Restart Kubernetes API server with different options
I just found this for a similar use case and the API server was crashing after adding an Option with a file path.
I was able to solve it and maybe this helps others as well:
As described in https://kubernetes.io/docs/reference/setup-tools/kubeadm/implementation-details/#constants-and-well-known-values-and-paths the files in /etc/kubernetes/manifests
are static pod definitions. Therefore container rules apply.
So if you add an option with a file path, make sure you make it available to the pod with a hostPath volume.
in /etc/kubernetes/manifests
is a file called kube-apiserver.json
. This is a JSON file and contains all the option you can set. I've appended the --basic-auth-file=SOMEFILE
and rebooted the system (right after the change of the file kubectl
wasn't working anymore and the API was shutdown)
After a reboot the whole system was working again.
Update
I didn't manage to run the dashboard using this. What I did in the end was installing the dashboard on the cluster. copying the keys from the master node (/etc/kubernetes/admin.conf) to my laptop and did kubectl proxy
to proxy the traffic of the dashboard to my local machine. Now I can access it on my laptop through 127.0.0.1:8001/ui
