In a previous post we installed a k3s node as a master and in this post we will add another node, a agent node in this case.
Retrieve the server token from the master node:
$ cat /var/lib/rancher/k3s/server/node-token K102xxxxxxxxxxx::server:xx
From the new agent node, run the installation and pass the k3s_token as an environment variable, and provide the master endpoint:
$ curl -sfL https://get.k3s.io | K3S_TOKEN= K102xxxxxxxxxxx::server:xx sh -s - agent --server https://192.168.0.2:6443
Then from the master node, view the nodes in the cluster:
$ kubectl get nodes NAME STATUS ROLES AGE VERSION rpi-06 Ready master 24h v1.18.2+k3s1 rpi-05 Ready <none> 6m44s v1.18.2+k3s1
