Upgraded cluster add-ons

As part of our regular upgrade cycle, the following Kubernetes cluster components have been updated and are gradually rolling out to all our managed clusters. One of the main updates included in this cycle is the move to TSDB as Grafana Loki’s index backend, which will improve query performance and resource utilization.

Upgraded Teleport to version 15.0.1

We’ve upgraded all Teleport clusters from version 14.0.1 to 15.0.1. Teleport is a tool we mostly use internally to provide secure and auditted access to (EC2) instances, Kubernetes clusters and several dashboards. The nodes will gradually be upgraded to the new version when new instances are launched.

Karpenter now deployed by default and migrated system pool

In September last year we announced the addition of Karpenter as experimental feature. Since then we have been making improvements to our implementation and gradually used some pilots internally and with some customers. We are happy to announce that Karpenter is now deployed by default (via AWS Fargate) on all our EKS clusters and we’ve migrated the system NodePool to use it instead of the standard Cluster Autoscaler.

Removed Calico as NetworkPolicies engine - this functionality has merged with the AWS VPC CNI

Historically we’ve been using Calico as controller to provide NetworkPolicies support. This was offered as an optional feature only, considering the resource (and thus possible cost) impact of running this component. As announced in our K8s 1.27 upgrade post, the latest version of the AWS VPC CNI, responsible for providing cluster networking, now has native support for NetworkPolicies built-in.

Support for GPU node pools on AWS (EKS)

We’re adding support for GPU node pools in EKS. GPU nodes are great for compute-intensive workloads such as graphics and visualization workloads, or machine-learning processes. AWS uses the NVIDIA device plugin to make the GPU capacity of a node available to Kubernetes workloads.

Disable kubernetes-dashboard by default

In an effort to further reduce the footprint of the reference solution we are no longer going to deploy the kubernetes-dashboard* by default. The Skyscrapers team is using k9s as a tool to manage our clusters and we think its a worhty replacement. This tool can just run in your terminal and doesn’t require any deployments on the K8s side. If you have this workload enabled today we will reach out to you to check if you are using this and take action based on your input.
