Rancher Server HA

Is there a way to accomplish HA on Rancher Servers 2.0?
In 1.6 i could use a database, but now i didn’t know how.


I believe Rancher 2.x is using etc.d instead of MySQL. Instead of having to setup a Galera Cluster for MySQL as in 1.x; In 2.x, you assign multiple (3+) nodes to the etc.d role.
