Version v1.2 of the documentation is for the Talos version being developed. For the latest stable version of Talos, see the latest version.

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 kuberenetes. See the kubernetes docs for information on the ports used by kubernetes itself.
