Description Wouter Hummelink 2018-02-06 12:24:49 UTC

Description of problem:
kubeadm 1.9 relies on kubelet config provided by the kubeadm package to set --bootstrap-kubeconfig=/etc/kubernetes/bootstrap-kubeconfig.conf. The absence of this option causes kubelet startup to fail.

Version-Release number of selected component (if applicable):
kubernetes-client-1.9.1-2.fc27.x86_64
kubernetes-node-1.9.1-2.fc27.x86_64
kubernetes-kubeadm-1.9.1-2.fc27.x86_64

How reproducible:
kubeadm join appears to finish correctly, however kubelet doesn't start due to missing kubeconfig.

Steps to Reproduce:
1. install kubernetes-kubeadm 
2. bootstrap a cluster using kubeadm init
3. join a node using kubeadm join command returned by kubeadm init

Actual results:
kubelet fails to start

Expected results:
kubelet bootstraps its TLS config and starts using newly generated kubeconfig.

I don't think was actually fixed -- there's no --bootstrap-kubeconfig=/etc/kubernetes/bootstrap-kubeconfig.conf in https://src.fedoraproject.org/rpms/kubernetes/blob/f27/f/kubeadm.conf

Comment 5 Jan Chaloupka 2018-04-17 10:57:53 UTC

Ok, i will add the option in the next update. We are still fighting with the k8s not starting on f27+ with the latest systemd.
