LAB 4.1 Usage of CRI endpoints without URL scheme is deprecated

Although I've updated crictl configuration with
sudo crictl config --set runtime-endpoint=unix:///run/containerd/containerd.sock \ --set image-endpoint=unix:///run/containerd/containerd.sock
when running kubeadm upgrade plan
I get the following warning:
W0826 11:57:17.313190 4480 initconfiguration.go:120] Usage of CRI endpoints without URL scheme is deprecated and can cause kubelet errors in the future. Automatically prepending scheme "unix" to the "criSocket" with value "/run/containerd/containerd.sock". Please update your configuration!
I can perform upgrade of the cluster but was wondering why do I get this warning if entries are already prepended with unix://
?

Hi @k0dard,
The
--set
option is one way to set the runtime and image endpoints. An alternate way is to create the/etc/crictl.yaml
file.
I used the following command for the crictl.yaml file, based on the official crictl installation and usage documentation, and did not run into any usage errors:$ sudo -c sh 'cat <<EOF > /etc/crictl.yaml runtime-endpoint: unix:///run/containerd/containerd.sock image-endpoint: unix:///run/containerd/containerd.sock timeout: 2 debug: false pull-image-on-create: false EOF'

This is now part of the lab and I double-checked the file
/etc/crictl.yaml
. It looks almost similar to yours @chrispokorni. However I get the same warning message as @k0dard.0 -
Typically warnings can be disregarded and things should work as expected. However, after taking a closer look at the latest docs, it seems this config update may be expected by the kubeadm bootstrapping tool from its
/var/lib/kubelet/kubeadm-flags.env
config file. Try to update the value of--cri-socket
in that file if needed, and try running thekubeadm upgrade plan
command again.Regards,

Got it working. Thanks.
