Question

I encountered as below when executing sudo kubeadm init Help me~~

$ sudo kubeadm init
[init] Using Kubernetes version: v1.24.1
[preflight] Running pre-flight checks
        [WARNING SystemVerification]: missing optional cgroups: blkio
error execution phase preflight: [preflight] Some fatal errors occurred:
        [ERROR CRI]: container runtime is not running: output: E0605 10:35:34.973561   12491 remote_runtime.go:925] "Status from runtime service failed" err="rpc error: code = Unimplemented desc = unknown service runtime.v1alpha2.RuntimeService"

, error: exit status 1
[preflight] If you know what you are doing, you can make a check non-fatal with `--ignore-preflight-errors=...`
To see the stack trace of this error execute with --v=5 or higher

work around found here : https://github.com/containerd/containerd/issues/4581

rm /etc/containerd/config.toml
systemctl restart containerd
kubeadm init

I don't know why you would remove the config.toml configuration. It clearly states in the issue that disabling the cri plugin via disabled_plugins = ["cri"] causes the issue. – Representation

@Representation At the moment, deleting and commenting out disabled_plugins = ["cri"] has the same effect, as this is the only uncommented line in the config.toml file. But you are right that deleting the file instead of just commenting out the line may cause unexpected errors during future updates. – Hoffer

I followed user@k8s-master:~/$ sudo rm /etc/containerd/config.toml user@k8s-master:~/$ sudo systemctl restart containerd user@k8s-master:~/$ sudo kubeadm init still facing the issue – Dewan

Even after commenting or deleting it is not working in my case for v1.26.1 – Matsumoto

It says, [ERROR CRI]: container runtime is not running: output: time="2023-02-01T16:50:16+05:30" level=fatal msg="validate service connection: CRI v1 runtime API is not implemented for endpoint \"unix:///run/containerd/containerd.sock\": rpc error: code = Unimplemented desc = unknown service runtime.v1.RuntimeService" – Matsumoto

Same as @AbhishekDutta, I have no idea what else to try... – Bravissimo
