cri-dockerd sandbox diffing from kubadm sanbox

[Toavina23]

I am getting this error message when initializing my kubernetes cluster
detected that the sandbox image "registry.k8s.io/pause:3.6" of the container runtime is inconsistent with that used by kubeadm. It is recommended that using "registry.k8s.io/pause:3.9" as the CRI sandbox image

The initialization is complete and the cluster is operational but I am a bit worried about the risk of ignoring this warning message.

is there a fix to it ? I did not find a way to override the cri-dockerd sandbox version

Unfortunately the documentation is a bit confusing, it ended up under "Mirantis" header:

https://kubernetes.io/docs/setup/production-environment/container-runtimes/#docker

Overriding the sandbox (pause) image

The cri-dockerd adapter accepts a command line argument for specifying which container image to use as the Pod infrastructure container (“pause image”). The command line argument to use is --pod-infra-container-image.

It will be updated to use pause version 3.9 by default:

• Return the sandbox image status as "Pinned" #194

Okay thanks for the informations.
