A few days ago, Amazon announced the general availability of the Windows Container support on  Amazon Elastic Kubernetes Service (EKS). The company announced a preview of the Windows Container support in March this year and also invited customers to try it out and provide their feedback.

With the Windows Container Support, development teams can now deploy applications designed to run on Windows Servers, on Kubernetes alongside Linux applications. It will also bring in more consistency in system logging, performance monitoring, and code deployment pipelines.

“We are proud to be the first Cloud provider to have General Availability of Windows Containers on Kubernetes and look forward to customers unlocking the business benefits of Kubernetes for both their Windows and Linux workloads,” the official post mentions.

A few considerations before deploying the Worker nodes include:

  • Windows workloads are supported with Amazon EKS clusters running Kubernetes version 1.14 or later.
  • Amazon EC2 instance types C3, C4, D2, I2, M4 (excluding m4.16xlarge), and R3 instances are not supported for Windows workloads.
  • Host networking mode is not supported for Windows workloads.
  • Amazon EKS clusters must contain 1 or more Linux worker nodes to run core system pods that only run on Linux, such as coredns and the VPC resource controller.
  • The kubelet and kube-proxy event logs are redirected to the Amazon EKS Windows Event Log and are set to a 200 MB limit.

In a demonstration, Martin Beeby, a principal evangelist for Amazon Web Services has created a new Amazon Elastic Kubernetes Service cluster, which works with any cluster that is using Kubernetes version 1.14 and above. He has also added some new Windows nodes and deploys a Windows application.

For a complete demonstration and to know more about the Amazon EKS Windows Container Support, read AWS’ official blog post.
