus to scrape metrics from Node Exporter and Jenkins, you need to modify the prometheus.yml file. Here is an example prometheus.yml configuration for your setup:

   global:
     scrape_interval: 15s
   
   scrape_configs:
     - job_name: 'node_exporter'
       static_configs:
         - targets: ['localhost:9100']
   
     - job_name: 'jenkins'
       metrics_path: '/prometheus'
       static_configs:
         - targets: ['<your-jenkins-ip>:<your-jenkins-port>']

   Make sure to replace <your-jenkins-ip> and <your-jenkins-port> with the appropriate values for your Jenkins setup.

   Check the validity of the configuration file:

   promtool check config /etc/prometheus/prometheus.yml

   Reload the Prometheus configuration without restarting:

   curl -X POST http://localhost:9090/-/reload

   You can access Prometheus targets at:

   http://<your-prometheus-ip>:9090/targets

####Grafana

Install Grafana on Ubuntu 22.04 and Set it up to Work with Prometheus

Step 1: Install Dependencies:

First, ensure that all necessary dependencies are installed:

sudo apt-get update
sudo apt-get install -y apt-transport-https software-properties-common

Step 2: Add the GPG Key:

Add the GPG key for Grafana:

wget -q -O - https://packages.grafana.com/gpg.key | sudo apt-key add -

Step 3: Add Grafana Repository:

Add the repository for Grafana stable releases:

echo "deb https://packages.grafana.com/oss/deb stable main" | sudo tee -a /etc/apt/sources.list.d/grafana.list

Step 4: Update and Install Grafana:

Update the package list and install Grafana:

sudo apt-get update
sudo apt-get -y install grafana

Step 5: Enable and Start Grafana Service:

To automatically start Grafana after a reboot, enable the service:

sudo systemctl enable grafana-server

Then, start Grafana:

sudo systemctl start grafana-server

Step 6: Check Grafana Status:

Verify the status of the Grafana service to ensure it's running correctly:

sudo systemctl status grafana-server

Step 7: Access Grafana Web Interface:

Open a web browser and navigate to Grafana using your server's IP address. The default port for Grafana is 3000. For example:

http://<your-server-ip>:3000

You'll be prompted to log in to Grafana. The default username is "admin," and the default password is also "admin."

Step 8: Change the Default Password:

When you log in for the first time, Grafana will prompt you to change the default password for security reasons. Follow the prompts to set a new password.

Step 9: Add Prometheus Data Source:

To visualize metrics, you need to add a data source. Follow these steps:

• Click on the gear icon (⚙️) in the left sidebar to open the "Configuration" menu.

• Select "Data Sources."

• Click on the "Add data source" button.

• Choose "Prometheus" as the data source type.

• In the "HTTP" section:

  • Set the "URL" to http://localhost:9090 (assuming Prometheus is running on the same server).
  • Click the "Save & Test" button to ensure the data source is working.

Step 10: Import a Dashboard:

To make it easier to view metrics, you can import a pre-configured dashboard. Follow these steps:

• Click on the "+" (plus) icon in the left sidebar to open the "Create" menu.

• Select "Dashboard."

• Click on the "Import" dashboard option.

• Enter the dashboard code you want to import (e.g., code 1860).

• Click the "Load" button.

• Select the data source you added (Prometheus) from the dropdown.

• Click on the "Import" button.

You should now have a Grafana dashboard set up to visualize metrics from Prometheus.

Grafana is a powerful tool for creating visualizations and dashboards, and you can further customize it to suit your specific monitoring needs.

That's it! You've successfully installed and set up Grafana to work with Prometheus for monitoring and visualization.

2. Configure Prometheus Plugin Integration:
   • Integrate Jenkins with Prometheus to monitor the CI/CD pipeline.

Phase 5: Notification

1. Implement Notification Services:
   • Set up email notifications in Jenkins or other notification mechanisms.

In this phase, you'll set up a Kubernetes cluster with node groups. This will provide a scalable environment to deploy and manage your applications.

Prometheus is a powerful monitoring and alerting toolkit, and you'll use it to monitor your Kubernetes cluster. Additionally, you'll install the node exporter using Helm to collect metrics from your cluster nodes.

To begin monitoring your Kubernetes cluster, you'll install the Prometheus Node Exporter. This component allows you to collect system-level metrics from your cluster nodes. Here are the steps to install the Node Exporter using Helm:

1. Add the Prometheus Community Helm repository:

   helm repo add prometheus-community https://prometheus-community.github.io/helm-charts

2. Create a Kubernetes namespace for the Node Exporter:

   kubectl create namespace prometheus-node-exporter

3. Install the Node Exporter using Helm:

   helm install prometheus-node-exporter prometheus-community/prometheus-node-exporter --namespace prometheus-node-exporter

Add a Job to Scrape Metrics on nodeip:9001/metrics in prometheus.yml:

Update your Prometheus configuration (prometheus.yml) to add a new job for scraping metrics from nodeip:9001/metrics. You can do this by adding the following configuration to your prometheus.yml file:

  - job_name: 'Netflix'
    metrics_path: '/metrics'
    static_configs:
      - targets: ['node1Ip:9100']

Replace 'your-job-name' with a descriptive name for your job. The static_configs section specifies the targets to scrape metrics from, and in this case, it's set to nodeip:9001.

Don't forget to reload or restart Prometheus to apply these changes to your configuration.

To deploy an application with ArgoCD, you can follow these steps, which I'll outline in Markdown format:

1. Install ArgoCD:

   You can install ArgoCD on your Kubernetes cluster by following the instructions provided in the EKS Workshop documentation.

2. Set Your GitHub Repository as a Source:

   After installing ArgoCD, you need to set up your GitHub repository as a source for your application deployment. This typically involves configuring the connection to your repository and defining the source for your ArgoCD application. The specific steps will depend on your setup and requirements.

3. Create an ArgoCD Application:

   • name: Set the name for your application.
   • destination: Define the destination where your application should be deployed.
   • project: Specify the project the application belongs to.
   • source: Set the source of your application, including the GitHub repository URL, revision, and the path to the application within the repository.
   • syncPolicy: Configure the sync policy, including automatic syncing, pruning, and self-healing.

4. Access your Application

   • To Access the app make sure port 30007 is open in your security group and then open a new tab paste your NodeIP:30007, your app should be running.

Phase 7: Cleanup

1. Cleanup AWS EC2 Instances:
   • Terminate AWS EC2 instances that are no longer needed.
