Kubeadm: runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized

It seems that the nodes are not getting flannel because they are on amd64 architecture

I'm not expert of flannel, but I think you should check product documentation for how to make it work in environment with mixed platforms

That's a good point, but how about error message - it seems really unrelated.

runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized

It looks like some CNI config files are missing in /etc/cni/net.d but why?
I'm now trying different docker 18.03ce as suggested on the slack channel (17.03 was actually suggested, but there is no 17.03 for Ubuntu 18.04).

Labels with arch name don't match indeed. But next label beta.kubernetes.io/os=linux is the same on all 3 servers.

The same happens with Docker 18.03ce. I don't see any difference, this is not looking like a docker issue. This looks like some CNI config issue.

hi,

Master: Bare metal server 96 cores, ARM64, 128G RAM, swap turned off.
Nodes (2): bare metal server 48 cores, AMD64, 256G RAM, swap tuned off x 2.

these are some _nice_ specs.

the way i test things is the following - if something doesn't work with weavenet, i try flannel and the other way around.

so please try weave and if your CNI setup works with it, then this is CNI plugin related.

while the kubeadm team supports plugins and addons, we usually delegate issues to their respective maintainers because we don't have the bandwidth to handle everything.

Sure, I've tried weave a few iterations ago. It ended in a container restart loop.
Will now try docker 17.03 to exclude docker issue (17.03 is supposed to be supported very well).

So this is not a docker issue. On 17.03 the same:

now will try weave net as suggested on the issue

I'll try weave now and post results here.

So, I've tried weave net and it is not working:
On master: kubectl get nodes:

So, summing up. It is impossible to install Kubernetes cluster with just single master and single worker node on Ubuntu 18.04.
I think there should be an installation instruction how to set up k8s step-by-step using kubeadm on the newest LTS Ubuntu.

i think 18.04 broke both in terms of the Docker it bundles and for systemd-resolved.
so yeah, it's really hard to write guides for every single distro flavor out there and we can't really maintain these efficiently.

also while kubeadm is the frontend here, the issue really could be unrelated to kubeadm itself.

some questions:

• have you been running amd64 + arm64 clusters successfully with recent kubernetes versions?
• i wonder if this is a proxy issue. are the nodes behind a proxy?
• what are the contents of /var/lib/kubelet/kubeadm-flags.env when your start kubeadm join/init on the 3 nodes?
• are those the only interesting contents from journalctl -xeu kubelet? is that only on the master node - what about the others? you can dump these in a github gist or a http://pastebin.com for me too look at.

• have you been running amd64 + arm64 clusters successfully with recent kubernetes versions? No this is my first try, but I will also try to install master on amd64 host and a single node with another amd64 host to exclude arm64 related issue
• i wonder if this is a proxy issue. are the nodes behind a proxy? no proxy at all, all 3 servers have static IPs
• what are the contents of /var/lib/kubelet/kubeadm-flags.env when your start kubeadm join/init on the 3 nodes?
  master (devstats.team.io, arm64):

KUBELET_KUBEADM_ARGS=--cgroup-driver=cgroupfs --cni-bin-dir=/opt/cni/bin --cni-conf-dir=/etc/cni/net.d --network-plugin=cni --resolv-conf=/run/systemd/resolve/resolv.conf

node (cncftest.io, amd64):

KUBELET_KUBEADM_ARGS=--cgroup-driver=cgroupfs --cni-bin-dir=/opt/cni/bin --cni-conf-dir=/etc/cni/net.d --network-plugin=cni --resolv-conf=/run/systemd/resolve/resolv.conf

node (devstats.cncf.io, amd64):

KUBELET_KUBEADM_ARGS=--cgroup-driver=cgroupfs --cni-bin-dir=/opt/cni/bin --cni-conf-dir=/etc/cni/net.d --network-plugin=cni --resolv-conf=/run/systemd/resolve/resolv.conf

• are those the only interesting contents from journalctl -xeu kubelet? is that only on the master node - what about the others? you can dump these in a github gist or a http://pastebin.com for me too look at.

