i tried to setup AWS CodePipeline and AWS CodeDeploy to deploy application on Amazon EC2 using github as a source

• Rapidly release new features.
• Update AWS Lambda function versions.
• Avoid downtime during application deployment.
• Handle the complexity of updating your applications, without many of the risks associated with error-prone manual deployments.

Hands-On:

Setup IAM Role

Create a role for CodeDeploy + EC2

• ROLE 1:
  • Select Your Use Case: EC2

• • Permissions Policies: AmazonEC2RoleForAWSCodeDeploy
  • Role Name: EC2_CodeDeploy_DevIO,AmazonS3FullAccess

• ROLE 2:
  • Select Your Use Case: CodeDeploy

• • Permissions Policies: AWSCodeDeployRole
  • Role Name : CodeDeploy_DevIO
  • 

 

Setup EC2 as deployment server

 

Choose AMI: Amazon Linux 2

Instance Type : t2.micro

no. of Instances: 1

Security groups: enable port port 22 for ssh and HTTP 80 for application

User Data: add below script in user data to add the required

change the link according to your region in line-6: bucket-name is the name of the Amazon S3 bucket that contains the CodeDeploy Resource Kit files for your region. region-identifier is the identifier for your region.to find bucket name and region Click here

#!/bin/bash
sudo yum -y update
sudo yum -y install ruby
sudo yum -y install wget
cd /home/ec2-user
wget https://bucket-name.s3.region-identifier.amazonaws.com/latest/install
sudo chmod +x ./install
sudo ./install auto
sudo yum install -y python-pip
sudo pip install awscli

ADD Tag: Name: DevelopersIOEC2Instance

 

lauch the instance without keypair

Setup application and deploymentGroup

1. Create application
   1. Application Name : DevelopersIODemo
   2. Compute Platform : EC2/OnPremises
   3. 
2. Create Application
3. Create Deployment Group
   1. Enter a deployment group name: DevelopersIoDmoDeploymentGroup
   2. Service role ARN: CodeDeploy_DevIO
   3. Deployment type: In-place
   4. Deployment configuration: CodeDeployDefault.AllAtOnce
   5. Environment configuration: Amazon EC2 instances
      1. Name: DevelopersIOEC2Instance

Setup github with Sample App:

bellow code will download sample app from s3

mkdir codedeploy-sample
cd codedeploy-sample
curl -O http://s3.amazonaws.com/aws-codedeploy-us-east-1/samples/latest/SampleApp_Linux.zip
unzip SampleApp_Linux.zip
rm SampleApp_Linux.zip

this command will upload the sample app in github

git init
git add .
git commit -m "first commit"
git remote add origin git@github.com:YOUR_USERNAME/YOUR_REPOSITORY.git
git push -u origin master

 

Setup CodePipeline:

1. choose codepipeline from developer tool in aws services
2. create pipeline
3. choose pipeline setting:
   1. pipeline name: DevelopersIO Pipeline
   2. Service role : create new service role
   3. next

Add source stage:

• source provider: Github(version 2)
• connection: connect to github // add username and password of your github account
• repository name: aws_codedeploy_using_Github //add repository name where you pushed sample_app as it consist of settings
• branch name: main //select the working branch where you will push product for deployment
• select start the pipeline on source code change
• output artifact format: codepipelinedefault
• click next -> create

 

finally:

we have successfully created a cicd pipeline now every time we push a new code into github this pipeline will automatically deploy the application in Amazon EC2
