I even tore down and recreated our dev cluster. I had the same error reporting in AKS thinking it was the Service Principal causing the issue. Although customers will be notified of image upgrades via the AKS release notes, it might take up to a week for updates to be rolled out in all regions.
AKS provides one new image per week with the latest updates, so it's beneficial to upgrade your node's images regularly for the latest features, including Linux or Windows patches. Additional InformationĪKS supports upgrading the images on a node so you're up to date with the newest OS and runtime updates. We would recommend you to run an az aks upgrade with the -node-image-only flag and once AKS has completed updating the nodes with the latest node images meant for it, check if the issue still persists. The goal of the security hardened host OS is to reduce the surface area of attack and optimize for the deployment of containers in a secure manner. This host OS is based on an Ubuntu 18.04.5 LTS image with more security hardening and optimizations applied. In the process you might also be exposing the cluster to security vulnerabilities as well as breaking changes.ĪKS clusters are deployed on host VMs, which run a security-optimized OS used for containers running on AKS. Any help is Patel, If you are manually updating the AKS node OS version, we strongly recommend against doing so. We are not able to pinpoint the exact issue. We pulled and executed the service-jenkins image using local docker engine to check if there is some issue with image building, but the container is executing normally. Verified the image secret matches with the ACR keys.
