It&rsquo;s important to understand that Rancher does not create outbound connections to downstream clusters for gaining access to the Kubernetes API endpoint. This includes Rancher deployed clusters and imported clusters.</p> <p><img src="../images/rancher-architecture-rancher-api-server.svg" alt="rancher-architecture"></p> <p>There are two different agent resources deployed on Rancher managed clusters:</p> <ul> <li>cattle-cluster-agent</li> <li>cattle-node-agent</li> </ul> <h2 id="cattle-cluster-agents">cattle-cluster-agents</h2> <p>In Rancher v2.5, the cattle-cluster-agent Deployment has a single replica; in Rancher v2.6, it runs as at least two replicas for HA. When this pod starts, it creates a WebSocket connection to Ranchers API.</p>https://support.tools/training/rancher/rancher-certs/Fri, 29 Apr 2022 02:03:30 -0500https://support.tools/training/rancher/rancher-certs/<h2 id="what-are-ssl-certs">What are SSL Certs?</h2> <p>Generally referred to as a cert or certificate, an SSL certificate authenticates a website&rsquo;s identity and enables an encrypted connection. A web browser and a server create an encrypted link using Secure Sockets Layer or SSL.</p> <p>In short: SSL ensures the data exchanged between two systems is kept private. When you see a padlock icon next to the URL in the address bar, SSL protects the connection between you and the website you are visiting.</p>
