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.

In order to improve our services we changed the way the Kubernetes nodepools are structured. Previously there was a default nodepool that had a mix of both Kubernetes add-ons and application deployments. This made things more complex than it needed to be. Therefore we created a dedicated system
nodepool where all add-ons are scheduled on. During this change we also took a closer look at the requested resources for all add-ons and made adjustments where needed. For most of our customer environment we’ve been able to reduce the cluster size with at least 1 equivalent node. A handful are break-even for now, but we have further optimizations planned as follow-ups.

During the past days we’ve had multiple customer reports that launching new Pods got stuck with the ContainerCreating
status, mostly affecting CronJobs. Even if you were not directly affected, you might have noticed the messages in your channels that we’ve been rolling out a lot of node updates without prior notice. This small post mortem will explain the reason, what steps we took to mitigate, and what we should have done better.

Most of our EKS clusters leverage Spot instances as a cost-efficient way to provide compute nodes. Historically we’ve been defaulting to the “lowest price” allocation strategy to maximize possible cost savings. However this can lead to quite some more interuptions than we want to tolerate and often a big inbalance between AZ spread if price pressure increases. Therefore we’ve updated our default to use a “capacity optimized” strategy instead for increased stability with (possibly) a marginal higher cost.
