Kubernetes LTS support

2024-03-15T13:57:07.22+00:00

Hello everyone,

I recently updated the kubernetes version on two of my managed clusters on azure to version 1.28 after previously having upgraded them to 1.27.

I made a mistake and should have stoped on the 1.27 version... my question is, am I able to request LTS from azure for my clusters which are on the 1.28 version ?

I am still learning about these topics so I have a bit of knowhow, this was more of a version confusion mistake because the plan was to keep on 1.27 and request LTS on this version.

Thank you!

    Hello Couto Goncalo, (Goncalo.Couto@ctw.bmwgroup.com),

    Welcome to microsoft Q&A, Thankyou for posting your query here.

    AKS provides one year Community support and one year of long-term support (LTS) to back port security fixes from the community upstream in our public repository.

    AKS version 1.28 does not support LTS version , it is a Standard Support community version

    Migrate from LTS to the next LTS release

    The upstream Kubernetes community supports a two-minor-version upgrade path. The process migrates the objects in your Kubernetes cluster as part of the upgrade process, and provides a tested, and accredited migration path.

    For customers that wish to carry out an in-place migration, the AKS service will migrate your control plane from the previous LTS version to the latest, and then migrate your data plane.

    To carry out an in-place upgrade to the latest LTS version, you need to specify an LTS enabled Kubernetes version as the upgrade target.

    az aks upgrade --resource-group myResourceGroup --name myAKSCluster --kubernetes-version 1.30.2
