Pods stuck in unknown state after reboot

[davigar15]

I'm using latest/edge (with calico cni) and after rebooting the machine I'm getting all pods in Unknown state.

Logs of the calico node:

Calico node started successfully

An interesting this if that calico is detecting the network used for LXD.

Following @ktsakalozos suggestions, I added this in /var/snap/microk8s/current/args/cni-network/cni.yaml and apply that spec.

             - name: IP_AUTODETECTION_METHOD
              value: "can-reach=192.168.0.0"

The calico node did not restart, so I kill it to force the restart. But it did not come up even with microk8s.stop && microk8s.start

This is the tarball generated by microk8s.inspect

Experiencing similar issues with dashboard here. Is microk8s inspect displaying any alert?

[ktsakalozos]

@zar3bski could you attach the microk8s inspect tarball? It is hard to say what may be wrong.

[ktsakalozos]

@davigar15 the attached inspection report seems corrupted.

@zar3bski could you attach the microk8s inspect tarball? It is hard to say what may be wrong.

Here it is.

Since then, I also tried to remove the pods manually. It remained stuck on Pending since then

I also noticed something new

 WARNING:  IPtables FORWARD policy is DROP. Consider enabling traffic forwarding with: sudo iptables -P FORWARD ACCEPT 
The change can be made persistent with: sudo apt-get install iptables-persistent
WARNING:  Docker is installed. 
File "/etc/docker/daemon.json" does not exist. 
You should create it and add the following lines:

}
and then restart docker with: sudo systemctl restart docker
Building the report tarball

Tried both fixes but it did not change much

[PreethikaP]

Facing same issue after restart of VM, the pods are in unknown state.
Though microk8s status and inspect shows all running but pods are in unknown state.
$ microk8s kubectl get pods -n kube-system

Tried restarting service and stop and stop of microk8s service as well.
Have attached microk8s inspect for reference

Thank you for you patience and apologies for the inconvenience this issue may have caused.

When the node starts it needs to invalidate IPs and update pods with new IPs. In kubelet logs you can see this call failing:

On the API server side we see the failed call to "admission.juju.is" to webhook. This webhook is supposed to intercept the REST API call and authorize it. However the pod of the webhook is hosted in the cluster so its IP is not correct so it cannot be found.

We have a bug opened for this at https://bugs.launchpad.net/juju/+bug/1898718

As a temporary workaround you could use Juju 2.7 until this gets addressed.

@ktsakalozos Currently working on a fix for Juju to resolve this. Have updated lp bug.

Fixed committed in Juju. Will be available in 2.8.6

@ktsakalozos still facing the same issue, what might be the case?

[arnitkun]

Issue still exists in 1.22.2, any ideas on how to fix this besides resetting/reinstalling?

[ktsakalozos]

@arnitkun could you please attach a microk8s inspect tarball?

[arnitkun]

@ktsakalozos I shall do it the next time it happens, apparently after another restart everything was good again.

HI all,

I also got same issue. but check checking inspection report i found
The connection to the server 127.0.0.1:16443 was refused - did you specify the right host or port?
on the k8s folder, sometimes kubectl gives same error randomly. I could not think any reason why is that. any tips to check further?

Not sure whether related: #3293

I don't have juju installed in my machine. After reboot, all the pods status is unknown. Is there any workaround?

my pods also went to unknown mode, I guess after rebooting this happened for both of my servers which has microk8s and centOS7, I post issue here also:

Any Idea how can I resolve it? don't think it is related to docker or containerd or kernel version since it was working perfectly for 7-8 monthes!

Is it possible that the reboot caused the system to start from another kernel?

tnx for ur reply:
No, I don't think so, since there is only one kernel on both of my Centos 7 severs which is kernel-3.10.0-1160.el7.x86_64 ; one server is connected to the internet and another is completely isolated and I have done nothing on it and after reboot unexpectedly this error happened!
don't guess it is related to kernel and containerd version incompatibility due to runc vulnerability measures ...the reaseon I think so is that my docker on the same machine that microk8s (or better say containerd that running inside microk8s ) gives the error: "can't copy bootstrap data to pipe: write init-p: broken pipe" can create container e.g :

#docker run -itd busybox:latest
#docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
7328b5736817 busybox:latest "sh" 3 seconds ago Up 3 seconds flamboyant_sanderson

the environement is the same, so if container gets created with docker on the same machine with 3.xx kernel and docker-ce and containerd version as following then we can eliminate the solution that says: "with upgrade of kernel version or downgrade docker & containerd version the problem will get solved!"
I think this problem is related to microk8s and containerd inside it, deams like this issue is for Ubuntu as well:
