This release is rolling out to all regions - ETA for conclusion 2021-03-17 for public cloud.
Announcements
- The Azure Kubernetes Service pod security policy (preview) feature will be retired on June 30th, 2021.
- Once GA AKS will default to its new GPU specialized image as the supported option for GPU-capable agent nodes.
- Kubernetes version 1.17 will be deprecated in the last week of March 2021.
- Before k8s 1.20 a bug would allow exec probes to run indefinitely, ignoring any timeoutSeconds configuration value. The previous buggy behavior has been fixed, and timeouts are now enforced. Additionally, this change introduces a new default timeout of 1 second. Please audit all your existing exec probes to make sure that it is appropriate to enforce a 1 second timeout. If not, please provide an explicit timeoutSeconds value that is appropriate for each exec probe.
