install
ubuntu@k0s-ctrl:~$ curl --proto '=https' --tlsv1.2 -sSf https://get.k0s.sh | sudo sh ubuntu@k0s-ctrl:~$ k0s version v1.31.1+k0s.1
Crea il servizio systemd:
ubuntu@k0s-ctrl:~$ sudo k0s install
Bootstrap controller
Bootstrap del nodo controller (non single mode)
ubuntu@k0s-ctrl:~$ sudo mkdir -p /etc/k0s ubuntu@k0s-ctrl:~$ k0s config create | sudo tee /etc/k0s/k0s.yaml ubuntu@k0s-ctrl:~$ sudo k0s install controller -c /etc/k0s/k0s.yaml ubuntu@k0s-ctrl:~$ sudo systemctl start k0scontroller.service
Verifica:
ubuntu@k0s-ctrl:~$ sudo k0s status
Version: v1.31.1+k0s.1
Process ID: 7885
Role: controller
Workloads: false
SingleNode: false
creazione worker
Sul controller creare un token (si può redirigere su file)
ubuntu@k0s-ctrl:~$ sudo k0s token create --role=worker --expiry=100h
Sul candidato nodo installare k0s con curl (vedi sopra) e copiare il token generato nel controller in un file (es k8s_worker_token)
ubuntu@a6:~$ sudo k0s install worker --token-file ./k8s_worker_token ubuntu@a6:~$ sudo k0s start <(code> Verificare il successo dell'operazione sul controller <code> ubuntu@k0s-ctrl:~$ kubectl get node NAME STATUS ROLES AGE VERSION a6 Ready <none> 4m6s v1.31.1+k0s
k0s incorpora kubectl
, che fa prefissato da k0s
. Esempio:
ubuntu@k0s-ctrl:~$ sudo k0s kubectl cluster-info
