Day 52 - Your CI/CD pipeline on AWS - Part 3 🚀 ☁

🚀 Welcome to Day 52 of the #90DaysOfDevOpsChallenge! Today, we're diving deeper into our CI/CD pipeline on AWS with Part 3. Let's explore AWS CodeDeploy, CodePipeline, and S3!

☁️ CodeDeploy:

AWS CodeDeploy is a powerful deployment service that automates the process of deploying applications to various targets such as EC2 instances, Lambda functions, and ECS services.

Create a deployment and select the appropriate deployment group. Monitor the deployment process in the CodeDeploy console to ensure it completes successfully.

🚀 Deploying Your Website with AWS CodeDeploy and Nginx on EC2

Welcome to an exciting journey of deploying your website seamlessly using AWS CodeDeploy and Nginx on EC2 instances! 🌐

Let's embark on this journey step by step:

1. Setting Up Your CodeDeploy Application 🛠️

   • Navigate to the AWS CodeDeploy console and click on "Create Application".

     

   • Enter a name for your application, select the compute platform, and hit "Create application".

     

     

2. Establishing Connections with IAM 🔗

   • Head over to IAM and create a new role named 'code-deploy-service-role'.

     

     

   • Update the trust relationship to allow CodeDeploy access.

     

3. Creating a Deployment Group 🚀

   

   • In the CodeDeploy console, go to the Deployment Groups tab and click on "Create deployment group".

     

     

   • Specify a name and select the service role.

     

     

     

     

   • Choose deployment type as "In-place" and configure the environment for Amazon EC2 instances.

     

4. Installing the CodeDeploy Agent on EC2 💻

   • Run the provided script to install the CodeDeploy agent on your EC2 instance.

     ure, here's your script with some minor modifications and a few added comments for clarity:

       #!/bin/bash
       sudo apt-get update
       sudo apt-get install ruby-full ruby-webrick wget -y
       cd /tmp
       wget https://aws-codedeploy-us-east-1.s3.us-east-1.amazonaws.com/releases/codedeploy-agent_1.3.2-1902_all.deb
       mkdir codedeploy-agent_1.3.2-1902_ubuntu22
       dpkg-deb -R codedeploy-agent_1.3.2-1902_all.deb codedeploy-agent_1.3.2-1902_ubuntu22
       sed 's/Depends:.*/Depends: ruby3.0/' -i ./codedeploy-agent_1.3.2-1902_ubuntu22/DEBIAN/control
       dpkg-deb -b codedeploy-agent_1.3.2-1902_ubuntu22/
       sudo dpkg -i codedeploy-agent_1.3.2-1902_ubuntu22.deb
       systemctl list-units --type=service | grep codedeploy
       sudo service codedeploy-agent status
     

     

     

     

5. Preparing Your Website Files 📂

   • Create an index.html file containing your website content.

   • Craft an appspec.yaml file to instruct CodeDeploy on deployment actions.

   • Include scripts for installing and starting Nginx.

       version: 0.0
           os: linux
           files:
             - source: /
               destination: /var/www/html
           hooks:
             AfterInstall:
               - location: scripts/install_nginx.sh
                 timeout: 300
                 runas: root
             ApplicationStart:
               - location: scripts/start_nginx.sh
                 timeout: 300
                 runas: root
     

     Create start_nginx.sh in the scripts folder

       #!/bin/bash
       sudo service nginx start
     

     Create install_nginx.sh in the scripts folder

       #!/bin/bash
       sudo apt-get update
       sudo apt-get install nginx -y
     

6. Pushing Files to CodeCommit Repository 🚀

• Utilize Git commands to add and commit your files to the CodeCommit repository.

• Configuring CodeBuild 🛠️

  • Modify the buildspec.yml file to build the appspec.yaml file and package the artifact.

        version: 0.2
    
        phases:
          install:
            commands:
              - echo Installing NGINX
              - sudo apt-get update
              - sudo apt-get install nginx -y
          build:
            commands:
              - echo Build started on 'date'
              - cp index.html /var/www/html/
          post_build:
            commands:
              - echo Configuring NGINX
    
        artifacts:
            files:
              - '**/*'
    

    

  • Configure the Artifacts section to specify the path and packaging type.

    

    

    

• Initiating the Build Process 🚀

  • Start the build process in CodeBuild.

    

  • After completion, navigate to the S3 bucket and copy the S3 URI.

    

• Creating Deployment 🚀

  • In the CodeDeploy console, navigate to Deployments and click on "Create deployment".

    

  • Select Amazon S3 as the revision type and paste the S3 URL.

    

    

  • Initiate the deployment process.

    

    

• Ensuring EC2-S3 Communication 🔒

  • Create a new IAM role named 'EC2-S3-CodeDeploy' with necessary permissions.

  • Go to IAM service and create ‘EC2-S3-CodeDeploy’ with permissions.
    “AmazoneEC2FullAccess”, “AmazoneS3FullAccess”, “AWSCodeDeployFullAccess”.

    

    

    

    

  • Attach the role to your EC2 instance for accessing S3 and CodeDeploy.

      sudo service codedeploy-agent restart
      sudo service codedeploy-agent status
    

    

    

  • Restart the CodeDeploy agent for changes to take effect.

• Successful Deployment! ✅

  • Your deployment is now successful!

  • Access your website by browsing the public IP address of your EC2 instance.