Pastebins: master, node.

So, I've installed master kubeadm init on the amd64 host and tried weave net and the result is exactly the same as when trying this on the arm64 host:

• Back-off restarting failed container
• runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized

There is a small progress.
I've installed master on amd64 then one node on amd64 too. All worked fine.
I've added arm64 node and now I have:
master amd64: Ready
node amd64: Ready
node arm64: NotReady: runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized

• So it looks like flannel net plugin cannot talk between different architectures and arm64 cannot be used as a master at all.
• Weave net plugin is not working at all (without even adding nodes). Master is always in NotReady state no matter if arch is amd64 or arm64.
• In all those cases the reason for 'NotReady' is always the same: runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized

Any suggestions what should I do? Where should I report this? I already have a 2 nodes cluster (master and node amd64) but I want to help resolve this issue so one can use any arch master with any arch nodes just OOTB.

@lukaszgryglicki
kube-flannel.yml deploys the flannel container for one architecture only. This is why on nodes with different architecture the cni plugin doesn't start and the node never get ready

I never tried by myself, but I guess you can deploy two hacked flannel manifest with different taints (ands names) for avoiding to mix up things, but again my suggestions is to ask to flannel people if there are already instructions about how to do this.

But I've tweaked manifest on arm64 as suggested in the tutorial. Replaced amd64 with arm64.
So maybe I'll create an issue for flannell and paste a link to this thread.

And now why wave net fails on both archs with the same cni related bug? Maybe create an issue for weave as well and also link to this thread?

@lukaszgryglicki
When you twicked kube-flannel.yml for arm, it stops to works on amd machines... This is why I'm guessing that deploying 2 well-twicked manifests, one for arm and one for amd, can solve your issue.

And now that I think of, might be you should fix the same issue with kube-proxy daemon set as well, but I can't test this now, sorry

For the problem you have with weave I don't have enough info. One problem might be that weave doesn't works with --pod-network-cidr=10.244.0.0/16, but going back to the initial issue, I don't know by hearth if weave works out of the box on mixed platforms or not.

So I should deploy two different manifests for flannel on a master, right? No matter if master happens to be arm64 or amd64, right? Should Master handle spawning correct arch deployment on itself and nodes?
Not sure what do you mean here:

And now that I think of, might be you should fix the same issue with kube-proxy daemon set as well, but I can't test this now, sorry

I didn't use --pod-network-cidr=10.244.0.0/16 for weave. I've used just kubeadm init.
I've used --pod-network-cidr=10.244.0.0/16 only for flannel attempts. Just like the docs say.

cc @luxas - I've seen you've created some docs about multi-arch k8s deployments, maybe you can have some feedback?

@lukasredynk

yeah, so this is an arch issue after all, thanks for confirming.
let's focus on flannel here as the weave issue seems like a tangent one.

have a look this by @luxas for context, if not seen it already:
https://github.com/luxas/kubeadm-workshop

Should Master handle spawning correct arch deployment on itself and nodes?

_it should_ but the manifest you are downloading is not a "fat" one:
https://raw.githubusercontent.com/coreos/flannel/v0.10.0/Documentation/kube-flannel.yml

as far as i understand it the arch taints are propagated and you need to fix that with kubectl on each node (?).

looks like a "fat" manifest is in master and was added here:
https://github.com/coreos/flannel/commit/c5d10c8b16d7c43bfa6e8408673c6d95404bd807#diff-7891b552b026259e99d479b5e30d31ca

related issue/pr:
https://github.com/coreos/flannel/issues/663
https://github.com/coreos/flannel/pull/989

my assumption is that this is bleeding edge and you have to use:

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

so bring the cluster down and give that a try and hope it works.
our CNI docs would need a bump, yet this needs to happen when flannel-next is released.

OK, will try after the weekend and post my results here. Thanks.

@lukaszgryglicki hi, did you get this working using the new flannel manifest?

Not yet, I'll try today.

