• Connect to your EC2 instance and run the command “ssh-keygen -t rsa -b 4096” • Run the following command to display the contents on the public key file: “cat ~/.ssh/id_rsa.pub”. • Copy the output into your buffer. • On the console, navigate to the IAM service. Under security credentials for the user, select upload SSH public key. • Paste what you have in the space provided and upload. • After the upload, copy the SSH ID generated. • Go back to your EC2 instance. • In your local ~/.ssh directory, add the following lines to the config file there. If it’s not present, create one. • Give it read write permissions by running chmod 600 ~/.ssh/config o Host git-codecommit.*.amazonaws.com o User “your SSH ID” o IdentityFile ~/.ssh/id_rsa • Navigate to the CodeCommit service. • Select the repo you want to create and choose clone with SSH. • One the EC2 istance, run git clone “paste the URL” We now have to set up the Codebuild job: • Create an S3 called Application-xashy bucket to be used for storing the CodeBuild artifacts. • On the management console, search and navigate to the CodeBuild service. • Choose “Create project.” • Enter “Application-xashy” in the project name. • For Source provider, select “AWS CodeCommit” • Repository name is “Application-xashy”. • Choose “Use a buildspec file” in the build specifications. • Click on create project. • Now, select the code build project just created and choose “Start build.” • When the build is complete, examine the logs. Also, go to the S3 bucket you created and find the artifacts. We move to the CodeDeploy Job: • Create an IAM role that give EC2 access to S3. • Launch an EC2 instance and tag the instance with “Application = xashy”. • Attach the IAM role above to the instance. • Connect to that instance. • Run the following commands: o sudo yum update -y o sudo yum install -y ruby wget httpd o wget https://aws-codedeploy-us-east-2.s3.us-east-2.amazonaws.com/latest/install o chmod +x ./install o sudo ./install auto o sudo service codedeploy-agent status. • Go to IAM and select the create a role option. o Choose CodeDeploy for the use-case and select “CodeDeploy”. o Leave everything set to default. Name the role “Application-xashy” and create it. • On the console, navigate to the CodeDeploy service. • Click on create application. • For application name, enter “Application-xashy”. • Choose EC2/On-premises as the compute platform and click create. • Select “create deployment group”. • Name the deployment group as “Application-xashy” • In place of service role, give the IAM role you create above. • In the Environment configuration section, select Amazon EC2 instance, click on add tags. • Input the tags you set on the EC2 instance. • Un-check load balancer. • Create the deployment group. • Now, choose “Create deployment”. • Deployment group is Application-xashy. • Revision type is S3. • Copy and paste the URL. • Leave everything set to default and click on “create deployment”. We now configure CodePipeline: • Navigate to the CodePipeline service and choose create pipeline. • For pipeline name, enter Application-xashy • Choose new service role • Click advanced settings and use the codepipeline default s3 bucket. You also have the option to put in the URI of your S3 artifact.

Supply the repository and branch name. • Allow cloudwatch monitor and start the pipeline. • Leave output artifact format as default and click next. • Build provider is CodeBuild. • Give the build project name and choose single build. • Deploy provider is CodeDeploy. • Input the application name and deployment group name. • Choose next, review your settings, and create. Now on your EC2 instance, clone your CodeCommit repository, add the files, push them, and watch the pipeline.
