You don't need to create K0sControllerConfig manually, k0smotron will create it automatically based on K0sControlPlane. This should solve the issue.

1 month ago @makhov - Thanks for the response, how will the machine bootstrap be configured if K0sControllerConfig should not be used?
apiVersion: cluster.x-k8s.io/v1beta1
kind: Machine
metadata:

namespace: default
spec:
clusterName: core-5g-cp-cluster
bootstrap:
configRef:

infrastructureRef:
apiVersion: infrastructure.cluster.x-k8s.io/v1beta1
kind: RemoteMachine
name: proxmox-cp-5g-pool-0Also has this kind of scenario been tested before? It will be great to have a sample in the docs

1 month ago k0smotron generates K0sControllerConfig, as well as Machine and RemoteMachine objects automatically based on K0sControlPlane object.
Note, that K0sControlPlane.spec.machineTemplate.infrastructureRef should contain ref to an actual machine template, not the machine. Since it's kind of against the nature of the RemoteMachines, we introduced PooledRemoteMachinewhich can be used with RemoteMachineTemplate. Here are some docs and an example of how to use it:
https://docs.k0smotron.io/stable/capi-remote/#using-remotemachines-in-machinetemplates-of-higher-level-objects
Here is the full example that we use in our tests: https://github.com/k0sproject/k0smotron/blob/main/inttest/capi-remote-machine-template/capi_remote_machine_template_test.go#L262

1 month ago Great, the controlplane is working now. By default, k0s doesn't run any workloads on the control nodes. To enable it you need to add --enable-worker arg.
Note, that in this case the node-role.kubernetes.io/master:NoExecute taint will be added automatically to the worker node. To disable it, use --no-taints. More info: https://docs.k0sproject.io/stable/worker-node-config/?h=tain#taints
An example:
apiVersion: controlplane.cluster.x-k8s.io/v1beta1
kind: K0sControlPlane
metadata:
name: test-cp
spec:
replicas: 1
k0sConfigSpec:
args:
- --enable-worker
- --no-taints # disable default taints
- ```Thanks, works now and I am able to list the nodes.
While it is working, the k0smotron controller logs is still showing errors that provisioning may not be complete:

1 month ago The controlplane node was created but the status still shows that provisioning failed asper what I posted
Yeah, this false positive ProvisionFailed errors unfortunately sometimes happens, we're working on making it more stable.

Thanks! This is definitely a mistake in our docs, I will fix it!
