Regarding AKS version upgrade decision

Question

I received the following warning email from MS.

None of the environments we maintain here use AKS.

In that case, can we conclude that it is not applicable?

I don't think it's necessary to apply, but I'd like to confirm just to be sure.

From the Azure management screen, click "Azure Service" → "Kubernetes Service" and see that there are no resources, so I decided that the following version upgrade is not necessary.

Upgrade your AKS cluster to a supported Kubernetes version

You’re receiving this notice because you currently use Azure Kubernetes Service (AKS).

Azure Kubernetes Service is retiring v1.25.x on 2 January 2024. We've detected that one or more AKS clusters in your subscription(s) are using Kubernetes v1.25 or lower. To stay within supported versions and service-level agreements (SLA) you have up to 30 days after the version is removed to upgrade. To avoid ever falling out of support and to keep up with Kubernetes versions we recommend turning on auto-upgrade.

Required action

Please upgrade your clustersto 1.25 or higher by 2 January 2024.

• To keep up to date with all AKS releases, subscribe the AKS Releases page.

• To know when the next versions will be introduced or retired check the Kubernetes release calendar for AKS.

Help and support

If you have questions, get answers from community experts in Microsoft Q&A or AKS GitHub. If you have a support plan and you need technical help, create a support request.

Hi @加賀崎 隼

Thank you for reaching out to the Microsoft Q&A platform.

There appears to be an AKS cluster with name reesia_docs_aks under below subscription. If this is not in use or test AKS resource, you can remove it so that you will not be notified by email. This is generic email that is being sent from the azure service side for all the AKS users. Please check the Resource group "freesia-docs-rg" for any AKS resources.
