Welcome to the world of AWS CodeDeploy. Ahead, you’ll walk through the initial steps to use this service effectively. We’ll start with creating an AWS account and then move on to uploading your source code to an AWS S3 Storage Bucket.
If you haven’t already, the first thing you need to do is create an AWS account. Click the “Create an AWS Account” button to navigate to the AWS homepage. Follow the instructions to set up your account.
Once your account is created, sign in to the AWS Management Console. This is the central hub where you’ll manage all your AWS services.
Before using CodeDeploy, upload your application’s source code to an Amazon S3 storage bucket. To do this:
- Create a new S3 bucket in your AWS Management Console
- Click on the bucket name and then the Upload button
- Choose your source code files and click on Start Upload
Once the files have successfully uploaded, you can configure CodeDeploy to automate your application’s deployment process.
AWS CodeDeploy offers two main deployment types: in-place and blue/green deployments. In-place deployments apply updates directly to the running instances, while blue/green deployments create new instances with the updated code.
Each deployment type has unique benefits and use cases. In-place deployments are more straightforward, while blue/green deployments provide added benefits such as reduced downtime and easier rollback.
As an AWS expert, you must consider your specific requirements and infrastructure before choosing a deployment type. Here, we will explore blue/green deployments in detail.
A blue/green deployment ensures your application remains available during an update. It creates a new environment, often called the “green” environment, which runs the updated code.
Your existing environment, the “blue” one, continues to serve your users until the green environment is fully set up and tested. Once the green environment is ready, traffic gradually shifts, with minimal disruption and downtime.
This approach offers several advantages, such as:
- Decreased downtime
- Easier rollback
- Opportunity to test new code in a controlled environment
AWS CodeDeploy facilitates blue/green deployments on AWS Lambda and Amazon ECS compute platforms. With AWS Lambda, the service creates updated lambda function versions and shifts the traffic between the old and the new version.
On the Amazon ECS platform, CodeDeploy creates a replacement task set with the updated containers. Then, it reroutes the traffic between the original and the new task set using Elastic Load Balancing (ELB).
Here’s a brief outline of the process:
- Create an AppSpec file that defines your application settings and resources
- Prepare your application for deployment, ensuring your updated code is in a repository supported by CodeDeploy
- Create a CodeDeploy application and deployment group specifying the compute platform, deployment type, and other configuration files
- Use the AWS Management Console, AWS CLI, or AWS SDK to trigger deployment and monitor its progress
AWS CodeDeploy is built on three primary components: Application, Deployment Group, and Deployment. Understanding each component’s responsibilities will give you a solid foundation for effective deployment processes.
- Application: A container for storage and deployment settings.
- Deployment Group: A group of instances and other resources for deployment, including Amazon EC2 instances, Auto Scaling groups, and on-premises instances.
- Deployment: An actual deployment process which encapsulates files and settings for your environment.
AppSpec files play a crucial role in controlling the deployment process. These YAML-formatted files consist of two primary sections – ‘files’ and ‘hooks,’ which determine your application deployments and how lifecycle events are managed.
Specifies the source and destination of your application files, including your source code and any supporting files.
Defines the scripts to be executed at specific lifecycle events before installation, installation, or the application start.
