Hi, I’m really struggling to get this installed, any help gratefully received.
I’m trying to install k3s on a master and a worker node, both running Ubuntu 22.04, bare-metal. The master installs no problem but the worker hangs on [INFO] systemd: Starting k3s-agent. The log files on the worker say:
Oct 27 14:22:32 myworker k3s[69044]: E1027 14:22:32.202428 69044 server.go:291] "Unable to authenticate the request due to an error" err="Post \"https://127.0.0.1:6444/ap>
Oct 27 14:22:32 myworker k3s[69044]: E1027 14:22:32.230764 69044 controller.go:144] failed to ensure lease exists, will retry in 7s, error: Get "https://127.0.0.1:6444/ap>
Oct 27 14:22:32 myworker k3s[69044]: E1027 14:22:32.288643 69044 kubelet.go:2448] "Error getting node" err="node \"myworker\" not found"
The master can see the worker node but it says “NotReady”:
NAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME
myWorker NotReady <none> 20h v1.25.3+k3s1 192.168.196.6 <none> Ubuntu 22.04.1 LTS 5.15.0-52-generic docker://20.10.20
myMaster Ready control-plane,master 20h v1.25.3+k3s1 192.168.196.4 192.168.196.4 Ubuntu 22.04.1 LTS 5.15.0-52-generic docker://20.10.20
I’ve installed docker and it’s running on both master and worker. They are both on an internal subnet. I’ve another server which I tried to set up as a worker node which has the same issue.
I’ve tried several different ways of installing the master node after looking here :
curl -sSL https://get.k3s.io | INSTALL_K3S_EXEC="server --docker --debug --node-external-ip=<master-ip> --advertise-address=<master-ip>" sh -
curl -sSL https://get.k3s.io | INSTALL_K3S_EXEC='server --docker' sh -
curl -sfL https://get.k3s.io | INSTALL_K3S_EXEC="--write-kubeconfig ~/.kube/config --write-kubeconfig-mode 666 --tls-san <master-ip> --node-external-ip=<master-ip>" sh -
and the install for the worker node seems fairly standard, I’ve tried it with and without the docker flag:
curl -sfL http://get.k3s.io | K3S_URL=https://<master-ip>:6443 K3S_TOKEN=${TOKEN} sh -s - --docker
I’ve opened ports:
sudo ufw allow 443/tcp
sudo ufw allow 6443/tcp
Obtained the token:
cat /var/lib/rancher/k3s/server/node-token
created the directories .kube and config, copied the config over:
sudo cat /etc/rancher/k3s/k3s.yaml > /home/ubuntu/.kube/config/k3sconfig.yaml
changed permissions:
chown ubuntu /home/ubuntu/.kube/config/k3sconfig.yaml
chgrp ubuntu /home/ubuntu/.kube/config/k3sconfig.yaml
It looks like the worker node is having issues, rather than the connection to the master.
I’m at a loss. Thanks in advance.
