Can we launch Rancher2.0 with an External Database, like the Rancher1.6 Version. Can anyone guide me here?
2.0 uses etcd as its persistent store, not MySQL like 1.x
By default 2.0 runs an internal etcd cluster, but if you run Rancher 2.0 in an existing k8s cluster then it will leverage the host cluster’s etcd store — making it “external” to Rancher the same way MySQL was.
Hope that helps.
