Network Connectivity
Description of the Networking Connectivity needed by Talos Linux
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 kubernetes. 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, control plane nodes |
| TCP | Inbound | 50001* | trustd | Worker nodes |
Ports marked with a