OK finally worked:

root@devstats:/root# kubectl get nodes
NAME               STATUS    ROLES     AGE       VERSION
cncftest.io        Ready     <none>    39s       v1.11.1

devstats.team.io   Ready     master    12m       v1.11.1

Fat mainifest from flannel master branch helped.
Thanks, this can be closed.

Hi guys, I'm in the same situation.
I have worker nodes in Ready state, but the flannel on arm64 keep crashing with this error:
1 main.go:232] Failed to create SubnetManager: error retrieving pod spec for 'kube-system/kube-flannel-ds-arm64-m5jfd': Get https://10.96.0.1:443/api/v1/namespaces/kube-system/pods/kube-flannel-ds-arm64-m5jfd: dial tcp 10.96.0.1:443: i/o timeout
@lukasredynk did it work for you?

any idea?

The error seems different, but did you use the fat manifest: https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml ?
It contains manifests for multiple archs.

Yes I am:

The problem now it the flannel container that doesn't stay up on arm. :(

it does on amd64 and arm64 - works for me.
Unfortunately, I can't help with arm (32 bit), I have no arm machine available.

I'm on arm64 but thanks, I'll continue to investigate...

Ohh then sorry, I thought you're on arm.
Anyway, I'm also quite new to this, so you need to wait for other guys to help.
Please paste the output of kubectl describe pods --all-namespace and possible output of other commands that I've posted in this thread. This may help somebody to track the real problem.

Thanks @lukaszgryglicki,
this is the output of describe pods: https://pastebin.com/kBVPYsMd

@lukaszgryglicki
glad it worked in the end.
i will document the fat manifest usage for flannel in the docs, since i have no idea when 0.11.0 will be released.

@Leen15

relevant from the failing pod:

  Warning  FailedCreatePodSandBox  3m (x5327 over 7h)  kubelet, nanopi-neo-plus2  (combined from similar events): Failed create pod sandbox: rpc error: code = Unknown desc = failed to set up sandbox container "9ddb551d520a757f4f8ff81d1dbfde50a98a5ec65385673a5a49a79e23a3243b" network for pod "arm-test-7894bfffd-njdcc": NetworkPlugin cni failed to set up pod "arm-test-7894bfffd-njdcc_default" network: open /run/flannel/subnet.env: no such file or directory

are you adding --pod-network-cidr=... which is needed for flannel?

also try this guide:
https://github.com/kubernetes/kubernetes/issues/36575#issuecomment-264622923

@neolit123 yes, I found the problem: flannel didn't create the Virtual network interface (cni and flannel0).
I dont know the reason and I failed to resolve it after several hours.
I gave up and switched to swarm.

ok, understood. in that case i'm closing the issue.
thanks.

I ran into the same problem too, and I found that the node can not pull the required images because of the GFW in china, so I pull the images manaully and it recover ok

I run this command and it solved my issue:

1. kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

This creates a file in /etc/cni/net.d directory with the name of 10-flannel.conflist. I believe that kubernetes requires a network, which is set by this package.

Please help

Hi Athir,

         Please check out logs in /var/logs/messages section of your Master node. You can find an actual error in those logs. But here are some general tips.

i. Always concentrate on your Master node first.
ii. Install docker engine on it and fetch all images which are being used for kubernetes. When everything will be in running form, then add nodes to the master. it will solve all the issue. I saw some articles on the internet, which try to fetch some images after attaching the slave nodes. That practice causes some trouble.

Hi saddique164, Thanks for your suggestions. Yeah as you said I deployed another new slave node yesterday and was able to join the Master without any issues.

Sorry, I cannot help, I don't have ARM64 nodes anymore, now I have a 4 node AMD64 bare-metal cluster.

The file /etc/cni/net.d/10-flannel.conflist was missing cniVersion key in its config.

Adding "cniVersion": "0.2.0" solved the issue.

flannel is not very actively maintained. i recommend calico or weavenet.

the flannel repository needed a fix.
the kubeadm guide for installing flannel was just updated, see:
https://github.com/kubernetes/website/pull/16575/files

Faced the same issue here.
kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml.

