Is it possible to run EKS Fargate on ARM?

As of now, it is not possible to run Amazon EKS (Elastic Kubernetes Service) Fargate on ARM architecture. While AWS Fargate does support ARM64 for Amazon ECS (Elastic Container Service), this capability has not yet been extended to EKS Fargate.

AWS Fargate does support ARM64 architecture for ECS workloads, allowing users to run Arm-based applications with cost savings and improved performance. However, for EKS, Fargate is currently limited to x86 architecture.

Regarding when ARM support for EKS Fargate will be available, there is no official announcement or timeline from AWS. Features and capabilities can change over time, so it's advisable to keep an eye on AWS announcements and documentation for any updates on this matter.

If running Kubernetes workloads on ARM is a requirement, you might consider using ECS with Fargate for ARM64 support, or explore other options within the AWS ecosystem that support ARM architecture for containerized workloads.
