How to use AWS fargate with EKS

AWS provides two primary solutions for managing containerized applications: Amazon Elastic Kubernetes Service (EKS) and AWS Fargate. This post delves into the key differences and similarities between these powerful tools, helping you select the optimal solution for your specific workload requirements.

What is Amazon EKS?

Streamline your containerized application deployments with Amazon EKS, a fully managed Kubernetes service. EKS handles the complexities of Kubernetes cluster management, allowing you to focus on your applications. By automating the provisioning and management of control plane components, EKS ensures a reliable and scalable Kubernetes environment on AWS.

What is AWS Fargate?

Fargate is a serverless compute engine that seamlessly runs containers on AWS without requiring you to manage EC2 instances. By specifying task count and resource needs, you can delegate infrastructure management to AWS, allowing you to concentrate on application development and deployment.

Similarities and Differences

Both EKS and Fargate offer seamless container orchestration on AWS. As fully managed services, they eliminate the complexities of infrastructure management, allowing developers to focus on application development.

While both EKS and Fargate are powerful tools for deploying containerized applications, they offer distinct levels of infrastructure control. EKS provides granular access to the underlying EC2 instances and Kubernetes control plane, empowering users to fine-tune performance and security. Conversely, Fargate simplifies deployment by abstracting away infrastructure management, allowing developers to focus on application development and scaling.

While both EKS and Fargate are powerful tools for container orchestration, they differ significantly in their level of Kubernetes integration. EKS, as a fully managed Kubernetes service, offers a seamless and native Kubernetes experience, providing access to the full spectrum of Kubernetes features and capabilities. In contrast, Fargate, though a robust container engine, operates independently of Kubernetes, offering a more abstracted container execution environment.

Which solution is right for you?

The optimal choice between Amazon EKS and Fargate hinges on your specific use case and requirements. For organizations already leveraging Kubernetes and seeking a native experience with the full suite of Kubernetes features, EKS emerges as the clear frontrunner.

Seeking a more streamlined approach to container orchestration?

‍If you're new to Kubernetes or prefer a hands-off solution, AWS Fargate might be the ideal choice. By simply defining your task's resource needs, Fargate automates the underlying infrastructure, eliminating the complexity of managing servers.

To conclude, both AWS EKS and Fargate provide robust solutions for deploying containerized applications on AWS. The optimal choice hinges on your unique application needs and operational preferences. Either way, you can rely on a managed, scalable, and highly available platform to power your containerized workloads.

Seamlessly execute Fargate tasks within your EKS cluster using Amazon EKS Fargate profiles. This innovative feature empowers you to run pods on the serverless Fargate infrastructure, eliminating the need for EC2 instance management. By defining Fargate profiles, you can precisely control which pods utilize Fargate and which rely on EC2 instances, optimizing resource allocation and cost-efficiency.

Setting Up an Amazon EKS Cluster with a Fargate Profile

Simplify Kubernetes with AWS EKS Fargate. This comprehensive guide walks you through the steps of deploying containerized applications on a fully managed Kubernetes service without the hassle of managing infrastructure. Learn how to leverage the power of Fargate to effortlessly scale your applications.

Prerequisites:

1. An AWS account with appropriate permissions to create resources.
2. AWS CLI installed and configured with your AWS credentials.
3. Basic familiarity with Amazon EKS and Kubernetes concepts.

Step 1: Create an EKS Cluster:

1. Launch the AWS CLI and run the following command to create an EKS cluster:

aws eks create-cluster --name <cluster-name> --role-arn <eks-service-role-arn> --resources-vpc-config subnetIds=<subnet-ids>

Replace <cluster-name>with your desired cluster name, <eks-service-role-arn> with the ARN of the IAM role for EKS, and <subnet-ids> with your VPC’s subnet.

2. Wait for the cluster creation process to complete by monitoring the status with the aws eks describe-cluster command.

Step 2: Create an IAM Role for Fargate:

1. Create an IAM role specifically for Fargate by running the following command:

aws iam create-role --role-name <role-name> --assume-role-policy-document file://path/to/trust-policy.json

Replace <role-name> with a suitable name for the role, and provide the path to a JSON file containing the trust policy document.

2. Attach the required policies to the Fargate role. You can use the aws iam attach-role-policy command to attach policies such as AmazonEKSFargatePodExecutionRolePolicy.

Step 3: Create a Fargate Profile:

1. Create a Fargate profile for your EKS cluster using the following command:

aws eks create-fargate-profile --cluster-name <cluster-name> --fargate-profile-name <profile-name> --pod-execution-role-arn <fargate-execution-role-arn> --selectors namespace=<namespace>,<label-key>=<label-value>

Replace <cluster-name>with the name of your EKS cluster, <profile-name>with a desired name for the Fargate profile, <fargate-execution-role-arn>with the ARN of the Fargate execution role created in the previous step, and <namespace>, <label-key>, and <label-value>with the appropriate values for your pod selector.

2. Wait for the cluster creation process to complete by monitoring the status with the aws eks describe

Step 4: Launch Fargate Pods:

1. Create a Kubernetes deployment or pod specification YAML file that defines your application’s pods.
2. Apply the YAML file using kubectl apply -f <file-name>.yaml to launch your pods on Fargate.

Conclusion:

In this post, we explored the seamless integration of Amazon EKS and Fargate to streamline your Kubernetes operations. We delved into the step-by-step process of creating an EKS cluster, configuring IAM roles, establishing Fargate profiles, and deploying Fargate pods. By harnessing the power of EKS and Fargate, you can optimize your infrastructure management and accelerate application deployment and scaling.

To minimize costs, ensure all unused resources are promptly cleaned up after each experiment.
