How to list all local images on a Kubernetes node (AKS)

Our deployment's imagePullPolicy wasn't set for a while, which means it used IfNotPresent.
If I understand correctly, each k8s node stored the images locally so they can be reused on the next deployment if necessary.

Is it possible to list/show all the stored local images per node in an AKS cluster

Per doc the solution should be to list all images of all running containers (though this does not list pulled images that are not currently used) :

kubectl get pods --all-namespaces -o jsonpath="{.items[*].spec.containers[*].image}" |\
tr -s '[[:space:]]' '\n' |\
sort |\
uniq -c

AKS uses containerd-shim enter image description here

For listing out the container images on AKS docker-cli is unavailable, use crictl instead. It is located at

ls /usr/local/bin
bpftrace  crictl  health-monitor.sh  kubectl  kubelet

Use crictl images to list out container images on AKS worker nodes.

Yes, you have to firstly check the node to which pod has been scheduled against that microservice.

kubectl -n namespace get pods -o wide

Once you get the node, try to setup an ssh connection with the node, this link can be used to do it.

Then you can execute following command in that VM

docker images

It will give you all docker images in that

As docker is installed on every node of the k8s cluster, to list/show local images per node, you need login to the worker node and you could run :

    docker images

This would give you the list of all the images on that particular node.
