Hi everyone I'm trying to set a node taint but it doesn't seem to be working I'm currently passing the following argument:

--node-taint <http://node-role.kubernetes.io/master=true:NoSchedule|node-role.kubernetes.io/master=true:NoSchedule>

but my master nodes still show

Taints: <none>

when I check the node annotations

<http://k3s.io/node-args|k3s.io/node-args>

contains

[..., "--node-taint", "<http://node-role.kubernetes.io/master=true:NoSchedule|node-role.kubernetes.io/master=true:NoSchedule>"]

I use

--node-taint CriticalAddonsOnly=true:NoExecute

to block regular workloads from going to the control-plane nodes.

cool I'll give it a go thanks

https://docs.k3s.io/advanced#node-labels-and-taints

K3s agents can be configured with the options --node-label and --node-taint which adds a label and taint to the kubelet. The two options only add labels and/or taints at registration time, so they can only be set when the node is first joined to the cluster

Yeah sorry I wasn’t clear about that fact. Of course not 🙏

yeah I did that and it worked thanks
