AKS - Release 2020-04-13

Published by palma21 over 4 years ago

This release is rolling out to all regions

Important Service Updates

  • AKS API version 2020-04-01 (to be published) will default to VMSS (Virtual Machine Scale Sets), SLB (Standard Load Balancer) and RBAC enabled.
  • AKS has introduced AKS Ubuntu 18.04 in preview. During this time we will provide both OS versions side by side. After AKS Ubuntu 18.04 is GA, on the next cluster upgrade, clusters running AKS Ubuntu 16.04 will receive this new image.

Release Notes

  • Bug Fixes
    • Added CriticalAddonsOnly toleration for calico-typha-horizontal-autoscaler
    • Fixed a bug where the ILB backend bool would be removed after a manual VMSS update-instances command was issued.
  • Features
    • AKS has now introduced a new Mode property for nodepools. This will allow you to set nodepools as System or User nodepools. System nodepools will have additional validations and will be preferred by system pods, while User pool will have more lax validations and can perform additional operations like scale to 0 nodes or be removed from the cluster. Each cluster needs at least one system pool. All details here: https://aka.ms/aks/nodepool/mode
      • System/User nodepools are available from core CLI version 2.3.1 or greater (or latest preview extension 0.4.43)
      • Nodepool mode requires API 2020-03-01 or greater
    • AKS now allows User nodepools to scale to 0.
    • AKS Diagnostics - Added networking and connectivity checks through our new Cluster Network Configuration detector. This allows you to check DNS and subnet related issues that may have impacted your cluster. It also highlights your network configuration to give you all this information at your fingertips.

Service Updates

  • With the official 2019-11-04 Azure CLI release, AKS will default new cluster
    creates to VM Scale-Sets and Standard Load Balancers (VMSS/SLB) instead of VM
    Availability Sets and Basic Load Balancers (VMAS/BLB).
  • From 2019-10-14 AKS Portal will default new cluster
    creates to VM Scale-Sets and Standard Load Balancers (VMSS/SLB) instead of VM

    choose VMAS and BLB.

Release 2019-09-30

This release is rolling out to all regions

Service Updates

  • With the official 2019-11-04 Azure CLI release, AKS will default new cluster
    creates to VM Scale-Sets and Standard Load Balancers (VMSS/SLB) instead of VM
    Availability Sets and Basic Load Balancers (VMAS/BLB).

    • Fix a bug where the removal of an outbound rule from standard load balancer
      in the AKS node resource group could cause the failure of subsequent
      cluster operations.
    • Fixed the issue impacting GPU enabled clusters being unable to install the
      required NVidia drivers.
    • Fixed an issue where customers could encounter a CSE (custom script
      extension) error 99 during operations.
    • Fixed an issue with the Azure Portal cluster metrics multiplying the metric
      count based on the viewed window of time. Moving forward the default for
      these metrics will be correctly set to average() as opposed to sum().
      • For customers with metrics already enabled and in-use in portal, the sum()
        type will continue to be supported.
  • Component Updates
    • AKS-Engine has been updated to v0.40.1
  • Preview Features
    • Fixed an issue where nodes provisioned by cluster autoscaler would be
      de-provisioned when resetting or updating AAD credentials.
