|
To add more nodes to a Talos Linux cluster, follow the same procedure as when initially creating the cluster:
|
|
|
|
- boot the new machines to install Talos Linux
|
|
- apply the `worker.yaml` or `controlplane.yaml` configuration files to the new machines
|
|
|
|
You need the `controlplane.yaml` and `worker.yaml` that were created when you initially deployed your cluster.
|
|
These contain the certificates that enable new machines to join.
|
|
|
|
Once you have the IP address, you can then apply the correct configuration for each machine you are adding, either `worker` or `controlplane`.
|
|
|
|
```bash
|
|
talosctl apply-config --insecure \
|
|
--nodes [NODE IP] \
|
|
--file controlplane.yaml
|
|
```
|
|
|
|
The insecure flag is necessary because the PKI infrastructure has not yet been made available to the node.
|
|
|
|
You do not need to bootstrap the new node.
|
|
Regardless of whether you are adding a control plane or worker node, it will now join the cluster in its role.
