Congratulations on completing AWS CodeCommit and CodeBuild in your CI/CD pipeline journey! Now, let's delve into the next phase where we'll explore AWS CodeDeploy, CodePipeline, and S3 to enhance your pipeline even further.
Understanding CodeDeploy
Today, our focus shifts to AWS CodeDeploy, a powerful deployment service that automates application deployments across various environments, including Amazon EC2 instances, on-premises servers, Lambda functions, and ECS services. CodeDeploy enables seamless deployment of application content stored in Amazon S3 buckets, GitHub repositories, or Bitbucket repositories, without requiring any changes to your existing code.
Task 01: Exploring Appspec.yaml File for CodeDeploy
Read About Appspec.yaml File: Before diving into deployment, familiarize yourself with the Appspec.yaml file. The Appspec.yaml file is a YAML-formatted file that defines the deployment process for CodeDeploy. It specifies the deployment lifecycle events, such as application installation, pre-deployment hooks, and post-deployment hooks.
Deploy index.html File on EC2 Machine Using Nginx: To demonstrate the deployment process, let's deploy our index.html file onto an EC2 instance running an Nginx server. Ensure you have an EC2 instance set up and Nginx installed on it.
Setup CodeDeploy Agent: In order to deploy code on the EC2 instance, you need to set up the CodeDeploy agent. Log in to your EC2 instance and follow the instructions provided by AWS to install and configure the CodeDeploy agent.
Task 02: Completing the Deployment Process
Add Appspec.yaml File to CodeCommit Repository: Create an Appspec.yaml file that outlines the deployment process for CodeDeploy. Define the deployment lifecycle events, such as BeforeInstall, AfterInstall, and ApplicationStart, and specify the commands to be executed during each event.
Commit Changes to CodeCommit Repository: Once the Appspec.yaml file is ready, commit the changes to your CodeCommit repository. This ensures that CodeDeploy can access the necessary deployment configurations for the deployment process.
Trigger the Deployment: With the Appspec.yaml file in place, trigger the deployment process in CodeDeploy. Select the appropriate deployment group and specify the revision to be deployed. Monitor the deployment progress in the AWS Management Console or through CLI commands to ensure successful deployment of the index.html file onto the EC2 instance.
By completing these tasks, you'll have successfully integrated AWS CodeDeploy into your CI/CD pipeline, enabling automated deployments of your application content. Stay tuned for the next part of our journey, where we'll explore AWS CodePipeline and streamline the entire pipeline from code to deployment. Happy deploying! 🚀💻 #DevOps #AWS #CodeDeploy #CI_CD #Automation #LearningJourney
