Today, Amazon announced a managed Kubernetes service called Elastic Container Service for Kubernetes (EKS). This means that all three major cloud providers—AWS, Azure, and GCP—now offer managed Kubernetes services. This is great news for Kubernetes users. Even though users always have the option to stand up their own Kubernetes clusters, and new tools like Rancher Kubernetes Engine (RKE) make that process even easier, cloud-managed Kubernetes installations should be the best choice for the majority of Kubernetes users.

One of the hallmark features of Rancher 2.0 is its ability to consume Kubernetes clusters from anywhere. In this post, I’m going to walk you through using the popular kops tool to create and manage Kubernetes clusters on AWS and then bring them under Rancher 2.0 management. This walkthrough will help you create a non-HA Kubernetes cluster, though kops does support HA configurations. With this new cluster, we will run the Rancher 2.

In my prior posts, I’ve written about how to ensure a highly resilient workloads using Docker, Rancher, and various open source tools. For this post, I will build on this prior knowledge, and to setup an AWS infrastructure for Rancher with some commonly used tools. If you check out the repository here, you should be able to follow along and setup the same infrastructure. The final output of our AWS infrastructure will look like the following picture: In case you missed the prior posts, they’re available on the Rancher blog and cover some reliability talking points.

Rancher ships with two types of catalog items to deploy applications; Rancher certified catalog and community catalog, which enable the community to contribute to the reusable pre-built application stack templates. One of the recent interesting community catalog templates is the external load balancer for AWS Classic Elastic Load Balancer, which keeps an existing Load balancer updated with the EC2 instances on which Rancher services that have one or more exposed ports and specific label.

Containers and orchestration frameworks like Rancher will soon allow every organization to have access to efficient cluster management. This brave new world frees operations from managing application configuration and allows development to focus on writing code; containers abstract complex dependency requirements, which enables ops to deploy immutable containerized applications and allows devs a consistent runtime for their code. If the benefits are so clear, then why do companies with existing infrastructure practices not switch?
