Project :)

Implimented DevOps CI/CD pipeline using AWS Services

• CodeCommit
• CodeBuild
• CodeDeploy
• CodePipeline
• Identity and Access Management (IAM) for creating Service Role
• S3 for artifact storing
• EC2 for Deployment

Step 1: Simple Project Architecture

Step 2: Create a Repository in AWS CodeCommit

• After creating a repository on the next page you can see this warning.😟

• Go to IAM and create a User

• User can not get permission to access AWS CodeCommit, So first gives permissions in IAM. (IAM -> Users -> Security credentials -> HTTPS Git credentials for CodeCommit -> Generate)

• After this click on the Clone URL button.

• Also, Add permission to the User get to access this repo on Local. (IAM -> Users -> SelectUser -> Add permissions -> Attach policies directly -> 'AWSCodeCommitPowerUser')

• After performing some GitHubActions and pushing all files in CodeCommit.

• Master is default branch.

Step 3: Create Build Project

• GO to IAM and create Service Role for CodeBuild Service Role ("Access Service-Service") (IAM -> Create Role -> AWS service -> Use case -> Create)

• Create a buildSpec file.

   buildspec.yml

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 `data`
      - cp index.html /var/www/html/ 
  post_build:
    commands:
      - echo Configuring NGINX

artifacts:
  files:
    - '**/*'         

• Push this buildspec.yml file in CodeCommi.
• After you can Start to Build

Step 4: Build Artifact store in S3 Bucket

• In the CodeBuild console Click on Edit button -> Artifacts -> Type:"S3" -> put Uplode Locetion.

Step 5: CodeDeploy Part

• Create Application and Compute platform is EC2/On-premises
• Create Deployment group
• Create Service role (Give permissions -1.AmazonEC2FullAccess 2.AmazonEC2RoleforAWSCodeDeploy 3. AmazonS3FullAccess 4.AWSCodeDeployeFullAccess 5.AWSCodeDeployRole 6.AmazonEC2RoleforAWSCodeDeployLimitaccesstoS3)
• Deployment type - In-place
• Environment configuration - Amazon EC2 instances

Step 6: Create EC2 instance for deployment

• Click Launch Instances
• Ubuntu t2.micro
• Connect to the server and run this command to convert it into a Root user

sudo su

• First of all select instance -> Actios -> Security -> Modify IAM role -> select relevant role

• After running this script for setup deployingAgent on the EC2 instance

• Make sure your Rigeon and Script regions same.(6th line in this script)

#!/bin/bash 
# This installs the CodeDeploy agent and its prerequisites on Ubuntu 22.04.  
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

• Create appspec.yml for App configuretion

   appspec.yml

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    

• And Also create scripts folder

• In scripts folder create two files

  1. install_nginx.sh

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

  2. start_nginx.sh

  #!/bin/bash
  
  sudo service nginx start

• Push this file on CodeCommit

• After Deployment group is create then Create deployment.

Step 7: Create Pipeline

• Step 1: Choose pipeline setting -> PipelineName > Service role

• Step 2: Add source stage -> CodeCommit > repoName > branchName > Select CodePipeline periodically for changes(For autometion)

• Step 3: Add build stage -> BuildProvider > Region > ProjectName > Single build

• Step 4: Add deploy stage -> DeployProvider > Region > AppName > Deployment group

• Step 5: Review

  CodePipeline = Code->Commit->Build->Deploy

Step 8: Output.
