Add a Windows worker node to MicroK8s

[tphk]

@balchua1

It is the rebuilt cluster and running fine. However, there is also only 1 calico-node and FYI. Thanks!

NAMESPACE NAME DESIRED CURRENT READY UP-TO-DATE AVAILABLE NODE SELECTOR AGE
kube-system calico-node 3 3 3 3 3 kubernetes.io/os=linux 23d
ingress nginx-ingress-microk8s-controller 5 5 3 5 3 16h
kube-system csi-smb-node 3 3 3 3 3 kubernetes.io/os=linux 15h
kube-system csi-smb-node-win 2 2 2 2 2 kubernetes.io/os=windows 15h

This is the state before enabling rbac?

[tphk]

Yes, rbac is not enabled yet

[balchua1]

Looking at this output, im guessing you have 3 linux nodes and 2 windows nodes?

NAMESPACE NAME DESIRED CURRENT READY UP-TO-DATE AVAILABLE NODE SELECTOR AGE
kube-system calico-node 3 3 3 3 3 kubernetes.io/os=linux 23d
ingress nginx-ingress-microk8s-controller 5 5 3 5 3 16h
kube-system csi-smb-node 3 3 3 3 3 kubernetes.io/os=linux 15h
kube-system csi-smb-node-win 2 2 2 2 2 kubernetes.io/os=windows 15h

Just like this csi-smb-node-win DaemonSet where there are 2 pods on windows.

I don’t see it for the calico-nodes on windows.

My guess is that it should have the selector kubernetes.io/os=windows for calico-node DaemonSet.

Fyi, i’ve never tried kubernetes on windows at all tho, but just tryin to help.

Hi, Does anyone know where are the images stored in the node or cluster? In my windows node, I tried to find it by tying docker image ls or ctr image ls; none of them can find any; also in the Linux node, please? Because I tried to delete some images but in vain. Many thanks!

[balchua1]

Try with microk8s ctr images list

[tphk]

Thanks for your reply always. I saw some daemonset images in the Linux nodes but I can’t find any in the windows nodes…by trying both docker image ls or ctr image ls.

[balchua1]

I’ve not tried windows node at all, can you show all calico pods especially those on windows.

Is this article support k8s 1.25.0?

[evilnick]

@bangzhuzhu I haven’t personally tested it on 1.25 but it is certainly intended and expected it should work

The download link to the script changed!
Wrong = https://docs.projectcalico.org/scripts/install-calico-windows.ps1

Correct = https://github.com/projectcalico/calico/releases/download/v3.25.0/install-calico-windows.ps1

[evilnick]

Many thanks for this, I will update accordingly!

This documentation doesn’t appear to work anymore, due to a Calico issue. Windows quickstart results in failing kubelet · Issue #7552 · projectcalico/calico · GitHub

The Calico documentation linked in the Install section also goes nowhere.

[evilnick]

Thanks for reporting, I will check into it

Hi @Karthik_Medam, looks like the Windows node is having trouble contact the Kubernetes API server. Can you share some more details here (or perhaps in a GitHub issue)?

• Did you download the install-calico-windows.ps1 from https://github.com/projectcalico/calico/releases/download/v3.25.1/install-calico-windows.ps1 or somewhere else?
• Which MicroK8s version are you using?
• Is c:\k\config a valid kubeconfig file for the cluster?

Add a Windows worker node to MicroK8s

Hey all, I am trying to set up a mk8s cluster with a windows worker node now and not getting any errors from the installer scripts, but once done my cluster never shows the Windows worker node. I reviewed some of the troubleshooting tips on the Canonical and Calico sites but can’t see what’s wrong here. I am able to use the clusters kubeconfig file on the windows node to interact with the cluster via kubectl and I have reviewed the networking and believe all required ports are open correctly between worker node and control plane… Do you guys have and troubleshooting suggestions for good trou…

I think I am running into this same problem connecting a windows server 2022 Standard to a microk8s cluster running 1.27.2. I follow the steps outlined but when I query for nodes in the cluster after copying the kube config over and starting the kubelet service, but still no windows node. Is there any troubleshooting forum/slack/email that I can request help through?

[evilnick]

sorry you are having an issue. @neoaggelos are there any further testing steps or troubleshooting things we can add here?
