Ubuntu
20.04 on Azure Kubernetes Service will be retired on March 17, 2027.
Please transition to a supported Ubuntu version by that date.
Ubuntu
20.04 has been replaced by newer
supported versions,
including Ubuntu 22.04 and Ubuntu 24.04. We encourage you to transition to
Ubuntu 22.04+ before the retirement date.
Starting
on March 17, 2027, AKS will no longer create new node images for Ubuntu 20.04 or
provide security updates. Existing node images will be deleted. Your node pools
will be unsupported and you will no longer be able to scale.
Required action:
If
you’re currently using Ubuntu 20.04 with a Confidential
VM (CVM) on AKS, follow our
instructions to upgrade your
Kubernetes version to 1.33+ where Ubuntu 24.04 will be the default Ubuntu
version for CVM workloads.
If
you’re currently using Ubuntu 20.04 with Federal Information Process Standard (FIPS) on AKS, follow our instructions to upgrade your
Kubernetes version to 1.34+ where Ubuntu 22.04 will be the default Ubuntu
version for FIPS workloads.
To
avoid service disruptions, scaling restrictions, and remain supported, please
follow our instructions to upgrade your Kubernetes version to 1.34+ by March 17, 2027. For more information on this retirement, see AKS
