Announcements

  • CIS Kubernetes V1.27 Benchmark is published which covers AKS 1.21.x through AKS 1.27.x.
  • Kubernetes 1.25 is being deprecated on January 14, 2024 and support will transition to our platform support policy. Please upgrade to Kubernetes version 1.26 or above.
  • Starting January 2024, due to Gatekeeper Upstream removing validation for constraint template contents at create/update time, the Azure Policy Add-On will now no longer support the validation for constraint template. The Azure Policy Add-On will report ‘InvalidConstraint/Template’ compliance reason code for detected errors after constraint template admission. This change does not impact other compliance reason codes. Customers are encouraged to continue to follow best practices when updating Azure Policy for Kubernetes definitions (i.e. Gator CLI.
  • Starting with Kubernetes 1.29, the default cgroups implementation on Azure Linux AKS nodes will be cgroupsv2. Older versions of Java, .NET and NodeJS do not support memory querying v2 memory constraints and this will lead to out of memory (OOM) issues for workloads. Please test your applications for cgroupsv2 compliance, and read the FAQ for cgroupsv2.
  • Changes to reduce the kube-reserved memory reservation and eviction threshold will not be available in 1.28 as previously shared due to a release issue. These optimizations will be releasing with AKS Kubernetes minor version 1.29, which previews in January 2024. See release calendar.
