    Apparently it is my fault this time. My ansible playbook did not override config.toml file as I expected. Am sorry for taking up your time, default installation instructions work great.
    

    In the config.toml file installed by package containerd.io there is the line disabled_plugins = ["cri"] that am guessing creating the issue. That maybe is bad default setting to have in the package containerd.io but that is for another issue/bug.
    

    Closing.

    Docker (by default) uses that config for the containerd they install via containerd.io packages.  Grr.  been causing similar ^ issues for k8s users for years. :-)
    
          
    I followed the official instructions here https://kubernetes.io/docs/setup/production-environment/container-runtimes/
    

    and I was getting similar error

    I checked  /etc/containerd/config.toml  and saw  'disabled_plugins = []'
    

    Note the only thing I changed in the config.toml was to use systemd as true -it was different from the way docs has mentioned
    
(maybe this was the problem?)
    

    [plugins."io.containerd.grpc.v1.cri"]
    systemd_cgroup = false --> to true

    from docs
    

    [plugins."io.containerd.grpc.v1.cri".containerd.runtimes.runc]
  [plugins."io.containerd.grpc.v1.cri".containerd.runtimes.runc.options]
    SystemdCgroup = true

    deleting this config.toml as given in the first post and restarting containerd service solved and kubeadm could proceed

    This is definitely a bug. For the worker node I followed the docs exact and I was getting this error

    This comment saved my day 👍 . The default docker configuration removes CRI.

    Heads up, this just happened to me on a clean install of Kubernetes v1.24.0 on Ubunutu 20.04.4 LTS. The original fix helped me as well.

    there is no dockershim in kubernetes v1.24 you'll need to install and configure containerd or cri-o
    

    I have a same issue with kubeadm v1.24.0 in CentOS 7.9
    

    unfortunately the config in the containerd.io package has, since forever, had a bad configuration for kubernetes tools.  The bad configuration is they install a version of the config for containerd that is only good for docker. This config needs to be replaced at least with the default containerd config.. and you can modify it from there if you like.
    

    "containerd config default > /etc/containerd/config.toml" will overwrite docker's version of the config and replace it with containerd's version of the config.. which also works just fine for docker.  Then restart containerd.

    Thank you very much for your reply. I will try it.
    

    I had this same error. "failed to pull images... rpc error ...unknown service...
    
I had raised a ticket and was redirected to this page.
    

    Referring the steps given on top, it solved my problem for K8s 1.24 on RHEL 8.2
    
However same steps did not help me on K8s 1.24 on CentOS 7.9. Here I continue to receive same error msg! :(

    containerd config default > /etc/containerd/config.toml
sed -i 's/SystemdCgroup \= false/SystemdCgroup \= true/' /etc/containerd/config.toml
sed -i 's/snapshotter = "overlayfs"/snapshotter = "native"/' /etc/containerd/config.toml
    

    Case 2：kuberspray installs kubernetes 1.25.3 and reports this error solution:
    

  • containerd: v1.6.9
    • 

  • kubelet: 1.25.3
    • 

    sed -i 's@# containerd_snapshotter: "native"@containerd_snapshotter: "native"@g' inventory/mycluster/group_vars/all/containerd.yml
    

    Then rerun kubespray
    
          
    in my case path of docker installation is wrong and that is causes the same issue .
    
issue was in kubelet that is exited with status 1
    
OS-ubuntu 20.04
    

    1 . install docker through k8s guide (command - apt install docker.io  does not install latest version of docker and there can
    
issue in installation of containerd .  )
    
https://docs.docker.com/engine/install/ubuntu/      -- it install latest version of docker as well as containerd.
    
