Container image types supported by AKS

Question

I want to know which container images are supported by AKS (Azure Kubernetes Service).
Is it the same as the types supported by ACR (Azure Container Registry)?
(For example, all container images whose format is the "Docker Image Manifest Version 2, Schema 2" are supported by AKS? What about other image types?)

Answer 1

Hello @Hachiya, Yuuki/蜂谷 勇揮

Both Linux and Windows node pools use containerd as a runtime since Kubernetes version 1.19 and greater.
Containerd runtime is software that executes containers and manages container images on a node. The runtime helps abstract away sys-calls or operating system (OS) specific functionality to run containers on Linux or Windows.

You are right, AKS as long as containerd support Docker Image Manifest V2, Schema 1, Docker Image Manifest V2, Schema 2, OCI images

Answer 2

AKS supports the Docker Image format and it can be integrated with Azure Container Registry.

Since AKS can be integrated with ACR, it can pull all the image formats available in ACR. The following URL states the supported image formats in ACR

Hope this helps
