Rancher in a highly available Kubernetes cluster">​</a></h2><p>When you install Rancher inside of a Kubernetes cluster, TLS is offloaded at the cluster&#x27;s ingress controller. The possible TLS settings depend on the used ingress controller:</p><ul><li>nginx-ingress-controller (default for RKE1 and RKE2): <a href="https://kubernetes.github.io/ingress-nginx/user-guide/tls/#default-tls-version-and-ciphers" target="_blank" rel="noopener noreferrer">Default TLS Version and Ciphers</a>.</li><li>traefik (default for K3s): <a href="https://doc.traefik.io/traefik/https/tls/#tls-options" target="_blank" rel="noopener noreferrer">TLS Options</a>.</li></ul><h2 class="anchor anchorWithStickyNavbar_LWe7" id="running-rancher-in-a-single-docker-container">Running Rancher in a single Docker container<a href="#running-rancher-in-a-single-docker-container" class="hash-link" aria-label="Direct link to Running Rancher in a single Docker container" title="Direct link to Running Rancher in a single Docker container">​</a></h2><p>The default TLS configuration only accepts TLS 1.2 and secure TLS cipher suites.