2. after installtion there will be  /etc/containerd/config.toml by default . just delete it
    
3. systemctl restart containerd
    
4. systemctl restart kubelet > kubeadm init
    
          
    Got this error too

	[ERROR CRI]: container runtime is not running: output: E0103 00:14:31.026921    5282 remote_runtime.go:948] "Status from runtime service failed" err="rpc error: code = Unimplemented desc = unknown service runtime.v1alpha2.RuntimeService"

, error: exit status 1

    The following steps worked for me ->
    

    sudo apt-get update && sudo apt-get install -y containerd
sudo mkdir -p /etc/containerd
sudo containerd config default | sudo tee /etc/containerd/config.toml
# update SystemdCgroup to true in `/etc/containerd/config.toml`
sudo systemctl restart containerd
          
    I just ran  apt-get upgrade and now my control plane and all workers are failing to run containerd and thus also kubelet. The logs for sudo service containerd status show:
    

    Jan 24 23:15:55 kube-master containerd[431]: time="2023-01-24T23:15:55.608380181-06:00" level=info msg="loading plugin \"io.containerd.grpc.v1.cri\"..." type=io.containerd.grpc.v1

    It seems the apt-get upgrade reverted my changes to /etc/containerd/config.toml and set SystemdCgroup back to false as well as systemd_cgroup. Why does this keep on reverting? Additionally, why are these defaulted to false?
    

    Seems like perhaps there should be some enhanced logic in the generate default config that detects if systemd is in use and set those values to true?
    

    Update + solution: in my case, I had to set SystemdCgroup = true and systemd_cgroup = false. Leaving systemd_cgroup = true resulted in an error on containerd startup.
    

    Problem Following Kubernetes official installation instruction for containerd and kubeadm init will fail with unknown service runtime.v1alpha2.RuntimeService.

    Thank you, I solved the problem using your solution!
    
          
    I have the same problem when I try to join to master node and my containerd is activate, nothing works

    Got the same issue and fixed it by installing the containerd.io package from the docker repository instead of the one from ubuntu's repository.
    
see: https://docs.docker.com/engine/install/ubuntu/#set-up-the-repository
    

    I have ubuntu 22.04.2 on VMs and raspberry pies
    

    Also it seems there is presently an issue to retrieve the gpg key from https://packages.cloud.google.com/apt/doc/apt-key.gpg
    
          
    I struggled with this too. The solution for me was to comment this line out in /etc/containerd/config.toml
    

    disabled_plugins = ["cri"]
          
    Refer to Three pages of Kubernetes Doc:
    

  • https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/install-kubeadm/
    • 

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

  • https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/create-cluster-kubeadm/
    • 

    Steps :
    

  • complete the Pre-requisite ( pages 1 & 2 )
    • 

  • install CRI from page 2 ( For Containered & Docker-  https://docs.docker.com/engine/install/ubuntu/ )
    • 

  • Make changes in /etc/containerd/config.toml ( page 2 ) then restart containerd
    • 

  • Install kubectl, kubeadm, kubelet ( page 1 )  then systemctl daemon-reload
    • 

  • kubeadm init (  page 3 )
    • 

  • install CNI (  for weave net -  https://www.weave.works/docs/net/latest/kubernetes/kube-addon/)
    • 

  • systemctl daemon-reload && kubectl get nodes
    • 

    OR  can use single shell script for both master-node & worker node configuration

    …Service.
when trying to install the kube mast on a debian image you get " unknown service runtime.v1alpha2.RuntimeService." due to the fact that the installation of 'containerd' from the default debian repository is not updated (for referance - containerd/containerd#4581). To fix it I added the rpository of containrd and installed from their, a documentation of how to do it as a referance can be found here - https://docs.docker.com/engine/install/debian/#uninstall-old-versions.
    
my bash history from the new control plane is below, it works.

   63  sudo kubeadm init --pod-network-cidr 192.168.0.0/16 --kubernetes-version 1.26.0
          
    It got fixed for me finally:
    

    Update contained to the latest and fix toml file with below changes:
    

    disabled_plugins = ["cri"]   -->> disabled_plugins = [""]
    

    Done.
    
Thnak me later ;)
