Release Notes

EKS 1.25+ cluster-autoscaler

As of this release when installing the cluster-autoscaler on EKS 1.25+ clusters, the helm chart version 9.25.0 is used for compatibility reasons. This is because Kubernetes 1.25 has deprecated the PodDisruptionBudget policy/v1beta1 API version in favor of policy/v1 and this updated cluster-autoscaler version supports that change. This updated cluster-autoscaler chart requires an updated IAM role/policy for the cluster-autoscaler role to properly function.

If you used viya4-iac-aws:5.6.0 or newer to create your EKS infrastructure, code changes have already been made so that this updated role & policy are created. However, if you have used an older version of viya4-iac-aws to create your EKS 1.25+ cluster we have outlined steps to update the role & policy in the Troubleshooting documentation

Kustomize

Installing kustomize is no longer a requirement for this project. We will now be consuming the kustomize binary that is already included within the sas-orchestration image. The image that is pulled down (sourced from sas-bases/.orchestration/images.yaml) should always have a version of kustomize packaged with it that is compatible with the cadence that is going to be deployed.
