Public-network Kubernetes deployment

A Kubernetes cluster for Cozystack can be deployed using only public networks:

• Both management and worker nodes have public IP addresses.
• Worker nodes connect to the management nodes over the public Internet, without a private internal network or VPN.

Such a setup is not recommended for production, but can be used for research and testing, when hosting limitations prevent provisioning a private network.

To enable this setup when deploying with talosctl, add the following data in the node configuration files:

cluster:
  controlPlane:
    endpoint: https://<MANAGEMENT_NODE_IP>:6443

For talm, append the same lines at end of the first node’s configuration file, such as nodes/node1.yaml.
