Configuring Network Connectivity

Configuring Network Connectivity

The simplest way to deploy Talos is by ensuring that all the remote components of the system (talosctl, the control plane nodes, and worker nodes) all have layer 2 connectivity. This is not always possible, however, so this page lays out the minimal network access that is required to configure and operate a talos cluster.

Note: These are the ports required for Talos specifically, and should be configured in addition to the ports required by kuberenetes. See the kubernetes docs for information on the ports used by kubernetes itself.

Control plane node(s)

Protocol Direction Port Range Purpose Used By
TCP Inbound 50000* apid talosctl
TCP Inbound 50001* trustd Control plane nodes, worker nodes

Ports marked with a * are not currently configurable, but that may change in the future. Follow along here.
