Creating Deployment Configurations for EKS with Amazon Q

Welcome to another installment of Q-Bits, our regular series showcasing cool ways Amazon employees are leveraging Amazon Q Developer. Today, we're exploring how Q Developer can assist with creating and optimizing EKS deployment configurations.

Amazon Q Developer streamlines EKS deployment workflows by providing intelligent assistance for Kubernetes configurations and best practices.

A Production Deployment Challenge

During my first project migrations to EKS, I needed to create deployment configurations for multiple microservices. With numerous configuration options and best practices to consider, so I had to read a huge number of wikis and api documents to understand and follow the best practices. I need to confess that it took a precious time to understand and write the files. Since 2024, Amazon Q Developer became my assistant for generating and validating deployment manifests, and I would like to share with you what I've learned and how to use Q Developer to create your Kubernetes deployment manifests.

Crafting Deployments with Q Developer

I will start by creating a basic deployment template. Instead of searching through documentation, I simply opened a new YAML file and asked Q Developer to help generate a sample deployment configuration.

Here is my prompt:

Amazon Q Developer promptly suggested a production-ready template:

Amazon Q Developer also explained me the key components making sure I have understanding about what I'm creating in my cluster.

Optimizing for Production

To ensure our deployment was production-ready, I highlighted the entire file and used "Amazon Q > Fix". Q Developer suggested several improvements:

1. Added comments to the main changes containing explanation about how to use the manifest

2. Added full ECR repository URL pattern

3. Implemented the imagePullPolicy

4. Improved probe configurations

As an improvement I can also request for Amazon Q Developer to implement a pod anti-affinity rule.

Troubleshooting Common Issues

Q Developer also helped identify potential issues before they occurred in production, such as:

Resource quota configurations
Network policy requirements
Service account permissions
Image pull policies

Improving an existing deployment

Q Developer will help to fix, improve, and adapt existing manifests. You can request Q Developer to:

Change the image to a new version
Add storage for stateful applications
Improve replicas distribution around the EKS cluster
Understand the current configuration

Conclusion

Amazon Q Developer has transformed the way I create and manage EKS deployments. It provides intelligent suggestions, validates configurations, and helps maintain best practices across our Kubernetes infrastructure. Whether you're new to EKS or an experienced DevOps engineer, Q Developer serves as an invaluable assistant in your deployment workflow.
