To add the node where you run Rancher Server on a cluster, replace the default ports -p 80:80 -p 443:443 as follows and use the following command to start Rancher:

$ docker run -d --restart=unless-stopped 
 -p 8080:80 -p 8443:443 rancher/rancher:latest

In this case, Rancher Server will be accessible through https://localhost:8443 instead of the standard 443 port.
