Hello all!
Has anyone enabled alpha features feature-gates on k8s cluster (v1.9.3)?
I want to enable TaintBasedEvictions in order for a node controller will automatically taint a node when certain condition is true (unreachable/not-ready).
I already added this flag “–feature-gates=TaintBasedEvictions=true” on apiserver & controller manager and while the controller taints the problematic node automatically:
Taints: node.kubernetes.io/unreachable:NoExecute (just reproduce it with shutdown of docker service in a node), it doesn’t evict the pods as it should.
Any idea anyone ?