Worked for me.

docker: network plugin is not ready: cni config uninitialized

Reinstall docker on the notready node.
Worked for me.

I run this command and it solved my issue:

1. kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

This creates a file in /etc/cni/net.d directory with the name of 10-flannel.conflist. I believe that kubernetes requires a network, which is set by this package.
My cluster is in the following state:

NAME STATUS ROLES AGE VERSION
k8s-master Ready master 3h37m v1.14.1
node001 Ready 3h6m v1.14.1
node02 Ready 167m v1.14.1

That just did it!

I had a similar case where I was creating the network plugin before linking the workers, which kept the /etc/cni/net.d missing.
I re-executed the configuration after linking the worker nodes using:
kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
As a result, the configuration in /etc/cni/net.d was created successfully and the node showed in a Ready state.

Hope that helps anyone with the same issue.

Ran that Command on Master Machine and everything is in Ready state now. Thank you @saddique164 .

The quickest way is to add Flannel into the Kubernetes on either AMD64 Architecture.

1. Update kube-flannel.yaml

$ curl https://rawgit.com/coreos/flannel/master/Documentation/kube-flannel.yml \
> kube-flannel.yaml

2. Complete Flannel network setup

$ kubectl apply -f kube-flannel.yaml

I am using the kubernetes 1.18 version.

I used this: kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

There was no file created under /etc/cni/net.d
The master node is NotReady whereas slaves are in Ready state

1. can you run kubectl command on master?
2. can you check your kubelet is running on master? or run this : systemctl restart kubelet.
3. if kubelet is restarting or auto-restart, then run journal -u kubelet and check the logs. You will find the error.

NOTE: This seems to be kubelet issue.

1. Yes I can run kubectl commands.
2. Kubectl runs and then fails.
3. This is what I see in the errors from journactl -u kubelet:

if nothing comes then run this one:
kubectl describe pod kube-flannel-ds-amd64-5tmhp -n kube-system

How many nodes are running for you? IN the cluster? one node is doing this problem. This is called daemonset. They run on every node. Your control plan is not accepting the request from it. So i will suggest you to follow the following steps.

1. first drain the worker nodes one by one.
   Kubectl drain nodename
2. then delete them.
   kubectl delete node nodename
3. wait for the master node to come ready. if it doesn't come. run this command.
   kubeadm reset
4. again initalize the kubeadm
   kubeadm init
5. run this command
   kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
6. get the command from the master and run it in the worker nodes to connect them.

This process will work.

kubectl get nodes:

NAME     STATUS     ROLES    AGE   VERSION
master   NotReady   master   26h   v1.18.5
slave1   Ready      <none>   26h   v1.18.5
slave2   Ready      <none>   26h   v1.18.5

I tried the steps you mentioned:

This is what I get.

        Unfortunately, an error has occurred:
                timed out waiting for the condition

        This error is likely caused by:
                - The kubelet is not running
                - The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)

        If you are on a systemd-powered system, you can try to troubleshoot the error with the following commands:
                - 'systemctl status kubelet'
                - 'journalctl -xeu kubelet'

        Additionally, a control plane component may have crashed or exited when started by the container runtime.
        To troubleshoot, list all containers using your preferred container runtimes CLI.

        Here is one example how you may list all Kubernetes containers running in docker:
                - 'docker ps -a | grep kube | grep -v pause'
                Once you have found the failing container, you can inspect its logs with:
                - 'docker logs CONTAINERID'

error execution phase wait-control-plane: couldn't initialize a Kubernetes cluster
To see the stack trace of this error execute with --v=5 or higher

drain all the nodes except master and concentrate on that. When it will be ready then go to add others.

Draining nodes and then kubeadm reset and init doesn't help. The cluster is not initialized afterward.

My problem was that I was updating the hostname after the cluster was created. By doing that, it's like the master didn't know it was the master.

I am still running:

sudo hostname $(curl 169.254.169.254/latest/meta-data/hostname)

but now I run it before the cluster initialization
