I’m confused about the HA setup on Rancher 2.0.8. I understand 2.0.8 is not HA yet, and this is coming on 2.1. So, the HA setup is only for kubernetes and rancher still runs on top of a single instance.

So, what exactly is the difference between following the HA setup deployment or using docker to run rancher and then starting 3 master/etcd nodes from rancher using the UI?

Why every page says I shouldn’t deploy rancher through docker for production, if the result seems to be the same? Or am I missing something?

2.1 is already available. 1 server pod running on a HA cluster still fixes itself if a node dies or similar. One standalone container running on one host does not.

Right, makes sense. Thanks!
