Now you have a highly available control plane. Joining additional worker nodes to the cluster follows the same procedure as a single server cluster.
There are a few config flags that must be the same in all server nodes:
* Network related flags: `--cluster-dns`, `--cluster-domain`, `--cluster-cidr`, `--service-cidr`
* Flags controlling the deployment of certain components: `--disable-helm-controller`, `--disable-kube-proxy`, `--disable-network-policy` and any component passed to `--disable`
* Feature related flags: `--secrets-encryption`

> **Note:** Ensure that you retain a copy of this token as it is required when restoring from backup and adding nodes. Previously, K3s did not enforce the use of a token when using external SQL datastores.
