Contoh, untuk mengupgrade ke current stable release:
curl -sfL https://get.k3s.io | <EXISTING_K3S_ENV> sh -s - <EXISTING_K3S_ARGS>
Jika ingin mengupgrade ke versi terbaru dari channel yang spesifik (misal latest) maka dapat di baut spefisik untuk nama channel nya:
curl -sfL https://get.k3s.io | INSTALL_K3S_CHANNEL=latest <EXISTING_K3S_ENV> sh -s - <EXISTING_K3S_ARGS>
Jika ingin mengupgrade ke versi yang spedifik, bisa menjalankan perintah berikut :
curl -sfL https://get.k3s.io | INSTALL_K3S_VERSION=vX.Y.Z+k3s1 <EXISTING_K3S_ENV> sh -s - <EXISTING_K3S_ARGS>
jika ingin mengupgrade namun tanpa menjalankannya secara otomatis untuk k3s, maka bisa menambahkan argument INSTALL_K3S_SKIP_START=true .
Contoh hasil output :
