I am trying to set up a kubernetes cluster and running this command on my worker node kubeadm join server:port --token xxx --discovery-token-ca-cert-hash sha256:xxxx and the error i have is

Found multiple CRI endpoints on the host. Please define which one do you wish to use by setting the 'criSocket' field in the kubeadm configuration file: unix:///var/run/containerd/containerd.sock, unix:///var/run/cri-dockerd.sock

I am not sure which container runtime to use here, so i modified the command as kubeadm join server:port --token xxx --discovery-token-ca-cert-hash sha256:xxxx --cri-socket /var/run/crio/crio.sock but the error is

[ERROR CRI]: container runtime is not running: output: I0617 21:55:27.908044 1877581 util_unix.go:103] "Using this endpoint is deprecated, please consider using full URL format" endpoint="/var/run/crio/crio.sock" URL="unix:///var/run/crio/crio.sock"

, error: exit status 1

Can someone suggest the correct approach here

You’re not wrong to post this on ServerFault but I’ll tell you from experience it’s not super likely you’ll get responses here. You would probably be better off on stackoverflow or the Unix stack exchange.

As far as your question, podman is the preferred runtime for K8s. Docker w/K8s frequently breaks because Docker makes no effort to stay CRIO compliant (at least that has been my experience)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
