When setting up Rancher via its Docker container, you are not able to configure SSL termination out-of-the-box. Instead the Rancher documentation gives some advice on how to set up SSL termination via nginx or Apache. But why would you install such a service on the host when Rancher is running in a container? Ideally the SSL proxy would also run in a container. Searching on Docker Hub for a solution, I found the dictcp/rancher-ssl image that provides exactly that. The set up is trivial.
