Since 0.37, many requests to the k8s API now go through a mutating webhook (lineage-controller-webhook). Since the lineage webhook makes multiple requests to the k8s API and, indirectly, to the Cozystack API server, each request for, e.g., creating a secret now causes a lot of chatter between the webhook, the k8s API, and the Cozystack API. When this happens cross-node or, worse yet, cross-zone, this can blow up the latency for simple requests. This patch changes the Cozystack API to a DaemonSet targetting controlplane nodes, configures its service for an `Local` internal traffic policy and adds environment variables indicating that the k8s API server is to be found at <hostIP>:6443, **not only for the Cozystack API, but also for the lineage-controller-webhook.** This is a valid configuration in most scenarios, including the default installation method on top of Talos Linux in Cozystack, however, if this is not valid in your environment, you must now set the values `.lineageControllerWebhook.localK8sAPIEndpoint.enabled` and `.cozystackAPI.localK8sAPIEndpoint.enabled` to `false` in the respective system Helm releases. ```release-note [api,lineage] Configure all chatter between the Lineage webhook, the Cozystack API server and the Kubernetes API server to be confined to a single controlplane node, improving k8s API latency. ``` Signed-off-by: Timofei Larkin <lllamnyp@gmail.com>
