I want to set up a Rancher server and 3 nodes, all on EC2 instances.
I have already set up a classic ELB in front of the server, and it is reachable over https via the public internet.
When trying to add the nodes (hosts), the ui is asking for a “base url” that the nodes will use to reach to the master.
It is proposing the https url/alias for my elb (e.g. https://mycustomaddress.foo.com) that I use to view the ui.
However, when inside an (another) existing instance:
Should I use the private IP of the instance on which Rancher server resides?
