This release is rolling out to all regions - ETA for conclusion 2021-02-17 for public cloud.
Announcements
- The Azure Kubernetes Service pod security policy (preview) feature will be retired on May 31st, 2021.
- Once GA AKS will default to its new GPU specialized image as the supported option for GPU-capable agent nodes.
- Starting on the week of 15 February 2021 (Azure China Cloud and Azure Government Cloud users will get this update in the following weeks), we will upgrade AKS clusters Calico network policy from Calico version v3.8.9 to v3.17.1. This upgrade will cause a breaking change to the default behavior of all-interfaces Host Endpoints. For customers that use Host Endpoints, and only these, this version brings a change. Please follow our guidance to apply the appropriate label and Global Network Policy if you want to keep the v3.8.9 default behavior of all-interfaces Host Endpoints.
