Kubernetes 1.29 - node NotReady and pods still pending after weave deployment #3

Open mvrk69 opened 7 months ago

mvrk69 commented 7 months ago

Hi,

I deployed a kubernetes 1.29 cluster and after deploying weave, the node is NotReady and the pods are still in pending. Same thing with kuberntes 1.28 Last version where it works fine is kubernetes 1.27

Anything else we need to know?

OS: Fedora CoreOS 39

Any idea what might be wrong?

rajch commented 7 months ago

From the logs, it seems that the weave initialisation procedure has not been able to write a files called /etc/cni/net.d/10-weave.conflist, and therefore the CNI plugin is not enabled. Probably a permissions issue, especially because this is CoreOS. This should affect all versions of Kubernetes, not just later ones.

To confirm, could you please do the following for me?

  1. Run the following, and paste the results here: 
    $ kubectl logs -n kube-system <weave-net-pod> init
  2. You could also manually create the file on all your nodes. The contents are: 
    {
"cniVersion": "1.0.0",
"name": "weave",
"disableCheck": true,
"plugins": [
    {
        "name": "weave",
        "type": "weave-net",
        "hairpinMode": true
    },
    {
        "type": "portmap",
        "capabilities": {"portMappings": true},
        "snat": true
    }
]
}
  3. How did you set up Kubernetes? Using kubeadm?
mvrk69 commented 7 months ago

1:

kubectl logs -n kube-system weave-net-gftst init error: container init is not valid for pod weave-net-gftst

The container name seems to be weave-init not init, but no logs, returns empty: kubectl logs -n kube-system weave-net-gftst weave-init

2: I see the file there:

root@k8sm01:~# ll /etc/cni/net.d/
total 8
-rw-r--r--. 1 root root 344 Apr 15 16:06 10-weave.conflist
-rw-r--r--. 1 root root 393 Apr 15 16:05 11-crio-ipv4-bridge.conflist

And the file seems to have the same contents you posted:

root@k8sm01:~# cat /etc/cni/net.d/10-weave.conflist
{
    "cniVersion": "1.0.0",
    "name": "weave",
    "disableCheck": true,
    "plugins": [
        {
            "name": "weave",
            "type": "weave-net",
            "hairpinMode": true
        },
        {
            "type": "portmap",
            "capabilities": {"portMappings": true},
            "snat": true
        }
    ]
}

3: yes, i used kubeadm:

kubeadm init --config kubeadm-config.yml --upload-certs

kubeadm-config.yml:

Sorry, the container name was indeed weave-init. Okay. So the weave initialisation completed without issues, and the weave pod is also in running state and producing logs. At this point, weave is ready, and the NotReady taint should automatically be removed by the kubelet. Also, the coredns pods should go into ContainerCreating state.

Can we check the output of kubectl get pods -n kube-system -o wide and kubectl describe node k8sm01? Also, just to re-check the permissions problem, ls -l /etc/cni/net.d (it should have 744 permissions).

Yes, weave net is up and running, but the taint is not gone. I think a kubelet restart or a node restart will solve the problem.

I currently test weave net with kubernetes versions 1.27 through 1.29, on clusters running debian linux on amd64 and arm64. It works in all those cases. I also use kubeadm, with settings pretty similar to yours. Perhaps I should add coreos to the test mix.

mvrk69 commented 7 months ago

I tried restarting kubelet and also reboot, and still no go.

rajch commented 7 months ago

I apologise for inconvenience. I'll try and replicate your environment, and see if I can find the problem. The only thing out of place in your logs is that kubelet has still not detected the CNI setup, even though Weave Net has indicated that the network is available. You can see that in the Conditions: section of the kubectl describe node output. Quoting the relevant part below:

I tried setting up a cluster on CoreOS, and faced exactly the same problem. But after a long time (over 15 minutes), the node became Ready. This happened with a different CNI as well. I wasn't able to diagnose what the problem was. Every log gave the expected responses: no errors, no warnings. Only kubelet kept logging that there were no configuration files in /etc/cni/net.d/, but the files were very much there. After a long-ish time, suddenly kubelet reported that the node was now ready. I have not observed this behaviour on other operating systems. I'm tempted to just blame CoreOS, because weave does everything it is supposed to do - and the same symptoms can be seen for at least one other CNI plugin. But I will observe some more, and report back here.

mvrk69 commented 7 months ago

Yes, seems happens to flannel and weave on clusters above 1.27 on CoreOS, though works fine with calico.

Also with Openshift OVN-Kubernetes.
