kubelet is not running on control plane node It is critical that the control plane endpoint works correctly during cluster bootstrap phase, as nodes discoverĮach other using control plane endpoint. The health of the backend API servers, to minimize disruptions duringĬommon node operations like reboots and upgrades. This means you can use the IP address(es) of the host to refer to the Kubernetesįor availability of the API, it is important that any load balancer be aware of Meaning that it shares the network namespace with the host. Unlike most services in Kubernetes, the API server runs with host networking, It allows the underlying IP addresses to change without impacting the Using a DNS name here is a good idea, since it allows any other option, while offering BGP peering of a shared IP (such as with kube-vip).The endpoint above may be a DNS name or IP address, but it should beĭirected to the set of all controlplane nodes, as opposed to aĪs mentioned above, this can be achieved by a number of strategies, including: (The port, since it is not the https default of 443 is required.) Such as cert-manager, Let’s Encrypt, or products suchĪs validated TLS certificates are not required.Įncryption, however, is, and hence the URL scheme will always be By default, the Kubernetes API server in Talos runs on port 6443.Īs such, the control plane endpoint URLs for Talos will almost always be of the form Unlike general-purpose websites, there is no need for an upstream CA, so tools ![]() Like Talos’ own API, the Kubernetes API uses mutual TLS, clientĬerts, and a common Certificate Authority (CA). The Kubernetes control plane endpoint is the single canonical URL by which theĮspecially with high-availability (HA) control planes, this endpoint may point to a load balancer or a DNS name which may (this command works before Kubernetes is fully booted). ![]() Kubernetes client configuration can be pulled from control plane nodes with talosctl -n kubeconfig In this guide we assume that Talos client config is available and Talos API access is available. ![]() Troubleshoot control plane failures for running cluster and bootstrap process.
