Did some smoke tests… I shutdown the Rancher 2.0 container and:
- I could no longer use
kubectl
- I killed the main process inside of the containers for a deployment with replicaset of > 1 and the containders/pods were recreated.
So the impact of not having Rancher in HA is that you won’t be able to manage your things very well while it’s down, but your workload is still up and still being supervised (at least from the results of this smoke test).
